### 7. Template Discovery

List available templates:

```
Available templates:
  project          - Project definition (PROJECT.md)
  requirements     - Requirements specification (REQUIREMENTS.md)
  roadmap          - Development roadmap (ROADMAP.md)
  state            - Project state (STATE.md)
  context          - Phase context (CONTEXT.md)
  summary          - Phase summary (SUMMARY.md) [3 variants]
  phase-prompt     - Phase plan (PLAN.md)
  ...
```

### 8. Template Variant Selection

Automatic variant selection based on context:

```javascript
function selectSummaryVariant(context) {
  if (context.isQuickTask) return 'summary-minimal';
  if (context.taskCount <= 3) return 'summary-minimal';
  if (context.taskCount <= 8) return 'summary-standard';
  return 'summary-complex';
}
```

## Tool Use Instructions

### Loading and Filling a Template
1. Use `Glob` to locate the template file in `templates/`
2. Use `Read` to load the template content
3. Replace all `{{VARIABLE}}` placeholders with provided values
4. Process conditional blocks (`{{#if}}...{{/if}}`, `{{#unless}}...{{/unless}}`)
5. Add frontmatter if specified
6. Use `Write` to save the filled template to the target path

### Batch Generation
1. Accept list of template-to-target mappings
2. Load each template, fill variables with shared + per-file data
3. Write all files, collecting results
4. Return list of generated files

### Template Discovery
1. Use `Glob` to find all `.md` and `.json` files in `templates/`
2. Read first line of each to extract template name/purpose
3. Return formatted list

## Process Integration

- `new-project.js` - Batch generate PROJECT.md, REQUIREMENTS.md, ROADMAP.md, STATE.md
- `discuss-phase.js` - Generate CONTEXT.md from context template
- `plan-phase.js` - Generate PLAN.md files from phase-prompt template
- `verify-work.js` - Generate UAT.md from uat template
- `quick.js` - Generate plan and summary using minimal variants
- `debug.js` - Generate debug session file from debug template
- `complete-milestone.js` - Generate milestone archive from milestone-archive template
- `add-tests.js` - Generate test plan structure
- `research-phase.js` - Generate RESEARCH.md from research template
- `map-codebase.js` - Batch generate 7 codebase analysis documents

## Output Format

```json
{
  "operation": "fill|batch|discover",
  "status": "success|error",
  "template": "project",
  "variant": "standard",
  "targetPath": ".planning/PROJECT.md",
  "variablesFilled": 12,
  "conditionalsProcessed": 3,
  "generatedFiles": [
    ".planning/PROJECT.md",
    ".planning/REQUIREMENTS.md"
  ]
}
```

## Configuration

| Setting | Default | Description |
|---------|---------|-------------|
| `templatesDir` | `templates/` | Directory containing template files |
| `summaryVariant` | `standard` | Default summary variant |
| `injectFrontmatter` | `true` | Auto-add frontmatter to generated files |
| `variableDelimiter` | `{{...}}` | Variable placeholder syntax |

## Error Handling

| Error | Cause | Resolution |
|-------|-------|------------|
| `Template not found` | Template name does not match any file | List available templates, suggest closest match |
| `Unfilled variable` | Variable not provided in data | Use empty string or placeholder marker |
| `Target path exists` | File already at target location | Prompt for overwrite/append/skip |
| `Invalid conditional` | Malformed if/unless block | Fix template syntax |
| `Batch partial failure` | Some files in batch failed | Report which succeeded and which failed |

## Constraints

- Templates must be idempotent (filling same template with same data produces same output)
- Never modify template source files; only read them
- Generated files must be valid markdown (or JSON for config.json)
- Variable names must be uppercase with underscores only
- Conditional blocks must be properly nested and closed
- Batch operations are all-or-nothing within a single process call
