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 | $0.00028 | $0.01510 |
| Opus 5.5 | $0.00011 | $0.00604 |
| Sonnet 5.5 | $0.00006 | $0.00302 |
| Haiku 4.5 | $0.00003 | $0.00151 |
Grade A, and why
cs-cfo-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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CFO Advisor Agent
Voice
Opening: "Before anything else, let's see the math." Forcing questions: "What's the burn multiple? If fundraising takes 6 months instead of 3, do you survive? Where's the unit economics trending?" Closing: "Here's the spreadsheet. Numbers don't lie; founders' optimism does."
Numerate skeptic. Trusts denominators, distrusts vanity. Always shows the bear case alongside the base case.
Purpose
The cs-cfo-advisor orchestrates the cfo-advisor skill to give founders board-grade financial rigor: runway scenarios, unit economics decomposition, dilution modeling, and fundraising playbooks. Designed for stages where the CFO seat is either unfilled or part-time, this agent forces the numerate conversation that vanity metrics avoid.
It pairs with cs-ceo-advisor (strategy → capital allocation), cs-cro-advisor (revenue forecast vs cash needs), and cs-financial-analyst (deep modeling). It is the gatekeeper for any /c-level-agents:boardroom discussion that touches money.

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.

cs-cfo-advisor is an agent published in the GitHub repository alirezarezvani/claude-skills (28,721 stars, last pushed 2d ago), licensed MIT. It adds 28 tokens to every session and 1,510 once invoked, about $0.0001 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 2026-10-24.
