refactor(core): extract CLI logic into adapter pattern#242
Merged
Conversation
Simplify invokeAgent by moving provider-specific logic into independent adapter modules. Each CLI backend (Claude, Codex, OpenCode) now implements a standardized AgentAdapter interface and registers automatically via a provider registry. This reduces invoke.ts from ~400 lines to ~190, improves testability, and makes it straightforward to add new CLI backends. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Description
Extract provider-specific CLI invocation logic from
invoke.tsinto independent adapter modules. Each CLI backend (Claude, Codex, OpenCode) now implements a standardizedAgentAdapterinterface and auto-registers via a provider registry.This refactoring reduces
invoke.tsfrom ~400 to ~190 lines, improves testability, and simplifies adding new CLI backends—just create a new adapter file and callregisterAdapter().Changes
