sky5454 329e68e017 refactor(agent): Agent Looper refactor phase2, restructure pipeline and rename loop files to agent (#2585)
* refactor(agent): introduce interfaces for MessageBus and ChannelManager

Phase 2 of loop.go refactor — dependency inversion using adapter pattern.

- Add interfaces.MessageBus and interfaces.ChannelManager interfaces
- Create adapters/messagebus.go wrapping *bus.MessageBus
- Create adapters/channelmanager.go wrapping *channels.Manager
- Update AgentLoop to use interfaces instead of concrete types
- Update registerSharedTools to accept interfaces.MessageBus

* refactor(agent): restructure pipeline and rename loop files

Pipeline refactoring:
- Split pipeline.go (1400 lines) into focused files:
  - pipeline_setup.go (~115 lines): SetupTurn method
  - pipeline_llm.go (~519 lines): CallLLM method
  - pipeline_execute.go (~693 lines): ExecuteTools method
  - pipeline_finalize.go (~78 lines): Finalize method
- Pipeline struct and NewPipeline remain in pipeline.go (~39 lines)

Agent file renaming:
- Rename loop_*.go to agent_*.go for consistent naming:
  - loop.go -> agent.go, loop_message.go -> agent_message.go, etc.
- Merge turn.go + turn_exec.go into turn_state.go
- Rename loop_turn.go -> turn_coord.go

Documentation:
- Update docs/pipeline-restructuring-plan.md
- Add docs/agent-rename-plan.md

Architecture

Internal architecture notes for major runtime mechanisms and subsystem design.

  • Steering: injecting messages into a running agent loop between tool calls.
  • SubTurn Mechanism: sub-agent coordination, concurrency control, and lifecycle handling.
  • Session System: session scope allocation, JSONL persistence, alias compatibility, and migration. (ZH)
  • Routing System: agent dispatch, session policy selection, and light/heavy model routing. (ZH)
  • Hook System Guide: current hook architecture and protocol details.
  • Agent Refactor: notes and checkpoints for the agent refactor work.
