When the user wants to add, optimize, or audit social share buttons (share article to X, LinkedIn, Facebook, etc.). Also use when the user mentions "share buttons," "social share," "share to X," "share to LinkedIn," "social sharing," "share icons," "share widget," "native share," "Web Share API," or "share intent URLs." For link previews, use open-graph.

Guides implementation of share buttons that let users share the current page (article, post, product) to social platforms. Distinct from social profile links (footer links to your brand's X, LinkedIn, etc.) — share buttons share *this* content.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Fewer, better-placed buttons outperform scattered placement. Research: removing 80% of buttons and repositioning the remaining 20% at high-emotion moments can 3× conversion on share actions.
| Placement | Best For | Notes |
|-----------|----------|-------|
| After first paragraph | Most articles | Catches speed-readers; visible early |
| Sticky sidebar | Long-form (desktop) | Always visible; consider hiding on mobile |
| Below title / hero | Short posts | High visibility |
| End of article | All | Natural completion point; pair with CTA |
| Mid-article (after key insight) | Long content | Place at friction points (after surprising stat, before CTA) |
Avoid: Dozens of icons; every platform when audience uses 2–3. Choose 3–5 platforms that match your audience (e.g. B2B: X, LinkedIn; B2C: X, Facebook, WhatsApp).
Use platform share/intent URLs so users share with one click:
| Platform | Share URL pattern |
|----------|-------------------|
| X (Twitter) | https://twitter.com/intent/tweet?url={url}&text={text} |
| LinkedIn | https://www.linkedin.com/sharing/share-offsite/?url={url} |
| Facebook | https://www.facebook.com/sharer/sharer.php?u={url} |
| WhatsApp | https://wa.me/?text={url}%20{text} |
| Telegram | https://t.me/share/url?url={url}&text={text} |
Encode url and text with encodeURIComponent(). Use page title or a short pre-written message for text — platform-specific prompts with pre-written messages perform ~4× better than generic icons.
Use official brand assets. Minimum sizes and color rules:
| Platform | Min size | Colors | Notes |
|----------|----------|--------|-------|
| Facebook | 16px | Blue #1877F2 or monochrome | No rotation, animation without permission |
| X (Twitter) | 32px | Black or white only | Use current X logo, not deprecated bird |
| LinkedIn | 21px height | Blue #0A66C2 or monochrome | Use "in" bug for icons |
| Instagram | 29×29px | Black, white, or official gradient | Glyph for social icons |
Source icons from official brand resource centers. Outdated or non-compliant icons reduce perceived shareability.
| Item | Guideline |
|------|-----------|
| Format | SVG preferred (scalable, small); PNG/WebP with fallback |
| Performance | Lightweight; avoid heavy share plugins that slow LCP |
| Accessibility | aria-label="Share on X"; keyboard accessible |
| Mobile | Touch targets ≥44×44px; consider native share API (navigator.share) on mobile |
On supported browsers, navigator.share lets users share via system dialog (includes more apps). Fallback to intent links when unsupported:
if (navigator.share) {
navigator.share({ title, url, text }).catch(() => {});
} else {
window.open(shareUrl, '_blank', 'noopener');
}
Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
