Use when running, reviewing or changing coco's self-evolution cycle: the 30-day loop that observes how skills are actually used, proposes evidence-backed edits to them as one branch and one pull request, and lands nothing without the owner's merge. Also use when asked why a skill changed, what the loop would propose next, or how to reject a proposal so it is not raised again.

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

# Skill Evolution

A cycle that improves this repository's own skills from observed use, and proposes every
change for a human to merge. It never writes to `main` and never merges.

**Status:** the scripts this file documents, `scripts/evolve.py` and the steps it runs, are
not on `main` yet, so the commands below do not run today. They land with plan tasks 2 to 9
in `.metagpt/plan.md`: task 2 `ledger.py` through task 8 `evolve.py`, and task 9
`run_fixtures.sh` with the CI join.

## The one rule

**The loop proposes. The owner decides.** There is no confidence level, budget or green gate
that lets it land a change on its own. This is a design invariant, not a setting: a system
that edits the repository that measures it has no natural stopping point.

## What a cycle does

Five steps, and only the second one calls a model.

| Step | Script | Model? | Output |
| --- | --- | --- | --- |
| 1. Observe | `scripts/observe.py` | no | `signals/<cycle>.json`, pinned to one commit |
| 2. Propose | `scripts/propose.py` | yes, one lane | `proposals/<id>.json` and `proposals/<id>.patch` |
| 3. Validate | `scripts/validate.py` | no | accept or refuse, with a reason |

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/skill-evolution@sha256:1c0889ae306a7c96

The line at the top of this page pins the label git:20260925.a9f0fbf, 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.
