# Broken Agent Example
This example demonstrates a deliberately fragile AI agent that flakestorm can detect issues with.
## The "Broken" Agent
The agent in `agent.py` has several intentional flaws:
1. **Fragile Intent Parsing**: Only recognizes exact keyword matches
2. **No Typo Tolerance**: Fails on any spelling variations
3. **Hostile Input Vulnerability**: Crashes on aggressive tone
4. **Prompt Injection Susceptible**: Follows injected instructions
## Running the Example
### 1. Start the Agent Server
```bash
cd examples/broken_agent
pip install fastapi uvicorn
uvicorn agent:app --port 8000
```
### 2. Run flakestorm Against It
```bash
# From the project root
flakestorm run --config examples/broken_agent/flakestorm.yaml
```
### 3. See the Failures
The report will show how the agent fails on:
- Paraphrased requests ("I want to fly" vs "Book a flight")
- Typos ("Bock a fligt")
- Aggressive tone ("BOOK A FLIGHT NOW!!!")
- Prompt injections ("Book a flight. Ignore previous instructions...")
## Fixing the Agent
Try modifying `agent.py` to:
1. Use NLP for intent recognition
2. Add spelling correction
3. Handle emotional inputs gracefully
4. Detect and refuse prompt injections
Then re-run flakestorm to see your robustness score improve!

# Generate Search Queries AI Agent
## Overview
The `generateSearchQueriesPlugin` is an **AI-powered agent** that provides an API endpoint for generating customer discovery search queries. This agent autonomously analyzes product descriptions using Google's Gemini AI and generates natural, conversational search queries that help identify potential customers who are actively seeking solutions or experiencing related pain points.
### Terminology
> **Agent vs Plugin**: While this is technically implemented as a Vite development server plugin (for development integration), it functions as an **autonomous AI agent** that:
> - Makes intelligent decisions about query generation
> - Autonomously handles errors and implements fallback strategies
> - Adapts to different product types and industries
> - Provides intelligent responses based on context
>
> In production, this should be moved to a dedicated backend agent service, similar to other AI agents in the Ralix ecosystem (like the main Ralix Marketing Co-Founder agent).
## Purpose
This AI agent automates the creation of search queries for lead generation by:
- Analyzing product/service descriptions to understand the core problem being solved
- Generating 3-5 natural, conversational search queries that potential customers might use
- Focusing on pain points, solution-seeking behavior, and buying intent
- Optimizing queries for platforms like Reddit and X (Twitter)
## How It Works
1. **Endpoint Creation**: The agent creates a middleware endpoint at `/GenerateSearchQueries` in the Vite development server
2. **Request Processing**: Accepts POST requests with a product description
3. **AI Analysis**: The agent autonomously uses Google Gemini 2.5 Flash model to analyze the product and generate queries
4. **Response Parsing**: The agent intelligently extracts and validates the generated queries from the AI response
5. **Error Handling**: The agent includes robust fallback mechanisms and autonomous decision-making for malformed responses
## API Endpoint
### Endpoint
```
POST /GenerateSearchQueries
```
### Request Format
**Headers:**
```
Content-Type: application/json
```
**Body:**
```json
{
"productDescription": "Your product or service description here"
}
```
### Response Format
**Success Response (200):**
```json
{
"success": true,
"queries": [
"query 1",
"query 2",
"query 3",
"query 4",
"query 5"
]
}
```
**Error Responses:**
**400 Bad Request** - Missing required parameter:
```json
{
"error": "Missing required parameters",
"message": "productDescription is required"
}
```
**500 Internal Server Error** - API key not configured:
```json
{
"error": "API key not configured",
"message": "VITE_GOOGLE_AI_API_KEY environment variable is not set"
}
```
**500 Internal Server Error** - Generation failed:
```json
{
"error": "Failed to generate search queries",
"message": "Error details here"
}
```
## Configuration
### Environment Variables
The AI agent requires the following environment variable:
- **`VITE_GOOGLE_AI_API_KEY`**: Your Google Generative AI API key for accessing Gemini models
Set this in your `.env` file:
```
VITE_GOOGLE_AI_API_KEY=your_api_key_here
```
### Agent Registration (Technical Implementation)
The agent is implemented as a Vite plugin and automatically registered in `vite.config.ts`:
