Vassago PoC

Distributed authentication proof-of-concept built with Spring Boot 4 and WebFlux. Offloads all credential management and JWT cryptographic signing to OpenBao (a HashiCorp Vault fork), keeping the application itself fully stateless and secret-free. Fully containerized with Docker Compose — Postgres, OpenBao, and the app spin up with a single command.

vassago_docs_util

CLI tool that auto-generates README documentation for any codebase using Claude AI. Runs repomix to extract the project's file tree and source, then streams a tailored response from Claude Haiku in three modes: concise overview, verbose per-method docs, or public-facing onboarding guide. Estimates token cost before sending.
