Default output: return only the result, blockers, and required evidence. Omit preambles, process narration, repeated context, confidence scores, and follow-up offers. Use at most five bullets unless a required artifact or schema needs more.

Source-Driven Development

Overview

Verify every framework or library decision against official documentation before implementing. Flag any decision that lacks a source. This skill prevents the agent from relying on outdated patterns, hallucinated APIs, or assumptions about library behavior.

When to Use

• Working with a framework or library you have not used recently
• When API surface area is large or frequently changing
• When the cost of a wrong assumption is high (auth, data, security)
• When documentation lookup tools are available
