Lightweight alternative to /gsd-map-codebase that spawns a single mapper agent for one focus area instead of four parallel agents. Supports --focus flag with 5 options: tech, arch, quality, concerns, and tech+arch (default). Checks for existing documents and prompts before overwriting.

Lightweight codebase assessment. Spawns a single gsd-codebase-mapper agent for one focus area,

producing targeted documents in `.planning/codebase/`.

## Focus-to-Document Mapping
|
|
|
|
| Focus | Documents Produced |
|
|
|-------|-------------------|
|
|
| `tech` | STACK.md, INTEGRATIONS.md |
|
|
| `arch` | ARCHITECTURE.md, STRUCTURE.md |
|
|
| `quality` | CONVENTIONS.md, TESTING.md |
|
|
| `concerns` | CONCERNS.md |
|
|
| `tech+arch` | STACK.md, INTEGRATIONS.md, ARCHITECTURE.md, STRUCTURE.md |
|
|
|
|
## Step 1: Parse arguments and resolve focus
|
|
|
|
Parse the user's input for `--focus <area>`. Default to `tech+arch` if not specified.
|
|
|
|
Validate that the focus is one of: `tech`, `arch`, `quality`, `concerns`, `tech+arch`.
|
|
|
|
If invalid:
|
|
```
|
|
Unknown focus area: "{input}". Valid options: tech, arch, quality, concerns, tech+arch
|
|
```
|
|
Exit.
|
|
|
|
## Step 2: Check for existing documents
|
|
|
|
```bash
|
|
INIT=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" init map-codebase 2>/dev/null || echo "{}")
|
|
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
|
|
```
|
|
|
|
Look up which documents would be produced for the selected focus (from the mapping table above).
|
|
|
|
For each target document, check if it already exists in `.planning/codebase/`:
|
|
```bash
|
|
ls -la .planning/codebase/{DOCUMENT}.md 2>/dev/null
|
|
```
|
|
|
|
If any exist, show their modification dates and ask:
|
|
```
|
|
Existing documents found:
|
|
- STACK.md (modified 2026-04-03)
|
|
- INTEGRATIONS.md (modified 2026-04-01)
|
|
|
|
Overwrite with fresh scan? [y/N]
|
|
```
|
|
|
|
If user says no, exit.
|
|
|
|
## Step 3: Create output directory
|
|
|
|
```bash
|
|
mkdir -p .planning/codebase
|
|
```
|
|
|
|
## Step 4: Spawn mapper agent
|
|
|
|
Spawn a single `gsd-codebase-mapper` agent with the selected focus area:
|
|
|
|
```
|
|
Task(
|
|
prompt="Scan this codebase with focus: {focus}. Write results to .planning/codebase/. Produce only: {document_list}",
|
|
subagent_type="gsd-codebase-mapper",
|
|
model="{resolved_model}"
|
|
)
|
|
```
|
|
|
|
## Step 5: Report
|
|
|
|
```
|
|
## Scan Complete
|
|
|
|
**Focus:** {focus}
|
|
**Documents produced:**
|
|
{list of documents written with line counts}
|
|
|
|
Use `/gsd-map-codebase` for a comprehensive 4-area parallel scan.
|
|
```
|
|
