Use this skill whenever Naveen is starting a new coding project, script, or automation. Triggers when Naveen types /harness-first, says "start a new project", "scaffold this", "set up the structure", or begins any build where code will be written across multiple sessions. This skill prevents the class of problems where builds lack a testing structure, making it impossible to verify that individual components work before wiring them together. Always apply at the start of Phase 4 (Implement) in the /build skill. Harness-first is how Naveen's code stays reliable across multi-session builds.
