Transform basic chatbot into DeepSpaceSearch agentic research app

Major enhancements:
- Integrate smolagents CodeAgent framework with multi-step reasoning
- Add web search (DuckDuckGo), webpage scraping, and image generation (FLUX.1) tools
- Implement streaming chat interface with configurable agent parameters (max steps, verbosity, temperature, top-p)
- Add comprehensive README with architecture docs, installation guide, usage examples, and MCP integration roadmap
- Include project infrastructure: requirements.txt, .gitignore, LICENSE (Apache 2.0), and CLAUDE.md instructions

This transforms the template into a production-ready deep research application with OAuth support for HF Spaces deployment.

+
+## Project Overview
+
+DeepSpaceSearch is an agentic deep research application built with Gradio and smolagents. It provides a chat interface where an AI agent can perform web searches, generate images, and provide comprehensive answers by executing multi-step reasoning tasks. The application is designed to run on Hugging Face Spaces with OAuth authentication.
+
+## Architecture
+
+This is a single-file Gradio application (`app.py`) built on the **smolagents** framework. Key architectural components:
+
+**Agent System** (`app.py:52-64`):
+- Uses `CodeAgent` from smolagents as the core reasoning engine
+- The agent orchestrates multi-step tasks using available tools
+- Configured with `max_steps` to limit execution depth and `verbosity_level` for logging
+
+**Tool Ecosystem** (`app.py:17-26`):
+- `DuckDuckGoSearchTool`: Web search with rate limiting (5 results, 2.0s rate limit)
+- `FinalAnswerTool`: Required for the agent to return structured final responses
+- `image_generation_tool`: Remote tool loaded from HF Space (black-forest-labs/FLUX.1-schnell) for image generation
+- Tools are imported from smolagents or dynamically loaded using `Tool.from_space()`
+
+**Model Layer** (`app.py:42-49`):
+- Uses `InferenceClientModel` wrapper around Hugging Face Inference API
+- Default model: `Qwen/Qwen2.5-Coder-32B-Instruct` (configurable via `HF_MODEL_ID` env var)
+- Model parameters (max_tokens, temperature, top_p) are user-configurable through the UI
+
+**Streaming Interface** (`app.py:66-71`):
+- `stream_to_gradio()` converts agent execution steps into Gradio-compatible message stream
+- Messages are yielded as they're produced, showing agent reasoning in real-time
+- Uses `gr.ChatInterface` with "messages" type format (role/content dictionaries)
+
+**Authentication**:
+- OAuth flow configured in README.md (`hf_oauth: true`, scope: `inference-api`)
+- Token accessed via `HF_TOKEN` environment variable (automatically set by HF Spaces with OAuth, manually set for local dev)
+
+## Development Commands
+
+ALWAYS USE A VIRTUAL ENVIRONMENT BEFORE RUNNING LOCALLY!!!
+
+**Setup**:
+```bash
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+**Run locally**:
+```bash
+python app.py
+```
+Launches Gradio interface at http://127.0.0.1:7860
+
+**Environment Configuration**:
+Create a `.env` file for local development:
+```
+HF_TOKEN=hf_...  # Your Hugging Face token with inference-api scope
+HF_MODEL_ID=Qwen/Qwen2.5-Coder-32B-Instruct  # Optional: override default model
+```
+
+## Hugging Face Spaces Deployment
+
+The app auto-deploys on HF Spaces via README.md metadata:
+- `sdk: gradio` with `sdk_version: 5.42.0`
+- `app_file: app.py`
+- OAuth is handled automatically by the platform when `hf_oauth: true` is set
+- The `HF_TOKEN` environment variable is automatically populated with the user's OAuth token
+
+## Key Dependencies
+
+- `smolagents[gradio]`: Agentic framework with Gradio streaming support
+- `gradio[oauth]==5.42.0`: UI framework with OAuth support
+- `duckduckgo_search` / `ddgs`: Web search backend
+- `huggingface_hub`: Inference API client
+- `python-dotenv`: Environment variable management for local development
+
+## Adding New Tools
+
+To add a tool to the agent:
+
+**From smolagents built-ins**:
+```python
+from smolagents import YourTool
+your_tool = YourTool()
+agent = CodeAgent(tools=[search_tool, your_tool, final_answer], ...)
