What AI Actually Is
Before you can work effectively with AI, you need to understand what it is. Not the marketing. Not the hype. The actual technology.
01. The Core Idea
- A magical brain in a computer
- A search engine that answers questions
- Something that "knows" things like a person
- Always right, or at least always trying to be
- A pattern-matching engine trained on text
- A tool that predicts useful responses to prompts
- Something that generates, never retrieves
- Confident regardless of whether it is right
02. The Three Ingredients
Billions of documents, code, conversations. The raw material AI learned from. It does not "reference" this data at runtime. The patterns are compressed into the model itself.
A mathematical representation of all those patterns. Think of it as a giant map of how language works. The model is static after training. It does not learn from your conversations.
When you type a prompt, the model runs a prediction to generate a response. This is not "search" or "retrieval." It is generation from statistical patterns, every single time.
03. What This Means for You
- AI can produce novel combinations, new ideas, creative approaches
- It adapts to your style, your context, your tone
- It can reason through problems step by step
- It is tireless and never gets frustrated
- AI can be confidently wrong (hallucination)
- It has no internal truth check. It sounds convincing either way
- It does not know when it does not know
- It will tell you what sounds right, not what is right
04. What AI Is NOT
- Not a search engine. It does not retrieve facts from the internet
- Not a database. It does not store or recall specific records
- Not conscious. It has no feelings, opinions, or self-awareness
- Not magic. It is math and statistics applied to language
- A pattern-recognition engine trained on text
- A reasoning tool that follows instructions
- A tireless assistant that never gets bored
- A skilled collaborator on first drafts and exploration
Think of AI as a brilliant intern who just joined your team. They have read every book in the library (training data) but have no idea how your specific company works. They need clear instructions, examples of good work, and someone to check their output before it goes to a client. The intern is fast and never sleeps. But they still need you to be the editor.
How AI Changed (And Why It Matters)
AI did not suddenly appear. It evolved through distinct phases. Understanding these phases explains why today's AI works differently than what you may have tried before.
01. The Three Phases of Modern AI
Phase 1: Rules + Search (Pre-2022)
Old AI was rigid. Chatbots followed decision trees. Search engines ranked keywords. Predictable but brittle. If you asked a question slightly outside their rules, they broke.
Phase 2: The Breakthrough (Late 2022)
Large Language Models. Trained on massive text, AI learned language on its own. Suddenly it could hold a conversation, write, explain, summarize. Flexible in a way old AI never was.
Phase 3: From Chat to Work (2024-2025)
AI moved from answering questions to doing work. Reading files, writing to folders, executing multi-step tasks. The interface changed from chat box to workspace. Most people have not absorbed this yet.
02. Old Mental Model vs. New
- Chat with AI like a smarter Siri
- Ask one question, get one answer
- Copy/paste results manually
- No context carried forward
- AI is a tool you use occasionally
- Delegate work to AI like a teammate
- Set context, iterate, verify
- AI reads and writes files directly
- Context files persist across sessions
- AI is a collaborator you work with daily
03. Why This Confuses People
The technology moved faster than our mental models. Most people's first experience was ChatGPT in late 2022. So they have spent years thinking of AI as "a thing you chat with." But the technology underneath changed dramatically. The interface looks the same. The capability is fundamentally different.
The bottom line: Every 12-18 months, the capability shifts meaningfully. The specific tools and models will keep changing. But the skills you learn here, context, delegation, verification, collaboration, will apply regardless of what comes next.
Strengths & Limits
Effective use of AI starts with knowing what to give it and what to keep. This is not about capability tiers. It is about fit.
01. What AI Excels At
Condensing long documents, meetings, transcripts into clear, structured summaries with key points and action items.
First drafts, emails, proposals, reports, content. Give it context and it produces a strong starting point to refine.
Comparing options across criteria, finding patterns in text data, identifying gaps or inconsistencies in documents.
Generating ideas, frameworks, approaches. AI is excellent at producing many options quickly for you to evaluate.
Restructuring information, changing tone, translating between languages, turning notes into polished formats.
Summarizing known topics, explaining concepts, providing overviews. Use it to get oriented, not as a source of truth.
02. What AI Is Bad At
AI will confidently state false information. It does not know when it is wrong. Everything must be checked.
Unless connected to search, AI knowledge has a cutoff date. It does not know what happened yesterday.
Surprisingly bad at arithmetic and precise math. Always verify numbers, calculations, and data.
AI does not know your internal data, customer history, or company processes unless you provide them.
AI cannot make value judgments about your brand, your relationships, or your strategic decisions.
AI may give different answers to the same question. It is probabilistic, not deterministic.
03. The Critical Distinction
The most important skill is knowing which tasks go where. Not every task belongs in AI. Not everything needs a human. The art is recognizing the fit.
- First drafts and rough cuts
- Summaries and compilations
- Comparisons and analysis
- Formatting and restructuring
- Brainstorming and exploration
- Repetitive writing tasks
- Strategic decisions and direction
- Final approval and sign-off
- Relationship-sensitive communication
- Anything requiring personal judgment
- Verification of AI output
- Creative vision and taste
04. The Competency Map
| Task Type | AI Strength | Human Requirement |
|---|---|---|
| Summarize a meeting transcript | High | Verify key decisions, add context |
| Draft a client email | High | Review tone, personalize, approve |
| Calculate quarterly numbers | Low | Use a spreadsheet, verify formula |
| Research a competitor | Medium | Cross-check facts, add insider knowledge |
| Write a strategic plan | Medium | Define strategy, review for alignment |
| Decide whether to fire a client | Low | Human judgment only |
Before you send a task to AI, ask yourself: would I be comfortable letting someone else make the final call on this? If yes, AI can own the draft. If no, you need to own the decision and use AI for support only.
How to Think About
New Tools
New AI tools and models launch constantly. The framing you use to evaluate them matters more than the features themselves.
01. The Fundamental Question
Every new AI announcement triggers the same cycle: hype, panic, confusion, "will this replace my job?" The useful question is not "is this the best AI?" The useful question is: what does this tool change about how I work?
02. The Evaluation Framework
When a new tool or model appears, run it through these three questions:
Does it change the interface?
Is this still "I give instructions, AI produces output, I verify"? Most tools do not change this. If the interaction model is the same, the skills transfer.
Does it access new data?
Can it read your files, search the web, query your database? This changes what you can give it, not how you work with it.
Does it change who verifies?
This is the critical question. If the tool makes autonomous decisions without human review, that is a real shift. Most tools still put you in charge.
03. What Actually Changes vs. What Does Not
- Speed. Responses get faster
- Context capacity. Can handle more input
- Instruction following. More precise adherence
- Reasoning quality. Better logic and analysis
- Fewer hallucinations. But never zero
- You still provide context and instructions
- You still verify the output
- You still apply your judgment
- You still own the result
- You still need to know what you want
04. The Trap of "Just Wait for the Next One"
A common reaction to fast-moving technology is paralysis: "why learn today's tool when next month's will be better?" This is a mistake. The skills you build now, giving clear context, iterating on output, verifying results, applying judgment, transfer to every future tool.
What compounds: The ability to think clearly about what you want, express it precisely, evaluate what you get, and guide it toward what works. Those skills do not become obsolete. They become more valuable as the tools get faster.
The Human Role
AI does not replace judgment. It exposes it. The more AI does, the more your taste, your standards, and your decisions matter.
01. You Are the Editor
Every AI output is a draft. Nothing leaves your desk without your review. This is not a bug. It is the design. AI handles the labor of generation. You handle the labor of judgment. That division is not diminishing your role. It is clarifying it.
02. What Only You Can Do
03. The Taste Gap
As AI gets better at producing competent output, the differentiator becomes taste. Two people can give AI the same task. One gets something mediocre because they accept the first output. One gets something excellent because they know what to ask for, what to reject, and what to refine. The difference is not AI skill. It is taste.
