Special Skills
**Graph engineering and bounded-behavior plugins for coding agents.**
Special Skills is a maintained collection of agent plugins for Claude Code, Codex, and any agent that reads the [Agent Skills](https://agentskills.io) format. Every package makes agent behavior more reliable, bounded, inspectable, or repeatable, and every claim of that kind is backed by something you can run: a hook, a validator, a test, or an eval.
Start here
| If you want to | Install |
|---|---|
| Decide whether a workflow needs a graph at all, then design, validate, compile, audit, or evolve one as a versioned artifact | `graph-engineering` |
| Stop an agent from looping on the same failed fix and force an evidence-backed handoff | `anti-loop` |
| Get a receipt after every change and a verification gate before "done" | `cleancoding` |
| Treat fetched pages, files, and tool output as data instead of instructions | `untrusted-content` |
`graph-engineering` covers execution graphs: agents, tools, typed state, edges, checkpoints, and approvals as one validated artifact. It is not a knowledge-graph or GraphRAG tool; it says so and routes those requests elsewhere.
Install
Any agent that supports Agent Skills (Claude Code, Codex, Cursor, Copilot, Gemini CLI, and others):
npx skills add MTEnt/special-skills --skill graph-engineeringPlugins that ship lifecycle hooks (`cleancoding`, `anti-loop`, `anti-amnesia`, `temporal-tasks`) need the plugin route so the hooks install with the skill. Add the marketplace once, then install what you need.
Claude Code:
/plugin marketplace add MTEnt/special-skills
/plugin install graph-engineering@special-skillsCodex:
codex plugin marketplace add MTEnt/special-skills
codex plugin add graph-engineering@special-skillsEvery plugin installs the same way; substitute the name from the t
