Use when reviewing documentation quality, when establishing README and changelog standards, when preventing doc rot, when in-code comments duplicate code instead of explaining intent, or when subdirectories of a repo have no documentation entry point.

基于 SOC 职业分类
Use when implementing features or fixing bugs test-first, when user mentions "red-green-refactor", when test discipline is required for a specific task, when incremental-implementation needs TDD enforcement, or when a behavior change needs a failing test before any code is written.
Use when .forge/prd.md exists and the system needs a structural design before task breakdown, when modules will be implemented in parallel and need interface contracts to prevent integration failures, or when non-obvious technical decisions need to be recorded for future reference.
Use when .forge/prd.md and .forge/architecture.md exist and the work needs to be decomposed before implementation, when sizing tasks for a sprint, when mapping dependencies between modules, or when a critical path needs to be identified before parallel work begins.
Use when user wants to write a spec, create a PRD, or plan a new feature before implementation begins, when .forge/idea-brief.md exists and is ready to formalize, when requirements need to be captured before architecture or planning, or when a feature's scope and acceptance criteria need to be documented.
Use when creating a new forge-skill, editing an existing skill, when planning to contribute to forge-skills, when a session has produced a one-off prompt that should be promoted to a skill, or when verifying a skill works before deployment.
Use when checking if .forge/ artifacts are stale after a change to requirements, architecture, or any upstream artifact. Use before running /build, /review, or /ship to confirm the artifact chain is consistent. Use when the user says "is anything out of date" or "what needs to be regenerated".

Define the project's documentation contract — what gets documented, where it lives, how it stays current — before docs rot. Output is .forge/docs-policy.md: README standard per repo and subdirectory, in-code comment policy (WHY not WHAT), doc-rot prevention rules (dates, code links, generated docs), public-vs-internal doc split, and changelog discipline. Pairs with code-review-and-quality (review enforces the policy) and shipping-and-launch (CHANGELOG updated per release).
| Thought | Reality |
|---|---|
| "The code is self-documenting" | Code shows what, not why. Two months later the original author cannot reconstruct why. |
| "Docs get stale anyway, why bother" | Dated docs with code links rot slower than undated docs. The half-life of a comment near its code is years; far from its code, weeks. |
| "README is enough" | README without subdirectory docs creates a treasure hunt for every new contributor. |
| "We'll document before launch" | You won't. And if you do, the doc will be wrong because you'll write it from memory. |
| "Comments are noise" | Comments that explain WHY are signal. Comments that restate the code are noise. The fix is to write the right comments, not to delete all comments. |
| "Generated docs are good enough" | Generated docs answer "what does this function take" — not "when should I call it" or "what changes if I don't." |
// increment i by 1 next to i++In .forge/docs-policy.md, the README contract for every repo top-level:

One-sentence description.
## What this is
2-3 sentence description.
## Status
Stable / Beta / Experimental — and what that means for breaking changes.
## Quick start

## Where things live

## Contributing
How to propose a change. Link to CONTRIBUTING.md if it exists.

For every subdirectory with >5 files: a README that answers "what is in here, why is it here, who owns it."
The rule: explain WHY, not WHAT.
| Bad (WHAT) | Good (WHY) |
|---|---|
// increment i | // skip the sentinel row at index 0 |
// loop over users | // fan-out concurrency capped at 5 to respect upstream rate limit |
// returns null | // returns null when the user has been soft-deleted; callers must filter |

Refactors don't get entries unless they affect performance, security, or behavior. Updated in the PR that makes the change, not at release time.
