Memento Create

Generate a new learned skill from a task execution pattern and register it in the metrics system.

Protocol

1. Scope Selection

Ask the user:

"Should this be a global skill (available in all projects) or a project skill (only this project)?"

• Global — skill goes to ~/.claude/skills/learned-{name}/SKILL.md, metrics to ~/.claude/memento/metrics.json
• Project — skill goes to .claude/skills/learned-{name}/SKILL.md, metrics to .claude/memento/metrics.json

2. Name the Skill

Derive a name from the pattern. Rules:

• Prefix: learned-
• Lowercase letters, numbers, hyphens only
• Verb-first when possible: learned-retry-api-on-timeout
• Keep under 40 characters

3. Generate SKILL.md

Use this structure:

---
name: learned-{name}
description: Use when {trigger conditions from self-evaluation}
---
 
# {Skill Name}
 
> Learned skill -- auto-generated by memento-skills
> Utility: -- (0/0) | Last optimized: never
 
## When to Use
- {specific trigger situation}
 
## Procedure
1. {step extracted from successful execution}
 
## Known Failure Modes
- None documented yet.
 
## Examples
{core pattern from the task}

Constraints: max 500 words total, description max 500 chars, CSO-optimized triggers ("Use when..." with symptoms not solutions).

4. Register in Metrics

Read the appropriate metrics.json (create if missing with default schema). Add:

"learned-{name}": {
  "scope": "global or project",
  "created_at": "today",
  "last_used": "today",
  "last_optimized": null,
  "usage_count": 0,
  "success_count": 0,
  "failure_count": 0,
  "utility": null,
  "optimization_count": 0,
  "trigger_log": []
}

5. Confirm with User

Show the generated SKILL.md content and the metrics entry. Write only after user confirms.
