Eval-only bounded frontier stress test for complex repo-harness planning; never installed as a managed Skill.
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
# Bounded frontier stress test — eval treatment This is an evaluation-only delta over the fixture's minimum-effective-interview baseline. It has no authority to approve or implement a plan. ## Eligibility Use the treatment only when explicitly requested or when a case changes high-risk architecture, data authority or ownership, security, permissions, money, deletion, concurrency, recovery semantics, or a hard-to-reverse public interface. Bypass it for small bug fixes, decision-complete acceptance criteria, documentation, formatting, and renames. ## Protocol 1. Resolve environment facts from `CASE.md`; do not ask the user for known facts. 2. Model only high-impact decisions and their prerequisites. A decision enters the current frontier only after every prerequisite is resolved. 3. Emit at most three frontier questions per round. Each question includes a recommended default and the effect of every option. 4. Stop after two rounds per invocation. Further expansion requires explicit `continue`; unvisited branches remain explicit. 5. Never answer a user-owned decision. Mark it `[UNKNOWN:BLOCKING]` and keep the plan `Draft`. …

How to install
mdr add ancienttwo/repo-harness/repo-harness@sha256:bf1b99827593679fThe line at the top of this page pins the label git:20260904.1f5e861, 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.
