react-hooks-js/static-components

Validates that components are static, not recreated every render. Components that are recreated dynamically can reset state and trigger excessive re-rendering

Validation prompt

Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.

Fires when a function whose name starts with an uppercase letter (so the compiler treats it as a component) is declared inside another component or hook body: most commonly const ChildComponent = () => ... inside a parent function, or a conditional component reference like type === 'a' ? () => <A /> : () => <B />. Local lowercase helpers are not flagged.

Evidence boundary

The diagnostic proves only that the detector’s modeled source pattern matched. It does not prove runtime impact, product intent, rendered failure, or that one remediation is correct.

Establish the environment, repository policy, exceptions, and required rendered or runtime evidence before deciding the occurrence.

Record one outcome:

• Confirmed failure: The required evidence establishes the violation.
• Rejected: A documented exception or false-positive predicate applies.
• Needs evidence: Named evidence can still be collected.
• Unavailable: Required evidence cannot be collected in this run.
• Waived with evidence: An authorized, scoped exception applies to an established failure.
• Observation: The review records an optional tradeoff without claiming a defect.

A waiver records its scope, authority, evidence, and review condition. It is not a pass or false positive.

Default severity is registry metadata. Use the occurrence’s JSON severity after repository configuration when ordering real findings.

Fix prompt

Apply this candidate correction only after the required evidence confirms the risk.

Hoist the inner component to module scope. If it needs values from the parent, accept them as props (function ThemedButton({ theme }) instead of capturing theme from closure). Recreating the function every render gives it a new identity, so React unmounts and remounts the entire subtree on each parent render, destroying all child state and DOM.

Repository-wide copy prompt

Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.
