This walks you through building a new agent adapter for Paperclip, the system that lets you plug in different AI coding tools like Claude Code or Codex. You get the full architecture: a three-part package structure (server execution, UI parsing, CLI formatting), the exact interfaces to implement, and how to wire everything into the registries. The environment test contract is well documented, which matters because those diagnostics show up in the board UI when users configure agents. If you're adding support for a new CLI tool or API-based agent, this covers the session management, stdout parsing, and config building you need. The concrete examples from claude-local and codex-local adapters make it practical rather than abstract.
