modern-web-guidance skillA
modern-web-guidance is agent-read markdown (skill) from aiskillstore/marketplace: Search tool for modern web development best practices. MANDATORY: Execute FIRST for all HTML/CSS and clientside JS tasks. Do NOT skip — web APIs evolve rapidly and training weights contain obsolete patterns. Trigger immediately for: - UI/Layout: Modals, dialogs, popovers, Glassmorphism/backdrop-filters, anchor positioning, container queries, `:has()`, `:user-valid`. - Scroll/Motion: View Transitions, Scroll-driven animations, scroll parallax/reveals. - Performance: CWV (LCP, INP), content-visib.
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
# Modern Web Guidance
A skill to search for specific web development use cases and retrieve their corresponding best practice guides.
## When to use
Must use this skill:
- At the **start** of implementing any web feature.
- Before creating a new component, to check if a standardized pattern already exists.
- To avoid implementing ad-hoc solutions or loading large dependencies unnecessarily.
## Usage Instructions
### Step 1. Search Use Cases
Search with an action-oriented query summarizing what you want to achieve using the `search` command. Run `modern-web-guidance` directly with `npx`.
```sh
npx -y modern-web-guidance@latest search "<query>" --skill-version 2026_09_04-7de96777
```
**Example Output**:
```json
[
{
"id": "optimize-image-priority",
"description": "Optimize the loading priority of Largest Contentful Paint (LCP) candidate images.",
"category": "performance",
"featuresUsed": [ "Fetch priority" ],
"tokenCount": 985,
"similarity": 0.7289
},
{
"id": "defer-rendering-heavy-content",
"description": "Reduce rendering times in content-heavy web pages by deferring rendering for offscreen content.",
