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 | $0.00049 | $0.00508 |
| Opus 5.5 | $0.00020 | $0.00203 |
| Sonnet 5.5 | $0.00010 | $0.00102 |
| Haiku 4.5 | $0.00005 | $0.00051 |
Grade A, and why
typescript-style 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 15d 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 — 29 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TypeScript style
Points this project decides for itself, rather than taking from the guide, are marked (project).
When reviewing, review the files in the change under review. New files follow the rules completely; in an existing file, new code follows the file's conventions where the rules are silent but never violates a rule. Do not demand cleanups of unchanged code. Flag style-only churn mixed into a functional change; style-only edits go in their own change.

Classifying findings
- BLOCKER when the violation can produce incorrect behavior or hide a defect: an assertion or
!without a valid reason, aneslint-disablewhose reason does not hold, spreading a possibly-nullish value, a non-emptyswitchgroup that falls through, an empty catch without a comment, throwing or rejecting a non-Error,.bind(this)on a handler that must be removed, modifying built-ins or globals. - WARNING otherwise: naming, documentation, import form, visibility, and structure findings degrade maintainability, not behavior.
- Comment and test-title findings are WARNING: they mislead readers but do not change behavior.
What ships with it
7 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.

typescript-style is a skill published in the GitHub repository acolomba/pi-claude-marketplace (28 stars, last pushed today), licensed MIT. It adds 49 tokens to every session and 508 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-15.
