openkb-html-critic skillB
openkb-html-critic is agent-read markdown (skill) from yuezhiai/jonex: 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 change.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
