Instructions file for Claude Code

Written for Claude Code: Claude Code plugin machinery. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions Claude Code.

This is Quant-Off/skills's own configuration. It tells Claude Code how to work on skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skills configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

skills 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.

CLAUDE.md

Directives for Claude Code when working in this repository. Follow these rules whenever you create or modify files here. The human contribution workflow lives in CONTRIBUTING.md; this file is the operating manual for the agent.

Repository context

Quant-Off/skills is a Claude Code plugin marketplace for security research. Each plugin bundles one or more skills that let Claude Code verify cryptographic code, analyze binary artifacts with Ghidra, and audit codebases accurately and repeatably.

Structural rules (never violate)

  • .claude-plugin/marketplace.json lives at the repo root, never inside a plugin.
  • A plugin's plugin.json lives at plugins/<name>/.claude-plugin/plugin.json.
  • Skills, commands, agents, and hooks live at the plugin root (plugins/<name>/skills/...), never inside .claude-plugin/.
  • Skills auto-discover from the plugin's skills/ directory; no extra declaration is needed unless a custom path is used.

Marketplace facts

  • The marketplace name is quant-security (from marketplace.json).
  • Each plugin's source is a repo-relative path (./plugins/<name>), so everything ships from this single repository.
  • Install path for users: /plugin marketplace add Quant-Off/skills then /plugin install <plugin-name>@quant-security.

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.
