The developer of the coldstart note-capturing tool discovered significant bugs through early user feedback, revealing hidden assumptions in the system's design. A request for a manual capture command exposed flaws in how the system flagged already-processed files, leading to a redesign of the capture model to prioritize actual work over simple appearance in prompts. Additionally, the tool's recall feature, which surfaces relevant older notes, was found to have a baseline precision of only 31%, with issues stemming from common vocabulary matches, repeated injections of the same note, and leakage from telemetry data. After implementing fixes, precision increased to 47%. The developer also addressed issues where notes were present but not searchable due to schema drift across different parts of the system, leading to a unified note schema and the development of a 'kb repair' tool to identify and fix incomplete or unretrievable notes.
