Check skill routing or behavior, investigate a regression, or compare plugin changes with a base commit.

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

# Eval regression

Use deterministic repository tests first. Stop when the target has no behavioral diff.

Resolve the plugin from the argument or cwd. Its catalog is `evals/evals.json`; the runner is `scripts/run_evals.py` in this skill.
The runner can load the operator's settings and other installed plugins. Its results do not isolate this plugin's effect.
For the native Claude routing cases, use `claude plugin eval` with `--no-publish` and an agreed case and run count.
Require the user to choose agent, model, and effort. Never select a costly model or high effort silently.

## Normal check

1. Select cases by changed paths with `--changed-from <base>`, or name them with `--case`. Do not select the full catalog implicitly.
2. Run the command without `--run`. The runner prints cases, modes, repeats, sessions, timeout, and maximum duration without starting an agent.
3. An approved plan that names this exact run already authorizes it. For a standalone eval, present the run plan and stop once.
4. After approval, repeat the same command with `--run`. Default to candidate-only, one run per case, 180 seconds, and four sessions maximum.

How to install

The exact contents, by fingerprint
mdr add reidemeister94/development-skills/eval-regression@sha256:05e4d1ca22e8faf5

The line at the top of this page pins the label git:20261031.a82a617, 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.
