# Sandbox vs Tool Policy vs Elevated

KaijiBot has three related (but different) controls:

1. **Sandbox** (`agents.defaults.sandbox.*` / `agents.list[].sandbox.*`) decides **where tools run** (Docker vs host).
2. **Tool policy** (`tools.*`, `tools.sandbox.tools.*`, `agents.list[].tools.*`) decides **which tools are available/allowed**.
3. **Elevated** (`tools.elevated.*`, `agents.list[].tools.elevated.*`) is an **exec-only escape hatch** to run outside the sandbox when you’re sandboxed (`gateway` by default, or `node` when the exec target is configured to `node`).

## Quick debug

Use the inspector to see what KaijiBot is _actually_ doing:

```bash
kaijibot sandbox explain
kaijibot sandbox explain --session agent:main:main
kaijibot sandbox explain --agent work
kaijibot sandbox explain --json
```

It prints:

- effective sandbox mode/scope/workspace access
- whether the session is currently sandboxed (main vs non-main)
- effective sandbox tool allow/deny (and whether it came from agent/global/default)
- elevated gates and fix-it key paths

## Sandbox: where tools run

Sandboxing is controlled by `agents.defaults.sandbox.mode`:

- `"off"`: everything runs on the host.
- `"non-main"`: only non-main sessions are sandboxed (common “surprise” for groups/channels).
- `"all"`: everything is sandboxed.

See [Sandboxing](/gateway/sandboxing) for the full matrix (scope, workspace mounts, images).

### Bind mounts (security quick check)

- `docker.binds` _pierces_ the sandbox filesystem: whatever you mount is visible inside the container with the mode you set (`:ro` or `:rw`).
- Default is read-write if you omit the mode; prefer `:ro` for source/secrets.
- `scope: "shared"` ignores per-agent binds (only global binds apply).
- KaijiBot validates bind sources twice: first on the normalized source path, then again after resolving through the deepest existing ancestor. Symlink-parent escapes do not bypass blocked-path or allowed-root checks.
- Non-existent leaf paths are still checked safely. If `/workspace/alias-out/new-file` resolves through a symlinked parent to a blocked path or outside the configured allowed roots, the bind is rejected.
- Binding `/var/run/docker.sock` effectively hands host control to the sandbox; only do this intentionally.
- Workspace access (`workspaceAccess: "ro"`/`"rw"`) is independent of bind modes.

## Tool policy: which tools exist/are callable

Two layers matter:

- **Tool profile**: `tools.profile` and `agents.list[].tools.profile` (base allowlist)
- **Provider tool profile**: `tools.byProvider[provider].profile` and `agents.list[].tools.byProvider[provider].profile`
- **Global/per-agent tool policy**: `tools.allow`/`tools.deny` and `agents.list[].tools.allow`/`agents.list[].tools.deny`
- **Provider tool policy**: `tools.byProvider[provider].allow/deny` and `agents.list[].tools.byProvider[provider].allow/deny`
- **Sandbox tool policy** (only applies when sandboxed): `tools.sandbox.tools.allow`/`tools.sandbox.tools.deny` and `agents.list[].tools.sandbox.tools.*`

Rules of thumb:

- `deny` always wins.
- If `allow` is non-empty, everything else is treated as blocked.
- Tool policy is the hard stop: `/exec` cannot override a denied `exec` tool.
- `/exec` only changes session defaults for authorized senders; it does not grant tool access.
  Provider tool keys accept either `provider` (e.g. `google-antigravity`) or `provider/model` (e.g. `openai/gpt-5.4`).

### Tool groups (shorthands)

Tool policies (global, agent, sandbox) support `group:*` entries that expand to multiple tools:

```json5
{
  tools: {
    sandbox: {
      tools: {
        allow: ["group:runtime", "group:fs", "group:sessions", "group:memory"],
      },
    },
  },
}
```

Available groups:

- `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`, `video_generate`, `tts`
- `group:kaijibot`: all built-in KaijiBot tools (excludes provider plugins)

## Elevated: exec-only "run on host"

Elevated does **not** grant extra tools; it only affects `exec`.

- If you’re sandboxed, `/elevated on` (or `exec` with `elevated: true`) runs outside the sandbox (approvals may still apply).
- Use `/elevated full` to skip exec approvals for the session.
- If you’re already running direct, elevated is effectively a no-op (still gated).
- Elevated is **not** skill-scoped and does **not** override tool allow/deny.
- Elevated does not grant arbitrary cross-host overrides from `host=auto`; it follows the normal exec target rules and only preserves `node` when the configured/session target is already `node`.
- `/exec` is separate from elevated. It only adjusts per-session exec defaults for authorized senders.

Gates:

- Enablement: `tools.elevated.enabled` (and optionally `agents.list[].tools.elevated.enabled`)
- Sender allowlists: `tools.elevated.allowFrom.<provider>` (and optionally `agents.list[].tools.elevated.allowFrom.<provider>`)

See [Elevated Mode](/tools/elevated).

## Common "sandbox jail" fixes

### "Tool X blocked by sandbox tool policy"

Fix-it keys (pick one):

- Disable sandbox: `agents.defaults.sandbox.mode=off` (or per-agent `agents.list[].sandbox.mode=off`)
- Allow the tool inside sandbox:
  - remove it from `tools.sandbox.tools.deny` (or per-agent `agents.list[].tools.sandbox.tools.deny`)
  - or add it to `tools.sandbox.tools.allow` (or per-agent allow)

### "I thought this was main, why is it sandboxed?"

In `"non-main"` mode, group/channel keys are _not_ main. Use the main session key (shown by `sandbox explain`) or switch mode to `"off"`.
