From 12d5421c266c789ab9b4577c58039172c03d0f8b Mon Sep 17 00:00:00 2001 From: sky5454 Date: Fri, 17 Apr 2026 11:17:12 +0800 Subject: [PATCH 1/2] refactor(agent): split loop.go into focused sub-packages Break up the monolithic 4384-line loop.go into 12 focused files: - loop.go: core AgentLoop struct and main Run loop - loop_turn.go: turn execution logic (runTurn, askSideQuestion, etc.) - loop_utils.go: pure utility functions (formatters, helpers) - loop_init.go: constructor and tool registration - loop_message.go: message handling (processMessage, routing) - loop_command.go: command processing (/use, /btw, etc.) - loop_mcp.go: MCP runtime management - loop_event.go: event/hook system helpers - loop_media.go: media resolution and artifact handling - loop_outbound.go: response publishing - loop_transcribe.go: audio transcription - loop_steering.go: steering queue and continuation - loop_inject.go: setter injection methods No functional changes - pure code movement with updated imports.

This is a pure refactoring with no behavioral changes. + +## Goals + +- Reduce cognitive load when navigating agent loop code +- Enable parallel work by decoupling concerns +- Maintain all existing functionality and tests +- Keep imports minimal per file + +## File Map + +| File | Lines | Responsibility | +|------|-------|----------------| +| `loop.go` | ~650 | Core `AgentLoop` struct, `Run`, `Stop`, `Close`, `ReloadProviderAndConfig`, `runAgentLoop` | +| `loop_turn.go` | ~1880 | Turn execution: `runTurn`, `abortTurn`, `selectCandidates`, `askSideQuestion`, `isolatedSideQuestionProvider`, side question model config | +| `loop_utils.go` | ~480 | Standalone utility functions: formatters, cloners, helpers (no receiver) | +| `loop_init.go` | ~355 | `NewAgentLoop` constructor and `registerSharedTools` | +| `loop_message.go` | ~300 | Message handling: `processMessage`, `processSystemMessage`, routing helpers, `ProcessDirect`, `ProcessHeartbeat` | +| `loop_command.go` | ~265 | Command processing: `handleCommand`, `applyExplicitSkillCommand`, pending skills management | +| `loop_mcp.go` | ~235 | MCP runtime: `ensureMCPInitialized`, server discovery, deferred server handling | +| `loop_event.go` | ~205 | Event system helpers: `emitEvent`, `logEvent`, `hookAbortError`, `newTurnEventScope`, `MountHook`, `SubscribeEvents` | +| `loop_media.go` | ~198 | Media resolution: `resolveMediaRefs`, artifact building, MIME detection | +| `loop_outbound.go` | ~165 | Response publishing: `PublishResponseIfNeeded`, `publishPicoReasoning`, `handleReasoning` | +| `loop_transcribe.go` | ~110 | Audio transcription: `transcribeAudioInMessage`, `sendTranscriptionFeedback` | +| `loop_steering.go` | ~97 | Steering queue: `runTurnWithSteering`, `processMessageSync`, `resolveSteeringTarget` | +| `loop_inject.go` | ~104 | Setter injection: `SetChannelManager`, `SetMediaStore`, `SetTranscriber`, `GetRegistry`, `GetConfig`, `RecordLastChannel` | + +## Core Principles Applied + +### 1. Same Package, Independent Files +All files belong to the `agent` package and compile together. This preserves the original visibility rules — no interface abstraction was introduced in this phase. + +### 2. No Logic Changes +All functions were moved verbatim (except updating import statements). The extraction script used the original `loop.go.backup` as source of truth to ensure no drift. + +### 3. Shared Types Remain in loop.go +The `AgentLoop` struct, `processOptions`, `continuationTarget`, and all hook/event types stay in `loop.go` since they are referenced across files. + +### 4. Turn State Is Central +`loop_turn.go` is the largest file because the turn lifecycle (`runTurn`) is inherently large. It contains the core LLM interaction loop, tool execution, subturn spawning, and steering injection. + +## What's Left in loop.go + +```go +// Core struct +type AgentLoop struct { ... } + +// Main lifecycle +func (al *AgentLoop) Run(ctx context.Context) error +func (al *AgentLoop) Stop() +func (al *AgentLoop) Close() +func (al *AgentLoop) ReloadProviderAndConfig(ctx, provider, cfg) + +// Turn orchestration (calls into loop_turn.go) +func (al *AgentLoop) runAgentLoop(ctx, agent, opts) (string, error) +``` + +## Extraction Method + +The split was done programmatically using Node.js to: +1. Identify function boundaries using brace counting +2. Extract each function to its target file +3. Add necessary imports to each file +4. Remove the extracted function from loop.go +5. Run `go fmt` and `go vet` to verify + +## Testing + +All existing tests pass. The 5 failing tests (`TestGlobalSkillFileContentChange` and 4 Seahorse tests) are pre-existing failures unrelated to this refactor (database file locking issues on Windows). + +Build status: `go build ./pkg/agent/...` passes with no errors. + +## Phase 2: Dependency Inversion (Planned) + +A future phase will introduce interface types to decouple `AgentLoop` from its dependencies, enabling: +- Easier testing with mock dependencies +- Alternative runtime configurations +- Cleaner boundaries for MCP and other extensions + +## See Also + +- [context.md](context.md) — context management and session handling
