<h1>What is Claude Code?</h1>
<p>Claude Code isn't just Claude. It's Claude (the model) wrapped in a <strong>harness</strong> with a set of <strong>tools</strong> &mdash; and that wrapper is what turns a chatbot into an agent.</p>
<div style="display: grid; grid-template-columns: 1fr 1fr 1fr; gap: 24px; margin: 32px 0;">

<h4 style="font-size: 1rem; color: #7b1fa2; text-transform: none; letter-spacing: 0; margin-bottom: 10px;"><strong>Model</strong></h4>
<p style="font-size: 0.95rem; color: #555; margin: 0;">The brain. Knows everything up to its training cutoff. Doesn&rsquo;t know today&rsquo;s date, can&rsquo;t read your files, can&rsquo;t search the web.</p>
</div>
<div class="col-card" style="border-left: 4px solid #2196f3; text-align: center;">

<h4 style="font-size: 1rem; color: #1565c0; text-transform: none; letter-spacing: 0; margin-bottom: 10px;"><strong>Harness</strong></h4>
<p style="font-size: 0.95rem; color: #555; margin: 0;">The body around the brain. Manages memory, permissions, how long conversations run, and how the brain talks to tools.</p>
</div>
<div class="col-card" style="border-left: 4px solid #4caf50; text-align: center;">
<div style="font-size: 2.2rem; margin-bottom: 12px;">&#x1F91C;</div>
<h4 style="font-size: 1rem; color: #2e7d32; text-transform: none; letter-spacing: 0; margin-bottom: 10px;"><strong>Tools</strong></h4>
<p style="font-size: 0.95rem; color: #555; margin: 0;">The hands. Read files, edit code, search the web, run commands, spawn helper agents.</p>
</div>
</div>
<p style="text-align: center; font-size: 1.3rem; font-weight: 600; color: #1a1a1a; margin: 24px 0;"><strong>Claude Code = Model + Harness + Tools</strong></p>
<div class="trigger-box">
<h4>Why This Matters</h4>
<p>Ask a bare model &ldquo;what&rsquo;s the capital of Pakistan?&rdquo; &mdash; it answers from training data. Ask it &ldquo;what time is it in Karachi right now?&rdquo; &mdash; it can&rsquo;t know. That second question needs a <strong>tool</strong>, exposed through a <strong>harness</strong>. That&rsquo;s the difference Claude Code makes &mdash; and the rest of this session teaches you how to configure it.</p>

<h4>The Key Field for This Workshop</h4>
<p>The <code>skills:</code> field is what makes the weather-agent special. It preloads <code>weather-fetcher</code> directly into the agent's brain at startup &mdash; before the agent has received a single instruction. The agent doesn't need to be told how to fetch weather; it already knows.</p>

<h4>Think of it like this</h4>
<p>When someone joins your team, they have a role (agent), but they also go through specific training modules &mdash; how to use the CRM, how to write a proposal, how to run a standup. Each training module is a <strong>skill</strong>.</p>

<h1>When to Turn Something Into a Skill</h1>
<div class="info-box">
<h4>Tip from Boris Cherny (creator of Claude Code) &mdash; Feb 1, 2026</h4>
<p>"If you do something <strong>more than once a day</strong>, turn it into a skill."</p>
</div>
<p>The rule is simple: anything you're explaining to Claude over and over is a skill waiting to be written down. The weather reporter's skills are a perfect example:</p>
<div class="use-cases">
<div class="use-case-item">
<span class="use-case-icon">&#x1F321;&#xFE0F;</span>

<p>Skills are how <strong>repetition becomes reliability</strong>. Write it down once, and Claude does it the same way forever &mdash; or until you update the skill.</p>

<!-- Slide 17: Why Separate Agents and Skills? -->
<div class="slide" data-slide="18">
<h1>Why Separate Agents and Skills?</h1>
<div class="two-col">
<div>
<h3>Agent = The Person</h3>
<p>The <code>weather-agent</code> is the person with the job title <strong>"Weather Reporter"</strong>.</p>
<p>It defines the <em>role</em> and <em>behavior</em>: use Open-Meteo, return temperature, track history in memory.</p>
</div>
<div>
<h3>Skill = The Training</h3>
<p>The <code>weather-fetcher</code> skill is the specific training on <strong>how</strong> to fetch weather data.</p>
<p>It contains exact instructions:</p>
<ul class="feature-list">
<li>Call this specific API URL</li>
<li>Extract <code>current.temperature_2m</code> from the response</li>
<li>Return value + unit in this exact format</li>
</ul>
</div>
</div>
<div class="how-to-trigger" style="margin-top: 24px;">
<h4>The Power</h4>
<p><strong>One agent can have multiple skills</strong>, and <strong>one skill can be used by multiple agents</strong>. Skills are reusable building blocks. Agents are the people who use them.</p>

