Skill manifest

/ca-create-context — brownfield populate

Compatibility route. Prefer /ca-init --brownfield for new usage. This installed route remains functional under the command-route compatibility policy at

Wraps an existing codebase in project state without guessing. Dispatches parallel scouts to read the repository, synthesizes their findings into the surviving .codearbiter/ doc set, resolves gaps via a targeted interview, and locks the project initialized. No arguments — the skill reads the repo and asks only what it cannot determine.

The only permitted path to populate .codearbiter/ when meaningful source code already exists. For a greenfield project with no source, use /ca-decompose.

Routes to

The context-creation skill (<plugin-root>/routines/context-creation/SKILL.md) — six gated phases: pre-flight, scout dispatch, synthesis, gap interview, write, lock. Scouts return paths, line numbers, and named values only — never raw source or secret values. The skill is canonical for the phases and their gates.

When NOT to use

Project already initialized ( in CONTEXT.md) → /ca-status.
Greenfield project, no source → /ca-decompose.
.codearbiter/ not yet scaffolded → /ca-init first.
Update one doc → edit <project-root>/.codearbiter/ directly or use /ca-feature.

Hard gate

BLOCK if  is already present in CONTEXT.md. BLOCK if no meaningful source exists (route to /ca-decompose). BLOCK if any scout fails to return before synthesis. BLOCK if any [CONFIRM-NN] exits the gap interview unresolved and undeferred. MUST NOT write  until every gap is resolved or deferred to open-questions.md.

Wraps an existing codebase in project state without guessing. Dispatches parallel scouts to read the repository, synthesizes their findings into the surviving `.codearbiter/` doc set, resolves gaps via a targeted interview, and locks the project initialized. No arguments — the skill reads the repo and asks only what it cannot determine.

The only permitted path to populate `.codearbiter/` when meaningful source code already exists. For a greenfield project with no source, use `/ca-decompose`.

## Routes to

The `context-creation` skill (`<plugin-root>/routines/context-creation/SKILL.md`) — six gated
phases: pre-flight, scout dispatch, synthesis, gap interview, write, lock. Scouts return paths, line
numbers, and named values only — never raw source or secret values. The skill is canonical for the
phases and their gates.

## When NOT to use

- Project already initialized (`<!--INITIALIZED-->` in `CONTEXT.md`) → `/ca-status`.
- Greenfield project, no source → `/ca-decompose`.
- `.codearbiter/` not yet scaffolded → `/ca-init` first.
- Update one doc → edit `<project-root>/.codearbiter/` directly or use `/ca-feature`.

## Hard gate

BLOCK if `<!--INITIALIZED-->` is already present in `CONTEXT.md`. BLOCK if no meaningful source exists
(route to `/ca-decompose`). BLOCK if any scout fails to return before synthesis. BLOCK if any
`[CONFIRM-NN]` exits the gap interview unresolved and undeferred. MUST NOT write `<!--INITIALIZED-->`
until every gap is resolved or deferred to `open-questions.md`.
