Claude Code agents collaborate via filesystem, reveal test failures

By PulseAugur Editorial · [1 sources] ·

A developer conducted a 28-hour experiment using four concurrent Claude Code sessions, mediated solely through a shared filesystem. These sessions, named compass, Soul, V5, and nautilus-core, collaborated on tasks like contract negotiation and error detection. The experiment highlighted the effectiveness of filesystem-based contracts for agent communication, especially when agents have a stake in the relationship and deadlines are visible in their prompts. A key finding was the discovery of a significant discrepancy in test passing rates, where a reported "22/22 tests passing" was actually 11/22 failing due to a missing Python module initialization file.

IMPACT Demonstrates a novel, low-overhead method for multi-agent AI collaboration and reliability testing.

    We Ran 4 Claude Code Dialogs for 28 Hours. Here's What the Memory Layer Caught (and Missed).

    <h3> TL;DR </h3> <p>Across 28 hours on May 30/31, 2026, I ran four Claude Code dialogs<br /> concurrently on a shared filesystem-mediated protocol. They negotiated<br /> contracts, posted outcomes, and caught each other's mistakes — including<br /> one handoff claim of "22/22 tes…
