Tracely-ai: Skill for Claude Code

.agents/skills/compose-graphics/SKILL.md

compose-graphics is a skill for Claude Code, Codex from Jwuthri/Tracely-ai. It costs 36 tokens per session (4,472 once invoked), scanned A, original, MIT.

A guide to advanced visual effects in Jetpack Compose, Android's Kotlin interface toolkit. It covers spring motion, shaders, custom drawing, GPU effects, and Material 3 expressive visuals.

In plain words
What is it for?
Use it for shader effects, particle or generative drawing, blur and color effects, expressive motion, and custom graphics in Android interfaces.
Why use it?
It helps select an appropriate Compose technique for effects that go beyond ordinary interface animation, including effects with Android-version requirements.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Jwuthri/Tracely-ai's own configuration. It tells Claude Code and Codex how to work on Tracely-ai itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Tracely-ai configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Foundation: `../compose-motion/SKILL.md` covers basics. Concise rules here. Deep-dive in `references/`..

About the project

Tracely is a CI/CD system for AI agents that turns failed production traces into replayable regression tests. Development teams use it to detect and group agent failures, run the resulting cases on pull requests, and block changes that reproduce those failures. The catalogue entries provide skills for operating this trace-based testing and observability workflow.

Token cost

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.

Fable 5.1 $0.00036 $0.04472
Opus 5 $0.00018 $0.02236
Sonnet 5 $0.00007 $0.00894

Security

Grade A, and why

compose-graphics 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 7d 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 — 504 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Compose Graphics

Advanced Compose visuals: M3 Expressive motion physics, AGSL shaders (Android 13+), Canvas / DrawScope, graphicsLayer effects. Loaded for advanced thesis (shader, expressive, M3 Expressive, AGSL, Canvas, holographic). Foundation: ../compose-motion/SKILL.md covers basics. Concise rules here. Deep-dive in references/.


Decision Tree: Which API for Which Need

Need API
Spring physics with bounce / overshoot MotionScheme.expressive() (M3 Expressive)
Pixel-level shader RuntimeShader + Modifier.graphicsLayer { renderEffect = ... } (Android 13+)
Generative drawing (paths, particles, fractals) Canvas { drawScope -> ... }
GPU effects (blur, shadows, color filters) Modifier.graphicsLayer { renderEffect = ... } or Modifier.blur(...)
Adaptive system materials (Material You glassmorphism) Modifier.background(MaterialTheme.colorScheme.surfaceContainerHighest)
Liquid glass on Android AGSL shader recipe (no native API like iOS yet)

Domain 1: Material 3 Expressive

What It Is

The 2025 Material 3 evolution introduces spring-based motion physics replacing fixed-duration tweens. New shape morphing API via androidx.graphics.shapes. New MotionScheme selectable on the theme. Aimed at hero moments, key interactions, brand-defining UI.

MotionScheme

Scheme Personality Use For
MotionScheme.standard() Calmer, less overshoot Default for chrome, lists, navigation
MotionScheme.expressive() More overshoot, longer settle Hero reveals, FABs, primary CTAs

Apply on the theme:

MaterialTheme(motionScheme = MotionScheme.expressive()) {
    // children read tokens via MaterialTheme.motionScheme.*
}

Tokens exposed:

Token Domain Speed
fastSpatialSpec() Position / size < 200ms
defaultSpatialSpec() Position / size ~ 350ms
slowSpatialSpec() Position / size ~ 600ms
fastEffectsSpec() Opacity / color < 150ms
defaultEffectsSpec() Opacity / color ~ 250ms
slowEffectsSpec() Opacity / color ~ 400ms

Changes

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.
