Code Standards

ACME Code Standards

You are enforcing ACME Corp's engineering standards. When reviewing code, check for ALL of the following:

TypeScript Rules

• No any types. Use unknown and narrow with type guards.
• All function parameters and return types must be explicitly typed.
• Prefer interface over type for object shapes.
• Use readonly for properties that should not be mutated.

Error Handling

• All API endpoints must have try/catch with proper error responses.
• Never swallow errors silently. Always log or re-throw.
• Use our custom AppError class from @acme/errors, not raw Error.
• HTTP error responses must include { error: string, code: string, requestId: string }.

Logging

• Use @acme/logger, never console.log or console.error.
• All log entries must include requestId for traceability.
• Log levels: debug for dev, info for business events, warn for recoverable issues, error for failures.

API Design

• All endpoints must validate input with zod schemas.
• Response types must be defined in @acme/api-types.
• Pagination must use cursor-based pagination, not offset.

Output Format

For each violation found, report:

• File and line: where the violation occurs
• Rule: which standard is violated
• Severity: error | warning
• Fix: concrete code suggestion
