```

**Total**: 5 new files + 1 update

---

## Implementation Tasks

### Task 1: Update CLAUDE.md (1h)

**File**: `/CLAUDE.md`

**Changes**:
```markdown
# Add after "## Overview" section:

## 🚨 4 Non-Negotiable Invariants

\`\`\`
1. THIN CLIENT PATTERN
   Claude Code commands = wrappers that call ./endiorbot.mjs
   NO business logic in .md files
   Gate checks, vibecoding, multi-model → all in EndiorBot core

2. STDIN JSON FOR HOOKS
   Hooks receive JSON via stdin, NOT positional arguments
   Always parse with jq: cat /dev/stdin | jq -r '.tool_name'
   Test: echo '{"tool_name":"Edit","file_path":"test.ts"}' | ./hook.sh

3. ENDIORBOT SOUL = GOVERNANCE, CLAUDE CODE = EXECUTION
   EndiorBot SOUL decides WHAT to build (PM, requirements, gates)
   Claude Code executes HOW to build (Architect, Coder, Reviewer)
   No PM agent in Claude Code (prevents orchestration conflict)

4. DEFAULT MODEL = SONNET
   Opus only for explicit architecture decisions
   Commands use model: sonnet unless specified
   Budget guard: track /cost regularly
\`\`\`

## Claude Code Integration Examples

### Thin Client Pattern
\`\`\`bash
# Commands call EndiorBot core, no business logic in .md files
! ./endiorbot.mjs gate check G3
! ./endiorbot.mjs consult "Redis vs PostgreSQL for sessions?"
\`\`\`

### Hook stdin JSON Format
\`\`\`bash
# Hooks receive JSON via stdin
INPUT=$(cat /dev/stdin)
TOOL_NAME=$(echo "$INPUT" | jq -r '.tool_name // empty')
FILE_PATH=$(echo "$INPUT" | jq -r '.file_path // empty')
\`\`\`
```

**Test**:
```bash
# Verify invariants are documented
grep -q "THIN CLIENT PATTERN" CLAUDE.md && echo "✅ Invariants added"
```

---

### Task 2: Create `/project:gate` Command (1.5h)

**File**: `.claude/commands/gate.md`

**Content**:
```markdown
---
description: Check SDLC gate status and requirements
argument-hint: gate-id (G0, G0.1, G1, G2, G3, G4)
allowed-tools: ["Bash"]
model: sonnet
---

# Check SDLC Gate Status

**THIN CLIENT**: This command calls EndiorBot core. NO business logic here.

\`\`\`bash
! ./endiorbot.mjs gate check $ARGUMENTS
\`\`\`

The output includes:
- Gate ID and status (PASS/FAIL/PENDING)
- Checklist items (✅/❌)
- Evidence collected
- Vibecoding index
- Recommendation

All logic is in `src/sdlc/gates/gate-engine.ts` (SSOT).
```

**Test**:
```bash
# Test command exists and works
claude
> /project:gate G3
# Expected: Output from ./endiorbot.mjs gate check G3
# (May show "command not found" if gate subcommand not implemented yet - that's OK for Sprint 52)
```

**Acceptance Criteria**:
- [x] File created at `.claude/commands/gate.md`
- [x] YAML frontmatter correct (description, argument-hint, allowed-tools, model)
- [x] Content is thin client (only calls `./endiorbot.mjs`)
- [x] No business logic in `.md` file
- [x] Command appears in `/help` or tab completion

---

### Task 3: Create `/project:consult` Command (1.5h)

**File**: `.claude/commands/consult.md`

**Content**:
```markdown
---
description: Query multiple AI models for expert opinions
argument-hint: query or question
allowed-tools: ["Bash"]
model: sonnet
---

# Multi-Model Consultation

**THIN CLIENT**: Calls EndiorBot gateway for multi-model orchestration.

\`\`\`bash
! ./endiorbot.mjs consult "$ARGUMENTS"
\`\`\`

EndiorBot gateway will:
1. Classify task type (architecture/security/code_review/research)
2. Select expert panel (Claude + GPT + Gemini + Mistral)
3. Query models in parallel
4. Consolidate responses
5. Return consensus + disagreements + SDLC compliance

Output format:
- RECOMMENDATION: [summary]
- CONSENSUS: [agreements]
- CONCERNS: [disagreements]
- SDLC: [compliance status]

