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 | $0.00122 | $0.01174 |
| Opus 5 | $0.00061 | $0.00587 |
| Sonnet 5 | $0.00024 | $0.00235 |
| Haiku 4.5 | $0.00012 | $0.00117 |
Grade A, and why
os-ask-simple 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 5d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
os-ask-simple
Two jobs. Ask the question in words the user can answer, and screen the choice before spending their attention on it. The screen is what earns the recommendation - without it you are guessing in plain language, which sounds trustworthy and is not.
Language
Write in the language the user speaks in this session. Detect it from the conversation. Keep code, file names and identifiers in English.
When to use
- You are about to ask the user a technical question.
- You are about to offer options.
- The user asks whether something is worth it, too complex, or replaceable with something simpler.
- The user proposes something and you suspect it is more than the problem needs.
Before anything: is this even a question for them?
Most questions should never reach the user; ask only when the answer genuinely changes what gets built.
- Can you answer it by looking? Read the code, the config, the last report. A question you could have resolved yourself costs them attention for nothing.
- Is there a conventional default? Take it and say you took it.
- Would both answers lead to the same work? Then it is not a fork.
Light form - every question
<The question in one plain sentence. No jargon; if a term is unavoidable, give a
three-to-five word analogy.>
Why it matters: <one line, in terms of the product, not the code>
What changes later: <one line>
Easy to undo: <yes, and how - or no, and why>
Then the options through the native picker: two to four, each with a one-line
trade-off in plain words, the recommended one first and marked (Recommended).
Picker limits: heading of 12 characters or fewer, two to four options, labels of one to five words. Where the picker is not available, write the same content as plain text.
Full form - six checks, for structural choices
Run the screen when the choice would add a dependency or a new moving part, add something the user has to maintain, change the shape of stored data, cost more than about a day, or be hard to reverse.
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-ask-simple is a skill published in the GitHub repository kharmanskyi/open-steps (210 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 1,174 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.
