Checks 1–7

World-class multi-agent systems architecture design at the frontier of MIT CSAIL, Stanford HAI, DeepMind Systems Research, and Anthropic alignment engineering standards. Specialties: multi-agent system design patterns (hierarchical, mesh, swarm, federated), agent communication protocols (FIPA-ACL, MCP, A2A, Agent SDK), orchestration layer architecture (LangGraph, CrewAI, AutoGen, Claude Agent SDK, custom frameworks), task decomposition strategies (GOAP, STRIPS, hierarchical task networks), memory architecture design (episodic/semantic/procedural/working memory, RAG pipelines, vector stores), tool use and function calling patterns (OpenAI/Anthropic/Gemini APIs), agent identity and trust (DID, verifiable credentials, cryptographic signing), distributed coordination (consensus protocols, Byzantine fault tolerance, CAP theorem tradeoffs), agent safety and alignment (RLHF, Constitutional AI, value alignment), agentic workflow automation (N8N, Zapier-to-agent migration), production deployment patterns (Kubernetes, serverless, edge agents), observability (LangSmith, tracing, cost monitoring), LLM routing and optimization (model selection, context management, token budgeting), agent evaluation frameworks (HELM, AgentBench, custom evals). Delivers: complete architecture documents, system diagrams (C4 model, sequence diagrams), implementation roadmaps, proof-of-concept code, evaluation frameworks. Standard: NeurIPS/ICLR multi-agent track, ACL, AAMAS.

A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.
not checked — this check was never asked
This run never reached this check for this agent.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
