What it does

Bevy Gizmos is an agent skill from nolantait/bevy-starter. Reference for Bevy gizmos — immediate-mode visual debugging, GizmoPlugin, Gizmos system param, retained GizmoAsset, config groups, and line styles.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

When your agent uses it

Development work in your project

Example prompts

“/bevy-gizmos”

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 Gizmos loads about 1.5k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 275 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~40
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

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.

Setup

Gizmos are enabled via GizmoPlugin, which is included in DefaultPlugins:

rust

App::new()
    .add_plugins(DefaultPlugins)  // includes GizmoPlugin
    .run();

Or add it manually: .add_plugins(GizmoPlugin).

Immediate mode — `Gizmos` system param

Gizmos are drawn per-frame and cleared automatically after rendering.

rust

fn draw_gizmos(mut gizmos: Gizmos) {
    gizmos.line(Vec3::ZERO, Vec3::X, GREEN);
}

Use in Update (per-frame) or FixedMain (per-tick).

Drawing primitives

Shape	3D	2D
Line	`gizmos.line(start, end, color)`	`gizmos.line_2d(start, end, color)`
Ray	`gizmos.ray(origin, direction, color)`	`gizmos.ray_2d(origin, direction, color)`
Linestrip	`gizmos.linestrip(positions, color)`	`gizmos.linestrip_2d(positions, color)`
Lineloop	`gizmos.lineloop(positions, color)`	—
Rect	`gizmos.rect(isometry, size, color)`	`gizmos.rect_2d(isometry, size, color)`
Circle	`gizmos.circle(isometry, radius, color)`	`gizmos.circle_2d(isometry, radius, color)`
Sphere	`gizmos.sphere(isometry, radius, color)`	—
Ellipse	`gizmos.ellipse(isometry, half_size, color)`	`gizmos.ellipse_2d(isometry, half_size, color)`
Cube	`gizmos.cube(transform, color)`	—
Arrow	`gizmos.arrow(start, end, color)`	`gizmos.arrow_2d(start, end, color)`
Cross	`gizmos.cross(isometry, half_size, color)`	`gizmos.cross_2d(isometry, half_size, color)`
Grid	`gizmos.grid(rotation, cells, spacing, color)`	`gizmos.grid_2d(...)`
AABB	`gizmos.aabb_3d(aabb, transform, color)`	—

Lines with color gradients

rust

gizmos.line_gradient(Vec3::ZERO, Vec3::X, GREEN, RED);
gizmos.ray_gradient(Vec3::Y, Vec3::X, CYAN, MAGENTA);
gizmos.linestrip_gradient([(Vec3::ZERO, GREEN), (Vec3::X, RED)]);

Curves

Requires bevy_math::curve::Curve trait:

rust

let domain = Interval::UNIT;
let curve = FunctionCurve::new(domain, |t| Vec2::from(t.sin_cos()));
gizmos.curve_2d(curve, (0..=100).map(|n| n as f32 / 100.0), RED);
gizmos.curve_3d(curve_3d, times, BLUE);

// With gradient:
gizmos.curve_gradient_2d(curve, (0..=100).map(|n| n as f32 / 100.0).map(|t| (t, GREEN.mix(&RED, t))));

Arcs & ellispes

Arc builder methods return a builder with .resolution(n):

rust

gizmos.arc_3d(angle_rad, radius, isometry, color).resolution(64);
gizmos.short_arc_3d_between(center, from, to, color);
gizmos.long_arc_3d_between(center, from, to, color);

Arrow builder

rust

gizmos.arrow(start, end, ORANGE_RED)
    .with_double_end()
    .with_tip_length(0.5);

Axes

Draw XYZ axes from a transform:

rust

gizmos.axes(transform, base_length);
gizmos.axes_2d(transform, base_length);

Rounded cuboids / rectangles

rust

gizmos.rounded_cuboid(center, size, TURQUOISE)
    .edge_radius(0.1)
    .arc_resolution(4);
gizmos.rounded_rect(isometry, size, color);
gizmos.rounded_rect_2d(isometry, size, color);

Primitives

All bevy_math primitives renderable:

rust

gizmos.primitive_3d(
    &Plane3d { normal: Dir3::Y, half_size: Vec2::splat(1.0) },
    isometry,
    GREEN,
).cell_count(UVec2::new(5, 10))
 .spacing(Vec2::new(0.2, 0.1));

Config groups

Create custom config groups to independently toggle/style sets of gizmos:

rust

#[derive(Default, Reflect, GizmoConfigGroup)]
struct MyRoundGizmos;

app.init_gizmo_group::<MyRoundGizmos>();

fn system(mut my_gizmos: Gizmos<MyRoundGizmos>) {
    my_gizmos.sphere(Isometry3d::IDENTITY, 1.0, RED);
}

Use AppGizmoBuilder::insert_gizmo_config for custom initial config.

Config store (`GizmoConfigStore`)

Access and modify gizmo configuration at runtime:

rust

fn update_config(mut config_store: ResMut<GizmoConfigStore>) {
    let (config, _) = config_store.config_mut::<DefaultGizmoConfigGroup>();
    config.enabled ^= true;  // toggle visibility
    config.depth_bias = -1.0;  // always in front
    config.line.width = 5.0;
    config.line.perspective ^= true;

    // Custom config group
    let (my_config, _) = config_store.config_mut::<MyRoundGizmos>();
    my_config.line.width += 1.0;
}

Config fields

Field	Type	Description
`enabled`	`bool`	Toggle all gizmos for this group
`depth_bias`	`f32`	-1 (in front) to 1 (behind); 0 = normal
`line.width`	`f32`	Line width in pixels
`line.perspective`	`bool`	Perspective-correct line width
`line.style`	`GizmoLineStyle`	`Solid`, `Dotted`, `Dashed { gap_scale, line_scale }`
`line.joints`	`GizmoLineJoint`	`Bevel`, `Miter`, `Round(n)`, `None`
`mesh`	`MeshConfig`	Mesh gizmo config

AABB gizmos

rust

// Enable on specific entities by adding ShowAabbGizmo component
// Or draw all with:
config_store.config_mut::<AabbGizmoConfigGroup>().1.draw_all = true;

Retained mode (`GizmoAsset` + `Gizmo` component)

For many static lines, use retained gizmos for better performance:

rust

fn spawn_retained(mut commands: Commands, mut gizmo_assets: ResMut<Assets<GizmoAsset>>) {
    let mut gizmo = GizmoAsset::new();
    gizmo.sphere(Isometry3d::IDENTITY, 0.5, CRIMSON)
        .resolution(30_000 / 3);

    commands.spawn(Gizmo {
        handle: gizmo_assets.add(gizmo),
        line_config: GizmoLineConfig { width: 5.0, ..default() },
        ..default()
    });
}

Gizmo component fields: handle (Handle<GizmoAsset>), line_config, depth_bias.

GizmoAsset supports the same drawing API as Gizmos (line, circle, sphere, etc.).

Light gizmos

Feature: bevy_light. Debug visualization of lights:

rust

// Requires bevy_light feature
// Automatically drawn for PointLight, SpotLight, DirectionalLight
