CLAUDE.md

agentx CLAUDE.md is an instructions file for Claude Code from agentsdance/agentx. It costs 623 tokens per session, scanned B, original, Apache-2.0.

A project instruction file for AgentX, a command-line tool that manages servers, skills, and plugins for several AI coding agents.

In plain words
What is it for?
It helps build and test AgentX, run its terminal interface and commands, understand its code layers, and avoid committing or pushing changes.
Why use it?
It gives agents the commands, architecture, testing steps, and Git restrictions needed to work correctly in the repository.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is agentsdance/agentx's own configuration. It tells Claude Code how to work on agentx 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 agentx 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 B, and why

agentx CLAUDE.md scanned grade B 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 2mo 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 directoriesmediumAgent snooping

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

Git Operations

Never run git commit or git push - the user handles all git operations manually.

Architecture

AgentX is a CLI tool for managing MCP servers, skills, and plugins across multiple AI coding agents (Claude Code, Codex, Cursor, Gemini CLI, OpenCode).

Core Layers

CLI Layer (cmd/): Cobra-based commands. root.go launches the TUI when run without arguments, or delegates to subcommands (install, check, list, remove, skills, plugins).

Agent Abstraction (internal/agent/): The Agent interface defines operations for all supported agents. Each agent (Claude, Codex, Cursor, Gemini, OpenCode) implements this interface with its own config file location and format:

  • Claude Code: ~/.claude.json
  • Codex: ~/.codex/config.toml
  • Cursor: ~/.cursor/mcp.json
  • Gemini CLI: ~/.gemini/settings.json
  • OpenCode: ~/.opencode/config.json

Domain Logic (internal/):

  • skills/: Skill installation from local paths or Git repos, YAML frontmatter parsing
  • plugins/: Plugin management with remote registry fetch and local caching
  • config/: JSON config file reading/writing for agent configurations
  • mcp/: MCP server definitions (Playwright, Context7)

TUI Layer (ui/): Built with Bubble Tea and Lip Gloss.

  • app.go: Main model coordinating views, tabs, header, sidebar, and footer
  • views/: Four tab views (MCP, Skills, Plugins, Agents) - each implements the View interface
  • components/: Reusable UI pieces (TabBar, Header, Sidebar, Footer)
  • theme/: Color scheme and styling

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.