04. The Trust Paradox
People new to AI tend to either trust it too little or trust it too much. The right relationship is trust but verify. Trust AI to handle the heavy lifting. Verify everything before it goes out the door.
- Ignore AI because it is "not perfect"
- Miss the 80% time savings on drafts
- Do everything from scratch
- Get outpaced by peers who use it
- Send AI output without review
- Assume AI is correct because it sounds confident
- Skip verification steps
- Send something that is wrong or off-brand
- Let AI generate. Review everything before it ships
- Trust AI for drafts, research, exploration. Verify facts, tone, and alignment
- Use AI to augment your judgment, not replace it
How to Read
AI Output
The single most underrated AI skill is not prompting. It is reading. Knowing what to look for determines whether you catch errors or miss them.
01. The Fluency Problem
AI output reads fluently. That is the problem. Bad AI output does not look wrong. It looks perfectly reasonable. The sentences are grammatical. The structure is logical. The tone is confident. This fluency makes us lower our guard. But AI does not know what it is talking about. It sounds like it does.
02. The Two-Pass Reading Method
Pass 1: Substance Scan
Read for facts, claims, numbers, names, dates. Does anything seem off? Flag everything questionable before refining.
Pass 2: Fit Check
Read for tone, audience, purpose. Does this match the brief? Does it sound like your company? This pass is about alignment, not correctness.
03. Common Failure Modes
AI states false information confidently. Names, dates, events, statistics. These look real but are invented. Always verify specific claims.
AI agrees with you even when you are wrong. If you ask "isnt this the right approach?" AI will likely say yes. Push back and ask it to challenge you.
AI reduces complex topics to surface-level summaries. It misses nuance, trade-offs, and edge cases. Dig deeper on complex subjects.
AI invents specifics to sound authoritative. "According to a 2023 Gartner report..." when no such report exists. Watch for plausible-sounding citations.
04. The Verification Checklist
Before you use any AI output, check:
- Are the facts verifiable? (names, dates, numbers, citations)
- Does the tone match the audience and purpose?
- Are there any claims that seem too good (or bad) to be true?
- Does it miss important context that only you know?
- Would you be comfortable putting your name on this?
Claude writes: "According to a 2024 McKinsey study, companies using AI saw a 40% increase in productivity." Sounds credible. Sounds specific. But is it real? If you cannot verify the source, do not use the claim. Always ask Claude for specific, verifiable citations on factual claims.
AI Safety & Privacy
Using AI effectively means using it responsibly. Understanding what data goes where, and what to keep private, is not optional.
01. The Core Rule: What You Put In Matters
Everything you type into an AI tool is processed by that company's servers. This includes prompts, documents you upload, and any personal or proprietary information you include. The general rule: do not put anything into an AI tool that you would not put in an email to a contractor.
02. Data Handling by Platform
| Platform | Data Use Policy | Key Consideration |
|---|---|---|
| claude.ai (Free/Pro) | Not used for training by default | Anthropic does not train on your API or claude.ai data. You can opt in to share for improvement. |
| Claude API | Not used for training | Data is processed but not retained for training. Enterprise-grade data handling. |
| Claude Team/Enterprise | Not used for training | SOC 2 compliant. Data never leaves your trust boundary. Includes admin controls. |
| ChatGPT (Free/Plus) | Used for training unless opted out | By default, conversations may be used for training. Opt out in settings. Team/Enterprise versions exclude training use. |
03. Privacy Best Practices
- Public information and research
- Your own writing and notes
- Anonymized scenarios and data
- General business context (without names)
- Things you would put in a shared doc
- Passwords, credentials, API keys
- Personal health information (PHI)
- Customer PII (names, emails, addresses)
- Confidential financial data
- Trade secrets or proprietary code
04. The Hallucination Risk (Revisited)
Hallucination is not just a quality issue. It is a safety issue. If AI invents a statistic that makes it into a client presentation, or fabricates a legal precedent that gets cited in a contract, that is a real-world harm.
05. The Trust Boundary
Know your company's policy
Your company may have specific rules about which AI tools are approved and what data can be shared.
Check before sharing client data
If you handle client information, verify whether your AI tool is approved for that level of data.
Use enterprise tiers for sensitive work
Free tiers do not offer the same data protections as enterprise or API-based access.
When in doubt, leave it out
If you are unsure whether data is safe to share, do not share it. Anonymize or skip AI for that task.
The Collaboration
Pattern
This is the pattern that ties everything together. A repeatable loop for working with AI, regardless of tool, model, or task.
01. The Core Loop
Every interaction with AI follows the same four-step pattern. Master this pattern and you can work effectively with any AI tool.
Orient
Set context. Who are you? What are you trying to do? What does success look like? This step determines everything that follows.
Direct
Give clear instructions. What role should AI take? What format? What constraints? Vague direction produces vague results.
Review
Read the output critically. Check facts, tone, alignment. Does this meet the bar? If not, what needs to change?
Iterate
Refine. Tell AI what to adjust. Give feedback on what worked and what did not. Stop when it is good enough, not when it is perfect.
02. Surface-Level vs. Deep Collaboration
- One-shot prompts. Accept first output
- No context provided upfront
- Vague instructions ("make it better")
- No iteration or refinement
- Starts fresh every time
- Rich context and examples upfront
- Clear success criteria defined
- Multiple rounds of refinement
- Feedback that teaches AI your preferences
- Builds on shared context over time
03. The Feedback Loop
AI learns nothing from a single conversation. But you learn something from every interaction. Each time you refine your prompt, each time you catch an error, each time you clarify your instructions, you are building a skill that transfers to every future interaction.
The compounding effect: The first time you use AI for a task, it might take as long as doing it yourself. The third time, half as long. The tenth time, a quarter of the time. The skill is not in the tool. The skill is in your ability to orient, direct, review, and iterate efficiently.
04. Common Anti-Patterns
Dumping everything into one prompt. AI gets overwhelmed. Break complex tasks into smaller conversations.
Keeping one conversation going for weeks. Context window fills. Quality degrades. Start fresh, bring context forward.
Accepting first output without review. Misses errors and opportunities for improvement. Always review.
"Make this better." AI has no idea what "better" means. Be specific about what you want.
05. The Meta-Skill
The collaboration pattern applies whether you use Claude, ChatGPT, Gemini, or a tool that does not exist yet. The interface will change. The models will get smarter. The pattern will remain the same.
06. Durable Skills Summary
| Skill | Why It Lasts |
|---|---|
| Context setting | Every AI tool works better with clear context. This will never change. |
| Instruction clarity | Specific direction beats vague requests regardless of model capability. |
| Critical reading | AI output always needs human review. The better AI gets, the more subtle the errors. |
| Iteration | First drafts are starting points. Refinement is where quality comes from. |
| Verification | Trust but verify. This applies to every AI tool, every model, every output. |
| Judgment | AI proposes. You decide. That division is permanent. |
Why Set Up Claude?
AI is everywhere. So why invest time in this tool, this setup, this workflow? Because the difference between "trying AI" and "integrating AI into how you work" is the difference between a toy and a transformation.
08-01 · The Real Cost of Not Setting Up
- Tab-hopping between tools, losing context each time
- Mental overhead: remembering everything yourself
- Starting from scratch on every project
- Scattered notes, no shared memory
- Repeating the same work daily
- No system for leveraging AI output
- One workspace for thinking, writing, and creating
- Claude holds your project context, you hold the vision
- Reusable templates and workflows
- Structured context files that persist between sessions
- Compound productivity: each session builds on the last
- A system that amplifies your thinking
08-02 · AI as Your Second Brain
Your biological brain is great at creative leaps, intuition, and judgment. It is terrible at holding lots of details, processing large documents, and remembering everything. Claude fills those gaps.
Externalize memory
Instead of keeping project details, requirements, and context in your head, put them in Claude's context window. Free your mental RAM for higher-level thinking.
