Tencent released a great paper on self-improving agent harnesses.
If you maintain a production agent harness, finding every file behind one behavior is often harder than writing the edit.
Harness Handbook builds a three-level map from runtime behaviors to source locations using static analysis and LLM-assisted structuring.
Its BGPD workflow guides coding agents from the system overview to relevant stages, functions, and files, then verifies every candidate against current source.
