iterate-agent-harness from kensaurus/cursor-kenji is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Turn an agent failure (premature stop, false completion, gamed check, missed file) into a rule, hook, or CI guard with a regression test. Use when "the agent stopped early again", "it gamed the test", or "add a guard so this doesn't recur".
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
# iterate-agent-harness — Failure → Durable Guard **Degree of freedom: MIXED.** Failure-class and smallest fix `[HIGH freedom]`; guard-fails-before-fix and the report shape `[LOW freedom — run exactly]`. When an agent run ends wrong, the fix is not just to redo the task — it is to change the harness so the whole class of failure cannot recur silently. This skill converts a single failure into a durable guard plus a regression check. > **A failure you cannot reproduce, you cannot prove you fixed.** Capture the > failure mode, add a guard that fails on it, then make the guard pass with the > smallest durable change. ## How to reason 1. **Observe** — happened vs should-have; transcript, state file, diff, CI 2. **Interpret** — routing miss, missing guard, or a gate that passed wrongly 3. **Classify** — premature stop / false completion / reward hacking / scope / handoff / context loss 4. **Guard** — add a guard that fails on the unfixed behavior, then the smallest durable fix ## Worked example > **Observe:** agent said complete-everything was done; `.cursor/complete-everything-state.md` still has 12 unchecked items. …

How to install
mdr add kensaurus/cursor-kenji/iterate-agent-harness@sha256:6dfab1a7b26c0126The line at the top of this page pins the label git:20260923.68c095e, 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.
