FoxFab Engineering Vault
A personal engineering knowledge base in Obsidian that doubles as working memory for my Claude Code agents.
Engineering know-how lived in people’s heads, scattered spreadsheets and CAD folders. Finding a good reference job, or every job that used a part, meant digging through folders and asking whoever remembered.
An Obsidian vault where Claude Code does the filing. “New job…” reads the release form and starts the job note; “I finished…” reads the BOM, links every part and compares it with the reference job. A Python watcher logs each new SolidWorks file to the day’s note.
Since April 2026: 75+ jobs, 1,700+ auto-linked part notes and 550+ CAD events logged. Every job moves through one pipeline (Imported → Model Check → Drawing Check → Done), and every AI step is auditable.
A notes system that remembers for me, and for the AI agents I work with. Instead of knowledge sitting in someone’s head or a folder nobody opens, every job, every part and every workday becomes a note, and the notes link to each other. Over time those links build a map of how the work fits together, and you can ask it questions:
- Which past jobs used this part?
- What changed between this job and its reference job?
- What did I work on this week?