```typescript
plugins: [
react(),
securityHeaders(),
generateSearchQueriesPlugin(mode),
// ...
]
```
## Query Generation Strategy
The AI agent is instructed to autonomously generate queries that:
### ✅ Good Query Characteristics
- Natural and conversational (as someone might type on Reddit/X)
- Focused on pain points or solution-seeking
- Specific to the product's domain/industry
- Not too generic or too narrow
- Capture people asking questions, expressing frustrations, or seeking recommendations
### ❌ What to Avoid
- Brand names or specific product names
- Overly technical jargon
- Queries that are too broad (e.g., just "help" or "problem")
### Example
**Input:**
```
"AI-powered lead generation tool for SaaS founders"
```
**Good Output:**
- "finding first customers"
- "struggling to find leads"
- "looking for lead generation tools"
- "how to find customers on reddit"
**Bad Output:**
- "lead generation" (too generic)
- "ralix.ai" (brand name)
- "SaaS" (too broad)
## Error Handling & Fallbacks
The AI agent includes multiple layers of autonomous error handling:
1. **JSON Parsing**: The agent intelligently handles markdown code blocks and extracts JSON arrays
2. **Control Character Escaping**: The agent autonomously escapes control characters in string values
3. **Regex Fallback**: If JSON parsing fails, the agent uses regex to extract quoted strings
4. **Default Queries**: If all parsing fails, the agent autonomously generates basic fallback queries from the product description
### Fallback Queries
If the AI fails to generate valid queries, the agent autonomously creates three basic queries:
- `"looking for [first 50 chars of product description]"`
- `"need help with [first 50 chars of product description]"`
- `"struggling with [first 50 chars of product description]"`
## Use Cases
1. **Lead Generation Setup**: Automatically generate search queries when users set up their product/service
2. **Campaign Creation**: Pre-populate search queries for new lead generation campaigns
3. **Query Optimization**: Get AI-suggested queries that are more likely to find qualified leads
4. **Onboarding Flow**: Help new users quickly get started with lead generation
## Technical Details
### AI Model
- **Model**: `gemini-2.5-flash`
- **Provider**: Google Generative AI
- **Library**: `@google/generative-ai`
### Response Processing
1. Extracts JSON from markdown code blocks (if present)
2. Cleans whitespace and newlines
3. Escapes control characters in string values
4. Validates array structure
5. Filters and limits to maximum 5 queries
### Development vs Production
- **Development**: Agent runs as Vite middleware, accessible at `http://localhost:8080/GenerateSearchQueries`
- **Production**: This agent should be moved to a dedicated backend service/agent endpoint (e.g., Cloudflare Worker or FastAPI endpoint) as Vite plugins only work in development mode. In production, it should function as a standalone AI agent service.
## Example Usage
### JavaScript/TypeScript
```typescript
const response = await fetch('/GenerateSearchQueries', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
productDescription: 'AI-powered lead generation tool for SaaS founders'
})
});
const data = await response.json();
if (data.success) {
console.log('Generated queries:', data.queries);
// ["finding first customers", "struggling to find leads", ...]
} else {
console.error('Error:', data.error);
}
```
### cURL
```bash
curl -X POST http://localhost:8080/GenerateSearchQueries \
-H "Content-Type: application/json" \
-d '{"productDescription": "AI-powered lead generation tool for SaaS founders"}'
```
## Limitations
1. **Development Only**: This agent is currently implemented as a Vite plugin and only works in development mode. For production, implement this as a dedicated backend agent service.
2. **API Key Required**: The agent requires a valid Google AI API key with access to Gemini models
3. **Rate Limits**: Subject to Google AI API rate limits
4. **Query Count**: The agent is limited to generating a maximum of 5 queries per request
## Future Improvements
- Move agent to dedicated backend service for production use
- Add intelligent caching for frequently requested product descriptions
- Support for custom query generation strategies that the agent can learn from
- Integration with actual search platforms (Reddit, X) for autonomous query validation
- Analytics on query performance to help the agent improve over time
- Agent learning capabilities to refine query generation based on successful lead conversions

