Agent Skills: code-first

Autonomous async Execution. The Architect hands off and walks away; the Agent drives the Task to done — makes every Architectural call via /trace + /pcc + ranking, executes through /subagents, verifies from each implementing Subagent's Evidence (they exercise their own flows, real browser for UI), and returns finished code plus the recorded Decisions for review. TRIGGER when the Architect says "code-first", "/code-first", "execute with /subagents", "execute directly & autonomously", "drive it and report back", "iterate until done", "I'm going to bed", "off to bed", or signals an AFK / overnight handoff. DO NOT TRIGGER when the Architect wants options before action — that is the default mode (propose via /pcc and wait).
