Motion Performance QA Skill for Codex
Run motion performance QA for websites and apps. Use after adding Motion, GSAP, Lenis, scroll scenes, page transitions, hover states, carousels, WebGL sync, observers, timers, RAF loops, or any animation-heavy UI to catch jank, layout shift, leaks, cleanup bugs, reduced-motion gaps, and mobile issues.

Use This Skill
Use this skill for audit animation performance, cleanup, accessibility, and jank.
Operating Contract
- Inspect the existing project before changing code.
- Identify the motion stack, scroll behavior, component lifecycle, reduced-motion handling, and available verification commands.
- Keep motion purposeful: clarify sequence, focus, depth, tactility, or product understanding.
- Follow existing project conventions unless a change clearly improves the result.
- Run available checks and visually inspect responsive/reduced-motion output when the change affects UI.
Required Reference
Read references/motion-performance-qa-guide.md before making architectural or visible UI changes with this skill.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
Use when implementing any feature or bugfix, before writing implementation code
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
Expert guidance for systematic backtesting of trading strategies. Use when developing, testing, stress-testing, or validating quantitative trading strategies. Covers "beating ideas to death" methodology, parameter robustness testing, slippage modeling, bias prevention, and interpreting backtest results. Applicable when user asks about backtesting, strategy validation, robustness testing, avoiding overfitting, or systematic trading development.
Cloud laboratory platform for automated protein testing and validation. Use when designing proteins and needing experimental validation including binding assays, expression testing, thermostability measurements, enzyme activity assays, or protein sequence optimization. Also use for submitting experiments via API, tracking experiment status, downloading results, optimizing protein sequences for better expression using computational tools (NetSolP, SoluProt, SolubleMPNN, ESM), or managing protein design workflows with wet-lab validation.
This skill should be used for time series machine learning tasks including classification, regression, clustering, forecasting, anomaly detection, segmentation, and similarity search. Use when working with temporal data, sequential patterns, or time-indexed observations requiring specialized algorithms beyond standard ML approaches. Particularly suited for univariate and multivariate time series analysis with scikit-learn compatible APIs.
