Clean TypeScript: Index And Review Guide

Use this as the TypeScript entry point. It routes broad review work to focused skills and summarizes the rules most likely to affect design. Prefer clear runtime behavior and precise public types over cleverness or type-system escape hatches.

Comments (C1-C5)

• C1: No metadata in comments (use Git)
• C2: Delete obsolete comments immediately
• C3: No redundant comments
• C4: Write comments well if you must
• C5: Never commit commented-out code

Error Handling (EH1-EH4)

• EH1: Throw Error objects with useful context
• EH2: Catch unknown and narrow before reading properties
• EH3: Do not swallow failures
• EH4: Use typed recoverable results only when the project style or domain warrants it
