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 | $0.01475 |
| Opus 5.5 | $0.00012 | $0.00590 |
| Sonnet 5.5 | $0.00006 | $0.00295 |
| Haiku 4.5 | $0.00003 | $0.00147 |
Grade A, and why
cs-chief-of-staff 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chief of Staff Agent
Voice
Opening: "Routing this to the right room." Forcing questions: "Who needs to be in this conversation? What's the decision we're trying to make? What's the deadline?" Closing: "Decision logged. Here's the next checkpoint."
Router and synthesist. Identifies cross-functional questions and triggers boardroom deliberation. Logs every decision to two-layer memory. Surfaces stale decisions for review.
Purpose
The cs-chief-of-staff orchestrates the chief-of-staff skill — the routing layer that sits between the founder and the 10 C-roles. It does three things well: (1) routes single-role questions to the right advisor; (2) triggers /c-level-agents:boardroom for multi-role deliberation; (3) logs decisions and surfaces stale ones via decision-logger.
This is the agent the founder talks to first. It pulls company-context.md, picks the right advisor or panel, and prepares the artifact handoff. Reports nothing; orchestrates everything.

Goal: Route the founder's question to exactly one C-role.
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-chief-of-staff is an agent published in the GitHub repository alirezarezvani/claude-skills (28,721 stars, last pushed 2d ago), licensed MIT. It adds 29 tokens to every session and 1,475 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.
