# Plugins

> Built-in add-ons you connect to an agent with an arrow — no restart, no changes to your CLI's own settings.

A plugin changes how a connected agent works. You add it from the add-card menu — **Plugin…** opens
the **Plugins** tab of the catalog, where you search and pick one — and connect it to an agent with
an [arrow](https://docs.neurosquad.ai/en/canvas/arrows). The agent picks it up on its next action; remove the arrow and it stops.

Plugins ship with NeuroSquad and are checked before they get into the list. Your CLI's own settings
are never changed: a plugin is a layer NeuroSquad adds to that one agent card.

  - **[RTK-AI Token Saver](https://docs.neurosquad.ai/en/plugins/rtk-ai-token-saver)**: Compresses the output of an agent's shell commands — fewer tokens, same facts.
  - **[Caveman](https://docs.neurosquad.ai/en/plugins/caveman)**: Makes the agent's answers short — no filler, code and errors kept exact.
  - **[Memory (mem0)](https://docs.neurosquad.ai/en/plugins/mem0-memory)**: Long-term memory your agents share across sessions — kept on your computer.
  - **[Context7 — up-to-date docs](https://docs.neurosquad.ai/en/plugins/context7-docs)**: Current, version-specific library docs for your agents instead of stale training data.
  - **[Code Graph](https://docs.neurosquad.ai/en/plugins/code-graph)**: A knowledge graph of your code — agents find callers, callees and definitions instead of grepping.
  - **[Graphify](https://docs.neurosquad.ai/en/plugins/graphify)**: A live map of your code — agents ask it structural questions, and every query lights up on the map.

More plugins are on the way. Skills and MCP servers work the same way through their own tabs of the
catalog — see [Skills & MCP](https://docs.neurosquad.ai/en/skills-mcp).
