Open Source
OSS / Technical Samples
We open-source the implementation patterns from our production stack that can be generalized
independently of client work. New sample implementations land every Monday.

Production-ready patterns for getting structured JSON from Claude API - Tool Use, auto-retry, partial recovery, streaming, and complex nested schemas. Battle-tested in real pipelines.
Automated Publishing Pipeline
Every Monday at 9:00 JST, our in-house AI pipeline picks a fresh technical topic, generates the implementation, tests, CI configuration, and bilingual JP/EN README as a set, then auto-publishes to GitHub. Every repo is gated by a green GitHub Actions CI — code quality is enforced mechanically.
