What it does

Bevy Commands is an agent skill from nolantait/bevy-starter. Reference for Bevy Commands — spawning/despawning entities, inserting/removing components, custom commands, trait extensions, and testing.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A minimalist starter for bevy and rust. The licence is MIT.

Example prompts

“/bevy-commands”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

#[component(on_add = ...)]
#[component(on_insert = ...)]
#[component(on_discard = ...)]
#[component(on_remove = ...)]
#[component(on_despawn = ...)]

What it can do on your machine

Read from SKILL.md and the folder at commit dd6f56b. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are rust).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bevy Commands loads about 783 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 141 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~783

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Basics

Commands is a system parameter that queues mutations into a CommandQueue. Bevy applies them at a sync point: an ApplyDeferred system inserted after command-producing systems that others depend on, as well as at the end of every schedule.

rust

fn spawn(mut commands: Commands) {
  commands.spawn_empty();
}

Spawning components

rust

commands.spawn(Player).insert(Transform::default());
// or with a tuple bundle
commands.spawn((Player, Transform::from_xyz(1., 1., 1.)));

Required components

rust

#[derive(Component)]
#[require(Transform)]
struct Player;
// now: commands.spawn(Player) auto-adds Transform

A bare #[require(Foo)] uses Foo::default(), so Foo must implement Default. If you provide a constructor instead, Default is not required. Required components are resolved recursively.

Component lifecycle hooks

Components have five life-cycle hooks for side effects that must happen:

#[component(on_add = ...)]
#[component(on_insert = ...)]
#[component(on_discard = ...)]
#[component(on_remove = ...)]
#[component(on_despawn = ...)]

The hook systems take a DeferredWorld and a HookContext:

rust

use bevy::ecs::lifecycle::HookContext;
use bevy::ecs::world::DeferredWorld;

#[derive(Component, Default)]
#[component(on_add = on_ship_added)]
enum Ship {
  Destroyer,
  Frigate,
  #[default]
  Scout,
}

fn on_ship_added(mut world: DeferredWorld, context: HookContext) {
  world
    .commands()
    .entity(context.entity)
    .insert(Position { x: 0, y: 0 });
}

EntityCommands chaining

spawn/spawn_empty return EntityCommands for chaining:

rust

commands
  .spawn(Player)
  .insert(Transform::default())
  .insert(Name::new("Player 1"));

Despawning

rust

for entity in &query {
  commands.entity(entity).despawn();
}

Commands are deferred

Commands don't execute immediately — they're queued until the next sync point, where Bevy runs its ApplyDeferred system.

Custom commands

Implement the Command trait:

rust

struct SpawnPlanet { radius: f32, position: Vec2 }

impl Command for SpawnPlanet {
  fn apply(self, world: &mut World) {
    let mesh = world.resource_scope(|_w, mut meshes: Mut<Assets<Mesh>>| {
      meshes.add(Circle::new(self.radius))
    });
    // ...
    world.spawn((Planet::new(self.radius), Mesh2d(mesh), Transform::from_translation(self.position.extend(0.))));
  }
}
// usage:
commands.queue(SpawnPlanet { radius: 100., position: Vec2::ZERO });

Extending the Commands API

rust

trait MyExt {
  fn do_thing(&mut self);
}
impl<'w, 's> MyExt for Commands<'w, 's> {
  fn do_thing(&mut self) { info!("thing done"); }
}

Testing commands

rust

use bevy::ecs::world::CommandQueue;

let mut world = World::default();
let mut queue = CommandQueue::default();
queue.push(MyCommand);
queue.apply(&mut world);
