Build source-backed project context through bounded inspection, optional agents, and record-level knowledge writes.

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.

Wrap an existing codebase in project state, without guessing. Routed to by `/create-context`, and by startup when `.codearbiter/CONTEXT.md` exists but carries no `<!--INITIALIZED-->` body marker and meaningful source code is present. When no meaningful source exists, this is the wrong skill — route to `decompose` instead.

This back-fills from existing source. It complements `/ca-init`, which scaffolds an empty `.codearbiter/` for a fresh project; here the context is derived from what is already on disk. Load `<plugin-root>/includes/knowledge.md` for the record vocabulary and the `knowledge.py` verbs used below.

An initialized refresh is requested through `/ca-status drift` and the
existing `context-check` owner after an explicit scoped or full selection. An

How to install

The exact contents, by fingerprint
mdr add arbiterforge/codearbiter/ca-create-context@sha256:09df48c34393fc2b

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.
