    Author 12-Factor Agent satellite: production methodology layered above mechanism patterns; HumanLayer/Horthy framing; stateless-reducer sketch; reducer-purity gotcha.

    @julianken

  2. ADDEDStreaming

    Author Streaming satellite: SSE event-flow, token vs structured vs tool-call variants, mid-stream-error gotcha.

    @julianken

  8. ADDEDA2A

    Author A2A satellite: Agent Card discovery, Task lifecycle, distinction from MCP and in-process Handoffs.

    @julianken

  9. ADDEDMulti-Agent Debate

    Author Multi-Agent Debate satellite: parallel-agent answers, peer-critique rounds, deterministic aggregation; degeneration-of-thought gotcha.

    @julianken

    @julianken

  11. ADDEDOrchestrator-Workers

    Author Orchestrator-Workers satellite: hub-and-spoke planner/worker/aggregator topology, AutoGen/MetaGPT/Claude-Research framing, token-multiplier gotcha.

    @julianken

  12. ADDEDHandoffs / Swarm

    Author Handoffs / Swarm satellite: sequential conversation ownership, transfer-as-tool-call, supervisor variant.

    @julianken

  13. ADDEDGuardrails

    Author Guardrails satellite: input/output rails, layered defence, indirect-prompt-injection gotcha.

    @julianken

  14. ADDEDCheckpointing

    Author Checkpointing satellite: durable agent state across crashes; snapshot vs replay variants; determinism gotcha.

    @julianken

  15. ADDEDContext Engineering
