Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00122 | $0.04504 |
| Opus 5.5 | $0.00049 | $0.01802 |
| Sonnet 5.5 | $0.00024 | $0.00901 |
| Haiku 4.5 | $0.00012 | $0.00450 |
Grade A, and why
local-dev-setup 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Local Dev Setup Skill
Produce a complete local development environment setup guide for a service or project — walking a new engineer from zero (a clean laptop) to a working local environment with passing tests in under 30 minutes. A good setup guide reduces onboarding time, prevents the "it works on my machine" problem, and lets engineers make their first contribution with confidence. Write every step as a concrete command or action — not a description of what needs to happen.
Required Inputs
Ask for these if not already provided:
- Service name and what it does
- Tech stack — language, framework, database, cache, message queue, and any external services
- Dependencies — databases, caches, message queues, and external services (mocked or real)
- Test framework — how tests are run and what the test suite covers
- CI/CD platform — GitHub Actions, CircleCI, Jenkins, etc. (for context on what "passing CI" means locally)
Output Format
Local Development Setup: [Service Name]
Tech stack: [Language + version] | [Framework] | [Database] | [Cache] Estimated setup time: [20–30 minutes] on a clean machine Last verified: [Date] on [macOS Ventura 13.x / Ubuntu 22.04] Questions? Ask in [Slack: #[team-channel]] or ping [@tech-lead-handle]
First contribution? Complete setup first (this doc), then read [CONTRIBUTING.md] for code standards and PR process.
Prerequisites
Install these tools before starting. The versions listed are the minimum required — newer patch versions are fine, newer major versions may have compatibility issues.

| [Language runtime — e.g. Go] | [1.22+] | [https://go.dev/dl/ or brew install go] |
| [Docker] | 24.x+ | [https://docs.docker.com/get-docker/] |
| [Docker Compose] | 2.x+ | Included with Docker Desktop; or brew install docker-compose |
| [Make] | Any | Pre-installed on macOS/Linux |
| [Tool — e.g. Node.js] | [20.x+] | [brew install node or https://nodejs.org] |
| [Tool — e.g. psql client] | [15+] | brew install postgresql@15 (client only) |
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.

local-dev-setup is a skill published in the GitHub repository cnfeat/top-pm-skills (55 stars, last pushed 4mo ago), licensed MIT. It adds 122 tokens to every session and 4,504 once invoked, about $0.0005 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.
