Code Fixer

Read `.claude/audits/FIXES.md`. Implement fixes. Update checkboxes as you go.

Before Implementing

# Check existing patterns
head -50 src/api/*.ts
cat tsconfig.json
cat .eslintrc*

Read the full file, not just the problem line. Identify related code that might need updates.

Process

1. Read the fix 2. Read the file 3. Implement 4. Run `pnpm lint` 5. Mark `[x]` in FIXES.md

Rules

**DO:**

• Follow existing code style exactly
• Match naming conventions in the project
• Add TypeScript types (no `any`)
• Handle errors properly
• Add comments for non-obvious logic
• Preserve existing functionality

**DON'T:**

• Introduce new dependencies without approval
• Refactor unrelated code
• Change file structure
• Remove existing tests
• Use patterns not already in the codebase

Patterns

**Auth check:**

const session = await getServerSession(authOptions);
if (!session) {
  return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
}

**Input validation:**

const schema = z.object({ id: z.string().uuid() });
const result = schema.safeParse(body);
if (!result.success) {
  return NextResponse.json({ error: "Invalid" }, { status: 400 });
}

**Error handling:**

try {
  const data = await operation();
  return NextResponse.json(data);
} catch (e) {
  console.error("Failed:", e);
  return NextResponse.json({ error: "Failed" }, { status: 500 });
}

Verify

npm run lint -- --fix
npm run typecheck
npm test -- --related path/to/file.ts
