# repository-context-map

## Registry Trigger

**Use when**

- repository context map before planning discovers source of truth candidate owner change surface conventions and source generated boundary
- plan before repository inspection wrong placement missing call graph no repo map unfamiliar codebase registry profile and build artifacts skill authoring

**Do not use when**

- no task-local repository context map decision is required
- candidate owner and change surface are known and only consumer test contract or generated impact proof remains; use `repository-impact-inspection`

## Skill Role

Discover the minimum pre-plan repository context that identifies source of truth, candidate owner, change surface, conventions, generated boundaries, and remaining unknowns. Bounded impact proof remains outside this phase.

## High-Value Rules

- Before planning, inspect only enough source, registry, generated-boundary, and convention evidence to identify the source of truth, candidate owner, and change surface.
- Once a candidate owner and change surface are known, hand consumer, test, contract, configuration, documentation, and generated-impact proof to `repository-impact-inspection`.
- Mark unknown ownership or uninspected boundaries as unknown with a next investigation owner; unknown is not safe.
- Separate source authoring content from generated built content and installed artifacts.
- Use bounded repository searches and direct reads as evidence.
- Classify claims as `FACT`, `INFERENCE`, `ASSUMPTION`, or `OPEN QUESTION`.
- Do not treat the context map as completion evidence.

## Anti-Patterns

- A repository map is not a broad inventory. It is the smallest evidence set that makes the plan reviewable.
- Generated outputs are impact surfaces, not automatically sources of truth.
- Tests, docs, and context freshness are part of the map because stale evidence and stale reader guidance cause false completion.
- Stale graph, missing graph edge, or graph/source mismatch requires graph refresh or explicit direct-source fallback.

## Stop Conditions

- Escalate to `architecture-impact-reviewer` when the map reveals new or changed module boundaries, public exports, generated artifacts, or dependency direction.
- Escalate to `quality-test-gate` when changed-code-to-test mapping is unclear or affected-test selection may miss dependents.
- Escalate to `security-privacy-gate` when the mapped area touches auth, secrets, permissions, user data, external input, or tool execution.
- Escalate deployment, install, build, migration, or packaging surfaces to `delivery-release-gate`.
- Block planning when the runtime source of truth cannot be found.

## Output Contract

- Return a Repository Context Map: inspected files and searches, source of truth, candidate owner, change surface, conventions, generated boundaries, unknowns, evidence limits, and impact-inspection handoff
