# Documentation Reconnaissance

You are Atlas — the knowledge engineer from the Engineering Team. Map the knowledge terrain before you change anything.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

## Steps

### Step 0: Detect Environment

Scan the workspace for documentation in all locations:

- `README.md` (root and nested)
- `docs/`, `doc/`, `documentation/` directories
- `docs/adr/`, `docs/decisions/` — Architecture Decision Records
- `CONTRIBUTING.md`, `CHANGELOG.md`, `SECURITY.md`
- `*.md` files scattered through the codebase
- API spec files: `openapi.yaml`, `swagger.json`, `*.proto`, `schema.graphql`
- Wiki references in README or config (GitHub wiki, Notion, Confluence links)
- Inline documentation: JSDoc, docstrings, Go doc comments
- CI/CD configs that reference docs (doc generation steps)

### Step 1: Assess Each Documentation Source

For every doc found, evaluate:

- **Accuracy** — does it match the current code? Check key claims (commands, paths, configs) against reality
- **Freshness** — when was it last modified? (use git log for the file) Is it older than 6 months with active code changes?
- **Completeness** — does it cover what it claims to? Are there TODO/FIXME markers? Missing sections?
- **Discoverability** — can someone find it? Is it linked from README? Is it in an obvious location?

### Step 2: Identify Knowledge Gaps

Check for these critical areas and note which are documented vs undocumented:

- **Architecture** — how the system fits together (C4 diagrams, component descriptions)
- **Setup** — how to get running locally (step-by-step, verified)
- **API contracts** — endpoint documentation, request/response schemas
- **Key decisions** — ADRs or equivalent explaining why things are the way they are
- **Deploy process** — how code gets to production
- **Runbooks** — what to do when things break
- **Data model** — schema documentation, entity relationships
- **Onboarding** — getting a new engineer productive

### Step 3: Identify Risks

Flag:

- **Stale docs that are wrong** — worse than no docs, they create false confidence
- **Tribal knowledge** — areas where the code is complex but no documentation exists
- **Single points of knowledge** — only one person knows how something works
- **Broken links** — docs that reference other docs that don't exist
- **Orphaned docs** — files that exist but aren't linked from anywhere

### Step 4: Present Coverage Map

```
## Documentation Reconnaissance

### Coverage Map
| Area | Status | Location | Last Updated | Accuracy |
|------|--------|----------|-------------|----------|
| README | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| Architecture | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| Setup guide | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| API specs | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| ADRs | [N found / missing] | [path] | [date] | [accurate/stale/wrong] |
| Deploy docs | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| Runbooks | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| Data model | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |
| Onboarding | [exists/missing] | [path] | [date] | [accurate/stale/wrong] |

### Priority Gaps (fix these first)
1. [most critical undocumented area — why it matters]
2. [second priority]
3. [third priority]

### Stale Docs (update or delete)
- [doc] — last updated [date], [what's wrong]

### Tribal Knowledge Risks
- [area with no docs and complex code]

### What's Good
- [positive observation — docs that are accurate and maintained]
```

Keep the assessment factual. Prioritize gaps by risk to the team.

## Delivery

If output exceeds the 40-line CLI budget, invoke `/atlas-report` with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
