Importance: Medium. Task status: This rewrite is Complete. Two follow-on items are Pending (see end).
What was done
- Took the existing Monthly Home-Folder Duplicate Scan (1st of month, 3 AM, strictly read-only) and rewrote it into an autonomous, goal-directed task.
- Converted it to a slash command,
/monthly-dedupe, with a single GOAL line so the schedule just fires the command (no logic in the scheduler).
- Changed posture from scan-and-propose to scan-and-execute: redundant duplicates are now moved to macOS Trash (reversible) instead of being left as a proposal. No
rm, no permanent deletion.
- Added the safety spine that makes autonomous removal safe:
- Rollback manifest (
dedupe-manifest-YYYY-MM-DD.json) plus a generated restore-YYYY-MM-DD.sh that puts every trashed file back.
- Verify-before-move re-hash to defeat drift/stale-scan races.
- Circuit breakers: escalate (4-way MC, act on nothing) if a run would trash >5 GB, >500 files, or hit >25 ambiguous-canonical groups.
- Never-touch guards: files <7 days old, locked/open files, sole copies, all-copies-in-excluded-dirs.
- Deterministic canonical-copy selection so exactly one safe copy survives per group; ambiguous groups are skipped, never trashed.
- Kept all prior structure (Step 0 stale-staging alert with iMessage + Teams + Notion banner, pre-flight df, scan with same includes/excludes and 100 KB floor + full MD5, dated JSON report, QA reflection).
- Applied skills-hygiene: config (roots, excludes, thresholds, Sam's iMessage/Teams IDs, script path) is sourced from a Notion config page with local values as fallback, and the dedupe script is referenced from
sail-skills, not pinned to one machine path.
- Reviewed the existing
folder-cleanup skill first; it is interactive/approval-gated, so the monthly autonomous job is a separate skill that reuses its hashing logic rather than overloading it.
Why the session ended
Scope was a single focused task rewrite and it is complete. The deliverable file is produced and this export is the required session log.
Recommended next actions
- Decide on the autonomous removal target: Trash-with-rollback (recommended) vs custom quarantine vs auto-purge after retention.
- Commit the new
monthly-dedupe skill to samaguiar1982-cpu/sail-skills (via github-direct-commit on the Mac; Pipedream GitHub is unreliable for large files).
- Create the Monthly Dedupe Config Notion page so the task reads roots/excludes/thresholds/IDs from a non-drifting source.
- Point the existing scheduled task at
/monthly-dedupe and retire the old read-only body.
Handoff for next agent
The deliverable is monthly-dedupe-task-UPDATED.md (produced this session in the chat outputs). It contains the full slash-command spec, the current-vs-proposed table, the safety architecture, Steps 0-4, and the QA block. Nothing has been committed to the repo and no Notion config page exists yet, so treat those as open. The design intentionally uses move-to-Trash (reversible) as the autonomous action and leaves emptying Trash as the only manual/destructive step, which is what reconciles Sam's 'execute, do not just scan' instruction with his 'ask first on destructive deletions' rule. If Sam approves auto-purge, it is a single config flag (AUTO_PURGE_AFTER_DAYS). You have as much latitude here as I did; adjust the thresholds or canonical-selection chain if real-run data suggests better defaults.
Pending (awaiting Sam)
- Commit skill to sail-skills (needs confirmation it runs from Mac/Cowork, not this chat).
