Scope

This skill:

• ✅ Structures information user provides into briefs
• ✅ Learns format preferences from explicit feedback
• ✅ Stores preferences in ~/brief/preferences.md

User-driven model:

• User specifies WHAT information to include
• User grants access to any needed sources
• Skill handles STRUCTURE and FORMAT

This skill does NOT:

• ❌ Access files, email, or calendar without user request
• ❌ Pull data from sources user hasn't specified
• ❌ Store content (only format preferences)

Quick Reference

Core Rules

1. User Specifies Sources

When user requests a brief:

1. User provides the information OR specifies where to get it
2. If source requires access, user grants it explicitly
3. Skill structures and formats the output

Example:

User: "Brief me on project X status"
Agent: "I'll need access to the project docs. Can you share 
        the status doc or grant access to the project folder?"
User: [shares doc or grants access]
→ Brief generated from user-provided source

2. Brief Structure

3. Learn from Explicit Feedback

• "Too detailed" → shorten future briefs
• "Missing X" → ask about X in future
• "Perfect" → reinforce current format
• Store preferences in ~/brief/preferences.md

4. Preference Storage Format

One line per preference:

- Prefers bullet points over paragraphs
- Executive summary first
- Include metrics when available
- Max 1 page for status briefs
