-# Refactor 343: Abstract agent runtime to support non-Claude-Code backends
-
-## Current State
-
-- TBD
-
-## Desired State
-
-Currently agent spawning is tightly coupled to Claude Code CLI — agents are spawned as PTY processes running the `claude` binary. To support ChatGPT and Gemini as agent backends, we need to abstract the agent runtime.
-
-The agent pool currently does:
-1. Spawn `claude` CLI process via portable-pty
-2. Stream JSON events from stdout
-3. Parse tool calls, text output, thinking traces
-4. Wait for process exit, run gates
-
-This needs to become a trait so different backends can be plugged in:
-- Claude Code (existing) — spawns `claude` CLI, parses JSON stream
-- OpenAI API — calls ChatGPT via API with tool definitions, manages conversation loop
-- Gemini API — calls Gemini via API with tool definitions, manages conversation loop
-
-The key abstraction is: an agent runtime takes a prompt + tools and produces a stream of events (text output, tool calls, completion). The existing PTY/Claude Code logic becomes one implementation of this trait.
-
-## Acceptance Criteria
-
-- [ ] Define an AgentRuntime trait with methods for: start, stream_events, stop, get_status
-- [ ] ClaudeCodeRuntime implements the trait using existing PTY spawning logic
-- [ ] Agent pool uses the trait instead of directly spawning Claude Code
-- [ ] Runtime selection is configurable per agent in project.toml (e.g. runtime = 'claude-code')
-- [ ] All existing Claude Code agent functionality preserved
-- [ ] Event stream format is runtime-agnostic (text, tool_call, thinking, done)
-- [ ] Token usage tracking works across runtimes
