Quick Start

1. Add Files to Project

Copy these files to your GuruRMM agent project:

agent/
├── src/
│   ├── claude.rs              [NEW] - Claude task executor
│   ├── commands.rs            [MODIFY] - Add claude_task handler
│   └── main.rs                [EXISTING]
├── Cargo.toml                 [MODIFY] - Add dependencies
└── tests/
    └── claude_integration.rs  [OPTIONAL] - Integration tests

2. Update Cargo.toml

Add these dependencies to agent/Cargo.toml:

[dependencies]
tokio = { version = "1.35", features = ["full"] }
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"
once_cell = "1.19"

See Cargo_dependencies.toml for complete dependency list.

3. Modify commands.rs

Add these lines to agent/src/commands.rs:

// At the top with other modules
mod claude;
use crate::claude::{ClaudeExecutor, ClaudeTaskCommand};
use once_cell::sync::Lazy;

// Global executor
static CLAUDE_EXECUTOR: Lazy<ClaudeExecutor> = Lazy::new(|| ClaudeExecutor::new());

// In your command dispatcher
match command_type {
    "shell" => execute_shell_command(&command).await,
    "claude_task" => execute_claude_task(&command).await, // NEW
    _ => Err(format!("[ERROR] Unknown command type: {}", command_type)),
}

// Add this function
async fn execute_claude_task(command: &serde_json::Value) -> Result<String, String> {
    let task_cmd: ClaudeTaskCommand = serde_json::from_value(command.clone())
        .map_err(|e| format!("[ERROR] Failed to parse Claude task command: {}", e))?;
    let result = CLAUDE_EXECUTOR.execute_task(task_cmd).await?;
    serde_json::to_string(&result)
        .map_err(|e| format!("[ERROR] Failed to serialize result: {}", e))
}

See commands_modifications.rs for detailed integration instructions.

4. Build & Deploy

# Build release binary
cargo build --release

# Deploy to AD2
Copy-Item "target\release\gururmm-agent.exe" -Destination "\\AD2\C$\Program Files\GuruRMM\gururmm-agent.exe"

# Restart service on AD2
Restart-Service -Name "gururmm-agent"

See TESTING_AND_DEPLOYMENT.md for complete deployment guide.

Security Features

1. Working Directory Validation

[OK] *Restricted to C:\Shares\test* - Prevents access to system files [OK] Path traversal prevention - Blocks .. and symlink attacks [OK] Existence verification - Directory must exist before execution

2. Input Sanitization

[OK] Command injection prevention - Blocks shell metacharacters [OK] Length limits - Maximum 10,000 characters per task [OK] Dangerous pattern detection - Blocks: & | ; $ ( ) < > \ \n \r`

3. Rate Limiting

[OK] 10 tasks per hour maximum - Prevents abuse and resource exhaustion [OK] Sliding window algorithm - Resets automatically after 1 hour

4. Concurrent Execution Control

[OK] Maximum 2 simultaneous tasks - Preserves CPU and memory [OK] Queue management - Additional tasks rejected with clear error

5. Timeout Protection

[OK] Default 5 minute timeout - Prevents hung processes [OK] Configurable per task - Up to 10 minutes maximum [OK] Graceful termination - Kills process on timeout

---

Configuration

Modifying Security Limits

Edit agent/src/claude.rs constants:

const DEFAULT_WORKING_DIR: &str = r"C:\Shares\test";
const DEFAULT_TIMEOUT_SECS: u64 = 300;  // 5 minutes
const MAX_CONCURRENT_TASKS: usize = 2;
const RATE_LIMIT_WINDOW_SECS: u64 = 3600;  // 1 hour
const MAX_TASKS_PER_WINDOW: usize = 10;

After modifying, rebuild and redeploy:

cargo build --release
# Deploy and restart service

Claude Code CLI Path

If Claude is not in system PATH, modify execute_task_internal():

let mut cli_cmd = Command::new(r"C:\Program Files\Claude\claude.exe");

---

Testing

Unit Tests

cargo test

Tests included:

• Input sanitization validation
• Command injection prevention
• Rate limiter logic
• Path traversal prevention

Integration Tests

See TESTING_AND_DEPLOYMENT.md for 7 comprehensive integration tests:

1. Simple task execution
2. Task with context files
3. Invalid working directory (security)
4. Command injection attempt (security)
5. Timeout handling
6. Rate limiting enforcement
7. Concurrent execution limit

Load Testing

# Test rate limiting (11 tasks rapidly)
for i in {1..11}; do
  curl -X POST "http://172.16.3.30:3001/api/agents/{AD2_AGENT_ID}/command" \
    -H "Content-Type: application/json" \
    -d "{\"command_type\":\"claude_task\",\"task\":\"Test $i\"}"
done

---

Troubleshooting

Issue: "command not found: claude"

Solution:

1. Verify Claude Code is installed: claude --version
2. Add to system PATH if needed
3. Restart agent service after PATH changes

Issue: "Working directory validation failed"

Solution:

1. Verify directory exists: Test-Path "C:\Shares\test\scripts"
2. Check permissions on directory
3. Ensure path is within C:\Shares\test\

Issue: "Rate limit exceeded"

Solution:

• Wait 1 hour for rate limit to reset
• Or restart agent service to reset counter (emergency only)

Issue: Service won't start after deployment

Solution:

1. Check event logs: Get-EventLog -LogName Application -Source "gururmm-agent"
2. Verify binary architecture (x64)
3. Check dependencies: dumpbin /dependents gururmm-agent.exe
4. Rollback to previous version

See TESTING_AND_DEPLOYMENT.md for complete troubleshooting guide.

Performance

Benchmarks (Typical)

Operation	Duration	Notes
Simple task	5-10 sec	"List files", "Echo test"
Log analysis (1 MB file)	15-30 sec	Single file context
Multi-file analysis (5 files)	30-60 sec	Multiple context files
Deep reasoning task	60-180 sec	Complex analysis with reasoning

Resource Usage

Per Task:

• CPU: 10-30% (depends on Claude reasoning)
• Memory: 50-150 MB per Claude process
• Disk I/O: Minimal (only reads context files)

Agent Overhead:

• Idle: <5 MB RAM, <1% CPU
• Active (2 concurrent tasks): ~300 MB RAM, ~50% CPU
