# Tools and Plugins

Everything the agent does beyond generating text happens through **tools**.
Tools are how the agent reads files, runs commands, browses the web, sends
messages, and interacts with devices.

## Tools, skills, and plugins

KaijiBot has three layers that work together:

<Steps>
  <Step title="Tools are what the agent calls">
    A tool is a typed function the agent can invoke (e.g. `exec`, `browser`,
    `web_search`, `message`). KaijiBot ships a set of **built-in tools** and
    plugins can register additional ones.

    The agent sees tools as structured function definitions sent to the model API.

  </Step>

  <Step title="Skills teach the agent when and how">
    A skill is a markdown file (`SKILL.md`) injected into the system prompt.
    Skills give the agent context, constraints, and step-by-step guidance for
    using tools effectively. Skills live in your workspace, in shared folders,
    or ship inside plugins.

    [Skills reference](/tools/skills) | [Creating skills](/tools/creating-skills)

  </Step>

  <Step title="Plugins package everything together">
    A plugin is a package that can register any combination of capabilities:
    channels, model providers, tools, skills, speech, realtime transcription,
    realtime voice, media understanding, image generation, video generation,
    web fetch, web search, and more. Some plugins are **core** (shipped with
    KaijiBot), others are **external** (published on npm by the community).

## Built-in tools

These tools ship with KaijiBot and are available without installing any plugins:

| `session_status`                           | Lightweight `/status`-style readback and session model override       | [Session Tools](/concepts/session-tool)     |

For image work, use `image` for analysis and `image_generate` for generation or editing. If you target `openai/*`, `google/*`, `fal/*`, or another non-default image provider, configure that provider's auth/API key first.

For music work, use `music_generate`. If you target `google/*`, `minimax/*`, or another non-default music provider, configure that provider's auth/API key first.

For video work, use `video_generate`. If you target `qwen/*` or another non-default video provider, configure that provider's auth/API key first.

For workflow-driven audio generation, use `music_generate` when a plugin such as
ComfyUI registers it. This is separate from `tts`, which is text-to-speech.

`session_status` is the lightweight status/readback tool in the sessions group.
It answers `/status`-style questions about the current session and can
optionally set a per-session model override; `model=default` clears that
override. Like `/status`, it can backfill sparse token/cache counters and the
active runtime model label from the latest transcript usage entry.

`gateway` is the owner-only runtime tool for gateway operations:

- `config.schema.lookup` for one path-scoped config subtree before edits
- `config.get` for the current config snapshot + hash
- `config.patch` for partial config updates with restart
- `config.apply` only for full-config replacement
- `update.run` for explicit self-update + restart

For partial changes, prefer `config.schema.lookup` then `config.patch`. Use
`config.apply` only when you intentionally replace the entire config.
The tool also refuses to change `tools.exec.ask` or `tools.exec.security`;
legacy `tools.bash.*` aliases normalize to the same protected exec paths.

### Plugin-provided tools

Plugins can register additional tools. Some examples:

- [Lobster](/tools/lobster) — typed workflow runtime with resumable approvals
- [LLM Task](/tools/llm-task) — JSON-only LLM step for structured output
- [Music Generation](/tools/music-generation) — shared `music_generate` tool with workflow-backed providers
- [Diffs](/tools/diffs) — diff viewer and renderer
- [OpenProse](/prose) — markdown-first workflow orchestration

## Tool configuration

### Allow and deny lists

Control which tools the agent can call via `tools.allow` / `tools.deny` in
config. Deny always wins over allow.

```json5
{
  tools: {
    allow: ["group:fs", "browser", "web_search"],
    deny: ["exec"],
  },
}
```

### Tool profiles

`tools.profile` sets a base allowlist before `allow`/`deny` is applied.
Per-agent override: `agents.list[].tools.profile`.

| Profile     | What it includes                                                                                                                                  |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
| `full`      | No restriction (same as unset)                                                                                                                    |
| `coding`    | `group:fs`, `group:runtime`, `group:web`, `group:sessions`, `group:memory`, `cron`, `image`, `image_generate`, `music_generate`, `video_generate` |
| `messaging` | `group:messaging`, `sessions_list`, `sessions_history`, `sessions_send`, `session_status`                                                         |
| `minimal`   | `session_status` only                                                                                                                             |

### Tool groups

Use `group:*` shorthands in allow/deny lists:

| Group              | Tools                                                                                                     |
| ------------------ | --------------------------------------------------------------------------------------------------------- |
| `group:runtime`    | exec, process, code_execution (`bash` is accepted as an alias for `exec`)                                 |
| `group:fs`         | read, write, edit, apply_patch                                                                            |
| `group:sessions`   | sessions_list, sessions_history, sessions_send, sessions_spawn, sessions_yield, subagents, session_status |
| `group:memory`     | memory_search, memory_get                                                                                 |
| `group:web`        | web_search, x_search, web_fetch                                                                           |
| `group:ui`         | browser, canvas                                                                                           |
| `group:automation` | cron, gateway                                                                                             |
| `group:messaging`  | message                                                                                                   |
| `group:nodes`      | nodes                                                                                                     |
| `group:agents`     | agents_list                                                                                               |
| `group:media`      | image, image_generate, music_generate, video_generate, tts                                                |
| `group:kaijibot`   | All built-in KaijiBot tools (excludes plugin tools)                                                       |

`sessions_history` returns a bounded, safety-filtered recall view. It strips
thinking tags, `<relevant-memories>` scaffolding, plain-text tool-call XML
payloads (including `<tool_call>...</tool_call>`,
`<function_call>...</function_call>`, `<tool_calls>...</tool_calls>`,
`<function_calls>...</function_calls>`, and truncated tool-call blocks),
downgraded tool-call scaffolding, leaked ASCII/full-width model control
tokens, and malformed MiniMax tool-call XML from assistant text, then applies
redaction/truncation and possible oversized-row placeholders instead of acting
as a raw transcript dump.

### Provider-specific restrictions

Use `tools.byProvider` to restrict tools for specific providers without
changing global defaults:

```json5
{
  tools: {
    profile: "coding",
    byProvider: {
      "google-antigravity": { profile: "minimal" },
    },
  },
}
```
