# agentskills

> A personal directory of AI coding agents, agent skills, plugins, and MCP servers. Short factual entries — no marketing language.

Source of truth is structured data under `lib/data/` (TypeScript).
These files are generated for AI agents — prefer Markdown links below over scraping HTML.

## Optional

- [Full directory dump](/llms-full.txt): every entry as Markdown in one file
- [About](/about): why this list is hand-kept (not a marketplace)

## Tools

- [Claude Code](/tools/claude-code.md): Anthropic's coding agent in the terminal — reads the repo, edits files, runs commands, and works with git.
- [Codex](/tools/codex.md): OpenAI's open-source coding agent — runs in the terminal, with IDE, desktop, and cloud surfaces.
- [Cursor](/tools/cursor.md): An AI-first code editor, forked from VS Code.

- [herdr](/tools/herdr.md): Terminal multiplexer for coding agents — panes, detach, and multi-agent sessions.
- [Open Code Review](/tools/open-code-review.md): CLI for LLM code review with line-level comments, rules, and agent integrations.
- [Headroom](/tools/headroom.md): Compresses tool outputs and context before they reach the LLM (library, proxy, MCP).