<h1>&#x1F9E0; Context &mdash; The Reporter's Brain</h1>
<p class="section-desc">Now that you've met the reporter and know their skills, let's understand what they can actually hold in mind at once. Every agent &mdash; including the weather reporter &mdash; gets its own fresh brain.</p>
</div>
<!-- Slide 21: Claude's Brain -->
<div class="slide" data-slide="22">
<h1>Claude's Brain</h1>
<div class="analogy-box">
<h4>Think of it like this</h4>
<p>Imagine Claude has a <strong>brain</strong> that holds everything it's aware of right now &mdash; your question, every file it's opened, every tool result, every word it's said back to you. If a thought isn't in the brain, Claude can't use it. Simple as that.</p>

<p>When the <code>weather-agent</code> is dispatched, it gets its own fresh brain &mdash; and <code>weather-fetcher</code> is pinned into it at startup via the <code>skills:</code> field. Everything you give Claude in a conversation lands in its brain:</p>
<div class="use-cases">
<div class="use-case-item">
<span class="use-case-icon">&#x1F4AC;</span>

<div class="warning-box">
<h4>Two Things Every Non-Engineer Should Know</h4>
<p><strong>1. The brain is finite.</strong> It can hold about 1 million tokens &mdash; roughly 750,000 words, or a short novel. Big, but not infinite. <strong>2. The brain empties at the end of every chat.</strong> When you start a new conversation, Claude remembers <em>nothing</em> from the last one unless you tell it again.</p>

<!-- Slide 22: What Loads at Session Start -->

<p>The more stuff crammed into Claude's brain, the harder it is to focus on what matters. This is called <strong>context rot</strong> &mdash; performance drops as the brain gets crowded.</p>

<h4>Tip from Thariq (Anthropic) &mdash; Apr 16, 2026</h4>
<p>"Every turn is a branching point." After Claude finishes a response, you don't have to just keep typing. You have <strong>five options</strong> &mdash; and four of them exist to keep the brain clear.</p>

<div class="slide" data-slide="31">
<h1>How CLAUDE.md Loads</h1>
<p>Claude Code uses two mechanisms to find CLAUDE.md files:</p>
<div class="two-col">
<div class="col-card" style="border-left: 4px solid #2196f3;">
<h4>Ancestor Loading (UP)</h4>
<p>At startup, Claude walks <strong>upward</strong> from your current directory and loads every CLAUDE.md it finds.</p>
<p style="margin-top: 12px;"><strong>Always loaded immediately.</strong></p>
</div>
<div class="col-card" style="border-left: 4px solid #ff9800;">
<h4>Descendant Loading (DOWN)</h4>
<p>CLAUDE.md files in subdirectories below you are loaded <strong>lazily</strong> &mdash; only when Claude reads files in those folders.</p>
<p style="margin-top: 12px;"><strong>Loaded on demand.</strong></p>
</div>
</div>
<div class="code-block"><span class="comment"># Example: running `claude` from /myapp</span>
/myapp/
<span class="claude-file">CLAUDE.md</span> <span class="comment"># Loaded at startup (current dir)</span>
frontend/
<span class="key">CLAUDE.md</span> <span class="comment"># Loaded when you touch frontend/ files</span>
backend/
<span class="key">CLAUDE.md</span> <span class="comment"># Loaded when you touch backend/ files</span></div>
<div class="info-box">
<h4>Rules Directory</h4>
<p>For topic-specific instructions, use <code>.claude/rules/*.md</code>. Each rule file can target specific file patterns using <code># Glob: pattern</code> at the top &mdash; they only load when Claude works with matching files.</p>

<div class="slide" data-slide="33">
<h1>Commands &mdash; The Entry Point</h1>
<div class="analogy-box">
<h4>Think of it like this</h4>
<p>If agents are employees and skills are their training, a <strong>command</strong> is the manager's playbook &mdash; "when someone asks for a weather report, first ask them Celsius or Fahrenheit, then dispatch the weather team, then create the visual."</p>
</div>
<p>You've already seen built-in commands in this presentation:</p>