Think in public
Use Claude as a thinking partner. Draft ideas, get feedback, explore angles. Seeing your thoughts reflected and reshaped by AI clarifies your own thinking.
Process at scale
Claude reads faster than you. Paste a 50-page document, a codebase, a research paper. Ask questions about it. Claude has already read it.
Build a knowledge base
Your project folder becomes your shared context. Documents, notes, examples, and guidelines that Claude references consistently, every single conversation.
Iterate faster
First draft in seconds. First revision in another pass. By the time you'd normally start writing, you're already refining. Speed without sacrificing quality.
08-03 · What Setup Unlocks
Your project folder with instructions, examples, and guidelines. Claude reads it every session. No more repeating yourself.
Templates and patterns that enforce your standards. Same quality, every time, regardless of how you phrase the prompt.
Save prompt patterns for common tasks. Don't reinvent the wheel for every email, document, or analysis.
Claude connects to your codebase, files, and tools. One interface for writing, coding, analyzing, and creating.
08-04 · What Setup Is (And Isn't)
- Hours of configuration before you see value
- Learning to code or becoming a prompt engineer
- Replacing your judgment with AI
- A one-time task you do and forget
- A 15-minute investment that pays off every single day
- Creating a project folder and a few context files
- Learning a delegation framework you can use anywhere
- An evolving system that gets better as you use it
The Way You Work
Is About to Change
This isn't a technical training. You don't need to know how to code. You just need to know how to delegate.
01-01 · Old Paradigm vs. New Reality
- Treat AI like a search engine, ask once, move on
- Zero context provided
- Treats AI as "magic answer box"
- One-shot prompts, no iteration
- No follow-through or verification
- Starts fresh every single time
- Delegate like a teammate, set context, iterate, verify
- Rich context and examples upfront
- Treats AI as a skilled collaborator
- Iterative refinement loop
- Verify and validate all outputs
- Builds on shared understanding
01-02 · Tokens: How AI Reads Your Words
AI doesn't read words like we do. It reads in "tokens", chunks of text about ¾ of a word long.
1 token ≈ ¾ of a word in English. "Hello" = 1 token. "Collaboration" = 2-3 tokens.
Claude can hold ~200K tokens in memory at once, roughly a 300-page book.
When the limit fills, Claude forgets the oldest context first. This is why long chats degrade.
Non-English text uses more tokens per word. Plan accordingly if working multilingually.
01-03 · The Context Window: How AI Remembers
01-04 · The Beginner Trap: Why Conversations Break
You ask Claude something → It works great → You ask something else → Works less well → You add more instructions → Context window fills up → Claude "forgets" the beginning → "Why is it getting worse?"
• Long conversation? Start a fresh one with ALL the context re-pasted
• Different task? Start fresh. Don't pile onto old conversations.
• Complex task? Break it into smaller conversations.
01-05 · The 4-Step Delegation Flow
Give context
Background, audience, goal, constraints, before anything else.
Set expectations
Tone, format, length, what success looks like.
Define the task
Clear, specific instructions, not vague requests.
Iterate & verify
Review, refine, check for correctness. First draft = starting point, never final.
01-06 · Exercise: Reflect on Your Current Use
Part 2. Write (3 min): Write one task you do regularly that you'd like AI to help with more effectively.
Part 3. Share (optional): What's one way your current use could improve with the "delegation" mindset?
Meet Your
New Teammate
Claude is not just a chatbot. In 2026, it's six tools. Most people only use one of them.
02-02 · What Is Claude?
Claude is an AI assistant created by Anthropic, a company founded by former OpenAI researchers. Built for collaboration, not just chat.

- Brainstorm and plan projects
02-06 · Our Recurring Example: Meeting → Email
We'll use this scenario throughout the entire training to see how each skill applies:
The scenario: You just attended a 45-minute client meeting. Now you need to: (1) write a meeting summary, (2) draft a follow-up email, (3) create an action item list.
30-45 minutes of writing, checking, and formatting, from scratch, every time.
5-10 minutes of directing, reviewing, and refining, using context you already have.
02-07 · Exercise: What Would You Use Claude For?
Part 2 (2 min): Share one idea with the group. What task would save you the most time?
Check-in: Has anything surprised you so far? What's still unclear?
Which AI Tool for What
There's no single "best" AI tool. Each has strengths. The skill is matching the tool to the task - and knowing when to use more than one.
11-01 · The AI Tool Landscape
The AI space is crowded. New models launch weekly. But the tools worth knowing fall into a few distinct camps. Each excels in different areas. Your goal is not to pick one - it's to know which to reach for based on the task.
Best for creative writing, voice conversations, image generation (DALL-E), brainstorming, and broad knowledge tasks. Strong plugin ecosystem.
Best for long documents (200K context), complex instruction following, nuanced analysis, coding, and file-aware workspace.
Best for Google Workspace integration (Gmail, Docs, Drive), video understanding, and research with Google Search grounding.
Perplexity (research + citations), GitHub Copilot / Cursor (coding), Midjourney / Canva (image), NotebookLM (research org), ElevenLabs (voice).
11-02 · ChatGPT: Best For
ChatGPT (OpenAI) is the most widely used AI tool. It excels at creative and conversational tasks, and has the broadest feature set including voice, image generation, and a large plugin marketplace.
- Creative writing & storytelling. Fiction, scripts, ad copy. ChatGPT's creative flexibility is top-tier.
- Voice conversations. Advanced Voice Mode is best-in-class. Natural, real-time voice interaction.
- Image generation. DALL-E integration. Generate and iterate on images directly in chat.
- Brainstorming. Excellent at generating many ideas, angles, and approaches quickly.
- Plugin ecosystem. Broadest set of third-party integrations and plugins available.
- Smaller context. 128K tokens vs Claude's 200K. Can't process entire books or massive docs.
- Generic writing. Output can feel more templated and less nuanced than Claude.
- Less precise instruction following. Tends to overshoot or miss complex constraints.
- No file workspace. Can't read/write your project files without third-party plugins.
11-03 · Claude: Best For
Claude (Anthropic) is built for collaboration on complex work - not just conversation. It excels where precision, nuance, and long context matter.
- Long document processing. 200K token context window. Read entire books, months of email, massive codebases.
- Instruction following. Best-in-class at following detailed, nuanced, multi-part instructions.
- Nuanced analysis. Superior at reasoning through complex problems with careful judgment.
- Coding & technical work. Excellent at code review, debugging, architecture analysis.
- File workspace. Cowork Mode reads/writes your actual project files. No copy-paste needed.
- Human-sounding writing. Output reads naturally, not like a template. Less "AI-sounding."
- No image generation. Claude cannot generate images natively.
- Voice is weaker. ChatGPT's voice mode is significantly more advanced.
- Fewer integrations. Smaller plugin ecosystem compared to ChatGPT.
- Higher learning curve. Claude's full power requires setup (context files, Cowork, skills).
11-04 · Gemini: Best For
Gemini (Google) is deeply integrated into the Google ecosystem. Its strongest use case is working with Google Workspace and multimodal understanding.
- Google ecosystem. Direct integration with Gmail, Google Docs, Drive, Sheets. Access your existing content.
- Multimodal understanding. Best video understanding capability. Can reason about video content and audio.
- Web research. Integrated Google Search grounding for real-time, cited information.
- Free tier. Very capable free tier. Excellent for casual users and students.
- Weaker at nuance. Can feel less precise than Claude for complex reasoning tasks.
- Less consistent. Output quality can vary more between use cases.
- Google dependency. Most powerful features require Google Workspace subscription.
- Smaller ecosystem. Fewer third-party integrations and community resources.
11-05 · Specialized AI Tools
Beyond the general-purpose models, specialized tools handle specific tasks better than any generalist. These are worth knowing even if you mainly use Claude or ChatGPT.
