    "Query Patterns": "### User Asks: \"What do I do in RED phase?\"\n\n**Response:**\n```\n**RED Phase**: Write a failing test first\n\n**Core rule**: NO production code until you have a failing test\n\n**Process**:\n1. Identify simplest behavior to test\n2. Write test describing expected behavior\n3. Run test - verify it fails\n4. Only then move to GREEN phase\n\n**Example**:\n```typescript\n// RED: Test failing\nit(\"should reject negative payments\", () => {\n  const result = processPayment({ amount: -100 });\n  expect(result.success).toBe(false);\n});\n// Run test: ❌ FAILS (processPayment doesn't exist yet)\n```\n\n**Full guidelines**: ~/.claude/docs/workflow.md (lines 3-22)\n```\n\n### User Asks: \"Should I abstract this duplicate code?\"\n\n**Response (without loading full docs):**\n```\n**Decision Framework**: Semantic vs Structural\n\nAsk these questions:\n1. **Semantic**: Do these represent the SAME concept?\n2. **Evolution**: If one changes, should others change?\n3. **Comprehension**: Is the relationship obvious?\n\n**If YES to all** → Safe to abstract\n**If NO to any** → Keep separate\n\n**Example - DON'T abstract**:\n```typescript\nvalidatePaymentAmount(amount) // Payment limits (fraud rules)\nvalidateTransferAmount(amount) // Transfer limits (account rules)\n// Different concepts, different evolution paths\n```\n\n**Example - DO abstract**:\n```typescript\nformatUserName(first, last)\nformatCustomerName(first, last)\n// Same concept: \"display a person's name\"\n```\n\n**Full guidelines**: ~/.claude/docs/workflow.md (lines 259-328)\n```\n\n### User Asks: \"What's the refactoring checklist?\"\n\n**Response:**\n```\n**Refactoring Checklist**\n\nBefore refactoring:\n- [ ] Tests currently passing (green state)\n- [ ] Current code is committed\n- [ ] Refactoring adds clear value\n- [ ] External APIs stay unchanged\n\nDuring refactoring:\n- [ ] All tests continue passing\n- [ ] No test modifications needed\n\nAfter refactoring:\n- [ ] Tests still pass without changes\n- [ ] Code more readable than before\n- [ ] Commit refactoring separately\n\n**Priority levels**:\n- 🔴 Critical: Fix before commit (mutations, knowledge duplication)\n- ⚠️ High Value: Should fix (unclear names, magic numbers)\n- 💡 Nice: Consider later (minor improvements)\n- ✅ Skip: Already clean\n\n**Full guidelines**: ~/.claude/docs/workflow.md (lines 177-245)\n```",

    "Purpose": "Avoid context window bloat by:\n1. Indexing guideline locations\n2. Fetching only relevant sections\n3. Providing concise answers\n4. Linking to full docs when needed",
    "Response Strategy": "1. **Assess question scope**: Can I answer without full doc load?\n2. **Check index**: Do I have the relevant section mapped?\n3. **Retrieve targeted**: Fetch only needed lines\n4. **Provide concise answer**: With examples\n5. **Link to full docs**: For deep dive\n\n**Key principle**: Provide 80% of value with 20% of context usage.",
    "Targeted Retrieval": "sed -n \"${LINES}p\" \"$FILE\"\n```",
    "Commands Available": "- `Read` - Extract specific sections from docs\n- `Grep` - Search for patterns in guidelines"
