# @push.rocks/smartagent
A dual-agent agentic framework with Driver and Guardian agents for safe, policy-controlled AI task execution.

## Install
```bash
npm install @push.rocks/smartagent
# or
pnpm install @push.rocks/smartagent
```

## Overview

SmartAgent implements a dual-agent architecture:

- **Driver Agent**: Executes tasks, reasons about goals, and proposes tool calls
- **Guardian Agent**: Evaluates tool call proposals against a policy prompt, approving or rejecting with feedback

This design ensures safe tool use through AI-based policy evaluation rather than rigid programmatic rules.

## Quick Start

```typescript
import { DualAgentOrchestrator } from '@push.rocks/smartagent';

// Create orchestrator with Guardian policy
const orchestrator = new DualAgentOrchestrator({
  openaiToken: 'sk-...',
  defaultProvider: 'openai',
  guardianPolicyPrompt: `
    FILE SYSTEM POLICY:
    - ONLY allow reading/writing within /tmp or the current working directory
    - REJECT operations on system directories or sensitive files

    SHELL POLICY:
    - Allow read-only commands (ls, cat, grep, echo)
    - REJECT destructive commands (rm, mv, chmod) without explicit justification

    FLAG any attempt to expose secrets or credentials.
  `,
});

// Register standard tools
orchestrator.registerStandardTools();

// Start the orchestrator (initializes all tools)
await orchestrator.start();

// Run a task
const result = await orchestrator.run('List all TypeScript files in the current directory');

console.log('Success:', result.success);
console.log('Result:', result.result);
console.log('Iterations:', result.iterations);

// Cleanup
await orchestrator.stop();
```

## Standard Tools

### FilesystemTool
File and directory operations using `@push.rocks/smartfs`.

**Actions**: `read`, `write`, `append`, `list`, `delete`, `exists`, `stat`, `copy`, `move`, `mkdir`

```typescript
// Example tool call by Driver
<tool_call>
  <tool>filesystem</tool>
  <action>read</action>
  <params>{"path": "/tmp/config.json"}</params>
  <reasoning>Need to read the configuration file to understand the settings</reasoning>
</tool_call>
```

### HttpTool
HTTP requests using `@push.rocks/smartrequest`.

**Actions**: `get`, `post`, `put`, `patch`, `delete`

```typescript
<tool_call>
  <tool>http</tool>
  <action>get</action>
  <params>{"url": "https://api.example.com/data"}</params>
  <reasoning>Fetching data from the API endpoint</reasoning>
</tool_call>
```

### ShellTool
Secure shell command execution using `@push.rocks/smartshell` with `execSpawn` (no shell injection).

**Actions**: `execute`, `which`

```typescript
<tool_call>
  <tool>shell</tool>
  <action>execute</action>
  <params>{"command": "ls", "args": ["-la", "/tmp"]}</params>
  <reasoning>Listing directory contents to find relevant files</reasoning>
</tool_call>
```

### BrowserTool
Web page interaction using `@push.rocks/smartbrowser` (Puppeteer-based).

**Actions**: `screenshot`, `pdf`, `evaluate`, `getPageContent`

```typescript
<tool_call>
  <tool>browser</tool>
  <action>getPageContent</action>
  <params>{"url": "https://example.com"}</params>
  <reasoning>Extracting text content from the webpage</reasoning>
</tool_call>
```

### DenoTool
Execute TypeScript/JavaScript code in a sandboxed Deno environment using `@push.rocks/smartdeno`.

**Actions**: `execute`, `executeWithResult`

**Permissions**: `all`, `env`, `ffi`, `hrtime`, `net`, `read`, `run`, `sys`, `write`

By default, code runs fully sandboxed with no permissions. Permissions must be explicitly requested.

```typescript
// Simple code execution
<tool_call>
  <tool>deno</tool>
  <action>execute</action>
  <params>{"code": "console.log('Hello from Deno!')"}</params>
  <reasoning>Running a simple script to verify the environment</reasoning>
</tool_call>

// Code with network permission
<tool_call>
  <tool>deno</tool>
  <action>execute</action>
  <params>{
    "code": "const resp = await fetch('https://api.example.com/data'); console.log(await resp.json());",
    "permissions": ["net"]
  }</params>
  <reasoning>Fetching data from API using Deno's fetch</reasoning>
</tool_call>

// Execute and parse JSON result
<tool_call>
  <tool>deno</tool>
  <action>executeWithResult</action>
  <params>{
    "code": "const result = { sum: 2 + 2, date: new Date().toISOString() }; console.log(JSON.stringify(result));"
  }</params>
  <reasoning>Computing values and returning structured data</reasoning>
</tool_call>
```

