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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00072 | $0.04564 |
| Opus 5 | $0.00036 | $0.02282 |
| Sonnet 5 | $0.00014 | $0.00913 |
| Haiku 4.5 | $0.00007 | $0.00456 |
Grade A, and why
write-clear-readme 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 today.
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 — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Write Clear README
Important — Writing rules
Apply these rules to emitted prose: docs, comments, commit messages, PR bodies, and release notes.
- Match surrounding punctuation, capitalization, and formatting.
- Every sentence changes the reader's understanding. Cut it otherwise.
- Lead with the action or outcome.
- Use concrete language and lists when they improve comparison or sequence.
- Assert positively. Reserve negation for real constraints (
NEVER commit secrets). - No marketing words: powerful, robust, seamlessly, leverage, unlock, comprehensive, delightful.
- No AI tells: delve, tapestry, intricate, pivotal, testament, underscore, crucial, garner, showcase, additionally, moreover, furthermore, indeed.
- For substantive English prose, use
/humanize-enif installed with the existing scope and authorization. It adds no approval stage; skip redundant passes over short status text.
Author, audit, or polish a README.md for clarity and scannable structure. Read repository truth first. Explicit author/polish requests authorize local edits; audit/propose stays read-only. Carry this target and mode through a nested prose pass without another approval prompt. Publication is a separate action.

Doc type → pattern
Long READMEs cause scroll fatigue. The fix is a structural decision before any prose: pick one collapse pattern for the whole doc and apply it uniformly. Selective collapse driven by per-section judgment — some sections visible, some hidden — creates a minefield. Readers cannot infer the rule, every heading becomes a guess.
What ships with it
2 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.
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.

write-clear-readme is a skill published in the GitHub repository coroboros/agent-skills (4 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 4,564 once invoked, about $0.0004 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.
