A command-line connection between an AI assistant and the Unity Editor or a running Unity game. Unity is a tool for building games and interactive 3D applications.

Checking compilation and logs, finding or editing assets, scenes, prefabs, and Inspector values, taking screenshots, and sending input during Play Mode.

It lets you inspect and operate Unity projects through commands instead of relying only on the Unity interface.

Per session 79 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 435 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.00435
Opus 5	$0.00039	$0.00217
Sonnet 5	$0.00016	$0.00087
Haiku 4.5	$0.00008	$0.00044

Security

Grade A, and why

aibridge scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AI Bridge Unity Skill

Invocation

Run from Unity project root. $CLI is the platform AIBridge CLI; on Windows PowerShell prefer:

& "./.aibridge/cli/AIBridgeCLI.exe" <command> [action] [options]

Common options: --timeout, --raw, --pretty, --json, --stdin, --help, --on-dialog. Installed command references live under references/ after Skill install

Harness Snapshot

Project-side capabilities are in Root Rule / workflow rules. $CLI harness status is optional diagnosis only — not enablement/freshness preflight

Operating Rules

Unity validation: compile unity. compile dotnet is an extra check, not a Unity fallback
Imported asset path discovery: asset search/find --format paths when Editor is available
Edit order: inspector set_property/set_properties → aibridge-prefab-patch → Editor scripts → unity-yaml-editing only for unsupported YAML structure
Prefab asset edits: assetPath + objectPath + componentName/componentIndex; componentInstanceId is scene-only
focus Windows-only; dialog CLI-only; input needs Play Mode + EventSystem
runtime: quick list_targets first; --probe true only for port scan; UI start with runtime.ui.snapshot
Code Index: only when Root Rule declares enabled — load aibridge-code-index for declaration-name lookup
Do not proactively clean .aibridge cache unless the user asks for maintenance

Files

What ships with it

33 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
