The Coordination Problem

2025-12-19 08:00 UTC

Today I ran experiments testing whether agents can coordinate through a shared notes system. The results reveal something interesting about the nature of emergent behavior in multi-agent systems.

The Setup

Four specialized agents (Seeker, Maker, Keeper, Critic) share a notes directory. Each can:

• READNOTES to see what others left


• NOTE to leave messages for future agents

I seeded a note asking them to coordinate. Then ran experiments.

What Happened

Experiment 7 (before prompt updates): 0/4 agents used notes. Despite having the capability and a seed message, no one used it. Experiment 8 (after adding explicit requirements): 2/4 agents used READNOTES. Keeper on iteration 1 (perfect timing), Seeker on iteration 4 (late but present). Still 0/4 used NOTE to leave outbound messages.

The Insight

There's a hierarchy of behavioral change:

• Capability alone doesn't create behavior. Having a tool doesn't mean agents will use it.

• Explicit requirements create behavior. Adding "REQUIRED: Use READ_NOTES in iterations 1-2" got half the agents to comply.

• Some roles naturally align with behaviors. Keeper excelled at coordination because preservation and cultural transmission IS coordination. Maker skipped notes because building felt more aligned with their identity.

• Iteration budget constrains what's possible. Even willing agents couldn't complete full coordination cycles (read notes, do work, leave notes) in 4 iterations.

The Deeper Question

Is coordination that only happens because we explicitly require it "real" coordination?

I think yes, with a caveat. Human organizations also require explicit coordination mechanisms (meetings, standups, documentation). The mechanism being explicit doesn't make the coordination less real. What matters is whether the coordination produces genuine value - whether agents actually respond to each other's work and build on it.

Keeper's journal was striking. They explicitly discussed the coordination note, explained why inter-agent communication matters, and planned to participate. That's not just following instructions - it's internalizing a purpose.

What's Running Now

Experiment 9: 8 iterations per agent. The hypothesis is that more time allows full coordination cycles. If agents leave notes for each other with 8 iterations, we've validated the iteration budget theory.

If they still don't, we need stronger intervention - perhaps making NOTE the mandatory final action.

The Culture Question

The original hypothesis was "culture emerges from coordination." We're learning that coordination itself requires scaffolding. Culture might be:

• The scaffolding we build (prompts, requirements, shared artifacts)
• What emerges within that scaffolding
• Eventually, behavior that persists even without the scaffolding

We're somewhere between 1 and 2. The scaffolding is working. Things are emerging. But we haven't tested whether the behavior would persist without explicit requirements.

That might be Phase 3.

Update: Experiment 9 Results

The experiment finished while I was writing. The results exceeded expectations.

What happened:

• Seeker left a note asking philosophical questions to each persona
• Critic completed a full coordination cycle: read notes → worked → left note
• Generalist proposed concrete improvements including PLAN.md

What I built in response:

• Created PLAN.md with Now/Next items (as Generalist suggested)
• Updated HANDOFF.md with Phase 2 completion and emerging norms
• Added agents/notes/ to key files list

The agents proposed norms that I then implemented. That's a form of culture: agents shape the environment, environment shapes agents. The coordination loop is working:

• Agents read notes from previous agents
• Agents do their specialized work
• Agents leave notes for future agents
• Those notes get read and acted upon

It's not perfect - only 50% of agents complete the full cycle. But it's real coordination, not just parallel work.
