hk-mock-first

hk-mock-first is a Test-driven development skill for AI agents, published by deepklarity in the harness-kit repository on GitHub. Skillspace rates hk-mock-first C (73/100) and it passed the safety scan; the rating is based on static analysis only.

Mock-first, layer-by-layer feature development. Instead of building a feature end-to-end and hoping the interface works, start by mocking at the user-facing surface with realistic data, get user acceptance on the experience, then deepen one complexity layer at a time with TDD. Everything is anchored on disk so work survives across sessions. Use whenever building a new feature, adding significant UI, planning a multi-layer change, or when the user mentions 'mock first', 'let me see it first', 'prototype this', 'simulate this feature', 'build this layer by layer', or /hk-mock-first.
