# Engineering notes.

How we design, build, and run software — the decisions, the trade-offs, and what we’d do differently.

- [Prompts are code. So we built a linter for them.](https://hypermetron.com/blog/prompts-are-code-so-we-built-rubrkit) (2026-09-29): Teams review every pull request, then ship the prompts that drive their AI features with no review at all. Rubrkit is our answer to that gap.
- [Running an eve agent on Slack Socket Mode instead of webhooks](https://hypermetron.com/blog/eve-slack-socket-mode) (2026-09-17): We built a support assistant on eve, Vercel’s open-source agent framework, and connected it to Slack over Socket Mode instead of eve’s built-in Slack connector. Here’s why, and what the wiring looks like.
- [One system for the whole visit: why we built HyperCRM](https://hypermetron.com/blog/hypercrm-one-system-for-the-whole-visit) (2026-09-09): Most clinic software stops at the appointment. HyperCRM carries the visit through: booking, records, clinical notes, files and the invoice.
- [Ingredo: reading labels against your own body, with sources](https://hypermetron.com/blog/ingredo-reading-labels-with-sources) (2026-08-22): A barcode scan should tell you whether a product works for you, not for an average shopper. And it should show where that verdict came from.
- [Taking comment resolution sheets off the spreadsheet](https://hypermetron.com/blog/contrat-comment-resolution-without-spreadsheets) (2026-08-04): Engineering reviews still run on an Excel CRS and a long email thread. Contrat puts documents, comments, revisions and approvals in one workspace.
- [HyperSync: copying Shopify stores without making a mess](https://hypermetron.com/blog/hypersync-copying-shopify-stores-safely) (2026-07-17): Moving data between Shopify stores sounds simple until you run it twice. How HyperSync copies, exports and imports store data safely, and what it deliberately leaves alone.
