Archon Error Classification System for Isolation Operations

April 10, 2026 coleam00/Archon ↗

Archon centralizes isolation failure handling in packages/isolation/src/errors.ts, where low-level infrastructure errors are classified into user-friendly messages or escalated as crashes depending on their recognition status.

The coleam00/Archon repository implements a sophisticated error classification system to manage failures during AI-driven workflow isolation. When creating or reusing Git worktree environments, the system encounters infrastructure issues ranging from file-system permission denials to disk-space exhaustion. Rather than exposing raw stack traces to users, Archon transforms these exceptions through a centralized classification layer that maintains both user experience quality and debugging safety.
