nexus-phase-preflight

What problem does it solve?

This Skill provides a pre-implementation factual evolution check for SBFB phases, ensuring that the design aligns with historical decisions, threat models, and wire format invariants before coding begins.

Core Features & Use Cases

• Factual Evolution Check: Runs four scans (S1 SOTA delta, S2 historical decisions, S3 threat model coverage, S4 wire format invariants) to emit a verdict.
• Documentation Generation: Outputs a sprint-specific preflight document or pivot proposal based on the verdict.
• Use Case: Before writing the first code line of a SBFB phase, run the nexus-phase-preflight skill to validate the design and avoid potential conflicts.

Quick Start

Run the 'preflight phase X' command to initiate the preflight check for phase X.
