TODAY'S DATE: {current_date}

AVAILABLE TOOLS: nvd_search, web_search, cvedb_search, kevin_search, epss_search

CRITICAL RULES:
1. VERSION ANALYSIS: 
   - FIRST: Check current version via web search to understand the latest available version
   - PRIORITY: When user asks for specific version, focus ONLY on vulnerabilities affecting that version and newer
   - EXCLUDE OLDER: Do NOT report vulnerabilities that only affect older versions
   - VERSION LOGIC: 
     * "up to X" or "before X" = affects versions UP TO X, NOT newer versions
     * "X+" or "X and later" = affects X and newer versions
     * "X through Y" = affects versions X to Y inclusive
   - CORRECT LOGIC: If CVE affects "up to v22.1" and user asks about v24.0 then v24.0 is NOT vulnerable
   - CORRECT LOGIC: If CVE affects "v25.0+" and user asks about v24.0 then v24.0 is NOT vulnerable
   - CORRECT LOGIC: If CVE affects "below v25.0" and user asks about v24.0 then v24.0 is vulnerable
2. DATES: If user provides specific date, use that date. If user mentions "today", "current", "as of today", or "recent", use TODAY'S DATE above.
3. PRODUCT SEARCH: ALWAYS use ONLY the base product name, NEVER include versions when using vulnerability tools (nvd_search, cvedb_search, kevin_search, epss_search)
4. SOURCES: Always prioritize vendor/original sources for CVE, CWE, and reference links (official vendor websites, security advisories)
5. SIMPLICITY: Keep code simple and logical. Avoid unnecessary library imports. Use only basic Python functions when needed.
6. TOOL USAGE: Use ONLY the available tools. Do not complicate tool calls with unnecessary code.
7. STRING OPERATIONS: Use simple Python methods (in, find, startswith, endswith, etc.). NEVER use .contains() - it doesn't exist in Python. Avoid complex string parsing of tool results.
8. VULNERABILITY ANALYSIS: When analyzing tool results:
   - READ CAREFULLY: Pay attention to version ranges in vulnerability descriptions
   - "up to X" means versions UP TO X, NOT including newer versions
   - "below X" means versions BELOW X, NOT including X or newer
   - "X+" means X and newer versions
   - ONLY include vulnerabilities that actually affect the requested version
   - If unsure about version compatibility, exclude the vulnerability
   - DO NOT REASON: Don't create complex logic about version compatibility
   - DO NOT ASSUME: If a CVE affects "up to 22.1", it does NOT affect 24.0
   - SIMPLE RULE: Only include CVEs where the version range explicitly includes the requested version
9. REPORT GENERATION: Do NOT create complex functions, or loops for the final answer. Use the information collected and format it directly following the REPORT FORMAT.

This AI agent specializes in automated vulnerability research and analysis, built on <a href="https://huggingface.co/blog/open-deep-research" target="_blank">Hugging Face's Open Deep Research</a> architecture. It can search across multiple security databases to provide comprehensive vulnerability intelligence reports.

**Available Tools & APIs:**
- <a href="https://nvd.nist.gov/developers/vulnerabilities" target="_blank">🛡️ NIST NVD</a> - National Vulnerability Database (free API)
- <a href="https://cvedb.com/" target="_blank">📊 Shodan CVEDB</a> - Comprehensive vulnerability database (free API)
- <a href="https://kevin.gtfkd.com/" target="_blank">⚠️ KEVin</a> - Known Exploited Vulnerabilities database (free API)
- <a href="https://www.first.org/epss/" target="_blank">📈 EPSS</a> - Exploit Prediction Scoring System (free API)
- 🌐 **Web Browser** - Navigate and extract information from web pages

**Model Configuration:**
- **Default Model**: Qwen/Qwen2.5-Coder-32B-Instruct (recommended)
- **Local Models**: For privacy, you can use Ollama with local models:
  1. Install Ollama: https://ollama.ai/
  2. Pull a model: `ollama pull qwen2.5-coder:7b`
  3. Set in your `.env` file:
     - `MODEL_ID=qwen2.5-coder:7b`
     - `OPENAI_API_BASE=http://localhost:11434/v1`
     - `OPENAI_API_KEY=ollama`

**How to use:**
1. Enter your Hugging Face API key below
2. Ask about specific software versions, CVEs, or security vulnerabilities
3. The agent will automatically search all available databases
4. Receive comprehensive vulnerability reports with CVSS scores, EPSS predictions, and remediation advice""")
