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.

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 | $0.01416 |
| Opus 5 | $0.00017 | $0.00708 |
| Sonnet 5 | $0.00007 | $0.00283 |
| Haiku 4.5 | $0.00003 | $0.00142 |
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 4d ago.
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 — 110 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.pyoutput verbatim. Preserve all fields in quick mode; missing evidence is not a clean result.
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

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 5d ago), licensed MIT. It adds 34 tokens to every session and 1,416 once invoked, about $0.0002 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.