+```
+
+**From a Hugging Face Space**:
+```python
+your_tool = Tool.from_space(
+    space_id="namespace/space-name",
+    name="tool_name",
+    description="What this tool does. Returns X.",
+    api_name="/endpoint_name",
+)
+```
+
+Always include `FinalAnswerTool()` in the tools list - it's required for the agent to return results.

-An example chatbot using [Gradio](https://gradio.app), [`huggingface_hub`](https://huggingface.co/docs/huggingface_hub/v0.22.2/en/index), and the [Hugging Face Inference API](https://huggingface.co/docs/api-inference/index).
+# DeepSpaceSearch 🔍
+
+An agentic deep research application powered by [smolagents](https://huggingface.co/docs/smolagents), [Gradio](https://gradio.app), and the [Hugging Face Inference API](https://huggingface.co/docs/api-inference/index). DeepSpaceSearch combines web search, webpage analysis, and image generation capabilities in an intelligent AI agent that can perform multi-step reasoning to answer complex questions.
+
+## Features
+
+- **🤖 Agentic AI**: Built on smolagents' `CodeAgent` framework for autonomous multi-step task execution
+- **🔎 Web Search**: Integrated DuckDuckGo search for real-time information retrieval
+- **🌐 Web Scraping**: Visit and extract content from webpages using `VisitWebpageTool`
+- **🎨 Image Generation**: Generate images using FLUX.1-schnell through Hugging Face Spaces integration
+- **💬 Streaming Chat Interface**: Real-time streaming of agent reasoning steps
+- **⚙️ Configurable Parameters**: Adjust max steps, verbosity, temperature, and token limits
+- **🔐 OAuth Authentication**: Seamless authentication via Hugging Face OAuth
+
+## Architecture
+
+DeepSpaceSearch is built as a single-file Gradio application with the following components:
+
+### Agent System (`app.py:61-75`)
+- **`CodeAgent`**: Core reasoning engine from smolagents
+- Orchestrates multi-step tasks using available tools
+- Configurable execution depth and verbosity
+
+### Tool Ecosystem (`app.py:21-31`)
+- **`DuckDuckGoSearchTool`**: Web search with rate limiting (5 results max, 2.0s rate limit)
+- **`VisitWebpageTool`**: Extract and analyze webpage content
+- **`FinalAnswerTool`**: Required for agent to return structured responses
+- **`image_generation_tool`**: Remote tool from HF Space (black-forest-labs/FLUX.1-schnell)
+
+### Model Layer (`app.py:51-58`)
+- **`InferenceClientModel`**: Wrapper around Hugging Face Inference API
+- Default model: `Qwen/Qwen2.5-Coder-32B-Instruct`
+- User-configurable parameters (max_tokens, temperature, top_p)
+
+### Streaming Interface (`app.py:86-88`)
+- `stream_to_gradio()` converts agent execution steps to Gradio messages
+- Real-time display of agent reasoning process
+- Messages format: `{role: "assistant", content: "..."}`
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.10+
+- Hugging Face account (for inference API access)
+- HF token with `inference-api` scope
+
+### Installation
+
+**ALWAYS USE A VIRTUAL ENVIRONMENT:**
+
+```bash
+# Clone the repository
+git clone https://huggingface.co/spaces/YOUR_USERNAME/DeepSpaceSearch
+cd DeepSpaceSearch
+
+# Create and activate virtual environment
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install dependencies
+pip install -r requirements.txt
+```
+
+### Configuration
+
+#### Authentication (Required)
+
+**Recommended: Use Hugging Face CLI**
+
+The easiest and most secure way to authenticate locally is using the Hugging Face CLI:
+
+```bash
+hf auth login
+```
+
+This will prompt you to paste your HF token (get one at <https://huggingface.co/settings/tokens> with `inference-api` scope) and securely store it in `~/.cache/huggingface/token`.
