clean

A repository cleanup workflow that safely handles stale files and leftover build or work artifacts. It checks the project state and archives or removes files that match defined cleanup categories.

In plain words
What is it for?
Use it to identify and archive historical files, old review documents, dated scripts, and other listed repository artifacts. It can also commit the cleanup after the safety checks.
Why use it?
It helps reduce clutter while checking that the project is on the main branch, has no uncommitted changes, and still builds before cleanup.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clean scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Local overrides (read this first). Before following any instruction below, check whether .claude/.local/skills/clean/overrides.md exists. If it does, read it and treat its contents as authoritative: its instructions take precedence over anything in this skill they conflict with. This is the supported way to tailor /clean without forking it — overrides.md lives under .claude/.local/, which sequant update and sync never overwrite.

Repository Cleanup Command

Comprehensive, safe repository cleanup that archives stale files, removes artifacts, and commits changes.

Safety First

Before making ANY changes:

  1. Verify we're on main branch with clean working tree
  2. Run npm run build to ensure current state builds
  3. Create a safety checkpoint (stash any uncommitted work)

Cleanup Categories

Category 1: Safe to Auto-Archive (No Review Needed)

These files are always safe to archive - they're historical artifacts:

Root directory patterns:

  • *.backup files (e.g., CLAUDE.md.backup)
  • CODE_REVIEW_PR_*.md - Old PR reviews
  • *_AUDIT.md files older than 30 days
  • One-off shell scripts with dates in names

docs/ patterns:

  • ISSUE_*_PHASE_*.md - Issue implementation specs (work is done)
  • *_IMPLEMENTATION.md older than 30 days
  • content-audit-*.md - Point-in-time audits
  • City-specific audit files (e.g., NYC_*_AUDIT.md, LA_*_REPORT.md)

Category 2: Review Before Archiving

These need a quick check - might still be referenced:

  • Files in migrations/ (check if applied to database)
  • context/ directory contents
  • Any APPLY_*.md or apply-*.sh files

Category 3: Always Keep

Never archive these:

  • CLAUDE.md - Active project instructions
  • README.md - Project readme
  • docs/WORKFLOW_COMMANDS.md - Active workflow docs
  • docs/patterns/* - Active pattern catalog
  • docs/CONTENT_STANDARDS.md - Active standards
  • Any file modified in the last 7 days

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

clean is a skill published in the GitHub repository sequant-io/sequant (1 stars, last pushed 2d ago), licensed MIT. It adds 5 tokens to every session and 1,448 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