AI-powered search engine. Answers questions with citations from live sources. Best for research, fact-checking, and staying current. Not a general assistant - it's search with reasoning.
Code-specific AI. Integrated into VS Code and other IDEs. Best for writing, completing, and debugging code. Not designed for documents, emails, or general tasks.
Image generation. Midjourney for artistic, high-quality images. Canva for design templates and marketing graphics. Use these when you need visuals, not text.
Google's research notebook. Upload documents, it answers questions based only on your sources. Best for deep research on specific materials. No hallucinations outside your sources.
AI meeting notes. Records, transcribes, and summarizes meetings automatically. Best for anyone who attends frequent meetings. Saves hours of manual note-taking per week.
AI voice generation. Best-in-class text-to-speech, voice cloning, and audio content. Use for narration, voiceovers, and audio content. Not for text-based work.
11-06 · The Power User Strategy
Power users don't pick one AI tool. They use 2-3 tools as a system, each for what it does best. The skill is not knowing every feature - it's knowing which tool to reach for and when.
- Claude for analysis, long documents, writing, coding, file work. Your main workspace.
- ChatGPT for creative brainstorming, voice conversations, image generation. Your creative partner.
- Perplexity for research, fact-checking, current events. Your research assistant.
- Gemini for Google Workspace tasks, working with your existing Google docs and emails.
- Use the right tool for the task, not one tool for everything
- The skills you're learning here (context, iteration, verification) transfer to every tool
- Don't chase new models - chase better workflows
- The tool that's best today won't be best in 6 months. The skill of working with AI will still matter.
11-07 · Exercise: Match the Tool
1. You need to analyze a 150-page legal contract and draft a summary with risk flags.
2. You want to generate a hero image for a landing page and brainstorm taglines.
3. You need to research a competitor's recent funding round (announced yesterday) and summarize the key details.
4. You're drafting a client email and need it to sound exactly like you - your tone, your vocabulary, your style.
5. You have 50 files in Google Drive that need to be organized and summarized for a quarterly review.
Discuss (2 min): Share your answers with a partner. Did anyone pick differently? What drove the choice?
How to Talk to Claude
So It Actually Works
Prompting is not about finding "magic words." It's about clearly communicating what you need to a capable teammate.
03-02 · Delegation, Not Magic
If you asked a new team member to write a client email, you'd tell them: who the client is and what they care about, what the email should accomplish, what tone to use, what to include and avoid. The same rules apply to prompting AI.
03-03 · The 6-Part Prompt Framework
"You are a senior copywriter...", gives Claude an expertise lens. Fundamentally changes the output quality.
Background, audience, situation. Claude has no idea who you are. Your job: set the scene.
What exactly should it do? Be specific. "Make it better" tells Claude nothing.
Length, tone, what to avoid. Set the bounds so Claude doesn't overshoot.
Email? Bullet points? Table? Memo? Specify it or Claude will choose for you.
"Flag anything that sounds like a promise we haven't approved." Tell it how to check its own work.
Not every prompt needs all 6, but the more you include, the better the result. Aim for at least 3-4.
03-04 · Rule 1: Give Context (The Most Important Rule)
Why it matters: Claude has no idea who you are, who you're writing to, or what's happened before. Your job is to set the scene.
Claude guesses the client, purpose, and tone. Almost always generic and wrong.
03-05 · Rule 2: Give Examples
Claude learns from patterns. An example is worth 100 words of explanation.
"Write a professional bio."
→ Generic corporate bio that sounds like everyone else.
"Write a professional bio. Here's one I like, notice the tone: [example]. Write mine in the same style."
→ One example replaces paragraphs of instruction.
03-06 · Bad Prompt → Good Prompt
No audience · No tone · No structure · No examples · No constraints · No format
03-07 · Let's Build a Prompt Together (Recurring Example)
Remember our scenario: meeting recap → follow-up email. Here's a prompt built step by step:
03-08 · Practice: Rewrite a Weak Prompt
Here's a weak prompt. Let's improve it together:
"Write a status update for the project."
• What's missing? (Context, audience, format, tone)
• What would make this specific? (Which project? To whom? How much detail?)
• What should it include? (Progress, blockers, next steps?)
The rewrite should include: Role, Context (what project phase), Task (inform stakeholders or request input?), Format (email, doc, slide), Constraints (length, level of detail).
03-09 · Quick Win: Summarizing With Claude
This is one of the easiest ways to start. Paste any text, meeting notes, article, email thread, and use:
Paste
Copy the text (meeting transcript, article, email thread)
Prompt
Use the template above, or customize it.
Refine
"Shorten to 2 sentences" / "Format as email" / "Translate for a non-technical audience"
03-10 · Exercise: Write Your First Real Prompt
Part 2 (5 min): Write a prompt using the 6-part framework: Role, Context, Task, Constraints, Format, Verify.
Part 3 (optional): Run your prompt. Review the output. What would you change?
Check-in: Which part felt most useful? What was hard about writing the prompt?
Your Project Folder
5 minutes of setup saves you hours of re-explaining yourself every session. This is the foundation of everything.
04-02 · Why Work in a Folder?
If you use Claude on the website (claude.ai), every conversation starts completely blank. Claude has no idea about your work, your clients, or your context.
- Every conversation starts blank
- Claude has no idea who you are
- You re-explain context every single time
- Nothing is saved or organized
- Like asking a stranger on the street
- Claude reads your files = instant context
- Claude writes and updates files = work saved
- Everything organized, nothing lost
- Context files live here permanently
- Like handing a dossier to a briefed teammate
04-03 · Setting Up Your Project Folder
Create the main folder
On Desktop or Documents, create: Claude Cowork
Create subfolders inside it
ABOUT ME, your context files
OUTPUTS. Claude saves all work here
TEMPLATES, reusable prompts you build over time
Download Claude desktop app
Go to claude.com/download. Install it. This unlocks Cowork Mode.
Open Cowork → New Task → Select folder
Claude is now connected to your workspace and can see all files inside it.
Select model: Opus 4.6 + Extended Thinking
Use the dropdown. Extended Thinking = Claude reasons step-by-step before answering.
Run this every time you start a new Cowork session:
04-04 · Exercise: Create Your Folder Now
- Created Claude Cowork folder on Desktop or Documents
- Created ABOUT ME subfolder inside it
- Created OUTPUTS subfolder inside it
- Created TEMPLATES subfolder inside it
- Downloaded Claude desktop app from claude.com/download
- Opened Cowork Mode, selected the Claude Cowork folder
The Files That Make
Claude Actually Yours
Write these once. Use them forever. This is the difference between "generic AI output" and "this sounds exactly like my work."
05-02 · Why Context Files Matter
- "Who are you?" → Claude doesn't know
- "Who are you writing to?" → Claude doesn't know
- "What's your style?" → Claude guesses
- "What's happened before?" → Claude doesn't know
- Claude knows your role, company, audience
- Claude knows your writing style and preferences
- Claude knows your past decisions and guidelines
- Claude knows your common tasks and templates
05-03 · The 3 Essential Context Files
Who you are, your role, your communication style, your preferences. Like a personal briefing document.
Your writing guidelines: tone, formatting rules, words to use and avoid, style preferences.
Past decisions, common scenarios, rules of thumb. "If X happens, we do Y." Prevents repeated mistakes.
Start with one file. Add more as you discover what Claude keeps getting wrong about you.
05-04 · Template: about-me.md
Short, quick setup, functional profile
Long, deep voice & taste capture, full reference
05-06 · Template: writing-rules.md
05-07 · Template: decision-rules.md
05-08 · Template: anti-ai.md
05-09 · What Is claude.md? Special file
claude.md is a special file Claude reads automatically when it enters your project folder. Think of it as "global instructions", things you want Claude to know every single session, without being asked.
