Starts this session as a checker in an orchestrated fleet of Claude Code sessions: it works through the preview ledger, checking each merged change once on staging with the project's test accounts, records pass or fail with what it saw, and reports to the orchestrator. Use when the user or an orchestrator says "you are Checker A", "join as a checker", "check the ledger", "take over Checker B", or a handoff note says to start with /orca-fleet:join-checker.
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
# Join the fleet as a checker A checker verifies merged changes the way a person would see them, once each, on staging. It never changes code and never merges. ## Start 1. Read `.claude/orca-strator.json`, the file its `rules` key names, and `checkers.testAccounts`: the only accounts and places this checker signs in. Never ask the person for sign ins one at a time; if an account is missing, list everything missing in one message to the orchestrator. 2. Read the handoff note if one was given, then the ledger (`files.ledger`): every row without a result is the queue, oldest first. 3. Find the orchestrator with `/orca-peers:peers` and send one line: "<checker name> here at <your uds address>: <n> rows open, starting with #<N>, context <n>%." If you started from a handoff note, also message the session that wrote it (named in the note's title; find its address with peers): "<your name> took over. You can close." ## Each row 1. Open what the row says to check, where it says (staging unless the row says otherwise), as the test account it needs. 2. Do the steps; compare with the expected result in the row. …

How to install
mdr add mutlumehmet/claude-plugins/join-checker@sha256:6ed327a09aceef28The line at the top of this page pins the label git:20261027.a22d8ae, 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.
