PR Readiness Check

Scan the current branch diff for common issues that could be flagged during PR review. This is a non-blocking check — always report findings as warnings and let the user decide what to act on.

Steps

1. Collect the diff

   git diff main...HEAD --name-only
   git diff main...HEAD

2. Check for missing tests

   For each new or modified source file with non-trivial logic changes (not just config, docs, or styles), check whether a corresponding test file was added or updated.

   Heuristic: a source file Foo.ts(x) should have a matching Foo.test.ts(x) (or Foo.view.test.tsx for components). Warn if:

   • New exported functions/components have no corresponding test file changes
   • Existing test files were not updated despite significant logic changes in the source

3. Check for missing JSDoc

   Scan new exported functions, types, and components in the diff. Warn if any lack JSDoc comments.

4. Check for guideline violations

   Look for obvious violations of .github/guidelines/CODING_GUIDELINES.md and .cursor/rules/ patterns in the changed lines:

   • any type usage in TypeScript
   • StyleSheet.create() in new code
   • Raw View or Text imports from react-native instead of design system Box/Text
   • import tw from 'twrnc' instead of useTailwind() hook
   • npx usage in scripts

Output

Print each finding as a warning line:

⚠ No tests detected for new logic in `app/core/Foo.ts`
⚠ Missing JSDoc on exported function `calculateFee` in `app/util/fees.ts`
⚠ `any` type used in `app/components/Bar.tsx:42`
⚠ `StyleSheet.create()` found in new file `app/components/Baz/Baz.tsx`

If no issues found, confirm:

✅ No readiness issues detected
