What problem does it solve?

This Skill helps systems architects and reviewers determine whether proposed technical plans are actually buildable by identifying architecture conflicts, unacknowledged dependencies, migration risks, and missing implementation details that would block engineering teams.

Core Features & Use Cases

• Existing system alignment: Checks whether the plan acknowledges current code, services, and infrastructure and flags assumptions of greenfield.
• Architecture reality & dependency analysis: Detects stack conflicts, implicit dependencies, and missing integrations.
• Shadow path tracing: Traces happy, nil, empty, and error flows for new data paths and reports unhandled cases.
• Performance, migration, and implementability checks: Provides back-of-envelope performance estimates, evaluates migration and rollback strategies, and assesses whether engineers can start implementing from the plan.
• Use Case: Run against a design RFC or pull request description to produce actionable findings and a confidence level that guide engineers before implementation begins.

Quick Start

Review the attached design document and identify architecture conflicts, missing dependencies, migration risks, and concrete implementability gaps.
