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 | $0.00081 | $0.02870 |
| Opus 5.5 | $0.00032 | $0.01148 |
| Sonnet 5.5 | $0.00016 | $0.00574 |
| Haiku 4.5 | $0.00008 | $0.00287 |
Grade A, and why
developer-onboarding-doc scanned grade A with 1 finding 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 1mo 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.

Developer Onboarding Document Skill
Produce a complete developer onboarding document for a service or team — covering everything a new engineer needs to be productive within their first week.
A good onboarding doc is not a wiki dump. It answers the questions a new engineer actually has on day one, in the order they'll have them.
Required Inputs
Ask for these if not already provided:
- Service name and what it does
- Team responsible for it
- Tech stack — language(s), framework(s), database(s), message queues, etc.
- Key external dependencies — upstream services, third-party APIs
- Deployment target — Kubernetes, ECS, Lambda, bare metal, etc.
- Local dev setup — how to run locally (Docker Compose, local DB, etc.)
- Testing approach — unit, integration, E2E; test commands
- Deployment process — summary of how code gets to production
- On-call setup — who's on-call, how alerts work
- Contacts — tech lead, platform team, related service owners
Output Format
Developer Onboarding: [Service Name]
Team: [Team name] | Tech lead: [Name] Last updated: [Date] | Updated by: [Name]
If something in this doc is wrong or out of date, fix it now — it will affect every engineer who onboards after you.
What This Service Does
[3–5 sentences. What problem does this service solve? Who calls it, and who does it call? What would break if this service went down?]
Service type: [API / Background worker / Event consumer / Data pipeline / etc.] Consumers: [List internal services or external clients that depend on this service] Dependencies: [List upstream services, databases, and third-party APIs this service calls]
Architecture diagram: [Link or embed — even a rough ASCII diagram helps]
[Caller A] ──→ [This Service] ──→ [Database]

Codebase Orientation
Repository: [Link]
Main branch: [main / master]
Language: [e.g. Go 1.22 / Node.js 20 / Python 3.12]
Framework: [e.g. Express / FastAPI / Gin / Rails]
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.

developer-onboarding-doc is a skill published in the GitHub repository cnfeat/top-pm-skills (55 stars, last pushed 4mo ago), licensed MIT. It adds 81 tokens to every session and 2,870 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

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…
exam-forecast
Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
lean-formalize
Develop and verify a mathematical proof in Lean, continue an incomplete Lean project, or audit whether it proves the original statement. Connect actual inputs to intermediate lemmas, assemble the target theorem, check its transitive axioms, and provide a reproducible handoff. Use when Lean is requested or a specific…
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.
deck-course-module
A course or workshop slide template with persistent learning goals, teaching pages, multiple-choice self-tests, and a wrap-up.
