Run the principles check in wireframe, pass or signoff mode: the mechanical half by script, the judgement half by the web-principles agent, findings into the observation store, blocking until each is fixed or waived; proposes amendments to the principles for approval.

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

# The principles check

Load `web-conventions` first. The principles and their mechanical or judgement split: `~/.claude/skills/web-conventions/principles.md`. Scripts: `~/.claude/library/scripts/web/check.py` and `observations.py`.

## Step 1: Mode and inputs

The first word of `$ARGUMENTS` is the mode; the rest are paths. Find what is not given from the task's directories (`docs/scope/`, `docs/artefacts/<slug>/`, `docs/assets/walkthrough/`) and say what was used.

| Mode | Needs | Mechanical subcommands |
|---|---|---|
| `wireframe` | the wireframe page(s), the scope document, the product's CSS | `tokens`, `brief` |
| `pass` | the export file, the source directory, the UI library's CSS, `git diff --name-only` for the pass | `export`, `classes` |
| `signoff` | all of the above plus the captures directory, the route list and the device list | `export --max-age 24`, `classes`, `coverage`, `brief` |

The UI library's CSS is under `node_modules/<package>/` for the library named in the inventory; pass the directory.

## Step 2: Mechanical half

How to install

The exact contents, by fingerprint
mdr add jasonwarrenuk/goblin-mode/Web: Check@sha256:f1febff004e7f568

The line at the top of this page pins the label git:20261015.c0152a5, 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.
