What
New skill agents-architect shipped (v1.2.1, 1830 lines, priority 95, 28 sections + 2 references files). SOLE authority for AJ’s AI-agent fleet on the locked Temporal-substrate + LangGraph/Mastra-runtime stack with mandatory AgentRunner portability + sandbox layer for untrusted execution. Auto-loads on 29 agent-related triggers. Owns: lifecycle, RACI, banned patterns, design pattern catalog, Search Attribute schema, Temporal recipes (Worker Versioning, Patching, Signals, Schedules, Continue-as-New, retry policies, Heartbeats), Mission Control wiring (Grafana + PromQL recording rules + Slack alerts), 12 operational runbooks (RB-1 through RB-12), cost methodology, sandbox invocation, HITL bridge, DR + upgrade procedures, dependency map, MCP tool surface (agent-fleet-mcp 9th Permanent MCP candidate). 12-month reassessment gate locked at 2027-05-10.
Why
Routing decisions for any agent-fleet work must now defer to agents-architect. architecture-orchestrator and delivery-orchestrator should compose at boundaries (design + deploy) but agents-architect dominates for agent work itself. Two-layer Temporal+LangGraph decision is locked — no re-litigation until 12-mo gate.
Action Required
Update routing knowledge to defer to agents-architect on any agent-related task. Compose at design/deploy boundaries. Do NOT initiate agent-orchestrator comparison work — locked decision.
