# pixi.tree.select

Selects the node (sets window.$pixi) and draws the selection overlay on the canvas. The user can silence that overlay from the panel (the eye button above the tree); selection itself still works, nothing is painted.

| --- | --- | --- | --- |
| `id` | string | yes | Stable node id from the tree |
| `tabId` | integer | no | Legacy: a bare tab id, resolved inside the browser this session is already working with. Prefer `target`, which is unambiguous across browsers. |
| `target` | string | no | Drive a specific tab: a target id like "b7a3c1#487" from status/use_target/CHOOSE_TARGET. Omit to use this session's chosen tab (or the only available one). Pas |
| `frameId` | integer | no | Escape hatch: drive a specific FRAME of the tab (0 is the top frame). Normally unnecessary — the extension picks the frame running the game (canvas owner first, |

## Why pixi.tree.select is rated Low

Without any rule in front of it, every call an agent makes to pixi.tree.select happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

## Use case

AI agents call pixi.tree.select as a supporting operation in Pixi Inspector workflows.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pixi Inspector:

```json

    "pixi.tree.select": {
      "limits": [
        {
