# 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 current SKILL.md to versions/.

- 2. Run hyper-skill-tester baseline.

- 3. Apply evolution proposal from evolution skill.

- 4. Compare scores; commit or rollback.

+ 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 | Auto-rollback to latest versions/ backup. |

+ | Score regression | Preserve the evidence, present the latest backup and rollback diff, and wait for user approval before restoring. |

## Gotchas

- - Keeps last 10 version backups per skill.

+ - Keep version backups locally; do not publish, delete, or restore them without explicit user approval.

## Example

**Input:** User request matching triggers above.

**Output:** Structured result per workflow with integrations invoked as needed.
