Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the cc-suite plugin — 13 skills, 39 commands, 4 agents, 3 hooks shipped together

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

claude-code-conventions scanned grade A with 1 finding 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.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- `~/.claude/settings.json` — global user settings

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Claude Code Plugin Conventions Reference

Purpose: This skill is the single source of truth for Claude Code artifact conventions. Audit commands inject this content into Codex's developer-instructions so Codex can accurately validate Claude Code artifacts despite having no native knowledge of the platform.

Freshness: Last updated 2026-03-25 from context7 (/websites/code_claude_en_plugins-reference, /websites/code_claude_en_plugins). Run /cc-suite:refresh-knowledge to refresh.

When to Use

Load this skill when:

  • Auditing Claude Code plugin artifacts (commands, agents, skills, hooks, plugin.json)
  • Validating frontmatter fields against the official schema
  • Checking hook event names, types, and output formats
  • Authoring new plugin artifacts and need the canonical field reference
  • Running /cc-suite:audit-plugin, /cc-suite:audit-command, /cc-suite:audit-agent, or /cc-suite:audit-skill

plugin.json Schema

Only name is strictly required. Version and description are strongly recommended but optional.

Required:

  • name (string): plugin identifier, kebab-case. Used for namespacing (e.g., plugin-dev:agent-creator)

Recommended:

  • version (string): semver X.Y.Z. If also set in marketplace entry, plugin.json takes precedence
  • description (string): brief purpose

Optional metadata:

  • author (object): { "name": "string", "email": "string", "url": "string" }
  • homepage (string): URL to plugin docs
  • repository (string): URL to source code
  • license (string): SPDX identifier (e.g., "MIT", "Apache-2.0")
  • keywords (string[]): discovery tags

Component path fields (string, string[], or inline object):

  • commands — path(s) to command files. Default: ./commands/ (auto-discovered)
  • agents — path(s) to agent files. Default: ./agents/ (auto-discovered)
  • skills — path(s) to skill directories. Default: ./skills/ (auto-discovered)
  • hooks — path to hooks config OR inline hooks object. Default: ./hooks/hooks.json
  • mcpServers — path to MCP config OR inline object. Default: ./.mcp.json
  • lspServers — path to LSP config. Default: ./.lsp.json
  • outputStyles — path to output style definitions

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.
