Skill Version Awareness

Track and manage Agent Skill versions with change visibility and rollback capability.

Core Capabilities

1. Version Fingerprinting

Hash-based version identification (SHA-256 of SKILL.md content)
Git commit SHA for repository-backed skills
Semantic versioning for published skills

2. Change Summary

Diff-based change detection between versions
LLM-generated natural language summary of changes
Classification: trigger change, output change, tool change, structural change

3. Dependency Validation

Track external tool dependencies (CLI tools, APIs, packages)
Validate dependencies are still available after update
Detect dependency version conflicts

4. Behavior Regression Detection

Compare test results before and after update
Flag new test failures as potential regressions
Generate regression report with before/after comparison

5. One-Click Rollback

Git-based rollback to any previous version
Preserve rollback history
Validate skill functionality after rollback

Workflow

Before Update

Run current version's test suite → save baseline
Record current fingerprint

After Update

Compute new fingerprint
Generate change summary (diff + LLM)
Validate dependencies
Run test suite → compare with baseline
If regressions detected: present report, offer rollback

Report Format

## Version Update Report: [Skill Name]

**Before:** [fingerprint/commit]
**After:** [fingerprint/commit]

### Changes
- [Change summary in natural language]

### Dependency Check
| Dependency | Status | Notes |
|-----------|--------|-------|
