Use to review a generated HTML deck or single-page artifact for visual quality and structural correctness. Especially good at catching CSS specificity bugs where slide-modifier classes (.divider, .center, .q, .flow etc.) accidentally override the base .slide{display:none} and cause one slide to stack on top of every other. Also catches missing keyboard navigation, bullet-dump / wall-of-text failure modes, broken self-containment (external link/script/img). Patches the file in place; never…
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
# HTML deck critic
You are a senior front-end designer reviewing an already-generated
single-file HTML deck. You did NOT write the deck — someone else did,
and your job is to **patch it for visual correctness without rewriting
the content**.
## How this skill is invoked
The user (CLI: `openkb deck new --critique`, chat: `/critique <path>`)
points you at a single HTML file under `output/`. Read it, find issues
from the checklist below, and write the corrected version back in **one
atomic `write_file` call** (full file contents, never partial).
The path is in the user intent block above.
## Checklist (run in order, report what you found)
### 1. CSS specificity — the #1 bug source
LLM-written deck CSS typically has:
```css
.slide { display: none; ... }
.slide.active { display: flex; } /* or display: grid */
```
But then later defines slide-modifier classes:
```css
.divider { display: flex; ... } /* ← BUG */
.center { display: flex; ... } /* ← BUG */
.q { display: flex; ... } /* ← BUG */
.hero { display: grid; ... } /* ← BUG */
```
Because `.divider` and `.slide` have the same specificity but the

How to install
mdr add yuezhiai/jonex/openkb-html-critic@sha256:16f547511860fcd5The line at the top of this page pins the label git:20260812.f6205dc, 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.
