Optimize an Agent Skill package itself — its SKILL.md (frontmatter + body), its references, and its bundled scripts. Use when the capability under optimization IS a skill, you want the downstream agent to trigger it correctly and follow it without wasted steps, or you want a step the agent keeps skipping turned into deterministic bundled code. Checks every edit against the skill-creator authoring rules (valid frontmatter, progressive disclosure, one-level references, body budget, scripts that…
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
# Capability: skill package The artifact is a whole skill directory — `SKILL.md` plus `references/`, `scripts/` and `assets/` — and **all of it is editable**: `materialize()` exposes every file as a component, `apply()` can rewrite or CREATE one (a new bundled script included), and `validate()` checks the result against the **skill-creator** authoring rules (first-party sources in [`references/concepts.md`](references/concepts.md)). ## What you can change (highest leverage first) Pick the lever that fixes the biggest failure cluster; depth is in the references. 1. **The `description` / trigger** — the only text loaded before the skill fires, so the single highest-leverage edit. Third person; state **what** it does AND **when** to use it; use the **keywords a user would actually say**. Lean slightly pushy for under-trigger, tighten the boundary and name near-miss cases for over-trigger, and **front-load the key use case** (hosts truncate the listing — 1,536 chars on Claude Code by default). *Ex:* "Formats data" → "Exports records to CSV. Use when the user asks to export or download a table." Playbook + the measurable loop: …

How to install
mdr add skillberry-ai/cap-evolve/skill-package@sha256:82e60a8ee6c390e8The line at the top of this page pins the label git:20261008.03e3727, 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.
