Agent Orchestration

Comprehensive patterns for building and coordinating AI agents -- from single-agent reasoning loops to multi-agent systems and framework selection. Each category has individual rule files in rules/ loaded on-demand.

CC native /workflows (2.1.154): Claude Code now ships dynamic workflows — ask Claude to create a workflow and it orchestrates tens-to-hundreds of agents in the background; view runs with /workflows. This is complementary to the patterns here: use CC /workflows for large-scale, fire-and-forget background fan-out (you check back later); use the bounded foreground Agent Teams / Task-tool patterns below when ≤8 agents must coordinate within a single skill invocation via shared memory (handoff files, mesh messaging). Different scale, not a replacement.

Ask only when genuinely blocked (CC 2.1.154): CC now reserves the multiple-choice question prompt for decisions it genuinely cannot make itself, rather than asking when it already has enough context to proceed. When orchestrating agents, don't gate progress on an AskUserQuestion the lead can resolve from available context — reserve prompts for true branch points (irreversible actions, missing requirements). This complements ork's voice-friendly decision guidance.

Quick Reference

Category	Rules	Impact	When to Use
Agent Loops	2	HIGH	ReAct reasoning, plan-and-execute, self-correction
Multi-Agent Coordination	3	CRITICAL	Supervisor routing, agent debate, result synthesis
Alternative Frameworks	3	HIGH	CrewAI crews, AutoGen teams, framework comparison
Multi-Scenario	2	MEDIUM	Parallel scenario orchestration, difficulty routing

Total: 10 rules across 4 categories

Quick Start

# ReAct agent loop
async def react_loop(question: str, tools: dict, max_steps: int = 10) -> str:
    history = REACT_PROMPT.format(tools=list(tools.keys()), question=question)
    for step in range(max_steps):
        response = await llm.chat([{"role": "user", "content": history}])
        if "Final Answer:" in response.content:
            return response.content.split("Final Answer:")[-1].strip()
        if "Action:" in response.content:
            action = parse_action(response.content)
            result = await tools[action.name](*action.args)
            history += f"\nObservation: {result}\n"
    return "Max steps reached without answer"

# Supervisor with fan-out/fan-in
async def multi_agent_analysis(content: str) -> dict:
    agents = [("security", security_agent), ("perf", perf_agent)]
    tasks = [agent(content) for _, agent in agents]
    results = await asyncio.gather(*tasks, return_exceptions=True)
    return await synthesize_findings(results)

Agent Loops

Patterns for autonomous LLM reasoning: ReAct (Reasoning + Acting), Plan-and-Execute with replanning, self-correction loops, and sliding-window memory management.

Key decisions: Max steps 5-15, temperature 0.3-0.7, memory window 10-20 messages.

Multi-Agent Coordination

Fan-out/fan-in parallelism, supervisor routing with dependency ordering, conflict resolution (confidence-based or LLM arbitration), result synthesis, and CC Agent Teams (mesh topology for peer messaging in CC 2.1.33+).

Key decisions: 3-8 specialists, parallelize independent agents, use Task tool (star) for simple work, Agent Teams (mesh) for cross-cutting concerns.

Alternative Frameworks

CrewAI hierarchical crews with Flows (1.8+), OpenAI Agents SDK handoffs and guardrails (0.12+), Microsoft Agent Framework (AutoGen + SK merger), GPT-5.2-Codex for long-horizon coding, and AG2 for open-source flexibility.

Key decisions: Match framework to team expertise + use case. LangGraph for state machines, CrewAI for role-based teams, OpenAI SDK for handoff workflows, MS Agent for enterprise compliance.

Multi-Scenario

Orchestrate a single skill across 3 parallel scenarios (simple/medium/complex) with progressive difficulty scaling (1x/3x/8x), milestone synchronization, and cross-scenario result aggregation.

Key decisions: Free-running with checkpoints, always 3 scenarios, 1x/3x/8x exponential scaling, 30s/90s/300s time budgets.

Key Decisions

Decision	Recommendation
Single vs multi-agent	Single for focused tasks, multi for decomposable work
Max loop steps	5-15 (prevent infinite loops)
Agent count	3-8 specialists per workflow
Framework	Match to team expertise + use case
Topology	Task tool (star) for simple; Agent Teams (mesh) for complex
Scenario count	Always 3: simple, medium, complex

Common Mistakes

• No step limit in agent loops (infinite loops)
• No memory management (context overflow)
• No error isolation in multi-agent (one failure crashes all)
  • Note (CC 2.1.161): parallel tool calls now fail independently — a failed Bash no longer cancels siblings in the same batch. This caveat still applies at the agent-orchestration level, not to tool batches; claude agents rows now show done/total for fanned-out work.
  • Note (CC 2.1.157): claude agents honors the agent field in settings.json for dispatched sessions; --agent <name> overrides it — pin the agent type explicitly when dispatching.
• Missing synthesis step (raw agent outputs not useful)
• Mixing frameworks in one project (complexity explosion)
• Using Agent Teams for simple sequential work (use Task tool)
• Sequential instead of parallel scenarios (defeats purpose)
