Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00420 | $0.00420 |
| Opus 5 | $0.00210 | $0.00210 |
| Sonnet 5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
cc-plugins CLAUDE.md 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 4d 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.
What it actually says
Claude Code Plugin Marketplace
This repo is a Claude Code plugin marketplace owned by Reggie Chan (reggiechan74/cc-plugins).
Plugin README Standards
Install section
Every plugin README must include an ## Installation section with two subsections:
From Marketplace — the primary, end-user form. Required, must be exact:
/plugin marketplace add reggiechan74/cc-plugins
/plugin install <plugin-name>@cc-plugins
Local Development — for contributors testing from a clone of this repo. Required, must be exact:
/plugin marketplace add .
/plugin install <plugin-name>@cc-plugins
(Run after cloning reggiechan74/cc-plugins and cd-ing into the clone. The . registers the local checkout as a marketplace under the same cc-plugins name, so the install command is identical to production.)
Do not use claude plugin add /path/to/..., claude --plugin-dir, cp -r, ln -s, or any other ad-hoc form. Consistency across plugins matters more than per-plugin preference.
Badges
Every plugin README must include shields.io badges inside <!-- badges-start --> / <!-- badges-end --> markers, placed immediately after the # heading. Use /update-badges to generate them. At minimum, include version, license, and Claude Code plugin badges.
plugin.json metadata
Every .claude-plugin/plugin.json must include: name, version, description, author.name (Reggie Chan), license (MIT), repository (https://github.com/reggiechan74/cc-plugins), and homepage (https://github.com/reggiechan74/cc-plugins/tree/main/<plugin-dir>).
Skill frontmatter
SKILL.md files must not include a version: field — it is undocumented in the Claude Code skill spec and silently ignored.
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.

cc-plugins CLAUDE.md is an instructions file published in the GitHub repository reggiechan74/cc-plugins (6 stars, last pushed 3mo ago), licensed MIT.
