Run an evaluation against an eval with a specific config
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Based on SOC occupation classification
Compare two eval runs and report what changed. Reads both runs' events, transcripts, and produced artifacts. Writes a short markdown summary classifying differences as regression, improvement, or neutral.
Generalized recursive iteration loop. Runs parallel sub-agents against a target, scores deterministically, diagnoses instruction gaps, applies fixes, and recurses until the stop condition is met or max depth is reached.
Write a handoff document so a new chat can continue the work
Show evaluation results and comparisons
Test-driven development of a Hono/Bun WebSocket application. Read requirements, read tests, build server, verify, iterate until all tests pass.

Run a Claude agent in a workspace, score the result, then compare against the most recent prior run.

run_eval.py handles everything: EVAL.md parsing, config resolution, challenge iteration, prompt templating, and invoke.py delegation. It always runs in stream mode so the agent's transcript is archived to stream.jsonl for /compare to read.
Use run_in_background: true for the run command. Monitor with python3 scripts/dashboard.py --latest.
python3 scripts/dashboard.py --latest --summary
/compare:/compare <prior-run-id> <current-run-id>
To find the prior run id: list evals/<eval>/results/ sorted by mtime, skip the current run, take the next one whose events.jsonl shows the same target and config in agent_started. If there is no prior run, skip the comparison and just show the run result.
The /compare skill spawns a sub-agent that reads both runs' evidence (events, transcript, produced artifacts) and writes a markdown summary. Print its output below the run summary so the developer sees both in one place.
If the developer ran multiple challenges (matrix eval), call /compare once per challenge — each comparison is independent.
