AI Bridge Unity Skill

Invocation

Run commands from the Unity project root.

CLI Path: ./.aibridge/cli/AIBridgeCLI.exe

Example Alias: $CLI is a shorthand for the platform-appropriate AIBridge CLI invocation. Examples use $CLI for consistency; replace it with the matching invocation form when running commands directly.

Invocation Forms:

• Windows executable: ./.aibridge/cli/AIBridgeCLI.exe <command> [action] [options]
• macOS/Linux DLL: dotnet ./.aibridge/cli/AIBridgeCLI.dll <command> [action] [options]
• PowerShell call operator: & "./.aibridge/cli/AIBridgeCLI.exe" <command> [action] [options]

Most Unity-side commands require an action such as asset search or inspector set_property. CLI-only commands and helpers can differ: focus has no action, dialog uses status/click/wait, and multi uses --cmd or --stdin. Use --help or the generated command reference for the exact form.

Global Options:

• --timeout <ms> - Timeout (default: 5000)
• --on-dialog <mode> - When a Unity command is blocked by a modal dialog, optionally wait or click: none, wait, cancel, save, discard, ok, yes, no, delete, replace
• --raw / --pretty - JSON output (default: raw)
• --json <json> / --stdin - Complex parameters
• --help - Show help

Cache Directory: .aibridge/ (Editor commands/results/screenshots and Runtime targets under .aibridge/runtime/targets/)

Dialog Output Rule: dialog status omits blockedByDialog and dialogs when no blocking Unity modal dialog is detected. Missing fields mean no dialog.

Operating Rules

• Use compile unity for Unity validation. compile dotnet is an explicit extra solution-build check, not a fallback.
• For Unity assets, prefer asset search/find --format paths; use host file reads for file contents, and asset read_text only when host reads are unavailable.
• Resource edit order: use inspector set_property/set_properties for single or batched fields, aibridge-prefab-patch for complex Prefab structure edits it supports, Unity Editor scripts for high-level generated assets, and unity-yaml-editing only for unsupported serialized-file structure work.
• For scene objects, Prefabs, and serialized Unity assets, discover targets with inspector get_components/get_properties/find_property, then write with AIBridge/Unity APIs when possible; avoid raw YAML unless no supported API can express the operation.
• Direct YAML edits are acceptable only after loading unity-yaml-editing, including unsupported Scene/Prefab/ScriptableObjectTable/custom .asset operations. Preserve m_Script, fileID/guid/type references, YAML indentation, and paired .meta GUIDs; validate afterward with import, targeted inspection, compile unity, and Error logs.
• For prefab asset edits, use assetPath + objectPath + componentName or componentIndex; componentInstanceId is scene-only.
• For complex prefab asset edits, use the aibridge-prefab-patch skill and prefer prefab patch --ops <file> with dry-run first.
• In PowerShell, avoid inline complex --json; build JSON in a variable, escape embedded quotes for native EXE argument passing, and pass command parameters directly, especially inspector set_properties --values $values.
• focus is Windows CLI-only. dialog is CLI-only, uses Windows window APIs or macOS Accessibility permission, and omits dialog fields when no modal dialog is detected. screenshot game and screenshot gif require Play Mode; screenshot scene_view works in Edit mode when a Scene view is open.
• input requires Play Mode and an active EventSystem; use it with gameview, screenshot, and get_logs for UI interaction checks.
• runtime is CLI-only and talks to AIBridgeRuntime inside a Player or Play Mode target. Use runtime list_targets first, then target latest or a specific target id.
• Code Index is a separate optional Skill. Use aibridge-code-index only when that Skill is installed and project rules say Code Index is enabled; otherwise use rg, file reads, and regular AIBridge commands.

Essential Commands

focus - Bring Unity to Foreground

CLI-only, Windows-only. Triggers Unity refresh/compile via Windows API.

bashCopy code
$CLI focus
# Output: {"Success":true,"ProcessId":1234,"WindowTitle":"MyProject - Unity 6000.0.51f1","Error":null}

dialog - Inspect Or Click Unity Modal Dialogs

CLI-only. Use when a save/confirm modal may be blocking the Editor. Unity commands report detected dialog details instead of blindly waiting; choose an explicit dialog click or use --on-dialog for unattended handling.

bashCopy code
$CLI dialog status
$CLI dialog click --choice cancel
$CLI dialog click --button "Don't Save"
$CLI dialog wait --timeout 5000 --click cancel
$CLI scene load --scenePath Assets/Main.unity --on-dialog cancel

multi - Execute Multiple Commands (Recommended)

Use aibridge-batch-script before writing long scripts or JSON-heavy multi --stdin commands.

bashCopy code
$CLI multi --cmd 'editor log --message Step1&gameobject create --name Cube --primitiveType Cube'
$CLI multi --stdin

In batch/multi scripts, dialog click ok | yes | Save declares persistent dialog auto-click choices for subsequent steps; a later dialog click replaces the previous strategy. Keep the CLI invocation waiting, because --no-wait exits before it can continue clicking.

input - Runtime Input Simulation

Play Mode only. Use the generated command reference for all actions and parameters.

bashCopy code
$CLI input click --path "Canvas/StartButton"
$CLI input drag --path "Canvas/Item" --toPath "Canvas/Slot" --frames 12

runtime - Built Player Runtime Bridge

Requires an AIBridgeRuntime component in the running Player or Play Mode scene. HTTP is the default Runtime transport; if the default HTTP port is occupied, Runtime auto-increments and writes the actual URL to the live heartbeat. LAN discovery also auto-increments from the default UDP port, and CLI defaults scan the local HTTP/discovery port ranges so multiple local Editors or built Players can be discovered. File transport remains available for Editor/local compatibility. Configure defaults in AIBridge/Settings > Runtime, and inspect live targets plus discovery cache in AIBridge/Players.

bashCopy code
$CLI runtime list_targets
$CLI runtime status --target latest
$CLI runtime discover
$CLI runtime diagnose --target latest
$CLI runtime logs --target latest --logType Error --count 100
$CLI runtime perf --target latest --duration 5s --interval 100ms
$CLI runtime screenshot --target latest
$CLI runtime handlers --target latest
$CLI runtime call --target latest --action qa.open_panel --json "{\"panel\":\"Inventory\"}"

For multiple local Players, run $CLI runtime list_targets first and pass a specific target id such as $CLI runtime status --target AIBridgeDev_12345. $CLI runtime diagnose --target <id> diagnoses that target's resolved HTTP URL.

For remote phones, run $CLI runtime discover on the LAN first, then target the discovered id or URL. On Android USB, run adb reverse tcp:27182 tcp:27182 first, then call --transport http --url http://127.0.0.1:27182; adb is not a runtime transport mode.
