ccc-skills

ccc-skills is a plugin for Claude Code from ooiyeefei/ccc. Its manifest loads nothing; the 15 skills it bundles cost 2,333 tokens per session together, scanned A, original, MIT.

A collection of skills and commands for diagrams, habit tracking, agent design, web pages, testing, shared login, analytics, advertising pixels, and presentation materials.

In plain words
What is it for?
Use it for jobs such as drawing Excalidraw diagrams, setting up Google Analytics or Meta Pixel, running user-acceptance testing, creating landing pages, and preparing pitch decks or videos.
Why use it?
It brings many unrelated workflows into one add-on, so the available tasks are described in one place instead of separate packages.

Security

Grade A, and why

ccc-skills 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 3d 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.

Contents

What it installs

The manifest is a name and a version. 15 skills travel with it, and installing the plugin installs all of them — 2,333 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#ccc-skills in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
