Claude Hygiene Skill

Manage and maintain ~/.claude/ data: audit sizes, archive old sessions, extract learnings, and clean up low-value files.

Usage

/claude-hygiene                    # Show help
/claude-hygiene report             # Audit current state
/claude-hygiene archive            # Archive old sessions (dry-run)
/claude-hygiene extract            # Find high-value sessions
/claude-hygiene clean              # Show cleanup targets

Commands

Run all commands via Bun from the skill directory:

SKILL_DIR=~/dev/whoabuddy/claude-knowledge/claude-config/skills/claude-hygiene

Report

Audit all .claude data with size breakdown, session age distribution, and reclaimable space estimates.

bun run $SKILL_DIR/src/hygiene.ts report
bun run $SKILL_DIR/src/hygiene.ts report --json
bun run $SKILL_DIR/src/hygiene.ts report --threshold 14

Archive

Compress old session JSONL files with gzip and move to ~/logs/archive/claude/sessions/{YYYY-MM}/.

bun run $SKILL_DIR/src/hygiene.ts archive                    # Dry run (default)
bun run $SKILL_DIR/src/hygiene.ts archive --no-dry-run       # Actually archive
bun run $SKILL_DIR/src/hygiene.ts archive --threshold 14     # Archive sessions >14 days old
bun run $SKILL_DIR/src/hygiene.ts archive --no-dry-run --delete-originals  # Archive + delete

Extract

Score sessions by heuristics and generate a review file for manual knowledge curation.

bun run $SKILL_DIR/src/hygiene.ts extract                    # Last 90 days, score >= 3
bun run $SKILL_DIR/src/hygiene.ts extract --days 30          # Last 30 days only
bun run $SKILL_DIR/src/hygiene.ts extract --project ~/dev/aibtcdev/x402-api
bun run $SKILL_DIR/src/hygiene.ts extract --threshold 5      # Only high-value sessions

Output goes to ~/logs/archive/claude/extractions/.

Clean

Delete low-value files. Always preview first with dry-run (default).

bun run $SKILL_DIR/src/hygiene.ts clean                      # Show all targets
bun run $SKILL_DIR/src/hygiene.ts clean --todos              # Dry-run empty todos
bun run $SKILL_DIR/src/hygiene.ts clean --todos --no-dry-run # Actually delete
bun run $SKILL_DIR/src/hygiene.ts clean --debug --no-dry-run # Delete debug logs
bun run $SKILL_DIR/src/hygiene.ts clean --delete-archived --confirm --no-dry-run  # Delete archived originals

Workflow

When the user invokes /claude-hygiene, determine the intent:

1. No args or "report" - Run the report command and display results
2. Specific command - Run that command with the given flags
3. "weekly" - Run report, then suggest archive + extract based on results
4. "monthly" - Run report, archive --no-dry-run, extract, then suggest clean targets

Always show dry-run results first before performing destructive operations.

State

Processing state is tracked at ~/.claude/.hygiene/state.json to avoid re-processing sessions. Archive manifest is at ~/logs/archive/claude/manifest.jsonl.
