# Plan Project Implementation
## Overview
The `overseer.plan_project` tool has been fully implemented with end-to-end functionality. It creates project structures, validates inputs, generates markdown files, and provides detailed feedback.
## Features
### 1. Input Validation
- Validates repository name is not empty
- Validates at least one phase is provided
- Validates phase names against available templates in `sentinel.yml`
- Provides clear error messages for invalid inputs
### 2. Repository Management
- Creates repository directory under `~/dev` (or configured base path)
- Handles both new and existing projects
- Preserves existing phases when adding new ones
### 3. Phase Creation
- Validates phase names against templates
- Skips duplicate phases gracefully
- Creates phase info with proper status tracking
- Generates detailed phase markdown files
### 4. File Generation
#### PHASES.md (Markdown Format)
- Project metadata (created, updated, total phases)
- List of all phases with status, description, and timestamps
- Human-readable markdown format
- Backward compatible with JSON format (auto-detects)
#### PHASE-*.md Files
- Phase name and status
- Description from template
- Checklist of steps (with checkboxes)
- List of expected artifacts
- Progress tracking section
- Creation timestamp
### 5. Error Handling
- Comprehensive try-catch blocks
- Detailed error messages
- Continues processing even if individual phases fail
- Returns partial success information
### 6. Response Format
The tool returns a detailed response object:
```typescript
{
success: boolean;
message: string;
phases_created: string[];
phases_skipped: string[];
errors: string[];
repo_path: string;
files_created: string[];
}
```
## Example Usage
```json
{
"repo_name": "my-new-project",
"phases": ["planning", "implementation", "testing"]
}
```
## Generated Files
### PHASES.md Example
```markdown
# Project Phases: my-new-project
This document tracks the phases of the project.

## Implementation Details
### Core Components
1. **PhaseManager.planProject()** - Main orchestration logic
- Input validation
- Template validation
- Phase creation
- File generation
2. **RepoHandler** - File operations
- `writePhasesIndex()` - Generates markdown PHASES.md
- `writePhaseFile()` - Creates individual phase files
- `readPhasesIndex()` - Parses both JSON and markdown formats
3. **ConfigLoader** - Configuration management
- Loads sentinel.yml
- Provides phase templates
- Validates against available templates
### Error Scenarios Handled
- Invalid repository name
- Empty phase list
- Invalid phase names (not in templates)
- Missing templates
- File system errors
- Duplicate phases
- Existing projects
### Success Criteria
- All valid phases created
- All files written successfully
- No errors in processing
- Proper status tracking initialized
## Next Steps
The tool is production-ready. Future enhancements could include:
- Git integration (auto-commit if configured)
- Phase dependencies
- Custom phase templates per project
- Phase ordering/sequencing
