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 | $0.00374 | $0.00374 |
| Opus 5.5 | $0.00150 | $0.00150 |
| Sonnet 5.5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
claude-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 1mo 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.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What This Repo Is
A Claude Code plugin marketplace hosting multiple plugins under plugins/.
Repo Structure
.claude-plugin/marketplace.json — marketplace manifest (lists all plugins)
plugins/<plugin>/.claude-plugin/plugin.json — per-plugin manifest
plugins/<plugin>/skills/<skill>/SKILL.md — skill definition (YAML frontmatter + instructions)
plugins/<plugin>/skills/<skill>/*.{sh,py} — companion scripts referenced by the skill
Skills are invoked as /<plugin>:<skill>. Testing locally: claude --plugin-dir plugins/<plugin>
Releasing a New Version
When bumping a plugin's version, update both declarations:
plugins/<plugin>/.claude-plugin/plugin.json—versionfield.claude-plugin/marketplace.json—versionin the plugin entry underplugins[]
Versions for the same plugin MUST match across both files.
Current Plugins
- serena-setup (
/serena-setup:serena-setup) — Copies.serena/from main repo to worktree and installs apost-checkouthook for automatic setup of future worktrees - jdtls-lombok-fix — Auto-triggered skill that patches the
jdtls-lspplugin'smarketplace.jsonto pass-javaagent:lombok.jarto JDTLS, removing the flood of false-positive Lombok errors (log cannot be resolved,builder() undefined, etc.). Background: anthropics/claude-plugins-official#1000
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.

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