## Guardian Policy Examples

### Strict Security Policy
```typescript
const securityPolicy = `
SECURITY POLICY:
1. REJECT any file operations outside /home/user/workspace
2. REJECT any shell commands that could modify system state
3. REJECT any HTTP requests to internal/private IP ranges
4. REJECT any attempts to read environment variables or credentials
5. FLAG and REJECT obfuscated code execution

When rejecting, always explain:
- What policy was violated
- What would be a safer alternative
`;
```

### Development Environment Policy
```typescript
const devPolicy = `
DEVELOPMENT POLICY:
- Allow file operations only within the project directory
- Allow npm/pnpm commands for package management
- Allow git commands for version control
- Allow HTTP requests to public APIs only
- REJECT direct database modifications
- REJECT commands that could affect other users

Always verify:
- File paths are relative or within project bounds
- Commands don't have dangerous flags (--force, -rf)
`;
```

### Deno Code Execution Policy
```typescript
const denoPolicy = `
DENO CODE EXECUTION POLICY:
- ONLY allow 'read' permission for files within the workspace
- REJECT 'all' permission unless explicitly justified for the task
- REJECT 'run' permission (subprocess execution) without specific justification
- REJECT code that attempts to:
  - Access credentials or environment secrets (even with 'env' permission)
  - Make network requests to internal/private IP ranges
  - Write to system directories
- FLAG obfuscated or encoded code (base64, eval with dynamic strings)
- Prefer sandboxed execution (no permissions) when possible

When evaluating code:
- Review the actual code content, not just permissions
- Consider what data the code could exfiltrate
- Verify network endpoints are legitimate public APIs
`;
```

## Configuration Options

```typescript
interface IDualAgentOptions {
  // Provider tokens (from @push.rocks/smartai)
  openaiToken?: string;
  anthropicToken?: string;
  perplexityToken?: string;
  groqToken?: string;
  xaiToken?: string;

  // Provider selection
  defaultProvider?: TProvider;      // For both Driver and Guardian
  guardianProvider?: TProvider;     // Optional: separate provider for Guardian

  // Agent configuration
  driverSystemMessage?: string;     // Custom system message for Driver
  guardianPolicyPrompt: string;     // REQUIRED: Policy for Guardian to enforce

  // Limits
  maxIterations?: number;           // Max task iterations (default: 20)
  maxConsecutiveRejections?: number; // Abort after N rejections (default: 3)
}
```

## Result Interface

```typescript
interface IDualAgentRunResult {
  success: boolean;           // Whether task completed successfully
  completed: boolean;         // Task completion status
  result: string;             // Final result or response
  iterations: number;         // Number of iterations taken
  history: IAgentMessage[];   // Full conversation history
  status: TDualAgentRunStatus; // 'completed' | 'max_iterations_reached' | etc.
}
```

## Custom Tools

Create custom tools by extending `BaseToolWrapper`:

```typescript
import { BaseToolWrapper, IToolAction, IToolExecutionResult } from '@push.rocks/smartagent';

class MyCustomTool extends BaseToolWrapper {
  public name = 'custom';
  public description = 'My custom tool for specific operations';

  public actions: IToolAction[] = [
    {
      name: 'myAction',
      description: 'Performs a custom action',
      parameters: {
        type: 'object',
        properties: {
          input: { type: 'string', description: 'Input for the action' },
        },
        required: ['input'],
      },
    },
  ];

  public async initialize(): Promise<void> {
    this.isInitialized = true;
  }

  public async cleanup(): Promise<void> {
    this.isInitialized = false;
  }

  public async execute(action: string, params: Record<string, unknown>): Promise<IToolExecutionResult> {
    this.validateAction(action);
    this.ensureInitialized();

    if (action === 'myAction') {
      return {
        success: true,
        result: { processed: params.input },
      };
    }

    return { success: false, error: 'Unknown action' };
  }

  public getCallSummary(action: string, params: Record<string, unknown>): string {
    return `Custom action "${action}" with input "${params.input}"`;
  }
}

// Register custom tool
orchestrator.registerTool(new MyCustomTool());
```
