- Metamask Official Flaky Test DetectionDetect, prevent, and fix flaky Jest unit tests in MetaMask Mobile before they reach CI. Use this skill when: reviewing a PR diff or changed test files for flakiness risk, fixing an intermittently failing Jest test, reproducing a flaky test locally, or auditing GitHub Actions history to rank historically flaky unit tests by failure rate.Votes: 0GitHub stars: 73
- Metamask Official Gator CliUse when you need to operate the @metamask/gator-cli to initialize profiles, upgrade EOA to EIP-7702, grant, redeem, and revoke ERC-7710 delegations, or inspect balances and delegations.

- Metamask Official Mobile Visual TestingDrives the MetaMask Mobile via the mm CLI for visual testing in IOs simulator or Android emulator. Use when asked to visually verify UI changes, capture screenshots or debug Mobile UI state. Trigger phrases include "verify visually", "take a screenshot", "test the flow", and "check the UI".Votes: 0GitHub stars: 73
- Metamask Official Perf Hooks EffectsExtension UI hooks and effects: when not to use `useEffect`, dependency arrays, why `JSON.stringify` deps are never the fix, cascading effects, `AbortController` cleanup. Use when an effect loops or fires every render, deps are stringified to force equality, or state lands after unmount. Rendering goes to `perf-rendering`.Votes: 0GitHub stars: 73
- Metamask Official Perf React CompilerReact Compiler in the Extension UI: what it optimizes, where it bails out, and when manual memoization is still needed. Use when deciding whether `useMemo`, `useCallback` or `React.memo` are still required, reviewing reflexive memoization, or working out why a component isn't optimized. Dependency arrays go to `perf-hooks-effects`.Votes: 0GitHub stars: 73
- Metamask Official Perf RenderingExtension UI render performance: list keys, virtualization, `React.memo`, code splitting, Web Workers, debouncing. Use when a long list stutters, scrolling feels janky, a component re-renders more than it should, or a route loads slowly. Effects go to `perf-hooks-effects`; selectors to `perf-state-management`.Votes: 0GitHub stars: 73
- Metamask Official Perf State ManagementExtension Redux state and selectors: reducer purity, keeping non-serializable values out of the store, normalization, Immer, batching, identity output selectors. Use when components re-render on unrelated state changes, a selector returns a fresh identity every call, or state is mutated in a reducer. Memoization goes to `perf-rendering`.Votes: 0GitHub stars: 73

- Metamask Official PerformanceUse for any performance question about the MetaMask Mobile React Native app. Trigger when: a screen, list, or interaction feels slow, laggy, or janky (account/network switching, scrolling, typing, FPS drops); planning a feature with real-time/websocket data, frequent updates, or large lists; reviewing or auditing PRs/code for excessive re-renders, broken selector memoization, Context providers, hook deps, or bundle bloat; making the app faster for power users with many accounts/assets; measur...Votes: 0GitHub stars: 73
- Metamask Official Perps Breakdown TicketsInteractively break a perps product requirement into split, dispatch-ready technical tickets across MetaMask Core, its release, Mobile, and Extension. Use when a product manager (or a codebase-aware Claude acting for one) has a perps bug or feature and needs engineering-grade tickets, correctly routed now that @metamask/perps-controller is the Core source of truth. Triages where the change actually lives, emits only the applicable layer tickets with dependency links, and enforces token-effici...Votes: 0GitHub stars: 73
- Metamask Official Perps Review PrExecute the Perps static review checklist when explicitly invoked by name or a selected workflow.Votes: 0GitHub stars: 73
- Metamask Official Perps Validate MultiprojectInteractively validate perps changes across local MetaMask Core, Mobile, and Extension checkouts. Use when a Core @metamask/perps-controller change must be checked in Mobile/Extension, or when a Mobile/Extension perps change needs parity validation in the other client. Defaults to current checkout as owner, yalc for Core package transport, read-only validation targets, and the smallest meaningful proof; asks the user only when required folders or proof level cannot be resolved.Votes: 0GitHub stars: 73
- Metamask Official Perps Write TicketInteractively author one clean, complete perps ticket — bug, EPIC, or initiative — that states intent and expected outcome without implementation. Use when a PM (or a Claude acting for one) has a raw perps observation, feature idea, or strategic goal and wants a single well-formed ticket ready for engineering to break down. This is the first (product) pass; the engineering split + layer routing is a separate pass (perps-breakdown-tickets). Captures what/expected/repro, makes the ticket surfac...Votes: 0GitHub stars: 73

- Metamask Official Swaps Cpu Profile AuditParse an already-recorded Hermes / React Native Release Profiler `.cpuprofile` and audit it for slow frames on the swaps/bridge screen and its modals (quote select, post-trade, batch sell, asset picker). Use when a user hands you a `.cpuprofile` (e.g. `sampling-profiler-trace*.cpuprofile`) and asks to audit, analyze, or explain why the swaps/bridge flow is slow. Offline, file-based analysis — no simulator, device, Metro, or `mm` session required, unlike `swaps-perf-audit` (live render counts ...Votes: 0GitHub stars: 73
