Analyzes project structure, module dependencies, imports, and entry points to generate architecture diagrams in Mermaid format
Analyzes ETL and data pipeline code for optimization opportunities across Python (Pandas, PySpark), Rust (polars, datafusion), SQL, and general pipeline descriptions
Validates environment variable configurations and config files (YAML, TOML, JSON, .env) for missing required variables, type mismatches, deprecated keys, naming convention violations, secret exposure risks, and invalid value ranges
Analyzes code for performance bottlenecks including N+1 queries, O(n^2) or worse algorithms, unnecessary allocations, sync I/O in async contexts, excessive cloning, missing caching opportunities, and large payload transfers. Supports Rust, Python, TypeScript, and Go.
Analyzes, improves, and restructures LLM prompts for clarity, efficiency, and reliability
Analyzes source code for common security vulnerabilities including SQL injection, XSS, command injection, hardcoded secrets, insecure deserialization, path traversal, and SSRF

# Log Analysis Report
## Critical Issues
### Connection Pool Exhaustion (3 occurrences)
- **Severity:** ERROR
- **Timeline:** 10:23:01 → 10:23:04 → 10:23:06 (5-second window)
- **Pattern:** Recurring every ~3 seconds — suggests sustained load exceeding pool capacity
- **Root Cause Candidates:**
1. Connection pool too small (max=20) for concurrent request volume
2. Connections not released promptly after query completion
3. Long-running queries holding connections (see: query timeout at 10:23:02)
- **Recommendation:** Increase `max_connections` to 50 and add `connection_timeout_ms: 5000`
## Warnings
| Time | Component | Message | Frequency |
|------|-----------|---------|-----------|
| 10:23:02 | db_query | query timed out after 30s | 1 |
| 10:23:10 | db_migrate | migration 0042_reindex_orders took 45s | 1 |
## Anomaly Detection
✅ **Cluster detected:** 3× connection_pool_exhausted errors within 5s (p<0.01)
⚠️ **Correlation:** connection_pool_exhausted → db_query timeout → all errors are database-related
✅ **No security-relevant patterns detected**
