What problem does it solve?
Comprehensive pre-build and active-build harness that captures every concern Winston/Novendor developers worry about when implementing features, fixing bugs, or extending the platform. Produces a concern-aware build plan AND stays active as a guardrail harness during implementation. Use this skill before starting ANY non-trivial Winston work — feature builds, bug fixes, new surfaces, schema changes, prompt edits, write-tool additions, dashboard work, credit decisioning changes, PDS phases, or performance optimization. Also use when someone says "build this", "implement this", "add this feature", "fix this", or any task that touches multiple surfaces. If you're about to start writing code in the Winston repo and haven't loaded this skill, stop and load it first. This is the "did I think of everything?" checklist that prevents the regressions we've actually had.
Core Features & Use Cases
The skill operates in two phases: Plan (before you write code) and Harness (while you write code). It generates a concern-aware build plan and remains active as a guardrail during implementation to catch regressions across surfaces.
Quick Start
Load this skill before starting Winston work to ensure all concerns are captured and guardrails stay active during implementation.
