Pi Durable Dev Rules

@earendil-works/pi-durable is a durable agent harness: conversations, model turns, tool calls, tasks, and your own documents are committed to storage before anything is shown, so a process that dies mid-turn is picked up where it stopped. It ships in the pi monorepo next to @earendil-works/pi-ai (model access, tools, messages) and @earendil-works/chord (tracked JSON state).

Two things about it decide most design choices:

• The API is experimental. Version 1.2.0 tracks the monorepo; breaking changes land in every release. Quote and write against the version you have installed, and treat a signature difference as a version difference rather than a mistake.
• It is a library for building agentic applications, not a coding-agent CLI. For the Pi CLI, its extensions, skills, MCP, and SDK, use the sibling skill pi-dev-rules.
