A session-closing checklist for coding-agent work. It checks Git repositories and worktrees, records the handoff state, and produces a standard closing report.

Use it when wrapping up a coding session, including checking repository status, updating documentation when needed, cleaning limited temporary files, and listing blockers or pending tasks.

It reduces the risk of ending a session without recording changes, test results, unfinished work, or cleanup details.

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 5.1	$0.00034	$0.01544
Opus 5.5	$0.00014	$0.00618
Sonnet 5.5	$0.00007	$0.00309
Haiku 4.5	$0.00003	$0.00154

Security

Grade A, and why

close 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 21d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/code-friction.py, scripts/final-recheck.sh, scripts/final-recheck.test.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.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Close a session

Audit only repositories affected by this session, preserve unrelated work, and complete the authorized handoff. An ordinary reply is not a session close. A close does not authorize publication, deployment, credential operations, or destructive cleanup.

For Git/worktree scope, snapshot exceptions, and the mandatory final concurrency check, read git-audit.
When execution state or project truth changed, read persistence. Skip state rewrites for read-only inspection.
Only for personal notes/workspaces with capture/tasks conventions, read personal-workspace.
For every close, read report-contract and return scripts/render-report.py output verbatim. Preserve all fields in quick mode; missing evidence is not a clean result.
For explicitly enabled code-friction capture, read code-friction. Full Close may prepare a terminal assessment; quick Close only flushes records already in the local outbox.

All script paths are relative to the skill root. Preserve a reversal recipe and audit event for mutations where required by project policy.

Documentation Review

Check if session work requires documentation updates:

AGENTS.md / CLAUDE.md - folder structure, workflows, MCP integrations, skills
Skill SKILL.md files - if skill behavior changed
README files - in relevant folders
Operational/configuration docs - if runtime, deployment, or client assumptions changed
Living / generated artifacts - if the project's canonical instruction file defines maintained artifacts (e.g. a generated site/ of HTML status pages, dashboards), follow its documented update contract and refresh them to reflect this session's work. Skip if this session changed no project state.

Questions to consider:

Did we add new folders? → Update the repository's canonical instruction file
Did we add/modify skills? → Update the canonical instruction file's skills section
Did we change workflows? → Update relevant docs
Did production/runtime behavior change? → Update deployment or client docs and record config drift
Did deployment copy local-only files, require manual cleanup, or change rsync/exclude behavior? → Document the operational fix or verified cleanup location.
Does the canonical instruction file define living artifacts (e.g. site/)? → Apply their documented update contract

What ships with it

13 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.

close is a skill published in the GitHub repository Magnus-Gille/claude-skills (5 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 1,544 once invoked, about $0.0001 per session on Opus 5.5. 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.
