Opt this repo into codeArbiter — scaffold the root-level .codearbiter/ state store.

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

# $ca-init — first-run scaffold

Stand up the root-level `.codearbiter/` project-state store that opts a repo into arbiter
management. This is the v2 replacement for vendoring/`init-vendor`: no symlinks, no shims, no dual
root. It writes the activation flag and the empty state files, then hands off to the populator.

`.codearbiter/CONTEXT.md` frontmatter `arbiter: enabled` is the single activation flag — it gates
the SessionStart persona injection. The scaffolded
`CONTEXT.md` is a **stub** (no initialization sentinel), so after scaffolding the project still needs
populating before normal operation.

<!-- catalog-command-modes:start -->
## Explicit population strategies

<!-- command-mode:--greenfield legacy-route:decompose -->
`--greenfield` selects the exact [skills/ca-decompose/SKILL.md](../ca-decompose/SKILL.md) workflow.

<!-- command-mode:--brownfield legacy-route:create-context -->
`--brownfield` selects the exact [skills/ca-create-context/SKILL.md](../ca-create-context/SKILL.md) workflow.
That workflow populates an uninitialized stub. For an initialized brownfield
project, keep the existing marker and route source-observed acquisition and

How to install

The exact contents, by fingerprint
mdr add arbiterforge/codearbiter/ca-init@sha256:10ac7467cda5c172

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.
