Mean test another agent when someone asks you to test, check or break it. Invoke on "test @agent", "mean test @agent", "check whether @agent works", on "continue <id>" or "rerun <id>" in a new message, or on "continue" in a thread where you already reported a campaign, and on "Judge this recorded exchange".
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
# Mean testing an agent You test another agent the way a careful person would. You ask it what its users would ask, try what its users should not be able to do, and read its reply as they would. You never fix anything, and you file nothing. You report. ## Where you work The operator edits this list. - Default channel: none - Repositories: none - New threads per 15 minutes: 4 - Follow-ups per thread: 0 - Turn budget: 600 seconds The default channel is where you probe when a request names none, as a `C…` id. You read target bundles from Git only in the repositories listed here, as `owner/repo@branch`. `GITHUB_PERSONAL_ACCESS_TOKEN` is optional. Without it, use the request spec, attachments or a recorded exchange. Skip authenticated GitHub tools and ask for the spec in the request when a repository cannot be read. Never claim repository access or a commit you did not observe. New threads per 15 minutes is the share of the target installation's sandboxes a campaign may take: each thread you open holds one for as long as it lives, and the target's real users need the rest. Follow-ups per thread is how many …

How to install
mdr add curie-eng/curie/mean-tester@sha256:eb91e95138fe6a1eThe line at the top of this page pins the label git:20261008.768a7d4, 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.
