# Claude Task Executor Integration - GuruRMM Agent
|
||||
|
||||
## Integration Status: [SUCCESS]
|
||||
|
||||
Successfully integrated Claude Code task execution capabilities into the GuruRMM Agent.
|
||||
|
||||
## Date: 2026-01-21
|
||||
|
||||
## Files Modified
|
||||
|
||||
### 1. New Files Added
|
||||
- **src/claude.rs** - Complete Claude task executor module
|
||||
- Working directory validation (restricted to C:\Shares\test)
|
||||
- Task input sanitization (command injection prevention)
|
||||
- Rate limiting (max 10 tasks per hour)
|
||||
- Concurrent execution limiting (max 2 simultaneous tasks)
|
||||
- Comprehensive error handling and logging
|
||||
|
||||
### 2. Modified Files
|
||||
|
||||
#### Cargo.toml
|
||||
- Added `once_cell = "1.19"` dependency for global static initialization
|
||||
- All other required dependencies already present (tokio, serde, serde_json)
|
||||
|
||||
#### src/main.rs
|
||||
- Added `mod claude;` declaration at line 6 (before config module)
|
||||
|
||||
#### src/transport/mod.rs
|
||||
- Added `ClaudeTask` variant to `CommandType` enum:
|
||||
```rust
|
||||
ClaudeTask {
|
||||
task: String,
|
||||
working_directory: Option<String>,
|
||||
context_files: Option<Vec<String>>,
|
||||
}
|
||||
```
|
||||
|
||||
#### src/transport/websocket.rs
|
||||
- Added `use once_cell::sync::Lazy;` import
|
||||
- Added `use crate::claude::{ClaudeExecutor, ClaudeTaskCommand};` import
|
||||
- Added global Claude executor: `static CLAUDE_EXECUTOR: Lazy<ClaudeExecutor>`
|
||||
- Modified `run_command()` function to handle `ClaudeTask` command type
|
||||
- Maps Claude task results to command result format (exit codes, stdout, stderr)
|
||||
|
||||
## Build Results
|
||||
|
||||
### Compilation Status: [SUCCESS]
|
||||
|
||||
```
|
||||
Finished `release` profile [optimized] target(s) in 1m 38s
|
||||
```
|
||||
|
||||
**Binary Size:** 3.5 MB (optimized release build)
|
||||
**Location:** `target/release/gururmm-agent.exe`
|
||||
|
||||
### Warnings: Minor (unrelated to Claude integration)
|
||||
- Unused imports in updater/mod.rs and main.rs (pre-existing)
|
||||
- Unused methods in updater module (pre-existing)
|
||||
- No warnings from Claude integration code
|
||||
|
||||
## Security Features
|
||||
|
||||
### Working Directory Restriction
|
||||
- All Claude tasks restricted to `C:\Shares\test` and subdirectories
|
||||
- Canonical path resolution prevents directory traversal attacks
|
||||
- Validates directory exists before execution
|
||||
|
||||
### Task Input Sanitization
|
||||
- Prevents command injection via forbidden characters: `& | ; ` $ ( ) < > \n \r`
|
||||
- Maximum task length: 10,000 characters (DoS prevention)
|
||||
- Empty task detection
|
||||
|
||||
### Rate Limiting
|
||||
- Maximum 10 tasks per hour per agent
|
||||
- Rate limit window: 3600 seconds (rolling window)
|
||||
- Execution timestamps tracked in memory
|
||||
|
||||
### Concurrent Execution Control
|
||||
- Maximum 2 simultaneous Claude tasks
|
||||
- Active task counter with mutex protection
|
||||
- Prevents resource exhaustion
|
||||
|
||||
### Context File Validation
|
||||
- Verifies files exist before execution
|
||||
- Ensures files are within working directory
|
||||
- Validates file paths contain valid UTF-8
|
||||
|
||||
## Command Protocol
|
||||
|
||||
### Server → Agent Message Format
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "command",
|
||||
"payload": {
|
||||
"id": "550e8400-e29b-41d4-a716-446655440000",
|
||||
"command_type": {
|
||||
"claude_task": {
|
||||
"task": "Check the sync log for errors in last 24 hours",
|
||||
"working_directory": "C:\\Shares\\test\\logs",
|
||||
"context_files": ["sync.log", "error.log"]
|
||||
}
|
||||
},
|
||||
"command": "unused for claude_task",
|
||||
"timeout_seconds": 300,
|
||||
"elevated": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Agent → Server Result Format
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "command_result",
|
||||
"payload": {
|
||||
"command_id": "550e8400-e29b-41d4-a716-446655440000",
|
||||
"exit_code": 0,
|
||||
"stdout": "Claude Code output here...",
|
||||
"stderr": "",
|
||||
"duration_ms": 45230
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Exit Codes
|
||||
- **0** - Task completed successfully
|
||||
- **1** - Task failed (execution error)
