edit-manifest SKILL.md skillA
edit-manifest from chrono-meta/forge-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add chrono-meta/forge-harness/edit-manifest@git:20260810.69d1ce6Pins git:20260810.69d1ce6 in mdr.lock. Pin the fingerprint instead.

Implements a predict-verify loop for harness edits. Every SKILL.md, rules/*.md, or CLAUDE.md change is paired with a predicted impact stored in a manifest. The next session verifies predictions against actual outcomes, and a validation gate accepts edits only when improvement is measurable. Runs automatically on harvest-loop Step 0-c and on explicit invocation.
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
# edit-manifest — Predict-Verify Loop for Harness Edits > Implements two mechanisms from frontier harness research, named as in their source papers (both terms > are the papers' own — verified 2026-06-17 against arXiv full text): > - **Change Manifest** (AHE, arXiv:2604.25850): each edit attaches a manifest entry declaring a > falsifiable predicted impact (expected fixes + at-risk regressions); the next round intersects it > with observed task-level deltas to produce a per-edit verdict. (Paper: "the Evolve Agent produces a > change manifest…".) > - **Validation Gate** (SkillOpt, arXiv:2605.23904): a candidate is accepted only when its > selection-split score is strictly greater than the current selection score (ties rejected); rejected > edits are kept in an epoch-local buffer, not silently discarded. (Paper: "validation gate" / > "held-out gate".) FH's regression_guard.sh catches backward regressions. edit-manifest closes the forward loop: did the edit actually improve what it claimed to improve? **Boundary vs. verify-bidirectional**: verify-bidirectional is *reactive* — it updates the …

How to install
mdr add chrono-meta/forge-harness/edit-manifest@sha256:8b5684607f790da2The line at the top of this page pins the label git:20260810.69d1ce6, 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.
