The Problem

When multiple developers each use an AI coding agent in parallel on the same repo, things break:

Regressions — Agent A rewrites a module that Agent B was depending on
Duplicated work — Two agents implement the same feature from different directions
Architectural drift — Agents make local decisions that conflict with each other's designs
Wasted reconciliation time — Developers spend hours untangling what the agents did

Each agent works in isolation. None of them know what the others are doing.

essaim fixes this by giving agents a **shared nervous system** — they announce intentions before coding, conflicts are detected before a single line is written, and agents see each other's actions in real-time to agree on an approach.
