Streaming privacy for LLM apps: pii-leak-benchmark (does your gateway leak PII in streams?), chunk-invariance (one-line test for split-boundary leaks), mcp-ssrf-check, and a self-hosted redacting gateway.
Uncompromising test isolation: your tests structurally cannot touch your real files, secrets, or git identity -- First-class support for Go, Python with pytest, and TypeScript with Node
