Artifact Consolidation

Overview

Session-based workflows generate artifacts: plan files, handoff archives, feature task directories, execution trackers. These accumulate indefinitely unless actively pruned. This skill consolidates them in bulk.

For distill-then-delete: If you want to extract knowledge into wiki documents before deleting artifacts, use /distill instead. This skill prunes without extracting; /distill extracts into docs/guides/ and docs/decisions/ first.

This is a destructive operation — it deletes files. Always start with a dry run. The PM approves the plan before any deletions.

Scope

| Directory | What accumulates | Pruning strategy | |-----------|-----------------|-----------------| | plans/ | Session plan files (*.md) | Delete plans older than 14 days with no open references | | archive/handoffs/ | Consumed handoff files | Keep the most recent 10; delete the rest | | tasks/*/ | Feature task directories | Delete dirs where all items are [x] completed and the feature branch is merged | | tasks/handoffs/ | Active handoffs | Chain-aware archival (handled by handoff-archival); this skill does NOT touch active handoffs |

Steps

Phase 1: Inventory (Dry Run)

Run this phase first, always. Present the results to the PM before proceeding.

1. Count artifacts:

   • plans/ — count .md files, note oldest and newest timestamps
   • archive/handoffs/ — count files
   • tasks/*/ — list feature directories, note which have all items completed
   • Report total file count and disk usage (du -sh each directory)

2. Classify each artifact as KEEP or PRUNE:

   Plans (plans/*.md):

   • PRUNE if: file is older than 14 days AND not referenced by any active handoff, task file, or MEMORY.md entry
   • KEEP if: referenced by an active handoff or in-progress task dir, OR younger than 14 days
   • To check references: grep the filename across tasks/handoffs/, tasks/, and MEMORY.md

   Archived handoffs (archive/handoffs/*.md):

   • KEEP the 10 most recent by filename timestamp
   • PRUNE the rest — they've been consumed and their context lives in successor handoffs

   Feature task directories (tasks/<feature>/):

   • PRUNE if: todo.md exists and all items are [x], AND no lessons.md with unmerged entries, AND the feature branch (if identifiable from the dir name) is merged or deleted
   • KEEP if: any [ ] items remain, or contains unmerged lessons
   • Never delete tasks/lessons.md (global), tasks/health-ledger.md, tasks/bug-backlog.md, tasks/debt-backlog.md, or tasks/architecture-atlas/

3. Present the dry-run report:

   ## Artifact Consolidation — Dry Run
   
   | Category | Total | Keep | Prune |
   |----------|-------|------|-------|
   | Plans | N | N | N |
   | Archived handoffs | N | N | N |
   | Feature task dirs | N | N | N |
   
   **Total files to delete:** N
   **Disk to reclaim:** ~Xkb
   
   ### Files to prune:
   - plans/2026-01-15-foo.md (67 days old, no references)
   - ...
   
   ### Files to keep:
   - plans/2026-03-18-bar.md (2 days old)
   - ...
   

4. Wait for PM approval. Do not proceed to Phase 2 without explicit confirmation.

Phase 2: Execute Pruning

1. Create a safety commit before any deletions:

   git add -A && git commit -m "pre-consolidation checkpoint"
   

2. Delete PRUNE-classified files using git rm (so deletions are tracked in git history):

   • Plans: git rm plans/<file>
   • Archived handoffs: git rm archive/handoffs/<file>
   • Feature task dirs: git rm -r tasks/<feature>/

3. Remove empty directories left behind (git doesn't track empty dirs, but the filesystem might retain them)

4. Commit the consolidation:

   git add -A && git commit -m "artifact consolidation: pruned N plans, N handoffs, N task dirs"
   

5. Report results:

   ## Consolidation Complete
   
   - Deleted N plan files
   - Deleted N archived handoffs
   - Deleted N feature task directories
   - Reclaimed ~Xkb
   - Safety commit: <hash> (revert target if needed)
   

Tuning

The defaults (14-day plan retention, 10 archived handoffs) are starting points. Override with arguments:

• /artifact-consolidation --plan-age 30 — keep plans younger than 30 days
• /artifact-consolidation --keep-handoffs 20 — keep 20 most recent archived handoffs
• /artifact-consolidation --dry-run — inventory only, no deletions (default on first run)

Notes

• This skill is standalone — not part of /update-docs. Invoke it explicitly when artifact bloat is noticeable.
• The safety commit ensures git revert can undo the entire consolidation in one step.
• For repos with 200k+ artifacts, consider running Phase 1 with find | wc -l rather than listing individual files — present counts and size, not filenames.
• Never delete the architecture atlas (tasks/architecture-atlas/), global tracking files, or active handoffs. When in doubt, keep.
