## Rexa skills

Rexa links two skills into every supported agent. They only run inside a Rexa terminal.

| Skill     | What it teaches the agent                                                      |
| --------- | ------------------------------------------------------------------------------ |
| browser   | Drive a Rexa browser tab with [`rexa web`](/docs/reference/rexa-web): open, snapshot, act, wait, check. |
| handoff   | Pass work to another live agent with `rexa agent send`, as a reviewer and worker loop of up to three rounds. |

Each agent names them its own way:

| Agent        | Browser skill          | Handoff skill          |
| ------------ | ---------------------- | ---------------------- |
| Claude Code  | `/rexa:browser`        | `/rexa:handoff`        |
| Codex        | `$rexa:browser`        | `$rexa:handoff`        |
| Cursor Agent | `/rexa-browser`        | `/rexa-handoff`        |
| OpenCode     | `rexa-browser`         | `rexa-handoff`         |
| Pi           | `/skill:rexa-browser`  | `/skill:rexa-handoff`  |

Agents also pick a skill on their own when the task matches it, such as "check the page in the browser".

## Session context

When an agent starts in a Rexa terminal, a hook gives it a short note: it runs in Rexa, and can use `rexa web`, `rexa sessions`, `rexa lsp`, `rexa pty ls` and `rexa extension ls`. Outside Rexa the hook adds nothing.

## Manage skills, plugins and MCP servers

Open the Agents panel (<Kbd>⌘</Kbd> <Kbd>⇧</Kbd> <Kbd>A</Kbd>) and click an agent. Its manage tab lists what the agent loads, in tabs: MCPs, Memories, Skills, Commands, Hooks and Config. Filter by **All** or **Enabled**, or search.

For Claude Code and Codex, the tab has switches:

| Agent       | You can toggle              | Written to                                                                 |
| ----------- | --------------------------- | -------------------------------------------------------------------------- |
| Claude Code | Skills, commands, plugins   | `~/.claude/settings.json`, or the worktree's `.claude/settings.json` or `.claude/settings.local.json` |
| Codex       | Skills, plugins, MCP servers | `~/.codex/config.toml`                                                    |

Each switch shows which file decides it, with **Unset**, **On** or **Off** per file. Entries set by a file Rexa does not write, such as a managed policy, are marked and read-only. Cursor Agent, OpenCode and Pi show their lists read-only.

The tab rereads when the agent's config files change.
