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 | $0.00041 | $0.00389 |
| Opus 5 | $0.00020 | $0.00195 |
| Sonnet 5 | $0.00008 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
repository-onboarding 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 12d 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.
What it actually says
Repository onboarding
Use this skill when a contributor needs a fast, reliable orientation to a repository before making changes.
Primary inputs
README.mdCONTRIBUTING.mdDEVELOPER.md,developer.md, ordocs/development.mdCODE_OF_CONDUCT.mdSECURITY.md- issue templates and pull request templates
- architecture or docs folders
Instructions
- Read the repository's high-signal docs first.
- Summarize:
- what the project does
- who it is for
- how contributors are expected to work
- Extract the contributor workflow:
- setup steps
- build, test, and lint commands
- branching or commit expectations
- pull request expectations
- Identify project norms:
- code of conduct or communication rules
- security reporting instructions
- labels or issue types that indicate where help is needed
- End with the smallest sensible next steps for the contributor.
Recommendations to apply
- Prefer reading the room before suggesting changes.
- Point new contributors to documentation and small starter work first.
- Highlight non-code ways to contribute when the repository supports them.
- If the repo uses labels such as
good first issueorhelp wanted, call them out explicitly.
Output format
Return:
- a short repository summary
- a checklist of first setup steps
- the most important repo norms
- a list of suggested next tasks for a newcomer
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.

hr-onboarding
A new-hire onboarding plan as a single page — first week schedule, buddy + manager intro, learning track, equipment checklist, and "you're set when…" outcomes. Use when the brief mentions "onboarding", "new hire", "first week plan", or "入职".
book-mirror
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's…

eli5
Explain research, papers, or technical ideas in plain English with minimal jargon, concrete analogies, and clear takeaways. Use when the user says "ELI5 this", asks for a simple explanation of a paper or research result, wants jargon removed, or asks what something technically dense actually means.
