Agent skills from experts worth learning from.

The clearest reason to install Matt’s collection. Grill Me turns vague intent into a visible decision tree and refuses to let the agent silently fill gaps, which directly addresses the most expensive failure in agentic coding: building the wrong thing quickly.

Grill With Docs improves on a normal requirements interview by turning resolved language and architectural choices into durable project context. That makes later sessions shorter and reduces inconsistent naming across both code and agent explanations.

A pragmatic, seam-oriented TDD guide that insists on observing the failure before implementation and favors tests through public behavior. It is especially useful when coding agents otherwise add tests after the fact to bless what they already wrote.

This skill makes debugging a sequence of evidence-producing gates: reproduce, minimize, hypothesize, instrument, fix, and regression-test. It is a strong antidote to agents editing the first suspicious line and declaring victory.

Codebase Design gives agents a compact architectural vocabulary centered on deep modules, narrow interfaces, locality, and testable seams. It improves design conversations without pretending that a generic architecture pattern fits every repository.

Interview Me is Addy’s strongest entry point for vague work. It asks one question at a time until underlying intent is clear, creating a measured human checkpoint before the broader lifecycle begins.
