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 | $0.00118 | $0.01836 |
| Opus 5 | $0.00059 | $0.00918 |
| Sonnet 5 | $0.00024 | $0.00367 |
| Haiku 4.5 | $0.00012 | $0.00184 |
Grade A, and why
os-check-work 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 6d 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
os-check-work
You are the receiving party: another session says it finished, and your job is to find out whether that is true. Reports run optimistic - they are written by whoever did the work. Triggers live in the description above; one more is taking over work you did not do.
Language
Write in the language the user speaks in this session, detected from the conversation. Code, file names and identifiers stay English.
The stance
- A report is a claim by the party being assessed, and its adjectives are not measurements: "tests are green" vs the count that ran. Ask for the number.
- "Done" is a snapshot: reviews get revoked, branches fall behind, checks flip
- often with no new commit. Re-read immediately before you act.
Two modes
Plural is a sweep: every sibling session, one line each, statuses only. Singular - "accept this", a named session or pull request - is an accept: full verification, then acceptance. A sweep that finds verified-ready work rolls into accepting it - the accept steps run first, never skipped.
Sweep
One line per session, one call per pull request - the reader skims these and reads the closing block. No table:
<name a person recognises (#PR)> - ; <all done? plus proof in 2-4 words, or what is missing>; <archive: yes / not yet>.
- Name from the ticket or PR title, never your shorthand; the change for the product, not a file list.
- A yes carries its proof ("checks green, review approved"); never a bare yes.
- "All done" ≠ "can archive": finished work can still await acceptance.
- Order: needs-the-user, then broken, then still-working - a running session is one word, not a finding.
- No deep verification in a sweep: say what you did not open and what that leaves unverified. Never announce your working mode - "cheap checks" is bookkeeping.
- A session waiting on an answer gets it in the same pass - see "The reply"; when that needs the deep read, the reply becomes the do-this-next.
- Name the sessions you could not read, and why.
What ships with it
1 file 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.
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.

os-check-work is a skill published in the GitHub repository kharmanskyi/open-steps (249 stars, last pushed 2d ago), licensed MIT. It adds 118 tokens to every session and 1,836 once invoked, about $0.0006 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 2026-08-30.