All orchestration logic in `src/agents/multi-model/` (SSOT).
```

**Test**:
```bash
# Test command exists and works
claude
> /project:consult "Should I use Redis or PostgreSQL for session storage?"
# Expected: Output from ./endiorbot.mjs consult
# (May show "command not found" if consult subcommand not implemented yet - that's OK for Sprint 52)
```

**Acceptance Criteria**:
- [x] File created at `.claude/commands/consult.md`
- [x] YAML frontmatter correct
- [x] Content is thin client (only calls `./endiorbot.mjs`)
- [x] Quotes around `$ARGUMENTS` for multi-word queries
- [x] Command appears in `/help` or tab completion

---

### Task 4: Create PreToolUse Hook (2h)

**File**: `.claude/hooks/pre-tool-use.sh`

**Content**:
```bash
#!/bin/bash
# Pre-tool-use hook: SDLC compliance + secret guard
# Input: JSON via stdin (NOT positional args)

# Read JSON from stdin
INPUT=$(cat /dev/stdin)

# Parse with jq
TOOL_NAME=$(echo "$INPUT" | jq -r '.tool_name // empty')
FILE_PATH=$(echo "$INPUT" | jq -r '.file_path // empty')

# Exit if required fields missing
[[ -z "$TOOL_NAME" ]] && exit 0
[[ -z "$FILE_PATH" ]] && exit 0

case $TOOL_NAME in
  "Write"|"Edit")
    # EXPANDED SECRET GUARD (P0 from Expert H)
    # Block writes to sensitive files
    if [[ $FILE_PATH =~ \.env ]] || \
       [[ $FILE_PATH =~ secret ]] || \
       [[ $FILE_PATH =~ token ]] || \
       [[ $FILE_PATH =~ \.pem$ ]] || \
       [[ $FILE_PATH =~ \.key$ ]] || \
       [[ $FILE_PATH =~ credential ]] || \
       [[ $FILE_PATH =~ password ]]; then
      echo "❌ BLOCKED: Cannot write to sensitive file: $FILE_PATH"
      echo "Reason: Secret/credential file detected"
      echo "Use secure environment variable management instead"
      exit 1
    fi

    # Warn on breaking changes without ADR
    if [[ $FILE_PATH == src/providers/* ]] || [[ $FILE_PATH == src/gateway/* ]]; then
      BASE_NAME=$(basename "$FILE_PATH" .ts)
      if ! ls docs/02-design/01-ADRs/ADR-*.md 2>/dev/null | grep -qi "$BASE_NAME"; then
        echo "⚠️  WARNING: Potential breaking change without ADR"
        echo "File: $FILE_PATH"
        echo "Consider creating ADR-XXX-${BASE_NAME}.md"
        echo ""
        echo "Continue? This is a warning, not a block."
      fi
    fi
    ;;
esac

exit 0  # Always allow (warnings only, no hard blocks except secrets)
```

**Make executable**:
```bash
chmod +x .claude/hooks/pre-tool-use.sh
```

**Test**:
```bash
# Test 1: Should BLOCK .env writes
echo '{"tool_name":"Edit","file_path":".env.local"}' | .claude/hooks/pre-tool-use.sh
# Expected: Exit code 1, error message

# Test 2: Should WARN on provider changes without ADR
echo '{"tool_name":"Edit","file_path":"src/providers/gemini/index.ts"}' | .claude/hooks/pre-tool-use.sh
# Expected: Exit code 0, warning message

# Test 3: Should PASS normal files
echo '{"tool_name":"Edit","file_path":"src/utils/helpers.ts"}' | .claude/hooks/pre-tool-use.sh
# Expected: Exit code 0, no output
```

**Acceptance Criteria**:
- [x] File created and executable
- [x] Stdin JSON parsing works (not `$1`, `$2`)
- [x] Blocks 7 secret patterns (`.env*`, `*secret*`, `*token*`, `*.pem`, `*.key`, `*credential*`, `*password*`)
- [x] Warns on `src/providers/*` and `src/gateway/*` without ADR
- [x] Exit code 0 for warnings, 1 for blocks
- [x] All 3 test cases pass

---

### Task 5: Create PostToolUse Hook (2h)

**File**: `.claude/hooks/post-tool-use.sh`

**Content**:
```bash
#!/bin/bash
# Post-tool-use hook: Auto-quality checks
# Input: JSON via stdin (NOT positional args)

# Read JSON from stdin
INPUT=$(cat /dev/stdin)

# Parse with jq
TOOL_NAME=$(echo "$INPUT" | jq -r '.tool_name // empty')
FILE_PATH=$(echo "$INPUT" | jq -r '.file_path // empty')

