coleam00/Archon — Open-source AI coding harness builder (TypeScript, MIT, 15.9k stars)

Archon is billed as the first open-source harness builder for AI coding, aiming to make AI-assisted coding deterministic and repeatable. It gained 756 stars today (April 11, 2026), totalling 15,930 stars. Built in TypeScript, MIT licensed, last pushed April 11, 2026. With 62 open issues and active maintenance, it presents a potential complement to ODS's ADLC pipeline — specifically around structuring agent prompts and outputs for repeatable coding tasks. Not a direct dependency, but the harness pattern is relevant to ADLC dev agent orchestration.
