Review KiCad schematic/PCB changes with agent-readable evidence: visual pixel diff between revisions, semantic tree diff, ERC/DRC set-diff vs baseline, and the forum-distilled rule canon. Use before committing any schematic/PCB change, when asked to review a design, or to compare revisions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Design review: triple diff + rule canon
## Triple diff (vs git baseline)
**Implemented:** `cd $(kx root) && python3 -m
kicad_lib.cli diff REV /abs/path/FILE.kicad_sch` → JSON with `semantic`
(symbols added/removed/moved/changed, labels, count deltas), `pixel`
(changed_px + bbox_mm + composite path), `erc_new`/`erc_gone`. Artifacts
land in `~/.cache/kx_scratch/` (never /tmp — flatpak kicad-cli can't see
host /tmp): `diff.png` composite (grey = unchanged, red = removed,
green = added). Crop the bbox_mm region and Read it as evidence.
Python API: `probe()` lives in `kicad_lib.cli` (NOT .source);
`diff.semantic_diff(probe_a, probe_b)` takes its dicts. `kx diff` needs
the FILE inside a git repo (baseline = revision); for two loose files
call `diff.render_png`/`pixel_diff`/`semantic_diff` directly.
Crop formula: px = mm * render_width_px / paper_width_mm (A4=297,
A3=420; render default 2400 px wide).
Gotchas baked into kicad_lib/diff.py — keep them if reimplementing:
- kicad-cli `--no-background-color` SVGs rasterize to TRANSPARENT PNGs;
flatten onto white before grayscale or `convert("L")` maps the whole
background to black and the diff goes blind.

How to install
mdr add avatarsd/kiskill/kicad-review@sha256:b9f0e525ec1ab065The line at the top of this page pins the label git:20260611.db3c74c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
