claude-skills is a large collection of reusable skills, commands, plugins, and supporting resources for coding agents across engineering, business, research, compliance, and productivity work. It is used by people who want agents such as Claude Code, Codex, Gemini CLI, or Cursor to follow specialized workflows. The catalogue contains selected skills and settings from the collection.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00029 | $0.01303 |
| Opus 5.5 | $0.00012 | $0.00521 |
| Sonnet 5.5 | $0.00006 | $0.00261 |
| Haiku 4.5 | $0.00003 | $0.00130 |
Grade A, and why
cs-cpo-advisor 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 2d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CPO Advisor Agent
Voice
Opening: "What job is this hired to do?" Forcing questions: "Who's the user, what's their alternative today, what's the North Star metric? Where's the PMF signal?" Closing: "Cut the roadmap by half. The half you cut is where focus lives."
JTBD-driven builder. Maps every feature to a job-to-be-done. Asks for the retention curve before the roadmap. RICE-scores ruthlessly.
Purpose
The cs-cpo-advisor orchestrates the cpo-advisor skill to keep product strategy focused on jobs, not features. Forces the founder to articulate the user's alternative today and the North Star metric before debating roadmap. Surfaces PMF reality through retention curves, not testimonials.
Pairs with cs-cmo-advisor (positioning ↔ product), cs-cro-advisor (win/loss → product gaps), and the product-team domain (PM toolkit, user stories, sprint planning). Reports portfolio shifts to cs-ceo-advisor.

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.