+
+**Alternative: Use .env file**
+
+If you prefer environment variables, create a `.env` file:
+
+```env
+HF_TOKEN=hf_...  # Your HF token with inference-api scope
+```
+
+#### Optional Environment Variables
+
+You can customize the application behavior with these optional environment variables in your `.env` file:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `HF_MODEL_ID` | `Qwen/Qwen2.5-Coder-32B-Instruct` | Override the default LLM model |
+
+Example `.env` with optional variables:
+
+```env
+# Optional: Use a different model
+HF_MODEL_ID=meta-llama/Llama-3.3-70B-Instruct
+```
+
+### Running Locally
+
+```bash
+python app.py
+```
+
+The application will launch at http://127.0.0.1:7860
+
+## Usage
+
+1. **Login**: Click the login button and authenticate with your Hugging Face account
+2. **Ask a question**: Type your query in the chat interface
+3. **Configure settings** (optional): Click "Additional Inputs" to adjust:
+   - **Max Steps**: Maximum reasoning steps (default: 6)
+   - **Verbosity Level**: Log detail level (default: 1)
+   - **Max New Tokens**: Token generation limit (default: 2096)
+   - **Temperature**: Creativity control (default: 0.5)
+   - **Top-P**: Nucleus sampling threshold (default: 0.95)
+4. **Watch the agent work**: See real-time reasoning steps as the agent searches, analyzes, and formulates answers
+
+### Example Queries
+
+- "What are the latest developments in quantum computing?"
+- "Look up the 10 day forcast for the EST timezone and generate an image."
+- "Compare the top 3, by number of cars sold, electric vehicles in 2025."
+- "What is the current weather in Tokyo and show me an image of the city."
+
+## Deployment
+
+### Hugging Face Spaces
+
+The app auto-deploys on Hugging Face Spaces via the metadata in README.md:
+
+- `sdk: gradio` with `sdk_version: 5.42.0`
+- `app_file: app.py`
+- `hf_oauth: true` enables automatic OAuth authentication
+- `HF_TOKEN` is automatically populated with the user's OAuth token
+
+Simply push to your Space's repository and it will deploy automatically.
+
+## Dependencies
+
+| Package | Purpose |
+|---------|---------|
+| `smolagents[gradio]` | Agentic framework with Gradio streaming |
+| `gradio[oauth]==5.42.0` | UI framework with OAuth support |
+| `duckduckgo_search` / `ddgs` | Web search backend |
+| `huggingface_hub` | Inference API client |
+| `python-dotenv` | Environment variable management |
+
+## Adding New Tools
+
+### From smolagents built-ins:
+
+```python
+from smolagents import YourTool
+your_tool = YourTool()
+agent = CodeAgent(tools=[search_tool, your_tool, final_answer], ...)
+```
+
+### From a Hugging Face Space:
+
+```python
+your_tool = Tool.from_space(
+    space_id="namespace/space-name",
+    name="tool_name",
+    description="What this tool does. Returns X.",
+    api_name="/endpoint_name",
+)
+```
+
+**Important**: Always include `FinalAnswerTool()` in the tools list - it's required for the agent to return results.

+# Security Review Report - DeepSpaceSearch
+
+**Review Date**: 2025-11-23
+**Reviewer**: Automated Security Analysis
+**Scope**: PR changes from basic chatbot to agentic AI application
+**Methodology**: Static code analysis with false positive filtering
+
+---
+
+## Executive Summary
+
+**Result**: No high-confidence security vulnerabilities were identified in this PR.
+
+All potential findings were determined to be false positives after rigorous validation against established security precedents and exclusion criteria. Four potential issues were identified during initial analysis, but each failed to meet the required ≥8/10 confidence threshold for reporting.