- Project-level context (the big picture)
- Key conventions and rules
- Links to your other context files
- Starting instructions for every session
- Task-specific details (those go in your prompt)
- Sensitive information (no secrets here)
- One-time instructions
05-10 · How Context Files Grow Over Time
| Timeline | What to do |
|---|---|
| Week 1 | Start small: about-me.md + claude.md + anti-ai.md. Nothing else needed. |
| Month 1 | Add a rule whenever Claude makes the same mistake twice. Create a template for any recurring task. |
| Month 3 | Remove outdated content. Merge related files. Share templates with your team. |
05-11 · Before vs. After: The Context Difference
Scenario: "Write a response to a client who's concerned about timeline delays."
→ Generic. Vague. Sounds like every other agency email.
→ Specific. On-brand. Personal. Actionable.
05-12 · Exercise: Write Your First Context File
- Wrote about-me.md, ran the interview prompt or wrote manually from the template
- Created claude.md, standing instructions Claude follows every session
- Created anti-ai.md, your list of writing pet peeves (see Section 6)
- All files saved in the ABOUT ME/ folder
- Tested with "read my folder" prompt. Claude confirmed it understands
Claude Becomes a
Real Teammate
Cowork Mode is where Claude transforms from a chatbot into a collaborator. The single biggest productivity jump you'll experience.
06-02 · What Changes in Cowork Mode
- Claude can only talk to you
- No access to your files
- No memory of past conversations
- Everything must be typed manually
- Claude sees your entire project folder
- Reads any file you point it to
- Creates and edits files directly
- Works WITH you, not just responding to you
06-03 · How Cowork Mode Works
Opens and reads any file in your project folder. Instantly knows your context, drafts, and reference materials, no copy-paste needed.
Creates new files and edits existing ones. Writes drafts, updates documents, organizes your work directly to disk.
Reasons through problems step by step. Uses AskUserQuestion to ask YOU clarifying questions before executing.
Searches through your files for specific information. No more manual Ctrl+F through long documents.
06-04 · The "Read Before Write" Principle
A simple rule: before asking Claude to write or change anything, first ask it to read and understand. Prevents hallucinations and wrong assumptions.
Read
"Read this document and tell me what it's about."
Write
"Now update the timeline section based on the new dates."
Verify
"Show me exactly what you changed."
06-05 · What Claude Can (and Cannot) Do in Cowork
- Read and analyze your files
- Write and edit documents
- Create new files from templates
- Search through your project folder
- Make suggestions and recommendations
- Track changes across versions
- Access files outside your selected folder
- Remember things from other sessions (without Projects)
- Make decisions for you, you're always in charge
- Send emails or messages on your behalf
- Browse the internet without a web tool
- Execute code without your approval
06-06 · First Safe Tasks to Try in Cowork
- Read your context files. "Read my about-me.md and tell me what you understand about me."
- Create a document. "Create a meeting-notes-template.md in my project folder."
- Edit a document. "Add these three bullet points to the project notes."
- Ask about your project. "What files do I have in my project folder?"
- Draft something. "Draft a status update email using the info in my project notes."
- Review your work. "Read this document and suggest concrete improvements."
06-07 · When to Use Chat vs When to Use Cowork
- Quick questions and brainstorming
- Drafting short content (social posts, quick emails)
- Learning about a new topic
- Getting a second opinion on something
- Working on an actual document or project
- Reading and analyzing your files
- Making edits to existing work
- Any task that needs your context files
06-08 · Cowork: Recurring Example
Let's see how Cowork changes our meeting-to-email scenario:
"Read my meeting-notes.md in the ABOUT ME folder."
→ Claude reads your notes instantly. No copy-paste needed.
"Using my writing-rules.md and about-me.md, draft a meeting summary."
→ Claude combines your context files + notes. Creates a formatted document.
"Draft the follow-up email to Sarah and save it as acme-followup.md."
→ Claude writes the email. Saves it to your OUTPUTS folder. You review and send.
Total time: ~5 minutes. Everything saved to your project folder. Zero copy-paste.
06-09 · Cowork Projects: Persistent Memory
The old Cowork forgot everything between sessions. Cowork Projects fixes this, persistent memory, custom instructions, task history.
Claude remembers what it did inside this project. "Build on last week's report", it knows what that was.
Your rules and tone baked in. Every task inside this project follows them automatically.
Every run stored. Go back and see what Claude did, when, and the exact output produced.
Create your first Cowork Project: Open Claude desktop → Cowork tab → Projects → + → "Use an existing folder" → Select your Claude Cowork folder → Add custom instructions (paste from claude.md)
06-10 · Cowork Mode Check-In
• What felt easy about Cowork Mode?
• What felt unfamiliar?
• What task would you try first in your real work?
Key takeaway: Cowork Mode isn't a different tool, it's the same Claude with more abilities. You already know how to prompt. Now Claude can also read, write, and organize.
06-10 · Your Full Setup. Done ✓
From Trying It
to Using It Daily
The habit is simple. The discipline is the hard part. Here's exactly how to build it, and what to do when things go wrong.
07-02 · The Iteration Loop
Write a clear prompt using your framework. Context + Task + Format at minimum.
Read Claude's output critically. Actually read it. Don't accept the first draft without reading it.
Tell Claude what to change. Don't rewrite it yourself, tell Claude to fix it.
2-3 rounds of refinement is normal. First draft is always a starting point, never a finished product.
07-03 · When Claude Gets It Wrong (And Why)
| What went wrong | Why it happened | The fix |
|---|---|---|
| Generic, vague output | Not enough context | Add background, audience, specific situation |
| Wrong assumptions | Missing decision rules | Add a rule to your context files |
| Outdated information | Claude's knowledge has a cutoff date | Provide current info directly in your prompt |
| Invented facts (hallucination) | Claude filled gaps with patterns | Always verify facts, names, numbers independently |
| Misinterpreted task | Instructions were ambiguous | Be more specific; give a concrete example |
07-04 · Troubleshooting: Prompt Issues
| Problem | Likely cause | Fix |
|---|---|---|
| Output is generic | No context | Add background, audience, specific situation |
| Output too long / too short | No length constraint | Specify word count or "2-3 sentences max" |
| Wrong tone | No tone guidance | Give examples + describe the voice explicitly |
| Missing key information | Task too vague | Break into specific sub-tasks |
| Off-topic tangents | No boundaries set | Add "Don't include X" or "Focus only on Y" |
07-05 · Troubleshooting: Context Issues
| Problem | Likely cause | Fix |
|---|---|---|
| Claude ignores context files | Files not in project folder | Check files are in ABOUT ME/ folder |
| Claude forgot earlier instruction | Context window too full | Start fresh conversation with key context |
| Output doesn't match your voice | No writing rules or anti-ai.md | Create or update your writing rules file |
| Claude says "they" for your company | Missing rule in context files | Add "Always say 'we', never 'they'" to claude.md |
| Claude doesn't know your client | No client context | Add client notes to your context files |
07-06 · Troubleshooting: Mode & Model Issues
| Problem | Likely cause | Fix |
|---|---|---|
| Response too slow | Using Opus for simple tasks | Switch to Sonnet for everyday work |
| Response lacks depth | Using Haiku for complex tasks | Switch to Opus + Extended Thinking |
| Can't create files | In Chat mode, not Cowork | Switch to Cowork Mode |
| Claude can't see your files | Wrong folder selected | Check you opened the right project folder |
| Claude says "I can't do that" | Capability not available in this mode | Check if task needs Cowork mode |
07-07 · When to Start a New Conversation
- Claude keeps repeating itself
- You switched to a completely different topic
- Conversation is very long (100+ messages)
- Claude's responses are getting worse over time
- You're still iterating on the same task
- Good context is already established
- The conversation is still productive
07-08 · Troubleshooting Scenarios
You asked Claude to "write a proposal" and got back something that sounds like every other agency. What's the most likely fix?
Claude keeps referring to your company as "they" instead of "we." How do you fix that permanently?
