Wallets by @metamask v1.0.0 C PASS 6 flags

Use for any performance question about the MetaMask Mobile React Native app, at any stage. 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 and wanting to avoid perf pitfalls before building; 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; measuring time-to-interactive, render counts, or FPS and surfacing them in Sentry; analyzing a captured `.cpuprofile` / React Native Release Profiler trace (e.g. a `sampling-profiler-trace*.cpuprofile`) to find why a flow is slow; or adding render-regression tests so CI catches slowdowns. Covers re-renders, reselect memoization, FlashList, Reanimated, TTI, bundle size, trace() instrumentation, and Release Profiler CPU-profile analysis. Not for correctness bugs, styling/spacing, Solidity gas, or the browser extension.

Capabilities below are detected automatically by an open-source scanner that reads the skill's text and scripts (see how this is computed). Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

6 Red flags things this skill can do that affect your security or funds

⚠
Requires private key you must hand over a private key, mnemonic, or wallet config
⚠
Uses remote install script setup pipes a remote shell script (curl | sh class)
⚠
Mutable remote runtime runs remote code that can change behavior without a local diff
⚠
Can install code installs software at setup time (npx, pip, brew, etc.)
⚠
Can execute shell runs arbitrary shell commands on your machine
⚠
Can spawn sub-agents delegates to other skills or sub-agents

4 Cleared by scanner we scanned the skill's text & scripts and found no evidence of these

✓
Can move funds this skill can sign and send transactions on your behalf
✓
Requires hosted operator depends on a third-party hosted service to function
✓
Can browse the web fetches arbitrary URLs at runtime
✓
Can write files writes to your local filesystem

1 Not measured yet scanner couldn't make a confident call — treat as a possible red flag

Auto-invocable may be invoked by the agent without your explicit prompt

Ingredients (services this skill talks to)

We did not find any well-known hosted services in this skill's text or scripts. This does NOT mean the skill is local-only — it might use services we don't yet recognize, or talk to them through code paths our scanner can't reach. A complete dependency list (every package, library, and binary, with integrity hashes) is on the roadmap; today we only show recognized hosts.

Audits

No one has audited this skill yet. That is different from “audited and clean” — it just means no professional reviewer (a security firm, the CryptoSkill team, or a verified independent researcher) has signed off on it. There are no audit reports to read. How reviewer levels work →
