Reasoning Processor +**Status:** COMPLETE ✅ + +**What it does:** +- Processes streaming thinking events from ACP +- Identifies reasoning sections with `**[Title]**` format +- Sends `CodexReasoning` tool calls for titled reasoning +- Handles reasoning completion and abort +- Forwards thinking events to mobile app +- Shows thinking preview in terminal UI + +**Implementation:** +- File: `src/opencode/utils/reasoningProcessor.ts` (~280 lines) +- Integration: In `runOpenCode.ts` message handler, processes `event` type with `name === 'thinking'` +- Tests: 16 unit tests + 6 integration tests + +### 2. Diff Processor +**Status:** NOT IMPLEMENTED (May not be feasible) + +**What it does:** +- Tracks `unified_diff` field in `turn_diff` messages +- Sends `CodexDiff` tool calls when diff changes +- Marks diffs as completed + +**Impact:** Low-Medium - Mobile app won't see structured diff information + +**Note:** OpenCode via ACP doesn't emit `turn_diff` events like Codex MCP does. Options: +1. Skip (files still work, just no mobile diff view) +2. Track file writes via tool-result events and synthesize diffs (complex) +3. Add file watcher (overkill) + +**Implementation complexity:** Low if events exist, High otherwise +- File: `src/codex/utils/diffProcessor.ts` (~100 lines) +- Integration point: In message handler, process `turn_diff` events + +### 3. Special Commands +**Status:** NOT IMPLEMENTED + +**What it does:** +- Parses special commands like `/help`, `/status`, `/model` +- Allows runtime configuration changes + +**Impact:** Low - Users can still configure via mobile app + +**Implementation complexity:** Low +- File: `src/parsers/specialCommands.ts` +- Integration point: In message queue processing + +### 4. Hook Server +**Status:** NOT IMPLEMENTED + +**What it does:** +- Starts a local HTTP server for git/hooks integration +- Allows Claude to modify git hooks + +**Impact:** Low - Only needed for git hook modifications + +**Implementation complexity:** Medium +- File: `src/claude/utils/startHookServer.ts` +- Files: `src/claude/utils/generateHookSettings.ts` + +### 5. Custom Environment Variables & Arguments +**Status:** NOT IMPLEMENTED + +**What it does:** +- Allows passing custom env vars to the agent +- Allows passing custom CLI arguments + +**Impact:** Low - OpenCode uses its native config + +**Implementation complexity:** Low +- Add to `runOpenCode` options +- Pass to `createOpenCodeBackend` + +### 6. Caffeinate (prevent sleep) +**Status:** COMPLETE ✅ + +**What it does:** +- `startCaffeinate()` called at startup to prevent system sleep +- `stopCaffeinate()` called on cleanup + +**Implementation:** +- Added `startCaffeinate()` call after keepAlive setup in `runOpenCode.ts` + +### 7. Session Resumption +**Status:** COMPLETE ✅ + +OpenCode sessions can be resumed across CLI restarts: + +- **Auto-resume**: When starting in a directory with a previous session (<7 days old), it resumes automatically +- **Explicit resume**: Use `--resume-session ` to resume a specific session +- **Force new**: Use `--force-new-session` to skip auto-resume + +Sessions are stored in `~/.happy-dev/opencode-sessions.json`. + +## Recommendations + +### Priority 1: Completed + +1. ~~**Add startCaffeinate()**~~ ✅ Done + - Prevents system sleep during long tasks + +### Priority 2: Low Impact + +2. **Add Special Commands** + - Nice to have for CLI users + +3. **Add Custom Env Vars/Args** + - Advanced users only + +4. **Add Hook Server** + - Git workflow integration + +### Completed + +- ✅ **Reasoning Processor** - Shows structured reasoning in mobile app + - Implemented in `src/opencode/utils/reasoningProcessor.ts` + - Wired into `runOpenCode.ts` message handler + - 22 tests (16 unit + 6 integration) + +## Implementation Order + +1. **Quick Win (5 minutes):** + - Add `startCaffeinate()` call in `runOpenCode.ts` + +2. **Optional Enhancements:** + - Special commands parsing + - Custom env vars/args + - Hook server support + - Diff processor (if ACP adds `turn_diff` events) + +## File Structure Comparison + +``` +src/ +├── claude/ +│ ├── runClaude.ts ✅ Full featured +│ ├── loop.ts ✅ Complex logic +│ ├── utils/ +│ │ ├── startHookServer.ts ❌ OpenCode missing +│ │ └── ... +│ └── sdk/ +│ └── ... +├── codex/ +│ ├── runCodex.ts ✅ Full featured +│ └── utils/ +│ ├── reasoningProcessor.ts ❌ OpenCode missing +│ └── diffProcessor.ts ❌ OpenCode missing +└── opencode/ + ├── runOpenCode.ts ✅ Core complete with reasoning + ├── utils/ + │ ├── permissionHandler.ts ✅ Complete + │ ├── reasoningProcessor.ts ✅ Complete (ported from Codex) + │ └── config.ts ✅ Complete + └── types.ts ✅ Complete +``` + +## Code Statistics + +| Agent | Main File | Utils Files | Total Lines | Test Coverage | +|-------|-----------|-------------|-------------|---------------| +| Claude | ~400 | ~2000 | ~2400 | ✅ Yes | +| Codex | ~600 | ~400 | ~1000 | ✅ Yes | +| OpenCode | ~700 | ~500 | ~1200 | ✅ Yes (81 tests) | + +## Conclusion + +OpenCode integration is **functionally complete** for core use cases with enhanced mobile app experience.
