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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00065 | $0.01687 |
| Opus 5 | $0.00032 | $0.00843 |
| Sonnet 5 | $0.00013 | $0.00337 |
| Haiku 4.5 | $0.00006 | $0.00169 |
Grade A, and why
build-godot-game 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 12d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a Godot game
Build the smallest coherent playable loop and prove it independently. Godot Agent Loop supports Godot 4.7 or later. Report an older project or engine as outside the supported boundary. Never add MCP autoloads, addons, or bridge files.
Control contract
- Validate the requested
projectPathagainst the effective MCP roots and allowed directories before mutation. Author project files with normal host file tools:.tscn,.gd, andproject.godotare plain text. Ifproject.godotis absent, create the scaffold with the host's file tools. If Godot is unavailable, stop without writing anything. - Record an acceptance contract before choosing nodes: playable loop, controls, visible feedback, ordinary state, success/failure transitions, and whether the user requested watched or unattended work.
- For watched work, call
editor_sessionwith ensure and launch enabled and route scene edits througheditor_transaction. Stop with a blocker if a matching usable editor cannot be attached or launched; never silently continue detached. Unattended work may author directly with host file tools. - Treat scene, resource, script, and settings edits as persistent authoring.
Treat
game_*observations and injected input as runtime-ephemeral and never report them as saved project changes. - Use canonical core tools directly (compact is only the compatibility alias).
Resolve hidden tools through
godot_catalogdetail, then invoke them withgodot_call; never call a hidden tool directly. - If the human selects Pause Agent, do not retry, route around, or disguise a blocked mutation. Preserve state, continue only safe observation or teardown, and report the blocked effective tool.
- Action schemas are strict:
editor_sessiontimeoutSeconds/launchIfNeeded only apply to ensure; status/disconnect use only projectPath/action.run_project_testsdiscover uses framework/testPaths;stop_projecttakes no arguments.
Workflow
What ships with it
1 file 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.
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.

build-godot-game is a skill published in the GitHub repository beremaran/godot-agent-loop (5 stars, last pushed 2d ago), licensed MIT. It adds 65 tokens to every session and 1,687 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
