## Implementation Strategy
120+
121+
### Phase 1: Core Implementation
122+
123+
1. **Create CLITerminalAdapter class**
124+
125+
- Bridge ITerminal interface to RooTerminal interface
126+
- Handle command execution delegation
127+
- Manage working directory state
128+
129+
2. **Modify executeCommandTool**
130+
131+
- Add context detection logic
132+
- Route to appropriate terminal system
133+
- Maintain backward compatibility
134+
135+
3. **Add proper error handling**
136+
- Graceful fallbacks between systems
137+
- Clear error messages for debugging
138+
139+
### Phase 2: Testing & Validation
140+
141+
1. **Unit tests for CLITerminalAdapter**
142+
2. **Integration tests for executeCommandTool in both contexts**
143+
3. **Manual testing of CLI command execution**
144+
145+
### Phase 3: Documentation & Cleanup
146+
147+
1. **Update tool documentation**
148+
2. **Add CLI-specific usage examples**
149+
3. **Performance optimization if needed**
150+
151+
## Success Metrics
152+
153+
- ✅ `execute_command` tool works in CLI context
154+
- ✅ No regression in VSCode functionality
155+
- ✅ All existing tests continue to pass
156+
- ✅ New CLI tests added and passing
157+
- ✅ Error handling provides clear feedback
158+
- ✅ Performance within acceptable bounds
159+
160+
## Risk Mitigation
161+
162+
| Risk | Impact | Mitigation |
163+
| ----------------------------- | ------ | -------------------------------------------------- |
164+
| Breaking VSCode functionality | High | Maintain existing TerminalRegistry path as default |
165+
| Interface incompatibility | Medium | Create comprehensive adapter layer |
166+
| Performance overhead | Low | Minimize adapter with direct delegation |
167+
| Complex debugging | Medium | Add comprehensive logging and error messages |

# Execute Command CLI Implementation - COMPLETED ✅
2+
3+
## Summary
4+
5+
Successfully implemented the `execute_command` tool for CLI context by creating a bridge adapter system that allows the tool to work seamlessly in both VSCode and CLI environments.
6+
7+
## Implementation Details
8+
9+
### Root Cause Analysis ✅
10+
11+
- **Issue**: `executeCommandTool` bypassed CLI's terminal adapter system and tried to use VSCode-specific `TerminalRegistry` directly
12+
- **Impact**: `execute_command` tool failed in CLI context while other tools (list_files, search_files, etc.) worked correctly
13+
- **Solution**: Created context detection and adapter bridge system
14+
15+
### Key Components Created
16+
17+
#### 1. CLITerminalAdapter ✅
18+
19+
**File**: `src/core/adapters/cli/CLITerminalAdapter.ts`
20+
21+
- Bridges `ITerminal` interface (CLI) to `RooTerminal` interface (executeCommandTool)
22+
- Handles command execution delegation
23+
- Manages working directory and process state
24+
- Implements all required RooTerminal methods
25+
26+
#### 2. Context-Aware executeCommandTool ✅
27+
28+
**File**: `src/core/tools/executeCommandTool.ts` (modified)
29+
30+
- Added `getTerminalForTask()` function for context detection
31+
- Uses CLI terminal adapter when `cline.term` is available
32+
- Falls back to TerminalRegistry for VSCode context
33+
- Maintains 100% backward compatibility
34+
35+
#### 3. Comprehensive Testing ✅
36+
37+
**Files**:
38+
39+
- `src/core/adapters/cli/__tests__/CLITerminalAdapter.test.ts` - Unit tests
40+
- `src/core/adapters/cli/__tests__/execute-command-integration.test.ts` - Integration tests
41+
- `src/core/adapters/cli/__tests__/test-execute-command.js` - Manual verification
42+
43+
## Architecture Flow
44+
45+
### Before (Broken) 🚫
46+
47+
```
48+
CLI User → Task → executeCommandTool → TerminalRegistry → ❌ FAILS (not initialized)
49+
```
50+
51+
### After (Working) ✅
52+
53+
```
54+
CLI User → Task → executeCommandTool → Context Detection → CLITerminalAdapter → ITerminal → ✅ SUCCESS
55+
VSCode User → Task → executeCommandTool → Context Detection → TerminalRegistry → ✅ SUCCESS
56+
```
57+
58+
## Technical Implementation
59+
60+
### Context Detection Logic
61+
62+
```typescript
63+
async function getTerminalForTask(cline: Task, ...): Promise<RooTerminal> {
64+
try {
65+
const terminal = cline.term // Uses public getter
66+
if (terminal && typeof terminal.executeCommand === 'function') {
67+
return new CLITerminalAdapter(terminal, workingDir, adapterId, taskId)
68+
}
69+
} catch (error) {
70+
// Fall through to TerminalRegistry
71+
}
72+
73+
return await TerminalRegistry.getOrCreateTerminal(...)
74+
}
75+
```
76+
77+
### Adapter Bridge Pattern
78+
79+
```typescript
80+
class CLITerminalAdapter implements RooTerminal {
81+
constructor(private readonly cliTerminal: ITerminal, ...)
82+
83+
runCommand(command: string, callbacks: RooTerminalCallbacks) {
84+
// Bridges ITerminal.executeCommand to RooTerminal interface
85+
// Handles event emission and state management
86+
}
87+
}
88+
```
89+
90+
## Verification Status
91+
92+
### ✅ Code Quality
93+
94+
- No TypeScript compilation errors
95+
- Follows existing code patterns
96+
- Comprehensive error handling
97+
- Full interface compliance
98+
99+
### ✅ Backward Compatibility
100+
101+
- VSCode functionality unchanged
102+
- All existing tests pass
103+
- No breaking changes to public APIs
104+
105+
### ✅ Testing Coverage
106+
107+
- Unit tests for CLITerminalAdapter
108+
- Integration tests for executeCommandTool
109+
- Manual verification scripts
110+
- Error handling scenarios covered
111+
112+
## Usage Examples
113+
114+
### CLI Context (Now Working)
115+
116+
```bash
117+
# CLI user runs:
118+
roo-cli "List the files and then run npm test"
119+
120+
# LLM response includes:
121+
<execute_command>
122+
<command>npm test</command>
123+
</execute_command>
124+
125+
# Result: ✅ Command executes successfully using CLITerminalAdapter
126+
```
127+
128+
### VSCode Context (Still Working)
129+
130+
```
131+
# VSCode user uses extension normally
132+
# execute_command tool continues to work via TerminalRegistry
133+
# Result: ✅ No changes, full backward compatibility
134+
```
135+
136+

## Next Steps
167+
168+
### Ready for Production ✅
169+
170+
The implementation is complete and ready for production use. Users can now:
171+
172+
1. Use `execute_command` tool in CLI context via `roo-cli`
173+
2. Continue using `execute_command` tool in VSCode extension
174+
3. Benefit from unified terminal execution across both contexts
175+
176+
### Future Enhancements (Optional)
177+
178+
1. **Terminal Manager Interface**: Unify terminal architecture across contexts
179+
2. **Enhanced Error Reporting**: CLI-specific error messages and debugging
180+
3. **Performance Optimization**: Optimize adapter overhead if needed
181+
4. **Extended Terminal Features**: Add CLI-specific terminal capabilities
182+
183+
## Conclusion
184+
185+
The `execute_command` tool is now fully functional in CLI context while maintaining complete backward compatibility with VSCode. The implementation uses a clean adapter pattern that bridges the interface differences between CLI and VSCode terminal systems, providing a robust and maintainable solution.
186+
187+
