Gastown is an open‑source framework that lets multiple AI coding agents, Claude Code, GitHub Copilot, Gemini and others, work side‑by‑side without losing context. It stores each agent's state in git‑backed worktrees, so crashes or restarts never erase progress, enabling reliable, scalable multi‑agent pipelines.
The open‑source "planning-with-files" stores task plans, findings, and progress in markdown on disk, letting agents survive context loss, restarts, or crashes. New v3 adds optional autonomous and gated modes that pause agents until the plan completes, enabling crash‑proof workflows for AI‑driven development pipelines.
The latest Claude Opus 4.8 and Sonnet 5 models often inject invented fields into the nested edits array when invoking Pi’s edit tool, causing schema validation failures despite generating correct edits. Armin Ronacher shows this regression is getting worse compared to older Anthropic models, exposing a growing misalignment between model outputs and tool interfaces.