<p>Commands are markdown files too. If you can write a recipe, you can write a command.</p>
<div class="how-to-trigger">
<h4>The File</h4>
<p>Create <code>.claude/commands/&lt;your-command-name&gt;.md</code>. As soon as it's saved, <code>/&lt;your-command-name&gt;</code> appears in Claude Code's slash menu.</p>

<h4>Think of it like this</h4>
<p>A command is like <strong>a button on a coffee machine</strong>. One press, the machine grinds, brews, foams, pours. You don't think about the steps &mdash; you just want espresso. Slash commands are buttons you've labelled yourself.</p>

1. Ask the user: Celsius or Fahrenheit?
2. Use the <span class="key">weather-agent</span> to fetch Dubai's temperature
3. Use the <span class="key">weather-svg-creator</span> skill to create an SVG card
4. Show the user the result</div>

<p>Commands are how you turn a multi-step prompt into a single keystroke that anyone on your team can run.</p>

<!-- Slide 36: Two Ways Skills Are Used -->
<div class="slide" data-slide="37">
<h1>Two Ways Skills Are Used</h1>
<p>The weather workflow demonstrates both skill patterns in a single flow:</p>
<div class="two-col">
<div class="col-card" style="border-left: 4px solid #9c27b0;">
<h4>Pattern 1: Agent Skill (Preloaded)</h4>
<p><code>weather-fetcher</code> is listed in the agent's <code>skills:</code> field.</p>
<p style="margin-top: 12px;">Its full content is <strong>injected into the agent's context</strong> at startup. The agent reads it like a reference manual.</p>
<div class="code-block" style="font-size: 0.8rem;"><span class="comment"># In weather-agent.md</span>
<span class="key">skills</span>:
- <span class="string">weather-fetcher</span></div>
</div>
<div class="col-card" style="border-left: 4px solid #2196f3;">
<h4>Pattern 2: Direct Invocation</h4>
<p><code>weather-svg-creator</code> is called directly by the command via the Skill tool.</p>
<p style="margin-top: 12px;">It runs <strong>independently</strong> in the command's context, not inside any agent.</p>
<div class="code-block" style="font-size: 0.8rem;"><span class="comment"># In the command prompt</span>
<span class="cmd">Skill</span>(<span class="key">skill</span>: <span class="string">"weather-svg-creator"</span>)</div>

</div>
<!-- Slide 37: How to Wire Your Own Workflow -->
<div class="slide" data-slide="38">
<h1>How to Wire Your Own Workflow</h1>
<p>A workflow isn't a separate file type. It <em>emerges</em> when one command calls agents and skills in sequence.</p>
<div class="how-to-trigger">
<h4>The Recipe</h4>
<p>One <strong>command</strong> at the top. One <strong>agent</strong> with a <strong>skill</strong> preloaded for fetching. One <strong>skill</strong> at the end for output. Wire them in the command file.</p>
</div>
<div class="hiring-steps">
<div class="hiring-step level-1">
<span class="hiring-step-number">1</span>
<div class="hiring-step-content">
<strong>Write the command (entry point)</strong>
<span><code>.claude/commands/weather-orchestrator.md</code> &mdash; the playbook the user types.</span>
</div>
</div>
<div class="hiring-step level-2">
<span class="hiring-step-number">2</span>
<div class="hiring-step-content">
<strong>Write the agent and its preloaded skill</strong>
<span><code>.claude/agents/weather-agent.md</code> with <code>skills: [weather-fetcher]</code> in its config &mdash; the specialist + their training.</span>
</div>
</div>
<div class="hiring-step level-3">
<span class="hiring-step-number">3</span>
<div class="hiring-step-content">
<strong>Write the output skill</strong>
<span><code>.claude/skills/weather-svg-creator/SKILL.md</code> &mdash; invoked directly by the command after the agent returns.</span>
</div>
</div>
</div>
<div class="analogy-box">
<h4>Think of it like this</h4>
<p>The workflow is the <strong>relay race</strong>. The command is the starter pistol. The agent is runner one (fetches the data, hands the baton back). The skill is runner two (turns the data into a visual). You don't run the race &mdash; you just point and say "go."</p>

<div class="trigger-box">
<h4>Takeaway</h4>
<p>Every workflow you'll ever build follows this same shape: <strong>Command at the top, Agent + Skill in the middle, Skill at the end</strong>. Once you've wired one, the rest are variations on the theme.</p>
