Pattern: Fan-Out Investigation — Lead Agent Delegates to Parallel Specialists on Shared Filesystem

Anthropic·medium signal

Claude's new multi-agent orchestration formalizes a pattern seen in production agent systems: a lead agent decomposes a task and fans out to specialists (each with its own model, prompt, and tools) that work in parallel on a shared filesystem. Persistent event logs enable mid-workflow check-ins. The architecture maps directly to incident response (deploy history, error logs, metrics, support tickets) and codebase investigation (tests, types, docs, git history).
