<h1>Claude Flow</h1>
<p>
A structured workflow for AI-assisted coding: <strong>Research → Plan → Implement</strong>.
</p>
<h2>Setup</h2>
<p>Export your Anthropic API key:</p>
<pre><code>export ANTHROPIC_API_KEY=your-key-here</code></pre>
<p>Get one at <a href="https://platform.claude.com" target="_blank" rel="noopener">platform.claude.com</a></p>
<h2>Getting Started</h2>
<ol>
<li><strong>Add a project</strong> — Select a codebase folder</li>
<li><strong>Create a session</strong> — Start a new task</li>
<li><strong>Describe your work</strong> — Tell Claude what you want to build</li>
</ol>
<h2>Workflow</h2>
<p><strong>Research:</strong> Claude analyzes your codebase and writes findings to <code>research.md</code>. Add notes like <code>// REVIEW: check this</code> — click <strong>Review</strong> when done.</p>
<p><strong>Plan:</strong> Claude drafts an implementation plan in <code>plan.md</code> with code snippets and a TODO list. Iterate the same way.</p>
<p><strong>Implement:</strong> Claude executes the plan, marking tasks complete as it goes.</p>
<p className="onboarding-tip">Iterate on research and plan docs as long as you want. Click <strong>Submit</strong> when happy to move to the next phase.</p>