+
+---
+
+## Analysis Methodology
+
+This review followed a three-phase approach:
+
+1. **Initial Vulnerability Identification**: Analyzed code changes for common security issues including injection vulnerabilities, authentication bypasses, and code execution risks
+2. **False Positive Filtering**: Applied strict exclusion criteria including:
+   - DoS/resource exhaustion issues (explicitly excluded from scope)
+   - Environment variable attacks (per precedent: environment variables are trusted)
+   - Lack of hardening measures vs. concrete exploitable vulnerabilities
+   - Theoretical vs. practical security risks
+3. **Confidence Scoring**: Assigned confidence scores (1-10) based on exploitability, with threshold of ≥8 required for reporting
+
+---
+
+## Findings Summary
+
+| # | Issue | Initial Severity | Confidence Score | Status |
+|---|-------|------------------|------------------|--------|
+| 1 | Unpinned smolagents dependency (CVE-2025-5120) | HIGH | 6/10 | **Excluded** |
+| 2 | Prompt injection via web browsing | HIGH | 3/10 | **Excluded** |
+| 3 | Unvalidated execution parameters | HIGH | 2/10 | **Excluded** |
+| 4 | Unvalidated HF_MODEL_ID env var | MEDIUM | 2/10 | **Excluded** |
+
+---
+
+## Detailed Analysis
+
+### Finding 1: Unpinned smolagents Dependency
+
+**Initial Assessment**: CodeAgent uses unpinned `smolagents[gradio]` dependency which could install versions vulnerable to CVE-2025-5120 (CVSS 9.9 - Critical sandbox escape RCE).
+
+**Code Location**:
+- `app.py` lines 61-75 (CodeAgent instantiation)
+- `requirements.txt` line 6 (`smolagents[gradio]` without version pin)
+
+**False Positive Analysis**:
+```
+Confidence Score: 6/10 - BELOW THRESHOLD
+
+Reasons for exclusion:
+1. Fresh installations today would receive v1.23.0 (patched version)
+2. CVE-2025-5120 affects versions < 1.17.0 (patched May 2025)
+3. This is a dependency management best practice, not an exploitable vulnerability in the current codebase
+4. Deployment on HF Spaces provides containerized isolation
+5. No evidence of vulnerable version being actively deployed
+
+Classification: Dependency management issue, not active vulnerability
+```
+
+**Recommendation**: While not a reportable vulnerability, consider pinning to `smolagents[gradio]>=1.17.0` as a best practice to prevent regression.
+
+---
+
+### Finding 2: Prompt Injection via Web Browsing
+
+**Initial Assessment**: `VisitWebpageTool` enables fetching arbitrary web content that could contain hidden prompt injection payloads.
+
+**Code Location**: `app.py` lines 22, 66 (VisitWebpageTool usage)
+
+**False Positive Analysis**:
+```
+Confidence Score: 3/10 - BELOW THRESHOLD
+
+Reasons for exclusion:
+1. This is a documented, known limitation of ALL agentic AI systems with web access
+2. Per smolagents official docs: "an agent browsing the web could arrive on a malicious
+   website that contains harmful instructions"
+3. Matches HARD EXCLUSION #14: "Including user-controlled content in AI system prompts
+   is not a vulnerability"
+4. No actionable fix exists without removing core "deep research" functionality
+5. Same limitation exists in: OpenAI GPT with browsing, Claude with MCP, Gemini with
+   extensions, AutoGPT, LangChain agents, etc.
+6. Framework authors acknowledge this as inherent to autonomous agents, not a bug
+
+Classification: Expected behavior of agentic AI systems, not a security boundary violation
+```
+
+**Recommendation**: This is an inherent characteristic of web-browsing AI agents. If concerned, consider:
+- Documenting this limitation in user-facing documentation
+- Implementing domain allowlisting for high-security deployments (at cost of functionality)
+- Using remote code execution sandboxing (E2B/Docker) for defense-in-depth
+
+---
+
+### Finding 3: Unvalidated Execution Parameters
+
+**Initial Assessment**: Users control agent parameters (`max_steps`, `temperature`) without validation, potentially increasing exploitation probability.
