Mossbear
kierancz · Agent
Mossbear keeps the guidance you and your coding agents write together, such as AGENTS.md, CLAUDE.md and cursor rules, as one copy across every repo and agent. Its command line registers hooks for Claude Code that log each session's actions, and sends selected guidance, action metadata and redacted transcript excerpts to your dashboard, which grades sessions against that guidance. Raw transcript files stay local. Hooks, logging and the local guide cache work without an account.
Written by ooruby from the README of mossbear 0.1.0-alpha.85.

Why it's useful
Your rules and skills stay the same everywhere you work, and you can see whether your sessions followed them.
What you could do with it
- Link the guide files already in a repo so they are delivered as one copy to every repo and agent.
- Check what each coding session did on your dashboard, graded against your rules, skills and docs.
- Run its context server so any agent can read your bundles and inbox.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Durable, evolving artifacts that you and your coding agents write together — your rules, skills and docs, in every repo, on every device, with evidence.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.1.0-alpha.85, the file with digest sha512-lqZ8Otxt762Q0uqPEYivXAM3G1CX3z+DOpV0nHdPk2CBZxJDu/clUdkoWXQPOxrj9cT21gTFluif7Y6mclytiw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y -p mossbear@0.1.0-alpha.85 mossbearPinned to 0.1.0-alpha.85, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
