        description: `Comprehensive workflow version management system. Supports six operations:

**list** - Show version history for a workflow
- Returns all saved versions with timestamps, snapshot sizes, and metadata
- Use limit parameter to control how many versions to return

**get** - Get details of a specific version
- Returns the complete workflow snapshot from that version
- Use to compare versions or extract old configurations

**rollback** - Restore workflow to a previous version
- Creates a backup of the current workflow before rollback
- Optionally validates the workflow structure before applying
- Returns the restored workflow and backup version ID

**delete** - Delete specific version(s)
- Delete a single version by versionId
- Delete all versions for a workflow with deleteAll: true

**prune** - Clean up old versions
- Keeps only the N most recent versions (default: 10)
- Useful for managing storage and keeping history manageable

**truncate** - Delete ALL versions for ALL workflows
- Dangerous operation requiring explicit confirmation
- Use for complete version history cleanup`,

        performance: `Performance varies by operation:
- list: Fast (~100ms) - simple database query
- get: Fast (~100ms) - single row retrieval
- rollback: Moderate (~200-500ms) - includes backup creation and workflow update
- delete: Fast (~50-100ms) - database delete operation
- prune: Moderate (~100-300ms) - depends on number of versions to delete
- truncate: Slow (1-5s) - deletes all records across all workflows`,
        modeComparison: `| Mode | Required Params | Optional Params | Risk Level |

        bestPractices: [
            'Always list versions before rollback to pick the right one',

        pitfalls: [
            'Rollback overwrites current workflow - backup is created automatically',
