### Roadmap Evolution

- Phase 5 added: Subagent Codebase Analysis
|
||||
- Phase 5 gaps found: Need gsd-indexer subagent for Steps 2-3
|
||||
- Phase 5 gap closure: Plans 05-03, 05-04 created for indexer agent and integration
|
||||
|
||||
### Blockers/Concerns
|
||||
|
||||
- `.planning/` is gitignored in GSD repo - intel files created but not committed (expected for project-local data)
|
||||
- **RESOLVED:** Phase 5 context bottleneck addressed with gsd-indexer agent (05-03 complete, 05-04 pending)

# Phase 05 Plan 03: gsd-indexer Agent Definition Summary
|
||||
|
||||
**One-liner:** Subagent definition for file indexing that extracts exports/imports using validated regex patterns and writes index.json directly to disk.
|
||||
|
||||
## What Was Built
|
||||
|
||||
Created `agents/gsd-indexer.md` following the `gsd-entity-generator.md` pattern:
|
||||
|
||||
**Agent structure:**
|
||||
- Frontmatter with name, description, tools (Read, Write, Bash), color
|
||||
- Role section explaining spawn context from `/gsd:analyze-codebase`
|
||||
- `<why_this_matters>` section explaining index consumers (convention detection, entity generation, PostToolUse hook)
|
||||
- 4-step process: parse_input, process_each_file, write_index, return_statistics
|
||||
|
||||
**Regex patterns (exact match with analyze-codebase Step 3):**
|
||||
|
||||
Export patterns:
|
||||
| Pattern | Regex | Purpose |
|
||||
|---------|-------|---------|
|
||||
| Named exports | `export\s*\{([^}]+)\}` | `export { a, b }` |
|
||||
| Declaration | `export\s+(?:const\|let\|var\|function\*?\|async\s+function\|class)\s+(\w+)` | `export const foo` |
|
||||
| Default | `export\s+default\s+(?:function\s*\*?\s*\|class\s+)?(\w+)?` | `export default` |
|
||||
| CommonJS object | `module\.exports\s*=\s*\{([^}]+)\}` | `module.exports = { }` |
|
||||
| CommonJS single | `module\.exports\s*=\s*(\w+)\s*[;\n]` | `module.exports = X` |
|
||||
| TypeScript | `export\s+(?:type\|interface)\s+(\w+)` | `export type/interface` |
|
||||
|
||||
Import patterns:
|
||||
| Pattern | Regex | Purpose |
|
||||
|---------|-------|---------|
|
||||
| ES6 | `import\s+(?:\{[^}]*\}\|\*\s+as\s+\w+\|\w+)\s+from\s+['"]([^'"]+)['"]` | `import X from 'y'` |
|
||||
| Side-effect | `import\s+['"]([^'"]+)['"]` | `import 'styles.css'` |
|
||||
| CommonJS | `require\s*\(\s*['"]([^'"]+)['"]\s*\)` | `require('x')` |
|
||||
|
||||
**Index schema (matches Step 5):**
|
||||
```javascript
|
||||
{
|
||||
version: 1,
|
||||
updated: Date.now(),
|
||||
files: {
|
||||
"/absolute/path": {
|
||||
exports: [],
|
||||
imports: [],
|
||||
indexed: Date.now()
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Critical rules:**
|
||||
- Write index.json directly (never return contents)
|
||||
- Use exact regex patterns from Step 3
|
||||
- Absolute paths as keys for O(1) lookup
|
||||
- Handle read errors gracefully (log, continue)
|
||||
- Return statistics only (~10 lines)
|
||||
|
||||
## Tasks Completed
|
||||
|
||||
| Task | Name | Commit | Key Files |
|
||||
|------|------|--------|-----------|
|
||||
| 1 | Create gsd-indexer agent definition | 5d03e14 | agents/gsd-indexer.md |
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed exactly as written.
|
||||
|
||||
## Decisions Made
|
||||
|
||||
1. **Absolute path keys**
|
||||
- Continues existing index.json schema decision from 01-01
|
||||
- Enables O(1) lookup for any file path
|
||||
- Consistent with PostToolUse hook expectations
|
||||
|
||||
## Verification Results
|
||||
|
||||
- [x] File exists at `agents/gsd-indexer.md`
|
||||
- [x] Frontmatter valid YAML (name, description, tools, color)
|
||||
- [x] Role section explains subagent purpose (spawned by analyze-codebase)
|
||||
- [x] Process has 4 steps: parse, process, write, return
|
||||
- [x] Export regex patterns match Step 3 exactly (6 patterns)
|
||||
- [x] Import regex patterns match Step 3 exactly (3 patterns)
|
||||
- [x] Index schema matches Step 5 format (version, updated, files)
|
||||
- [x] Critical rules section matches gsd-entity-generator style
|
||||
- [x] Returns statistics only (not index contents)
|
||||
|
||||
## Next Phase Readiness
|
||||
|
||||
**Prerequisites for 05-04:**
|
||||
- [x] gsd-indexer.md exists
|
||||
- [x] Agent follows expected patterns (direct write, stats return)
|
||||
- [x] Regex patterns validated against analyze-codebase Step 3
|
||||
- [x] Index schema matches existing expectations
|
||||
|
||||
**Ready for:** Integration into `/gsd:analyze-codebase` command Steps 2-3 (Plan 05-04)
