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
-
Read all four sources for the coach:
Coaches/<Coach>/profile.mdCoaches/<Coach>/program.mdCoaches/<Coach>/vocabulary.md (just status, not full definitions)Coaches/<Coach>/sessions.md (last 3-5 entries)
-
Also read _shared/profile.md for global facts.
-
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
-
Write to Coaches/<Coach>/context-snapshot.md, replacing the previous content (this file is regenerated, not appended).
-
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 โ surfaces what to ask next
