name	snapshot-regen
description	Regenerate a coach's context-snapshot.md file based on current state of profile, program, vocabulary, and recent sessions. Invoke after any substantive update via obsidian-sync skill, or when user asks for a "fresh snapshot" or "update phone snapshot".

Skill: snapshot-regen

The context-snapshot.md file is the digest that phone-Claude reads first to get current context. It must be kept fresh so that mobile sessions don't operate on stale data.

When to invoke

• After substantive updates to profile.md, program.md, vocabulary.md, or after a new sessions.md entry
• When user explicitly asks: "update my snapshot", "refresh phone context", "regenerate snapshot"
• At the end of any conversation that ran the obsidian-sync skill

What to do

1. Read all four sources for the coach:

   • Coaches/<Coach>/profile.md
   • Coaches/<Coach>/program.md
   • Coaches/<Coach>/vocabulary.md (just status, not full definitions)
   • Coaches/<Coach>/sessions.md (last 3-5 entries)

2. Also read _shared/profile.md for global facts.

3. Compose a compact digest (~500-1000 words max) covering:

   • Who: 1-2 sentence user summary (age, body, key context)
   • Studio / setup: where they train
   • Level: current self-assessed level
   • Repertoire: clean moves, drifting moves, current edge
   • Active block: name, week, focus areas
   • Recent context: last 2-3 session summaries (compressed)
   • Open gaps: things still to discover
   • Coaching priorities: what to emphasize
   • How to greet: what a "welcome back" should reference

4. Write to Coaches/<Coach>/context-snapshot.md, replacing the previous content (this file is regenerated, not appended).

5. Update the last_regenerated field in frontmatter to today's date.

Why this matters

This is the file phone-Claude (via Drive connector) reads to bootstrap context. If it's stale, mobile sessions will give stale advice. A coaching system without a fresh snapshot = a coaching system that forgets what happened on Mac.

Don't

• Don't include full file contents (it's a digest, not a copy)
• Don't include session-by-session details (only patterns and recent highlights)
• Don't omit the open gaps section — surfaces what to ask next