+
+**Code Location**: `app.py` lines 34-43, 70, 104-113
+
+**False Positive Analysis**:
+```
+Confidence Score: 2/10 - BELOW THRESHOLD
+
+Reasons for exclusion:
+1. Matches HARD EXCLUSION #1: "Denial of Service vulnerabilities"
+2. Matches HARD EXCLUSION #3: "Rate limiting or resource exhaustion issues"
+3. Matches HARD EXCLUSION #4: "Memory consumption or CPU exhaustion"
+4. Matches HARD EXCLUSION #6: "Lack of hardening measures"
+5. High max_steps → resource consumption (DoS), not code injection
+6. High temperature → output randomness, not exploitable code injection path
+7. No concrete exploit chain beyond resource exhaustion
+
+Classification: Resource exhaustion / missing input validation (hardening issue)
+```
+
+**Recommendation**: While not a security vulnerability, consider implementing reasonable limits for operational stability:
+- Cap `max_steps` to 20-50 (vs unlimited)
+- Restrict `temperature` to 0.0-1.0 (vs 0.0-2.0)
+- Add server-side validation
+
+---
+
+### Finding 4: Unvalidated HF_MODEL_ID Environment Variable
+
+**Initial Assessment**: Model ID loaded from environment variable without validation, allowing potential substitution with malicious models.
+
+**Code Location**: `app.py` lines 18, 55
+
+**False Positive Analysis**:
+```
+Confidence Score: 2/10 - BELOW THRESHOLD
+
+Reasons for exclusion:
+1. DIRECTLY INVALIDATED by Precedent #3: "Environment variables and CLI flags are
+   trusted values. Attackers are generally not able to modify them in a secure
+   environment. Any attack that relies on controlling an environment variable is invalid."
+2. Matches HARD EXCLUSION #6: "Lack of hardening measures"
+3. No concrete attack path without environment variable control
+4. In HF Spaces: env vars controlled by Space owner, not end users
+5. In local dev: if attacker controls env vars, they already have code execution
+
+Classification: Invalid per precedent - environment variables are trusted
+```
+
+**Recommendation**: If defense-in-depth hardening is desired, consider implementing model ID allowlisting, but this is not fixing a vulnerability.
+
+---
+
+## Code Changes Summary
+
+The PR converts a basic Gradio chatbot to an agentic AI application using smolagents:
+
+**Key Changes**:
+- Replaced `InferenceClient` with `CodeAgent` from smolagents
+- Added tools: `DuckDuckGoSearchTool`, `VisitWebpageTool`, `FinalAnswerTool`, image generation
+- Enabled autonomous multi-step reasoning
+- Added configurable parameters: max_steps, verbosity, temperature, top_p
+- Implemented streaming agent responses via `stream_to_gradio()`
+
+**Security Posture**:
+- OAuth authentication via HF Spaces (`hf_oauth: true`)
+- Containerized deployment on HF Spaces
+- Token-based authentication for Inference API
+- Standard smolagents security model with local code execution
+
+---
+
+## Risk Assessment
+
+**Overall Risk Level**: **LOW**
+
+The code changes introduce standard agentic AI capabilities using the smolagents framework. All identified issues fall into one of these categories:
+
+1. **Best practice recommendations** (dependency pinning)
+2. **Inherent limitations of agentic AI** (prompt injection via web content)
+3. **Excluded issue types** (DoS/resource exhaustion)
+4. **Invalid attack vectors** (environment variable control)
+
+No high-confidence, exploitable security vulnerabilities were found that meet the reporting criteria.
+
+---
+
+## Recommendations
+
+### Operational Best Practices (Non-Security)
+1. Pin `smolagents[gradio]>=1.17.0` in requirements.txt for dependency stability
+2. Consider implementing max_steps caps (e.g., ≤50) for operational stability
+3. Document inherent limitations of web-browsing agents in user-facing docs
+
+### Optional Defense-in-Depth (If Desired)
+4. Implement remote code execution sandboxing (E2B/Docker) per smolagents security guide
+5. Add domain allowlisting for `VisitWebpageTool` in high-security deployments
+6. Create model ID allowlist if model selection is sensitive
+
+**Note**: None of the above recommendations address exploitable vulnerabilities. They are hardening measures and operational improvements.
+
+---
+
+## Conclusion
+
+This PR does not introduce any high-confidence security vulnerabilities that meet the established reporting criteria. The conversion from a basic chatbot to an agentic AI application follows standard patterns in the smolagents framework and inherits the security characteristics (and limitations) of autonomous AI agents generally.
+
+The application is suitable for deployment on Hugging Face Spaces with standard OAuth authentication. Users should be aware of the inherent limitations of web-browsing AI agents, as documented by the smolagents framework.