|
||||
- **124** - Task timed out
|
||||
- **-1** - Executor error (rate limit, validation failure)
|
||||
|
||||
## Usage Example
|
||||
|
||||
### From GuruRMM Server
|
||||
```python
|
||||
# Send Claude task command via WebSocket
|
||||
command = {
|
||||
"type": "command",
|
||||
"payload": {
|
||||
"id": str(uuid.uuid4()),
|
||||
"command_type": {
|
||||
"claude_task": {
|
||||
"task": "Analyze the sync logs and report any errors from the last 24 hours",
|
||||
"working_directory": "C:\\Shares\\test",
|
||||
"context_files": ["sync.log"]
|
||||
}
|
||||
},
|
||||
"command": "", # Unused for claude_task
|
||||
"timeout_seconds": 600, # 10 minute timeout
|
||||
"elevated": False
|
||||
}
|
||||
}
|
||||
await websocket.send_json(command)
|
||||
```
|
||||
|
||||
### Expected Behavior
|
||||
1. Agent receives command via WebSocket
|
||||
2. Validates working directory and context files
|
||||
3. Checks rate limit (10 tasks/hour)
|
||||
4. Checks concurrent limit (2 simultaneous)
|
||||
5. Spawns Claude Code CLI process
|
||||
6. Captures stdout/stderr asynchronously
|
||||
7. Returns result to server with exit code and output
|
||||
|
||||
## Testing Recommendations
|
||||
|
||||
### 1. Basic Task Execution
|
||||
```json
|
||||
{
|
||||
"claude_task": {
|
||||
"task": "List files in current directory"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Working Directory Validation
|
||||
```json
|
||||
{
|
||||
"claude_task": {
|
||||
"task": "Check directory contents",
|
||||
"working_directory": "C:\\Shares\\test\\subdir"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Context File Usage
|
||||
```json
|
||||
{
|
||||
"claude_task": {
|
||||
"task": "Analyze this log file for errors",
|
||||
"context_files": ["test.log"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Rate Limiting Test
|
||||
- Send 11 tasks within 1 hour
|
||||
- 11th task should fail with rate limit error
|
||||
|
||||
### 5. Concurrent Execution Test
|
||||
- Send 3 tasks simultaneously
|
||||
- First 2 should execute, 3rd should fail with concurrent limit error
|
||||
|
||||
### 6. Security Tests
|
||||
- Attempt directory traversal: `../../../Windows`
|
||||
- Attempt command injection: `task; del *.*`
|
||||
- Attempt path traversal in context files
|
||||
|
||||
## Integration Checklist

|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Memory Usage
|
||||
- Each active Claude task spawns separate process
|
||||
- Stdout/stderr buffered in memory during execution
|
||||
- Rate limiter maintains timestamp vector (max 10 entries)
|
||||
- Minimal overhead from global static executor
|
||||
|
||||
### CPU Usage
|
||||
- Claude Code CLI handles actual task processing
|
||||
- Agent only manages process lifecycle and I/O
|
||||
- Async I/O prevents blocking on output capture
|
||||
|
||||
### Network Impact
|
||||
- Results sent back via existing WebSocket connection
|
||||
- No additional network overhead
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **Windows-Only Claude Code CLI**
|
||||
- Claude Code CLI currently requires Windows
|
||||
- Unix support depends on Claude Code CLI availability
|
||||
|
||||
2. **Fixed Working Directory Base**
|
||||
- Hardcoded to `C:\Shares\test`
|
||||
- Could be made configurable in future updates
|
||||
|
||||
3. **No Progress Reporting**
|
||||
- Long-running tasks don't report progress
|
||||
- Only final result sent to server
|
||||
|
||||
4. **Single Rate Limit Pool**
|
||||
- Rate limit applies per agent, not per user
|
||||
- Could be enhanced with user-specific limits
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
1. **Configurable Security Settings**
|
||||
- Allow admin to configure working directory base
|
||||
- Adjustable rate limits and concurrent task limits
|
||||
|
||||
2. **Progress Streaming**
|
||||
- Stream Claude Code output in real-time
|
||||
- Send periodic progress updates to server
|
||||
|
||||
3. **Task History**
|
||||
- Log completed tasks to database
|
||||
- Provide task execution history API
|
||||
|
||||
4. **User-Specific Limits**
|
||||
- Rate limiting per user, not per agent
|
||||
- Different limits for different user roles
|
||||
|
||||
5. **Output Size Limits**
|
||||
- Prevent excessive memory usage from large outputs
|
||||
- Truncate or stream large results
