# 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.
