# 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:

```json
"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.
