No LLM output is parsed. + + Gap B — ``Agent.from_instance`` class resolution. + Resolve all ``@agent``-decorated METHODS on an object instance into + Agent objects, attaching ``@tool`` / ``@guardrail`` methods on the same + object, wiring sub-agents by name, and supporting method bodies that + return None (attrs only), a str (dynamic instructions), or an Agent. + + Validated structurally (in-process) plus a ``plan()`` round-trip against + the live server.

When the planner judges it has enough +evidence, it picks the ``finalize_disposition`` action — that tool's +output flips a ``finalized`` flag and the DO_WHILE exits. + +The loop demonstrates the canonical PAE meta-planning pattern: +**iteration N+1's plan depends on the actual findings of iteration N**. +There's no fixed investigation cascade — the agent's next query is +genuinely conditional on what the prior queries returned, and on the +red-flag taxonomy applied so far. + +What you'll see: + * ONE workflow ID for the whole investigation. + * planner_llm__N / plan_and_compile__N / plan_exec__N / ... task + suffixes per iteration. + * Case-file state accumulates in workflow.variables across iterations. + * Termination on whichever iteration the planner emits + ``finalize_disposition``. + +Requirements: + - AGENTSPAN_SERVER_URL=http://localhost:8080/api (default) + - AGENTSPAN_LLM_MODEL=openai/gpt-4o-mini (default) + - LLM key for the chosen model. +""" + +import json +import os +import re +import sys +import time + +import requests + +from conductor.ai.agents import AgentRuntime, plan_execute, tool + +SERVER_URL = os.environ.get("AGENTSPAN_SERVER_URL", "http://localhost:8080/api") +BASE = SERVER_URL.rstrip("/").replace("/api", "") +MODEL = os.environ.get("AGENTSPAN_LLM_MODEL", "anthropic/claude-sonnet-4-6") +MAX_ITER = int(os.environ.get("AGENTSPAN_AML_MAX_ITER", "10")) +WORKFLOW_NAME = "aml_sar_investigation_loop" +WORKFLOW_VERSION = 5 + + +def _model_split(model: str) -> tuple[str, str]: + if "/" in model: + provider, name = model.split("/", 1) + return provider, name + return "openai", model + + +PROVIDER, MODEL_NAME = _model_split(MODEL) + + +# ── Synthetic alert and evidence corpus ────────────────────────── +# The investigation is set up so the LLM has to actually consult multiple +# sources: the structuring pattern in transactions is a red flag, but +# without the KYC baseline (expected behavior) + the counterparty graph +# (single overseas destination) + adverse media (sector-specific +# trade-based ML reports) the case isn't airtight.

Every message +you type is sent into the agent's Workflow Message Queue via +runtime.send_message(); the agent dequeues it, thinks, and pushes a reply back +via a tool call. The session stays alive across as many turns as you want — +the agent is a persistent running workflow, not a one-shot call. + +Key WMQ concept — bidirectional conversation loop: + The agent uses wait_for_message_tool to receive user input and reply_to_user + (a @tool backed by filesystem IPC) to send responses back. There is no + streaming, no polling for SSE events — the main thread simply blocks on a + sentinel file written by the reply_to_user worker, reads the reply, and + prompts again. Workers run as separate OS processes so the reply is + communicated via the shared filesystem rather than an in-process queue. + +Resume support: + The REPL saves the execution_id to a session file on start. On subsequent + runs, pass ``--resume`` to reconnect to the same workflow. ``resume()`` + fetches the workflow from the server, extracts the worker domain from + ``taskToDomain``, and re-registers tools under that domain — so stateful + agents resume correctly.

