Agni

Agni checks schematics and boards for design mistakes, such as an I2C bus with no pull-up, a power rail with no decoupling, a USB connector with no ESD protection, or a track narrower than the board's own rules. It reads KiCad, EDIF, IPC-2581, xschem, and gEDA designs into one neutral intermediate representation, and every finding names the net or part it fired on and locates it on the schematic.

Beyond checks, it diffs revisions structurally over the intermediate representation, traces a signal between two pins, walks a review checklist and scores a design against it, and joins a design against extracted datasheet limits to check, for example, that a rail stays inside a part's recommended operating range.

It runs as a CLI and as a browser viewer: agni open serves one board and agni serve opens a tree of them, rendering the design, running checks, and locating each finding on the canvas. The engine also compiles to WebAssembly, so the public demo opens a dropped KiCad or EDIF design, checks it, queries it, and saves a report without uploading the design anywhere.