You're 50 messages into a client project conversation and now need to draft something for a completely different client. What do you do?
Answers: (1) Add context: about-me.md + company voice + a real example. (2) Add rule to claude.md and anti-ai.md permanently. (3) Start a completely fresh conversation, different client = different context.
07-09 · Building the Habit: Your 5 Key Habits
- Write prompts with context: Role, Context, Task, Format, every single time
- Read and verify everything Claude produces before using or sending it
- Iterate, first draft is never final, expect and plan for 2-3 rounds
- Use Cowork Mode for any project work or file creation
- Start fresh conversations when switching tasks or topics
Claude is Brilliant.
You're Responsible.
Claude makes you faster. Your judgment makes you good. This distinction is the most important thing in this entire training.
08-02 · Trust, But Always Verify
Claude is fluent, confident, and sometimes wrong. Verification isn't optional, it's the whole game.
"Write a migration script."
→ Runs without review. The script had a destructive operation that wasn't flagged. Disaster.
"Write a migration script. Before you finish, check: Does it handle rollbacks? Does it preserve existing data? Flag any destructive operations."
→ Reviewed. Caught two issues. Safe.
What to verify: Facts & numbers, factual correctness, security issues, appropriateness of tone, assumptions Claude made.
08-03 · Verification Checklist
Before you use anything Claude produces:
- Facts. Are names, dates, numbers, and statistics correct? Claude can and does hallucinate.
- Tone. Does this sound like you and your company? Or does it sound like generic AI?
- Assumptions. Did Claude assume something about your situation that isn't actually true?
- Completeness. Does it cover everything you asked for? Is anything missing?
- Accuracy. Is the content actually correct? Or does it merely sound correct?
- Safety. Does it contain anything sensitive, speculative, or inappropriate for the audience?
08-04 · What NOT to Share With AI
- Passwords, API keys, or credentials
- Personal private data (passport numbers, financial details)
- Confidential business secrets or anything under NDA
- Proprietary code or data without company approval
- Meeting notes (without sensitive data)
- Draft documents and public information
- General project context
- Writing samples and templates
08-05 · Your Judgment Is What Matters
The most important takeaway of this entire training:
Claude is a tool, it doesn't replace your judgment.
- You are responsible for everything you produce using AI
- You make the final call on what's right and what's ready
- You catch the mistakes. You spot the gaps. You decide when it's done.
- You choose what to share and what to keep private.
Claude makes you faster. Your judgment makes you good.
You Made It.
Now Start.
You now know more about using AI effectively than most people who use it every day. The rest is practice.
09-01 · What You've Learned
| Part | Key takeaway |
|---|---|
| 1 · Foundations | AI is pattern-matching, not magic. Tokens, context windows, the delegation mindset. |
| 2 · The Landscape | Claude is 6 tools. Chat + Cowork cover 95% of daily needs. |
| 3 · Prompting | Role, Context, Task, Constraints, Format, Verify. Context is the most important part. |
| 4 · Your Folder | Claude Cowork / ABOUT ME / OUTPUTS / TEMPLATES. 5 minutes of setup, saves hours. |
| 5 · Context Files | about-me.md + claude.md + anti-ai.md. Write once, use forever. |
| 6 · Cowork Mode | Claude reads, writes, edits files. Read before write. Projects = persistent memory. |
| 7 · The Habit | Ask → Review → Refine → Repeat. Fix the prompt, not the model. |
| 8 · Trust & Judgment | Verify everything. Never share sensitive data. Your judgment is irreplaceable. |
09-02 · Your First Real Task
Open Claude in Cowork Mode on your project folder
Pick a real task from today's work
Email, summary, status update, document draft, anything you'd normally spend 20+ minutes on.
Write a prompt using the framework
Role, Context, Task, Constraints, Format.
Review Claude's output critically
Make one round of refinements, then use it
09-03 · Next Steps & Resources
Use Claude for at least one real task every day for the next two weeks. The habit compounds fast.
Every time Claude gets something wrong, add a rule to anti-ai.md or claude.md immediately.
Settings → Connectors. Add Slack, Google Drive, Notion. Claude reads your actual tools.
Share useful prompts and context files. A shared template library benefits everyone.
Resources:
- claude.ai. Chat mode for quick tasks
- claude.com/download. Desktop app for Cowork Mode
- docs.claude.ai. Official documentation and prompt engineering guide
- Your team lead. For questions and support
09-04 · Congratulations
You Made It
Congratulations on completing the training.
You now know more about using AI effectively than most people who use it every day. The rest is practice. Every prompt you write, every output you review, every context file you create, that's where the skill builds.
You've got everything you need to start. The only thing left is to begin.

Prompt Patterns
Once you're comfortable with the basics, these patterns unlock more precise and powerful outputs.
A-01 · Model Selection Quick Guide
| Model | Best for | Speed | Think of it as |
|---|---|---|---|
| Haiku 4.5 | Quick tasks, drafts, simple Q&A | Fastest | Your quick assistant |
| Sonnet 4.6 | Everyday work, writing, analysis | Fast | Your main collaborator |
| Opus 4.6 | Complex analysis, strategy, hard problems | Thoughtful | Your senior advisor |
| + Extended Thinking | Math, logic, strategy. "show your work" tasks | Slower but better | Available on Opus |
A-02 · Extended Thinking: When Claude "Thinks"
Extended Thinking mode makes Claude reason step-by-step before answering. You see the reasoning process. Better for complex problems.
Complex analysis, strategic decisions, debugging, anything where "show your work" matters.
Simple drafts, quick questions, routine tasks, regular mode is faster and equally good.
Visible reasoning process. Makes hidden assumptions easier to catch. More reliable on hard problems.
A-03 · Prompt Pattern: Role Prompting
Give Claude a specific persona to adopt. Fundamentally changes the lens of every response.
A-04 · Prompt Pattern: Chain of Thought
Ask Claude to reason step by step before answering. Makes hidden assumptions visible. Easier to catch errors.
A-05 · Prompt Pattern: Persona + Constraint
Combine role with specific hard limits for precise, bounded output.
A-06 · Prompt Pattern: Format Constraint
Tell Claude exactly how to structure its response. Eliminates guesswork entirely.
A-07 · More Context File Tips
- Keep files focused. One topic per file. Don't dump everything into about-me.md.
- Use plain markdown (.md). Claude reads it cleanly. No Word docs in the context folder.
- Set a quarterly reminder. Review and update context files every 3 months.
- Add real examples. A "good email / bad email" example is worth more than any description.
- Share with your team. A shared template library benefits everyone and compounds over time.
- Trim when it gets long. If about-me.md exceeds 2,000 words, ask Claude to help you condense it.
A-08 · Building a Template Library
Find a task you do at least weekly
Meeting recap, client email, status update, project brief, weekly report.
Write the best prompt you can for it
Use all 6 parts of the framework.
Replace specific content with [PLACEHOLDERS]
Remove names, dates, and details.
Save to TEMPLATES/ folder
Name it clearly: "meeting-recap.md", "client-email.md"
A-09 · Bonus: What Are Skills?
Skills are packaged prompt workflows that Claude can run automatically, like "super templates" for complex recurring tasks.
A SKILL.md file in a folder that defines what Claude does, when to use it, and the step-by-step process.
Once you're comfortable with prompting and Cowork. Skills are for tasks you run 2-3x per week with a consistent structure.
Meeting recap generation, client email drafting, project status updates, research summarization.
A-10 · What Makes a Good Skill
- Specific. Does one thing well, not everything vaguely
- Reusable. You use it at least once a week
- Structured. Clear steps, not a wall of text
- Tested. You've run it 3+ times and refined it
- Shared. Your team can use it too
Practice & Quick Reference
Extra exercises, cheat sheets, and everything you need in one place.
