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.

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 | $0.00029 | $0.03273 |
| Opus 5 | $0.00015 | $0.01636 |
| Sonnet 5 | $0.00006 | $0.00655 |
| Haiku 4.5 | $0.00003 | $0.00327 |
Grade A, and why
compose-motion 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.

Compose Motion - Sub-skill
Jetpack Compose animation core. Loaded for Android Compose and Compose Multiplatform projects. Concise rules here. Deep-dive in
references/. Baseline: Compose 1.7+ (April 2026 stable). Modern stable APIs only - noswipeable, noanimateContentSizehacks whereAnimatedContentis correct.
API Decision Tree
| Need | API |
|---|---|
| Single value over time | animateFloatAsState, animateDpAsState, animateColorAsState, etc. |
| Visibility / mount-unmount | AnimatedVisibility(visible) { ... } |
| Crossfade between states | Crossfade(target) { state -> ... } |
| Multi-state coordinated | updateTransition(target).animateFloat { ... } |
| Manual control / interruption | Animatable(initialValue) + animateTo(...) |
| Looping / infinite | rememberInfiniteTransition().animateFloat(...) |
| Shared elements | SharedTransitionLayout + Modifier.sharedElement(...) (Compose 1.7+) |
| Layout swap with anim | AnimatedContent(target) { ... } |
| Drag / swipe | Modifier.draggable + Animatable.snapTo/animateTo, or Modifier.anchoredDraggable for snap-points |
Rule: climb the ladder only when needed. animate*AsState covers 70% of cases. Reach for Animatable only when you need to interrupt, chain, or read velocity.
Spring API (opinionated defaults)
| Use | Spec |
|---|---|
| UI snap (modal, drawer, tab) | spring(stiffness = Spring.StiffnessMediumLow, dampingRatio = Spring.DampingRatioNoBouncy) |
| Tactile (button press release, toggle) | spring(stiffness = Spring.StiffnessMedium, dampingRatio = 0.85f) |
| Bouncy reveal (toast, FAB, success) | spring(stiffness = Spring.StiffnessLow, dampingRatio = Spring.DampingRatioMediumBouncy) |
| Drag follow (1:1 finger tracking) | spring(stiffness = Spring.StiffnessHigh, dampingRatio = 1f) |
Stiffness constants: VeryLow 200, Low 400, MediumLow 700, Medium 1500, High 10000. Higher = faster settle. Damping constants: HighBouncy 0.2, MediumBouncy 0.5, LowBouncy 0.75, NoBouncy 1.0. Below 1.0 overshoots. Springs ignore durationMillis; if you need a deterministic duration, use tween(...) instead.
What ships with it
3 files 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.
- 7d ago First seen · 360 lines · 29 tokens per session scan A f1673ec03144
compose-motion is a skill published in the GitHub repository Jwuthri/Tracely-ai (1,193 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 3,273 once invoked, about $0.0001 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 2026-08-30.
