using-cap-evolve SKILL.md skillA

using-cap-evolve from skillberry-ai/cap-evolve is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add skillberry-ai/cap-evolve/using-cap-evolve@git:20260923.249261a

Pins git:20260923.249261a in mdr.lock. Pin the fingerprint instead.

Front door for cap-evolve: routes an optimization request to the right pipeline phase. Use when someone wants an agent, skill, system prompt, tool surface, or MCP toolset to score higher on an eval, benchmark, or task suite — "optimize my skill", "raise the pass rate on these tasks", "my agent keeps failing these cases", "get this prompt''s accuracy up on my evals" — even when they never say "optimize", and whenever a .capevolve/ project or an unfinished run is in the tree. Routes to intake…

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

# using-cap-evolve — the router

The front door: it works out *where the user is* and hands off, running no phase and
editing nothing. Boundary: this router picks the door, `orchestrate` drives the run.

## Routing decision
Run from the user's project dir; `S` is the absolute path of the directory you loaded this
SKILL.md from — the one location always known here (no env var is set for a plugin install):
```bash
S=<this skill's own directory>; python "$S/scripts/run.py" --base .capevolve
```
Follow `next`; pass `reason` on to the user. Two things the JSON cannot say for itself:
- On a fresh request go through `intake`, and if an input it needs is missing, ask the
  user for it rather than inventing one (`intake` owns that rule).
- An existing run is never restarted from zero: interrupted → `cap-evolve run --resume`;
  sealed and the user wants another attempt → `cap-evolve run --reuse-baseline <run dir>`.

## Three ways to run — `orchestrate` has the detail
1. **Phase chain** — `/cap-evolve:<phase>` turn by turn, so each step is inspected.
2. **Deterministic** — `cap-evolve run --spec .capevolve/project/capevolve.yaml`

How to install

The exact contents, by fingerprint
mdr add skillberry-ai/cap-evolve/using-cap-evolve@sha256:45060700484ae248

The line at the top of this page pins the label git:20260923.249261a, 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.
