## Prerequisites

- [x] Sprint 51 Complete (Composio Phase 2)
- [x] All 3,434+ tests passing
- [x] Gateway already available (Sprint 44)
- [x] CTO sign-off received

---

## Key Deliverables

### 4 Non-Negotiable Invariants (Task 1)

Added to CLAUDE.md:

1. **THIN CLIENT PATTERN**: Commands are wrappers calling `./endiorbot.mjs`
2. **STDIN JSON FOR HOOKS**: Hooks receive JSON via stdin, parse with jq
3. **ENDIORBOT SOUL = GOVERNANCE, CLAUDE CODE = EXECUTION**: Business logic in EndiorBot
4. **DEFAULT MODEL = SONNET**: Model directive in all command files

### /project:gate Command (Task 2)

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

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

### /project:consult Command (Task 3)

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

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

### PreToolUse Hook - Secret Guard (Task 4)

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

# Blocks writes to sensitive files:
# - .env*
# - *secret*
# - *token*
# - *.pem
# - *.key
# - *credential*
# - *password*

# Warns on potential breaking changes without ADR
```

**Patterns Blocked**: 7 sensitive file patterns
**ADR Warning**: For src/providers/* and src/gateway/* changes

### PostToolUse Hook - Vibecoding-lite (Task 5)

```bash
#!/bin/bash
# Post-tool-use hook: Quality checks
# Runs lint on touched packages
# Non-blocking (exit 0 always)

# Features:
# - Lint on touched package
# - Vibecoding-lite for src/ changes
# - tsc + eslint checks
```

### settings.json Configuration (Task 6)

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