Source-Driven Development

Never rely on training data for API usage. Read the actual source of truth.

Workflow

1. Identify Dependencies

• Read package.json (or equivalent manifest) for exact versions
• Note the exact version of each library involved in the task

2. Fetch Official Docs

For each dependency involved:

1. Find the correct docs URL for that specific version (not "latest")
2. Fetch the relevant API page using WebFetch
3. Extract: function signatures, required params, return types, breaking changes
