Validation prompt

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

The detector reports non-whitespace JSX text, numeric/string literals, or template literals directly under a known React Native non-text host, a locally proven non-text wrapper, or an imported wrapper resolved as forwarding children to a non-text host. It skips files with a 'use dom' directive, intrinsic HTML/SVG elements, detected text wrappers, supported Expo UI ListItem usage, and subtrees inside a Platform.OS === 'web' branch; it does not skip a file merely because its name ends in .web.tsx. For a custom Button, Chip, Link, or similarly named component, inspect its import or implementation: suppress only when the value is proven to reach Text or the DOM, and confirm when children can reach a native View-like host.

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.

Principle: the value must reach a <Text> before it hits a React Native host primitive: wrap it, don't just relabel the parent. (A) Direct fix on an RN primitive: 'return <View>{count} items</View>' becomes 'return <View><Text>{count} items</Text></View>'; coalesce sibling raw nodes into ONE Text with a template literal: '<Text>{${selectedPage} of ${pageCount} pages}</Text>': not several adjacent <Text> nodes. (B) Single chars, numbers, and ternaries that resolve to a string still need a Text: '<View><Text>{isFocused ? "" : "Click to enable"}</Text></View>'. (C) If the parent is a custom component you own (e.g. a button) make IT render its children in <Text> internally, then '<MyButton>Save</MyButton>' is correct everywhere and the rule stops flagging callers. ANTI-PATTERNS: do NOT 'fix' by renaming the parent to sneak in an allowlist keyword (e.g. wrapping in a no-op <Label>) just to silence the linter: that suppresses without rendering text safely; and do NOT add <Text> around content already inside a DOM/web element ('div','span','a', styled.div): on web that is valid HTML and a stray <Text> is wrong, so suppress instead. See https://reactnative.dev/docs/text

Validation before editing:

The detector reports non-whitespace JSX text, numeric/string literals, or template literals directly under a known React Native non-text host, a locally proven non-text wrapper, or an imported wrapper resolved as forwarding children to a non-text host. It skips files with a 'use dom' directive, intrinsic HTML/SVG elements, detected text wrappers, supported Expo UI ListItem usage, and subtrees inside a Platform.OS === 'web' branch; it does not skip a file merely because its name ends in .web.tsx. For a custom Button, Chip, Link, or similarly named component, inspect its import or implementation: suppress only when the value is proven to reach Text or the DOM, and confirm when children can reach a native View-like host.

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.
  • Before editing, inspect the manifest, lockfile, native app configuration, React Native and Expo versions, and New Architecture status.
  • Also inspect the Reanimated major, installed list-library majors, and every affected platform-specific file.
  • Do not add or upgrade a native dependency, change linking, or alter Pods/Gradle setup unless explicitly authorized.
  • Do not enable the New Architecture or change Expo/native configuration unless explicitly authorized.
  • Preserve navigation, gesture, keyboard, safe-area, accessibility, lifecycle, and platform semantics; do not treat them as file-local import substitutions.
  • Verify behavior in a release build on each affected device platform in scope. Name any unavailable platform instead of claiming it passed.
  • Adapt identifiers and framework details instead of copying blindly.
  • Do not disable the rule or suppress matching code.
  • Confirm this rule is enabled for the project: framework=react-native and capabilities=react-native.

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.
