A session-end checklist for improving an AI coding agent's future work. It can review failed attempts and hook errors, save knowledge to a retrieval system, record completed plans, and recommend the next action.

Use it at the end of coding-agent sessions. It helps commit work, review mistakes, update memory, synchronize completed checklist items, and run the configured cleanup tasks.

It prevents useful lessons and unfinished-task information from being lost when a session ends. It also helps remove duplicate failure rules and keep stored knowledge current.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add skills/es6kr/skills/cleanup

Any agent

npx skills add es6kr/skills --skill cleanup

Clone the repo

git clone --depth 1 https://github.com/es6kr/skills

Made for: Claude Code, Codex.

Or install es6kr, the plugin that ships this one along with the rest of its 28 skills.

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.

Model	Per session	Once invoked
Fable 5	$0.00204	$0.00580
Opus 5	$0.00102	$0.00290
Sonnet 5	$0.00041	$0.00116
Haiku 4.5	$0.00020	$0.00058

Security

Grade A, and why

cleanup 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 4d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (resources/block-cleanup-missing-rename.sh, resources/block-cleanup-option-below-context-gate.sh, resources/block-cleanup-without-claudify.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Cleanup

Sequentially run cleanup tasks before session end.

Topics

Topic	Description	Guide
config	Enable/disable individual tasks	config.md
fa-prune	Deduplicate failed-attempts.md rules	fa-prune.md
hook-review	Review hook errors and suggest improvements	hook-review.md
rag-store	Persist to RAG before session end + sync completed fix_plan items (medium matrix fallback)	rag-store.md
retrospect	Analyze mistakes and record to feedback memory/failed-attempts	retrospect.md
run	5-step sequential execution (commit → self-improve → knowledge persist → checklist record → next-action recommendation) + automated helper script execution (`fa-analyze.py`, `hybrid_sweep_rag.py`, `sync_dual_wiki.py`)	run.md

Quick Reference

Run everything

/cleanup              # run topic (default)
/cleanup run          # explicit run

Files

What ships with it

18 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

cleanup is a skill published in the GitHub repository es6kr/skills (2 stars, last pushed yesterday), licensed MIT. It adds 204 tokens to every session and 580 once invoked, about $0.0010 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.
