Persist Bigpicture to Learnings Hub
Target: $ARGUMENTS
Persists the output of /synthesizing-cc-bigpicture as a dated snapshot in a
learnings hub. Maintains a latest.md pointer (always current) and an
append-only archive for compound cross-session learning.

Workflow
Parse arguments — Apply defaults per Arguments table.
Read input — Read
input-path. If the file does not exist, report error and stop.Create hub directory — Create
hub-pathandhub-path/archive/if absent.Write latest — Write full synthesis content to
hub-path/latest.md. Always overwrite — this is the current-state pointer.Write archive snapshot — Determine today's date (
YYYY-MM-DD).- If
hub-path/archive/YYYY-MM-DD.mddoes not exist, create it with the synthesis content. - If it does exist, append a
---separator followed by the new synthesis content. This preserves all snapshots from the same day.
- If
Report — Confirm paths written and archive entry count for today.
Integration
Runs after /synthesizing-cc-bigpicture. Chain the two skills:
/synthesizing-cc-bigpicture all 7d bigpicture.md
/persisting-bigpicture-learnings bigpicture.md docs/learnings/cc-bigpicture/
Compound Learning
Other skills can read hub-path/latest.md for prior synthesis context:
- synthesizing-cc-bigpicture — Load previous synthesis for incremental update instead of cold start.
- ralph / PRD skills — Reference latest bigpicture for strategic context.
- compacting-context — Include bigpicture summary when compacting at phase boundaries.
Quality Check
latest.mdcontent matches the most recent archive entry- Archive files are append-only — never overwrite, never delete
- Hub path directories created automatically
- Input file validated before any writes