A-12 · More Troubleshooting Tips
| Symptom | Check | Fix |
|---|---|---|
| Claude is repetitive | Context window too full | Start fresh conversation |
| Claude ignores instructions | Prompt is too long | Put key instructions first and last (Claude pays most attention to beginning and end) |
| Claude is too formal | No tone guidance | Add "Write like a human, not a corporation" to your prompt or anti-ai.md |
| Claude says "I don't have enough info" | Missing context | Add more specific details about the situation |
| Output is too long | No length constraint | Add "Keep this under [X words/sentences]" |
A-13 · Extra Practice: Meeting Recap
You attended a 30-minute project check-in. Key points: Budget approved for Q3 campaign. Timeline moved up 2 weeks (deadline: June 15). Client requested weekly check-ins. Two new stakeholders added: Sarah (Finance) and Mike (Creative).
Example answer: Role: You're a project coordinator attending a Q3 campaign check-in. Context: [paste notes]. Task: Write a full meeting recap. Format: Summary (3 bullets) → Decisions (numbered list with owners) → Action items (due dates) → Next steps. Constraints: Under 300 words. Flag any action items that don't have a clear owner.
A-14 · Extra Practice: Client Communication
A client emailed asking why a deliverable is late. The delay is due to a third-party vendor who provided incomplete assets. The relationship is 2 years old. The client has been patient but this is the second delay this quarter.
• Acknowledges the delay honestly
• Explains the cause without sounding like an excuse
• Provides a new timeline with some buffer
• Rebuilds confidence
• Uses your company's professional-but-warm voice (reference your writing-rules.md)
A-15 · Extra Practice: Research & Summary
You have a 20-page industry report. You need to: (1) extract the 5 most important findings, (2) explain each in 1-2 sentences, (3) note implications for your company, (4) suggest 3 potential actions.

A-20 · What's Next for AI
The AI landscape is moving fast. Here's what's coming:
- Better integration with tools you already use
- AI agents that run multi-step workflows
- Improved accuracy, fewer hallucinations
- More specialized models for specific industries
- Your judgment is still what matters most
- Context and clarity will always improve output
- Verification will always be necessary
- The human in the loop is irreplaceable
TL;DR: Just Tell Me What to Do
5 minutes. Claude Cowork/ with ABOUT ME/, OUTPUTS/, TEMPLATES/. This is the foundation. Without it, every session starts from zero.
→ Do this first, before anything else
Use the interview prompt in this training. Tell Claude who you are, how you work, and what you expect. Write once, use forever. This is what makes output sound like you.
→ Create both files this week
Role · Context · Task · Constraints · Format · Verify. At minimum: Context + Task + Format. The 30 seconds you spend setting context saves 30 minutes of editing.
→ Bookmark the prompt framework (section A-18)
Two-pass reading: facts first, tone second. Assume Claude is confidently wrong until you prove otherwise. Never send AI output without review. Ever.
→ Use the verification checklist (section 8-03)
First draft is never final. Tell Claude what to fix - don't rewrite it yourself. 2-3 rounds of refinement is normal, not failure. Quality is in the iteration.
→ Expect refinement, budget for it
New task = new conversation. Different client = different conversation. When responses get worse, you've filled the context window. Start fresh and bring key context forward.
→ Fresh conversations are not failure
The One Rule That Trumps Everything
Claude drafts. You decide.
AI removes the friction of getting words on the page. It does not remove the responsibility of deciding whether those words are right. Your judgment is the bottleneck - not the speed of generation.
- One-shot prompts, no context, accept first output
- Copy/paste between tools
- Treat Claude like a search engine
- Rich context + verification + iteration
- Work in Cowork Mode with project folder
- Treat Claude like a collaborator
Browse the Web from Your Terminal
Claude can search the web, fetch documentation, and read live pages - all without leaving your editor. No more context-switching to a browser tab.
06b-01 · Web Search
Claude can search the web for current information, documentation, code examples, and more. The results are brought directly into your conversation context.
Ask Claude to search the web: "Find the latest React 19 release notes." Claude returns summarized results with source links.
"Search for the Prisma migration API reference." Claude finds the relevant docs and incorporates them into your working context.
Combine search with your project context: "Search for best practices in Next.js 15 server components, then review my page.tsx against them."
06b-02 · Fetch & Browse Pages
Beyond search, Claude can read the full content of any public URL. This is useful for API documentation, blog posts, error pages, or any live web content.
- API documentation pages for specific library versions
- GitHub repos, issues, and pull requests
- Technical blog posts and tutorials
- Package registry pages (npm, PyPI, crates.io)
- Your own deployed apps for debugging
- Requires a public URL (no authenticated/internal pages)
- Some JavaScript-rendered pages may not load fully
- Large pages are summarized, not returned verbatim
- Rate limits may apply for aggressive fetching
06b-03 · When to Browse vs. Search
Knowing which tool to use saves time. Search is for discovery; fetch is for depth. Use search when you don't know the exact source, and fetch when you have a specific page in mind.
You need to find something: "Search for recent Tailwind CSS v4 changes." You don't know the exact URL or source. Let Claude find it.
You have a specific URL: "Fetch https://example.com/docs/api and tell me how to use the createClient function." You want deep analysis of one page.
Search first to find the right page, then fetch it: "Search for the Prisma migration guide - then fetch the top result and help me write my schema."
Connect Claude to Your Tools
MCP (Model Context Protocol) is how Claude connects to your database, APIs, file storage, and internal tools. It turns Claude from a standalone chat into an integrated part of your development ecosystem.
06c-01 · What is MCP?
MCP is an open standard that lets AI models interact with external systems through a unified protocol. Think of it as "USB-C for AI" - one standard way to connect any tool to any AI model.
Every MCP server exposes the same interface: tools, resources, and prompts. Claude discovers what's available when the connection starts - no manual configuration per tool.
Claude asks for permission before using any connected tool. You approve each action individually. Connections are not backdoors - they're gates you control.
MCP servers exist for databases (Postgres, SQLite), cloud storage (Google Drive, Dropbox), project management (Jira, Linear), communication (Slack), and more. Anyone can build one.
06c-02 · Setting Up Connections
Connections are configured per-project in your Claude settings. You define the MCP server endpoint, and Claude handles the rest.
- Find or install an MCP server for your tool (npm packages, Docker containers, or custom scripts)
- Add the server configuration to your project's CLAUDE.md or settings
- Claude discovers available tools when the session starts
- Use natural language: "Query the database for recent orders" or "Create a Jira ticket"
- Database: MCP server connects to Postgres, exposes read-only query tools
- File storage: MCP server connects to Google Drive, provides file search and read tools
- Project management: MCP server wraps the Jira API, exposes create/update/search tools
- Each server defines its own tool set - Claude adapts automatically
06c-03 · Real-World Use Cases
Connectors bridge Claude to specific services. Here are two practical examples of how you'd use them in daily work.
Find the cheapest flight from New York to Tokyo, no red-eye flights. The connector queries Booking.com's inventory and filters by your preferences - price, duration, departure time. Claude presents the top options in a clean summary without you opening a single browser tab.
Unsubscribe me from all promotional emails I received this week. The connector scans your inbox, identifies marketing and spam messages, and processes unsubscribe requests - or drafts them for your review before sending.
06c-04 · Security & Best Practices
Connections are powerful - and with power comes responsibility. Claude has built-in safeguards, but you should understand how they work.
Every MCP tool call requires your approval. Claude shows you exactly what it's about to do: which tool, what parameters. You approve or deny each time.
Configure MCP servers with the minimum access needed. Use read-only database users, scoped API tokens, and sandboxed environments where possible.
All MCP interactions are logged in your session history. You can review what Claude accessed and when. This makes troubleshooting and security review straightforward.
Skills: Expertise on Tap
Skills are pre-configured expert capabilities you invoke with /skill commands. They bundle specialized prompts, tools, and context into one command - like having a specialist join your conversation on demand.
