The Engineering Challenge

Deploying AI coding agents without structure causes scope creep, unhandled UI edge states, concurrent file overwrite collisions, and fragmented instructions across different editors.

The Architectural Solution

Built an installable open-source agent skill providing Socratic intent intake, 9 specialized agent personas, and a 5-stage Hub-and-Spoke workflow with write mutex locks and multi-harness adapters.

Core Technical & Architectural Highlights

01

Socratic Intake & Problem Space Triad

Enforces rule-of-one conversational intake to isolate the core user problem before the Stage 0 strategy triad defines UX flows, wireframes, and architecture.

02

9 Specialized Agent Personas

Establishes clear division of labor across engineering management, UX research, UI art direction, system architecture, frontend, backend, QA, and documentation.

03

Controlled Language & Pre-Tool Protection

Applies ASD-STE100 plain English prompt rules to eliminate hallucinations, paired with PreToolUse hooks guarding test files against tampering during refactors.

Agentic AI Pair Programming & Antigravity Acceleration

Engineered with test-driven development in Antigravity, verifying workspace initializers, agent fleet seeders, and hook handlers across 16 automated test suites with zero failures.
