# Phase 4 Implementation Summary
## Overview
Phase 4: Phase Engine Tools has been successfully implemented. All phase execution and QA tools are now fully functional with real logic.
## Example Tool Responses
### 1. `overseer.run_phase`
**Input:**
```json
{
"repo_root": "/Volumes/projects/Overseerer-mcp",
"phase_id": "01",
"aggression_level": "normal"
}
```
**Output:**
```json
{
"success": true,
"message": "Phase 01 execution completed. 3 tasks complete, 2 pending.",
"phase_id": "01",
"completed_tasks": [
{
"task": "README.md",
"type": "deliverable",
"evidence": "File exists: README.md"
},
{
"task": "Project structure is in place",
"type": "done_criterion",
"evidence": "Directory exists: src/"
},
{

## Key Implementation Details
### 1. `run_phase` Execution Engine
- **Task Parsing**: Extracts deliverables and done_criteria from PHASE-XX.md markdown
- **Completion Checking**: Verifies file/directory existence for each task
- **Stub Creation**: Creates placeholder files based on `aggression_level`:
- `bossmode`: Aggressively creates all missing files
- `normal`: Creates files but is more conservative
- `conservative`: Only checks, doesn't create
- **Checklist Updates**: Automatically updates checkboxes in PHASE-XX.md
- **Status Tracking**: Updates phase status to "in_progress" when execution starts
### 2. `advance_phase` Validation Engine
- **Completeness Validation**: Checks all deliverables and done_criteria are:
- Marked complete in checklist
- Actually exist/verified in repository
- **Phase Locking**: Marks phase as "locked" (completed) when all items verified
- **Completion Summary**: Adds summary section to PHASE-XX.md
- **Next Phase Activation**: Automatically activates next phase
- **Missing Items Report**: Returns detailed list of incomplete items
### 3. QA Helpers
#### `lint_repo`
- **Language Detection**: Uses RepoAnalyzer to detect languages
- **Command Generation**: Recommends linting commands based on sentinel.yml
- **Fix Support**: Provides fix commands when `fix: true`
- **Extensible**: Easy to add support for more languages
#### `sync_docs`
- **Format Validation**: Ensures consistent markdown formatting
- **Section Verification**: Checks for required sections in phase files
- **Auto-Repair**: Creates missing sections and files
- **Dry Run**: Preview changes without applying
#### `check_compliance`
- **Structure Validation**: Checks directories and files against conventions
- **Phase Structure**: Validates PHASE-XX.md has required sections
- **Naming Conventions**: Verifies repository naming follows conventions
- **Strict Mode**: Option to require all checks pass
## Aggression Levels
The `aggression_level` parameter in `run_phase` controls how aggressively the tool creates files:
- **`bossmode`**: Creates all missing files immediately, even if they're just stubs
- **`normal`**: Creates files but is more selective, may leave some for manual creation
- **`conservative`**: Only checks completion, never creates files
## Phase Status Lifecycle
```
pending → in_progress → locked (completed)
↓
(advance_phase validates)
↓
(if complete → locked)
↓
(next phase → in_progress)
```

✅ All tools handle errors gracefully
## Next Steps
Phase 5: Implement config + conventions + IDE integration tools (env_map, generate_ci, secrets_template).