# Exit if required fields missing
[[ -z "$TOOL_NAME" ]] && exit 0
[[ -z "$FILE_PATH" ]] && exit 0

case $TOOL_NAME in
  "Edit"|"Write")
    # Lint on touched package (NOT auto-format to avoid loops)
    if [[ $FILE_PATH == src/* ]] || [[ $FILE_PATH == apps/* ]]; then
      PKG_DIR=$(dirname "$FILE_PATH")
      # Find nearest package.json
      while [[ "$PKG_DIR" != "." ]] && [[ ! -f "$PKG_DIR/package.json" ]]; do
        PKG_DIR=$(dirname "$PKG_DIR")
      done

      if [[ -f "$PKG_DIR/package.json" ]]; then
        echo "🔍 Linting: $PKG_DIR"
        (cd "$PKG_DIR" && pnpm lint --fix "$FILE_PATH" 2>/dev/null) || true
      fi
    fi

    # Vibecoding-lite check for src/ changes
    if [[ $FILE_PATH == src/* ]]; then
      echo "📊 Vibecoding-lite: $FILE_PATH"
      # Check: tsc pass? lint pass? test exists?
      pnpm tsc --noEmit --project tsconfig.json 2>&1 | grep -q "$FILE_PATH" && echo "⚠️  TypeScript errors"
    fi
    ;;
esac
```

**Make executable**:
```bash
chmod +x .claude/hooks/post-tool-use.sh
```

**Test**:
```bash
# Test: Should lint touched file
echo '{"tool_name":"Edit","file_path":"src/test.ts"}' | .claude/hooks/post-tool-use.sh
# Expected: Linting message, exit code 0

# Test: Should run vibecoding-lite on src/ files
echo '{"tool_name":"Write","file_path":"src/providers/test.ts"}' | .claude/hooks/post-tool-use.sh
# Expected: Vibecoding-lite message, tsc check
```

**Acceptance Criteria**:
- [x] File created and executable
- [x] Stdin JSON parsing works
- [x] Finds nearest `package.json` correctly
- [x] Runs `pnpm lint --fix` on touched file only (not whole project)
- [x] NO auto-format with prettier (avoids loops)
- [x] Vibecoding-lite runs tsc check
- [x] Exit code always 0 (non-blocking)

### Task 6: Configure Hooks in settings.json (30min)

**File**: `.claude/settings.json`

**Content**:
```json
{
  "hooks": {
    "preToolUse": {
      "enabled": true,
      "script": ".claude/hooks/pre-tool-use.sh"
    },
    "postToolUse": {
      "enabled": true,
      "script": ".claude/hooks/post-tool-use.sh"
    }
  }
}
```

**Test**:
```bash
# Test hook configuration is loaded
claude config list | grep -q "hooks" && echo "✅ Hooks configured"
```

**Acceptance Criteria**:
- [x] File created at `.claude/settings.json`

```markdown
# Sprint 52 Retrospective: Claude Code Integration - Minimal DevEx Pack

**Date**: YYYY-MM-DD
**Duration**: XX hours (Target: 10-12h)
**Participants**: @dev team, @pm, @ceo

---

## Sprint Goal
Implement Minimal DevEx Pack for Claude Code integration:
- 2 commands (/project:gate, /project:consult)
- 2 hooks (PreToolUse, PostToolUse)
- CLAUDE.md update with 4 invariants

---

## What Went Well ✅
- [List successes, e.g., "Hooks worked first try", "stdin JSON parsing clean"]
- [Quantify: "Completed in X hours vs 12h estimate"]
- [Technical wins: "Secret guard blocked all 7 patterns successfully"]

## What Didn't Go Well ❌
- [List blockers, e.g., "jq not installed initially", "Hook permissions issue"]
- [Time overruns: "Task 5 took 3h instead of 2h because..."]
- [Technical issues: "PostToolUse lint failed on monorepo packages"]

## Lessons Learned 📚
- [Process: "Should verify jq installed before starting"]
- [Technical: "chmod +x must be done before testing hooks"]
- [Documentation: "Test commands more explicit in guide"]

## Action Items for Sprint 52
- [ ] [Improvement 1, e.g., "Add jq check to prerequisites script"]
- [ ] [Improvement 2, e.g., "Create hook testing script"]
- [ ] [Carry-over 3, e.g., "Document common hook debugging steps"]
