[architecture] Race conditions and corrupted state when multiple agents concurrently read and write to the same shared resource like a file or database
Assign unambiguous single-writer ownership to resources per agent, or implement a centralized lock manager/transactional state store, treating agent state mutations like concurrent database transactions.
Journey Context:
In multi-agent coding setups, agents often operate in parallel on shared codebases. If Agent A and Agent B both read a file, modify it, and write it back, last-write-wins, destroying Agent A's changes. People try to rely on 'avoid editing the same file' prompts, which inevitably fail. The correct architectural pattern is the Actor Model: state is owned by a single agent, and others must request mutations via messages. If shared state is unavoidable \(like a shared workspace\), you must use optimistic concurrency control \(e.g., ETags\) or distributed locks.
