TEngine is a Unity framework for building games, providing modules for asynchronous work, hot updates, asset management, configuration tables, and user interfaces. It is for Unity developers and teams making commercial projects across desktop, mobile, web, and WeChat Mini Game targets, with catalogue skills supporting its AI-assisted development workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.01273 |
| Opus 5.5 | $0.00000 | $0.00509 |
| Sonnet 5.5 | $0.00000 | $0.00255 |
| Haiku 4.5 | $0.00000 | $0.00127 |
Grade A, and why
package-manager 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 23d 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.

How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Package Manager commands
These commands query and modify the project's UPM package set (list, search, add, remove, resolve, status) over UnityEditor.PackageManager. Read-only queries block until the registry responds and return synchronously; mutating commands (package_add/package_remove) require confirm=true, support dry_run previews, and are async by default (poll package_status) with an optional wait=true to block until done.
package_list
List packages by scope: installed (default) | available (registry) | all (both). Returns the full result synchronously — available/all block until the registry query completes.
| Parameter | Required | Default | Description |
|---|---|---|---|
scope |
no | installed |
Which packages to list: installed (default) |
include_indirect |
no | true |
Include indirect (transitive) installed dependencies (applies to scope=installed/all). |
offline |
no | false |
For available/all: query the local cache instead of the registry. |
Returns: object
Notes: MainThreadRequired = false. Synchronous — available/all start a registry query and block until it completes (up to a 25s timeout); installed reads the resolved set inline on the main thread.
package_search
Search packages available in the registry. Provide a name (e.g. com.unity.foo) or omit to list all. Returns the full result synchronously (blocks until the registry query completes).
| Parameter | Required | Default | Description |
|---|---|---|---|
query |
no | – |
Package name to search for. Omit/empty to list all available packages. |
offline |
no | false |
Search the local cache only. |
Returns: object
Notes: MainThreadRequired = false. Synchronous — blocks until the registry query completes (up to a 25s timeout). Each result is flagged with whether it is currently installed.
package_add
Add a UPM package by name@version, git URL, or 'file:' local path. Async by default (returns in_progress; poll package_status); pass wait=true to block until added. A recompile/domain reload follows — poll recompile_status. Requires confirm=true; use dry_run to preview.
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.
