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.

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 | $0.00144 | $0.01278 |
| Opus 5 | $0.00072 | $0.00639 |
| Sonnet 5 | $0.00029 | $0.00256 |
| Haiku 4.5 | $0.00014 | $0.00128 |
Grade A, and why
os-say-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 8d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
os-say-simple
A text exists and the user cannot use it. This skill rewrites it into words they can act on - the pack's rescue skill: the others fire at moments of work, this one whenever any text, including your own, needs saying again properly. It changes only the words. Never the facts.
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
- The user asks for simpler or shorter, in any phrasing: "say it simply", "in plain words", "what does this mean", "I don't understand", "too long", "wait, what?", "bro".
- The user pastes text and asks what it says.
- The user gives the skill a number - they want exactly that many points.
Not this skill:
- "Is this true?" is verification -
os-check-work; a restatement stays exactly as true as its source. - "What do I do?" right after an answer that asked the user to act is a
walkthrough -
os-step-by-step. Asked about the road ahead, it isos-whats-next.
What text to restate
- Whatever the user points at: pasted text, a named file, a report in the reports folder. Read it if it is a file.
- Nothing pointed at: your own last substantial answer. A bare "wait, what?" always means the thing you just said.
The controlled-language rules
Drawn from the ideas behind ASD-STE100, the Simplified Technical English standard from aerospace manuals. This pack follows the ideas; it does not claim conformance to the standard.
- One sentence, one idea. In instructions: one action per sentence.
- Active voice. Name who does what - "the check refused the deploy", never "the deploy was refused".
- Short sentences. A sentence that needs a breath in the middle is two.
- One word, one meaning - and one meaning, one word. Never rotate synonyms for the same thing; the reader will assume the difference is meaningful.
- Present tense unless the time itself is the fact.
- Lists over dense paragraphs - but a list is not permission to drop the connections between items.
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-say-simple is a skill published in the GitHub repository kharmanskyi/open-steps (274 stars, last pushed today), licensed MIT. It adds 144 tokens to every session and 1,278 once invoked, about $0.0007 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.
