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.

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 | $0.00083 | $0.01261 |
| Opus 5 | $0.00042 | $0.00630 |
| Sonnet 5 | $0.00017 | $0.00252 |
| Haiku 4.5 | $0.00008 | $0.00126 |
Grade A, and why
bevy-cargo-features 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 11d 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bevy 0.19 — Cargo features
When to use this skill
- Choose a supported application profile without enabling the full default set.
- Compose a custom renderer or a headless server.
- Enable native controller input, window/input APIs, or browser rendering.
- Diagnose types/plugins missing after disabling default features.
Canonical profiles
Bevy's default is 2d + 3d + ui + audio. To select a profile, disabling
defaults is essential:
# 3D game with Bevy UI, but no audio or 2D renderer
bevy = { version = "0.19", default-features = false, features = ["3d", "ui"] }
# 2D game with audio, but no 3D renderer or UI
# bevy = { version = "0.19", default-features = false, features = ["2d", "audio"] }
Writing features = ["3d"] while leaving default features enabled does not
trim anything: Cargo unions feature sets.
Collection layers
| Layer | Features | Meaning |
|---|---|---|
| Profiles | 2d, 3d, ui, audio |
Complete app shapes |
| Built-in render | 2d_bevy_render, 3d_bevy_render, ui_bevy_render |
Bevy's renderer for one domain |
| API only | 2d_api, 3d_api, ui_api |
Components/assets without a render backend |
| Baseline | default_app, default_platform |
Core app services vs platform/window/input services |
| Grouped | scene, picking, dev |
Related feature collections |
API-only features cannot draw. They are for custom/external renderers that consume Bevy's world-side types.
Headless server
bevy = { version = "0.19", default-features = false, features = [
"default_app",
"multi_threaded",
"serialize",
"bevy_world_serialization", # omit if the server never loads saved worlds
] }
Use MinimalPlugins, then add only the service plugins the server needs.
bevy_scene is BSN in 0.19; classic reflected world serialization is
bevy_world_serialization.
Custom renderer
bevy = { version = "0.19", default-features = false, features = [
"default_app",
"3d_api",
] }
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.

bevy-cargo-features is a skill published in the GitHub repository chrisgliddon/bevy-skills (12 stars, last pushed 16d ago), licensed MIT. It adds 83 tokens to every session and 1,261 once invoked, about $0.0004 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.

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…

Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
