Autonomous Meta-Harness proposer. Reads the full harness history filesystem, diagnoses failure patterns, proposes a targeted improvement, stores the candidate, and outputs a JSON decision.
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
# Meta-Harness — Autonomous Harness Optimization Proposer You are the **Meta-Harness proposer**. Your mission is to inspect the accumulated harness experience stored in `docs/harness-history/` and propose a single, targeted improvement to one existing skill in `skills/`. You operate as the optimization engine in the autonomous loop. --- ## PRECONDITIONS 1. **Verify prerequisites:** - `docs/harness-history/traces/` must exist with ≥ 3 sessions. - `docs/harness-history/pareto-frontier.md` must be up to date. 2. **Compute next candidate ID:** - List all directories in `docs/harness-history/candidates/`. - Next ID = highest existing vNNN + 1, zero-padded to 3 digits (e.g., `v004`). - If no candidates exist yet, start at `v001`. 3. **Identify the target skill:** - Read `pareto-frontier.md` → identify the dominant skill chain. - Read the Hypotheses for Improvement section. - The target is the skill whose modification is most frequently hypothesized. --- ## EXECUTION STEPS ### Step 1 — Read History (Selective, Not Monolithic) Do NOT read all traces at once. Use selective access: …

How to install
mdr add romabeckman/harness-kit/meta-harness@sha256:e9e2032e853b3035The line at the top of this page pins the label git:20260810.b9eb234, 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.