06d-01 · Built-in Skills
Claude ships with a growing library of built-in skills for common development tasks. Each one is optimized for a specific job.
/code-review analyzes recent changes for quality, security, and maintainability. It checks for common issues and generates structured reports with severity levels.
/security-review scans for vulnerabilities: hardcoded secrets, injection risks, unsafe patterns. Flags issues by severity with remediation steps.
/docs-lookup fetches library documentation on demand. "How do I use Prisma transactions?" - it searches docs and returns relevant examples.
/build-error-resolver diagnoses build failures. Paste your error message and it walks through the stack trace, identifies root cause, and suggests fixes.
/tdd-guide enforces test-driven development: write the test first, implement, verify. Keeps you honest about test coverage.
/refactor-cleaner identifies dead code, unused imports, and opportunities to simplify. "Clean up this module" - it analyzes and removes what's not needed.
06d-02 · Creating Custom Skills
Teams and individuals can create their own skills for recurring workflows. This is where skills become force multipliers - you encode your team's best practices once and share them.
- A specific, repeatable task (deployment checklist, onboarding review)
- Clear success criteria (what "done" looks like)
- Access to the tools it needs (database, linting, etc.)
- A well-defined scope (does one thing well)
- Start with a prompt: what would you tell a junior dev to do?
- Add tool access: what should the skill be able to run?
- Define output: what does the skill return? A report? A fix? An analysis?
- Test iteratively: run the skill, refine, repeat
06d-03 · When to Use Skills
Skills are best for tasks that follow a repeatable pattern. They're not meant for open-ended exploration - that's what regular conversation is for.
Running a code review before PR submission. Auditing for security issues. Checking test coverage. Formatting code to team standards. Diagnosing build errors.
Brainstorming architecture. Debugging a novel issue. Learning a new concept. Exploratory coding. Skills automate - they don't explore.
Use a skill as the starting point: run /code-review to check changes, then discuss findings in normal conversation. Let skills handle the structured work while you focus on judgment calls.
File Access: Your Project, Claude's Workspace
Claude operates directly on your file system. It reads, creates, and edits files within your project - always with your awareness and control. This is how Claude goes from conversation partner to active contributor.
06e-01 · Reading & Searching
Claude can read any file in your project and search across your entire codebase. This is how it understands your code before making changes.
Claude reads files to understand your code: "Show me the database schema file." It reads the content and can explain, analyze, or suggest changes to it.
"Find all places where we call the payment API." Claude greps your codebase, finds every reference, and presents them in context - no manual searching.
"How does the auth flow work?" Claude reads the relevant files (routes, middleware, handlers) and traces the full flow end-to-end, showing you how pieces connect.
06e-02 · Creating & Editing Files
This is where the real work happens. Claude can create new files, edit existing ones, and restructure code - all with your explicit approval.
- You ask for a change: "Add input validation to the signup form"
- Claude reads the relevant files to understand current code
- Claude proposes changes as a diff - you see exactly what changed
- You approve or request adjustments before the edit is applied
- Claude suggests changes; you control what gets applied
- Every edit shows a diff before application - review it
- Claude can create new files, modify existing ones, or delete unused code
- Edits are atomic: you approve or reject each one individually
06e-03 · Real-World Example: Tax Receipts
Here's a complete file access workflow that combines reading, creating, and analysis - all in one natural language request.
- "I need to file my taxes. I have receipt photos on my desktop. Create a folder called Tax-2025, dump all the receipt images into it, then output an Excel spreadsheet with a full breakdown of each expense including date, vendor, amount, and category."
- Reads the image files from your desktop (using OCR to extract text from receipt photos)
- Creates the Tax-2025 folder and organizes all receipts inside
- Extracts structured data: dates, vendor names, totals, line items
- Generates an Excel (.xlsx) file with columns for date, vendor, amount, category, and file name
- Presents a summary of total expenses by category for your review
06e-04 · Permission Model
Claude has a layered permission system that lets you control exactly what it can access. Understanding this system helps you work confidently.
Claude only operates within your selected project folder. It cannot access files outside this boundary without explicit permission. Your system files are off-limits.
Reading files is typically automatic. Writing requires approval. You can configure Claude to ask for permission on reads too, or to auto-approve certain write patterns.
Files like .env, credentials, and private keys are never read without explicit request. Claude knows to avoid accessing secrets unless you specifically ask it to.
Scheduled Tasks: Let Claude Watch for You
Claude Code can run tasks on a schedule - reminders, recurring checks, and automated monitoring. Set up once, and Claude keeps you informed without constant manual checking.
06f-01 · One-Shot Reminders
The simplest scheduled task: a single notification at a specific time. Use these for time-sensitive callbacks during your workday.
"Remind me to check the deploy at 2pm." Claude schedules a single notification. When the time comes, you get a message in your active session - no separate calendar or alarm needed.
"Remind me in 30 minutes to review the PR comments." Claude sets a timer relative to now. Useful for not getting lost in a task while something else is cooking.
"Tell me when the build finishes." Claude monitors a process and notifies you when it completes. You can switch to other work without polling for results.
06f-02 · Recurring Jobs
For ongoing monitoring and regular checks, set up recurring tasks that fire on a schedule. These run automatically until you cancel them.
- Health checks: "Check staging server every morning at 9am"
- Standup prep: "At 9:15am, summarize yesterday's changes"
- Deploy monitoring: "Every hour during deployment, check if the rollout progressed"
- Cleanup: "Every Friday, list stale branches that can be deleted"
- Recurring jobs auto-expire after 7 days to prevent abandoned tasks
- Jobs are session-bound - they stop when your Claude session ends
- You can cancel any job at any time with a simple command
- Jobs survive across context-window resets within a session
06f-03 · Task Management During Sessions
You can view, cancel, and manage all your active tasks at any time. This gives you full visibility into what's running and when.
Ask "What tasks are running?" to see all scheduled jobs, their next fire time, and their status. Clean up tasks you no longer need.
"Cancel the health check reminder" stops a specific task. "Cancel all tasks" clears the entire schedule. Tasks are removed immediately.
"Change the health check to every 2 hours instead of 1." Cancel and recreate with the updated schedule. Tasks are cheap - don't hesitate to adjust.
PDF to Markdown: Save Tokens, Read Better
Claude reads Markdown efficiently. PDFs - especially scanned ones - consume excessive tokens and often produce garbled output. Converting PDFs to Markdown before uploading reduces token usage by 50-80% and dramatically improves output quality.
The Problem: PDFs Eat Your Token Budget
When you batch-upload PDFs to Claude, you'll notice your token budget exhausted very quickly. That's because Claude must process raw PDF data - layout information, fonts, sometimes embedded images - all of which count toward your token limit. A 20-page PDF that uses 40,000 tokens in its original format might use only 8,000 tokens when converted to Markdown.
The fix is simple: Convert PDFs to Markdown before uploading. Markdown is pure text with lightweight formatting - Claude reads it directly, and you get 3-5x more content per token.
C-01 · The Skill: What It Does
This skill reads PDF files through Cowork Mode, extracts their content, and saves clean Markdown versions. After the first conversion, you work with the Markdown files - the PDF is processed once and the tokens are spent once.
Place your PDFs in a Cowork-accessible folder (e.g., ~/Documents/pdf-input/).
Run the skill: /pdf-to-md. Claude reads each PDF and converts it to clean Markdown.
Claude saves the .md files side by side with the originals. Upload those to any future conversation.
C-02 · Install the Skill
Create a file called pdf-to-md.md in your project's skills folder (e.g., ~/.claude/skills/pdf-to-md.md or ./skills/pdf-to-md.md). Paste this content:
C-03 · How to Use It
Once installed, invoke the skill anytime:
Just type /pdf-to-md in your conversation. Claude will ask where your PDFs are, read them, and save clean Markdown versions.
Same command: /pdf-to-md. Claude Code can also run marker-pdf for better accuracy on complex documents (see C-04).