Fixed rotations produce fixed thinking. + +That is the random strategy. Each turn, a random agent is selected. No pattern. No schedule. The same agent might go twice in a row, or not at all for three turns. The randomness creates variety in perspective that a fixed rotation cannot. + +## What is Agentspan + +Agentspan is an orchestration layer for building, bringing, and observing AI agents as durable workflows. + +- **Build**: define agents with the Agentspan SDK using Agent, @tool, and 8 multi-agent strategies. Compiles to server-side workflows that survive crashes. +- **Bring**: already using an agent framework such as LangGraph, OpenAI Agents SDK, or Google ADK? Pass your agents directly to run(). Agentspan adds durability and orchestration on top. +- **Observe**: every execution is inspectable in the dashboard. See agent flows, inputs/outputs, tool calls, and token usage. Debug failures, replay runs. + +## Setup + +Two commands: + +```bash +pip install conductor-agent-sdk +agentspan server start +``` + +This gives you a local Agentspan server with a visual dashboard at localhost:8080. + +## What we are building + +A brainstorming session with three thinkers: + +1. **Creative**: bold, unconventional ideas — "what if we did the opposite?" +2. **Practical**: feasibility, timelines, resources — "what would it actually take?" +3. **Critical**: risks, holes, blind spots — "what could go wrong?" + +Each turn, one is randomly selected. After 6 turns, a summarizer distills the session into the top ideas and next steps. + +``` +Turn 1: [Creative] <- random +Turn 2: [Critical] <- random +Turn 3: [Creative] <- random (again!) +Turn 4: [Practical] <- random +Turn 5: [Critical] <- random +Turn 6: [Practical] <- random + | + [Summarizer] -> top 3 ideas + next step +``` + +## How is this different from round robin? + +In **round robin** (Part 6), the order is fixed: A, B, C, A, B, C. Every agent gets equal time. Every agent knows when their turn is. + +In **random**, there is no order. Agent A might speak three times. Agent C might speak once. The distribution is uneven by design — some perspectives naturally dominate in any real brainstorming session, and that is fine. + +| | Round Robin | Random | +|---|---|---| +| Selection | Fixed rotation | Random each turn | +| Equal participation | Guaranteed | Not guaranteed | +| Predictable | Yes | No | +| Best for | Structured debate, reviews | Brainstorming, creative exploration | + +## Defining the thinkers + +Three agents with deliberately different thinking styles: + +```python +from conductor.ai.agents import Agent, AgentRuntime, Strategy + + +creative = Agent( + name="creative", + model="openai/gpt-4o", + instructions=( + "You are a creative thinker. Generate bold, unconventional ideas. " + "Push boundaries. Think 'what if we did the opposite of what everyone " + "expects?' Read what others said before you and build on their ideas " + "or take them in a surprising direction. Keep your response to 2-3 paragraphs." + ), +) + +practical = Agent( + name="practical", + model="openai/gpt-4o", + instructions=( + "You are a practical thinker. Focus on what can actually be built " + "and shipped. Consider timelines, resources, and feasibility. Read " + "what others said before you and ground their ideas in reality — " + "what would it take to actually do this? Keep your response to 2-3 paragraphs." + ), +) + +critical = Agent( + name="critical", + model="openai/gpt-4o", + instructions=( + "You are a critical thinker. Find the holes, the risks, the things " + "nobody wants to talk about. Read what others said before you and " + "stress-test their ideas — what could go wrong? What are they not " + "considering? Keep your response to 2-3 paragraphs." + ), +) +``` + +The key instruction in each: "Read what others said before you." Each agent sees the full conversation. The difference from round robin is that who speaks next is random, not predetermined. + +## The summarizer + +After the brainstorm, a summarizer produces actionable output: + +```python +summarizer = Agent( + name="summarizer", + model="openai/gpt-4o", + instructions=( + "You observed a brainstorming session between a creative thinker, " + "a practical thinker, and a critical thinker. Produce a summary:\n\n" + "1. Top 3 ideas (ranked by potential)\n" + "2. Biggest risk identified\n" + "3. Recommended next step (one sentence)\n\n" + "Be concise and actionable." + ), +) +``` + +## The random strategy + +```python +brainstorm = Agent( + name="brainstorm", + model="openai/gpt-4o", + agents=[creative, practical, critical], + strategy=Strategy.RANDOM, + max_turns=6, +) + +pipeline = brainstorm >> summarizer +``` + +`max_turns=6` means 6 randomly selected turns. Some agents might go multiple times, others might be skipped entirely. Then `>>` pipes the brainstorm transcript to the summarizer. + +Compare the strategies: + +```python +# Sequential: fixed order, each runs once +pipeline = a >> b >> c + +# Parallel: all run at once +team = Agent(agents=[a, b, c], strategy=Strategy.PARALLEL) + +# Handoff: parent LLM picks one +triage = Agent(agents=[a, b, c], strategy=Strategy.HANDOFF) + +# Router: classifier picks one +triage = Agent(agents=[a, b, c], strategy=Strategy.ROUTER, router=classifier) + +# Swarm: agents transfer between each other +team = Agent(agents=[a, b, c], strategy=Strategy.SWARM) + +# Round robin: fixed rotation +debate = Agent(agents=[a, b, c], strategy=Strategy.ROUND_ROBIN, max_turns=6) + +# Random: random selection each turn +brainstorm = Agent(agents=[a, b, c], strategy=Strategy.RANDOM, max_turns=6) +``` + +Same `Agent` class. Different strategy. Different behavior. + +## Running it + +```python +with AgentRuntime() as runtime: + result = runtime.run( + pipeline, + "How should a developer tools company get its first 1,000 users?", + ) + result.print_result() +``` + +Every run produces a different conversation because the agent selection is random. Run it twice and you get two different brainstorming sessions. That is the point. + +## When to use random + +Random is not a strategy for everything. It is specifically useful when: + +- **Brainstorming** — you want diverse, unpredictable perspectives +- **Load balancing across models** — distribute prompts across GPT-4o, Claude, Gemini randomly to compare output quality +- **Stress testing** — randomly select different scenarios to hit an agent with +- **Creative writing** — different voices or styles contribute randomly to a collaborative piece + +If you need every agent to participate equally, use round robin. If you need one specific agent, use handoff or router. Random is for when variety itself is the goal. + +## How durability works + +The random selection is made server-side and persisted. If your process crashes after turn 4: + +1. Turns 1–4 and their random selections are persisted on the server. +2. You restart your script. +3. Turns 5–6 continue with new random selections — the first 4 are not re-run. + +## Composability + +Random composes with other strategies: + +```python +# Random brainstorm, then structured review +brainstorm = Agent(agents=[creative, practical, critical], strategy=Strategy.RANDOM, max_turns=6) +review = Agent(agents=[architect, security], strategy=Strategy.ROUND_ROBIN, max_turns=4) + +pipeline = brainstorm >> review >> summarizer +``` + +Random generates ideas.
