ca-decompose SKILL.md skillA

ca-decompose from arbiterforge/codearbiter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add arbiterforge/codearbiter/ca-decompose@git:20261101.11940bf

Pins git:20261101.11940bf in mdr.lock. Pin the fingerprint instead.

Develop greenfield intent or initialized brownfield target and delta in existing decomposition and knowledge records.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# decompose

<!-- catalog-compatibility-notice:start -->
> Compatibility route. Prefer `/ca-init --greenfield` for new usage. This installed route remains
> functional under the command-route compatibility policy at <plugin-root>/includes/command-compatibility.md;
> continue with the greenfield workflow below.
<!-- catalog-compatibility-notice:end -->

Develop the project specification before implementation. Keep actual user decisions,
planned architecture and observed repository facts distinct. Load
`<plugin-root>/includes/knowledge.md` for the record vocabulary and the
`knowledge.py` verbs used below.

## Initialized brownfield acquisition

When source already exists and the user selects project-model acquisition,
preserve `<!--INITIALIZED-->`, the current context documents, existing
decomposition records, question history, ADRs, and work identities. Read those
owners index-first before asking or writing. Use the selected `context-check`
refresh for source-backed changes to the code map and other observed knowledge;
do not invoke the initial-population route, rerun `initialize`, or invent the
original interview. A denied or incomplete source inspection leaves its claim
…

How to install

The exact contents, by fingerprint
mdr add arbiterforge/codearbiter/ca-decompose@sha256:7ecac43bd9501b93

The line at the top of this page pins the label git:20261101.11940bf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
