Agent Communication Protocol — fan-out dispatch reference for Claude plugin orchestration
Disciplined 6-phase bug diagnosis loop. Build feedback loop, reproduce, hypothesise, instrument, fix with regression test, cleanup with post-mortem. Use for all bugs — bypasses PRD entirely. Ends with advisor-gate completion gate.
Interview-based planning skill. Ask one question at a time with recommended answers, cross-reference codebase, detect and defer to project-level planning conventions, and synthesize a concise plan that feeds vertical-slice. Use for features, small changes, and bug scoping.
Run the groundwork acceptance test harness. Documents how to test the plugin locally.
MANDATORY user acceptance testing before advisor-gate. Enforces real end-user testing — TUI via tmux/expect, API via real HTTP calls in docker-compose, web apps via Playwright browser. Unit/integration tests are INSUFFICIENT unless they exercise the system exactly as end-users experience it. No exceptions.
Engage maximum parallel fan-out mode. Use when you want to work 10x faster by dispatching all independent work simultaneously to specialist agents. Triggers on "ultrawork", "ulw", "fan out hard", "go parallel".
Bootstrap skill for the groundwork workflow suite. Loaded at every conversation start. Establishes core rules, skill triggers, and the 1% escalation heuristic. ALWAYS load this first.
Mid-session codebase architecture review. All exploration runs in isolated subagents so findings never pollute main context. Surfaces shallow modules, coupling smells, and testability gaps as an HTML report. Use between tasks to retrospect on architecture without bloating the session context window.
