Validation prompt
Confirm the detector match and collect the required evidence before deciding whether an edit is warranted.
Fires on a literal ObjectExpression, ArrayExpression, ArrowFunctionExpression, or FunctionExpression sitting directly inside a useEffect, useLayoutEffect, useMemo, or useCallback deps array. Each creates a fresh reference every render, so Object.is comparison always fails and the hook re-runs every render. Identifier deps that happen to resolve to literals defined elsewhere 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.
For object or array literals, lift to module scope or wrap with useMemo so the reference is stable. For inline functions, hoist outside the component when they capture no reactive values, or wrap with useCallback otherwise. A useRef works when you don't actually need re-runs on change.

Repository-wide copy prompt
Use this repository-wide prompt only after validating each occurrence. For one occurrence, use the guidance above.
Show repository-wide prompt
Fix every confirmed react-doctor/rerender-dependencies diagnostic in the current repository.
Required change:
- For object or array literals, lift to module scope or wrap with useMemo so the reference is stable. For inline functions, hoist outside the component when they capture no reactive values, or wrap with useCallback otherwise. A useRef works when you don't actually need re-runs on change. See https://react.dev/learn/removing-effect-dependencies#does-some-reactive-value-change-unintentionally.
Validation before editing:
Fires on a literal ObjectExpression, ArrayExpression, ArrowFunctionExpression, or FunctionExpression sitting directly inside a useEffect, useLayoutEffect, useMemo, or useCallback deps array. Each creates a fresh reference every render, so Object.is comparison always fails and the hook re-runs every render. Identifier deps that happen to resolve to literals defined elsewhere are not flagged.
Constraints:
- Make the smallest change that fixes the root cause.
- Preserve behavior and interfaces unrelated to this diagnostic.
- Reuse existing project components, utilities, and conventions.
- Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations.
- Adapt identifiers and framework details instead of copying blindly.
- Do not disable the rule or suppress matching code.
- Do not edit code when this condition applies: react-compiler.
Assessment:
- Record detector evidence, applicability facts, assumptions, missing evidence, and the rule class for this occurrence.
- Return one outcome: Confirmed failure, Rejected, Needs evidence, Unavailable, Waived with evidence, or Observation.
- A waiver records the established failure, scope, authority, evidence, and review or expiry condition. It is not a pass or false positive.
Verification:
- Run focused tests for the changed behavior.
- Run React Doctor and confirm this diagnostic no longer appears from changed code.
- Run an unfiltered scan of the affected scope before claiming no cross-category regression.
- Report the files changed and any checks you could not run.
