Manages skill version history and automated improvement cycles. Use for: evolve skills, version skills, skill maintenance, `skill-evolver`.
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 Engine ## When to Use - User says **evolve skills** or task matches this capability - User says **version skills** or task matches this capability - User says **skill maintenance** or task matches this capability ## Workflow 1. Snapshot the current SKILL.md to a local versioned backup and run the hyper-skill-tester baseline. 2. Prepare the proposed evolution as a reviewable diff with expected benefits, risks, and rollback path. 3. Obtain explicit user approval before applying, committing, publishing, or otherwise persisting the proposed change. 4. After approval, apply the change and compare scores. Present any regression and its rollback option for approval rather than rolling back automatically. ## Integrations - `skill-evolver` - `evolution` - `evolver` - `hyper-skill-tester` ## Error Handling | Failure | Response | |---------|----------| | Score regression | Preserve the evidence, present the latest backup and rollback diff, and wait for user approval before restoring. | ## Gotchas - Keep version backups locally; do not publish, delete, or restore them without explicit user approval. ## Example **Input:** User request matching triggers above. …

How to install
mdr add stijnman/grok-custom-skills/skill-evolution-engine@sha256:f24ad40156df472bThe line at the top of this page pins the label v1.2.1, 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.