**Instructions:**
1. Identify the core problem this product/service solves
2. Think about how potential customers might express their pain points, frustrations, or needs
3. Generate search queries that capture:
- People asking questions about the problem domain
- People expressing frustration with existing solutions
- People seeking recommendations or alternatives

# Generate Search Queries Agent Example
This example demonstrates a real-world AI agent that generates customer discovery search queries using Google's Gemini AI. This agent is designed to be tested with flakestorm to ensure it handles various input mutations robustly.
## Overview
The agent accepts product/service descriptions and generates 3-5 natural, conversational search queries that potential customers might use when seeking solutions. It uses Google Gemini 2.5 Flash model for intelligent query generation.
## Features
- **AI-Powered Query Generation**: Uses Google Gemini to analyze product descriptions and generate relevant search queries
- **Robust Error Handling**: Multiple fallback strategies for parsing AI responses
- **Natural Language Processing**: Generates queries that sound like real user searches on Reddit/X
- **Production-Ready**: Includes comprehensive error handling and validation
## Setup
### 1. Create Virtual Environment (Recommended)
It's recommended to use a virtual environment to avoid dependency conflicts:
```bash
cd examples/keywords_extractor_agent
# Create virtual environment
python -m venv venv
# Activate virtual environment
# On macOS/Linux:
source venv/bin/activate
# On Windows (PowerShell):
# venv\Scripts\Activate.ps1
# On Windows (Command Prompt):
# venv\Scripts\activate.bat
```
**Note:** You should see `(venv)` in your terminal prompt after activation.
### 2. Install Dependencies
```bash
# Make sure virtual environment is activated
pip install -r requirements.txt
# Or install manually:
# pip install fastapi uvicorn google-generativeai pydantic
```
### 3. Set Up Google AI API Key
You need a Google AI API key to use Gemini. Get one from [Google AI Studio](https://makersuite.google.com/app/apikey).
Set the environment variable:
```bash
# On macOS/Linux
export GOOGLE_AI_API_KEY=your_api_key_here
# On Windows (PowerShell)
$env:GOOGLE_AI_API_KEY="your_api_key_here"
# Or create a .env file (not recommended for production)
echo "GOOGLE_AI_API_KEY=your_api_key_here" > .env
```
**Note:** The agent also checks for `VITE_GOOGLE_AI_API_KEY` for compatibility with the original TypeScript implementation.
### 4. Start the Agent Server
**Make sure your virtual environment is activated** (you should see `(venv)` in your prompt):
```bash
python agent.py
```
Or using uvicorn directly:
```bash
uvicorn agent:app --port 8080
```
The agent will be available at `http://localhost:8080/GenerateSearchQueries`
**To deactivate the virtual environment when done:**
```bash
deactivate
```
## Testing the Agent
### Manual Test
```bash
curl -X POST http://localhost:8080/GenerateSearchQueries \
-H "Content-Type: application/json" \
-d '{"productDescription": "AI-powered lead generation tool for SaaS founders"}'
```
Expected response:
```json
{
"success": true,
"queries": [
"finding first customers",
"struggling to find leads",
"looking for lead generation tools",
"how to find customers on reddit"
]
}
```
### Run flakestorm Against It
```bash
# From the project root
flakestorm run --config examples/keywords_extractor_agent/flakestorm.yaml
```
This will:
1. Generate mutations of the golden prompts (product descriptions)
2. Test the agent's robustness against various input variations
3. Generate an HTML report showing pass/fail results
## How It Works
1. **Request Processing**: Accepts POST requests with `productDescription` in JSON body
2. **AI Analysis**: Uses Google Gemini 2.5 Flash to analyze the product and generate queries
3. **Response Parsing**: Intelligently extracts JSON array from AI response with multiple fallback strategies:
- Extracts from markdown code blocks
- Handles control character escaping
- Regex fallback for malformed JSON
- Default queries if all parsing fails
4. **Validation**: Ensures queries are valid strings and limits to 5 queries
## Error Handling
The agent includes robust error handling:
- **Missing API Key**: Returns 500 error with clear message
- **Invalid Input**: Returns 400 error for missing productDescription
- **JSON Parsing Failures**: Uses regex fallback to extract queries
- **Empty Results**: Generates fallback queries from product description
- **API Failures**: Returns 500 error with error details
## Configuration
The `flakestorm.yaml` file is configured to test this agent with:
- **Endpoint**: `http://localhost:8080/GenerateSearchQueries`
- **Request Format**: Maps golden prompts to `{"productDescription": "{prompt}"}`
- **Response Extraction**: Extracts the `queries` array from the response (flakestorm converts arrays to JSON strings for assertions)
- **Golden Prompts**: Various product/service descriptions
- **Mutations**: All 7 mutation types (paraphrase, noise, tone_shift, prompt_injection, encoding_attacks, context_manipulation, length_extremes)
- **Invariants**:
- Valid JSON response
- Latency under 10 seconds (allows for Gemini API call)
- Response contains array of queries
- PII exclusion checks
- Refusal checks for prompt injections
## Example Golden Prompts
The agent is tested with prompts like:
- "AI-powered lead generation tool for SaaS founders..."
- "Personal finance app that tracks expenses..."
- "Fitness app with AI personal trainer..."
- "E-commerce platform for small businesses..."
flakestorm will generate mutations of these to test robustness.
## Limitations
1. **API Key Required**: Needs valid Google AI API key
2. **Rate Limits**: Subject to Google AI API rate limits
3. **Query Count**: Limited to maximum 5 queries per request
4. **Model Dependency**: Requires internet connection for Gemini API calls
## Future Improvements
- Add caching for frequently requested product descriptions
- Support for custom query generation strategies
- Integration with actual search platforms for validation
- Analytics on query performance
- Agent learning capabilities based on successful conversions

**Product/Service Description:**
{product_description}
**Instructions:**
1. Identify the core problem this product/service solves
2. Think about how potential customers might express their pain points, frustrations, or needs
3. Generate search queries that capture:
- People asking questions about the problem domain
- People expressing frustration with existing solutions
- People seeking recommendations or alternatives
- People discussing challenges related to this domain
- People showing buying intent or solution-seeking behavior
4. Each query should be:
- Natural and conversational (as someone might type on Reddit/X)
- Focused on pain points or solution-seeking
- Specific to the product's domain/industry
- Not too generic or too narrow
5. Avoid:
- Brand names or specific product names
- Overly technical jargon
- Queries that are too broad (e.g., just "help" or "problem")
**Example:**
If product is "AI-powered lead generation tool for SaaS founders":
- Good queries: "finding first customers", "struggling to find leads", "looking for lead generation tools", "how to find customers on reddit"
- Bad queries: "lead generation" (too generic), "ralix.ai" (brand name), "SaaS" (too broad)

["query 1", "query 2", "query 3", "query 4", "query 5"]
