| name | tool-comparison-heatmap |
| description | Create interactive feature-comparison heatmaps that score, rank, and crown winners across multiple tools, repos, or products. Use this skill whenever the user asks to compare tools, software, GitHub repos, frameworks, extensions, or any set of alternatives across multiple features or criteria โ especially when they want a visual matrix, heatmap, scorecard, ranking, or 'who wins' analysis. Also trigger when the user says things like 'compare features', 'which is the best', 'feature matrix', 'score them 1-100', 'rank these tools', 'Vergleich', 'Heatmap', 'wer gewinnt', or 'Gewinner kรผren'. The output is always an interactive React (.jsx) artifact with clickable GitHub/repo links, last-update dates, color-coded scores, sorting, and an automatic winner badge. |
Tool Comparison Heatmap Skill
Create a polished, interactive React heatmap that compares tools/repos across user-defined features, scores each 0โ100, links to repositories, shows last-update dates, and automatically crowns the winner(s).
When to Use
- User wants to compare multiple tools, repos, frameworks, extensions, or products
- User asks for a feature matrix, heatmap, scorecard, or ranking
- User wants to know "which is the best" across several criteria
- User mentions "Gewinner kรผren", "wer gewinnt", "score them", "rank", "compare features"
Research Phase
Before building the heatmap, gather accurate data:
- Identify the tools the user wants to compare (aim for 5โ30)
- Define feature categories โ ask the user or derive from context. Typical categories:
- Technical capabilities (e.g., multi-tab, parallel agents, self-healing)
- Ecosystem (e.g., BYOK, open source, MCP support, Chrome extension)
- Usability (e.g., no-code, voice, memory/persistence)
- Trust (e.g., privacy, license, community size)
- Research each tool using web search:
- GitHub URL (exact, verified)
- GitHub stars (current count)
- Last meaningful update date (check releases page or recent commits)
- Feature support level per category
- Score each feature 0โ100 based on research:
- 85โ100: Excellent / native support / best-in-class
- 65โ84: Good / solid support with minor gaps
- 45โ64: Partial / workaround needed / experimental
- 25โ44: Weak / very limited
- 0โ24: Missing / not applicable
Output Requirements
Generate a single .jsx React artifact with ALL of the following:
1. Data Structure
const tools = [
{
name: "Tool Name",
github: "https://github.com/org/repo",
stars: "~12.6k",
lastUpdate: "Apr 2026",
type: "Chrome Extension / Framework / etc.",
feature1: 85,
feature2: 40,
notes: {
feature1: "Detailed explanation of why this score...",
},
},
];
const features = [
{ key: "feature1", label: "Display Name", desc: "Tooltip description" },
];
2. Interactive Table
- Sticky first column with tool name, type, stars, and last-update date
- Tool name is a clickable link โ opens the GitHub repo in a new tab (
target="_blank")
- Last update shown as subtle text below the name (e.g., "Letztes Update: Apr 2026")
- Stars shown as
โญ ~12.6k
- Color-coded score cells: green (85+), teal (65-84), amber (45-64), red (0-44)
- Sortable columns: click any header to sort ascending/descending
- Click any cell โ shows detail panel below with the note/explanation
3. Winner Badge
- Calculate average score (
total) across all features for each tool
- Display a ๐ trophy column or winner row at the top
- The tool with the highest average gets a visible
๐ Gewinner badge
- If user asked for category winners, also show per-feature winners
4. Styling
- Use CSS variables for theming (works in light/dark mode)
- Font: import a distinctive Google Font (e.g., DM Sans, Plus Jakarta Sans)
- Monospace font for scores (e.g., JetBrains Mono)
- Alternating row backgrounds for readability
- Responsive horizontal scroll for many columns
- Frosted/blurred detail panel on cell click
5. Winner Summary Box
Below the table, add a colored summary box:
๐ Gesamtsieger: [Tool Name] mit ร [Score]/100
- List top 3 tools with their average scores
- Per-category leaders:
Bester bei [Feature]: [Tool] ([Score])
- If the user's question had a specific focus (e.g.,
wer kann parallele Tab-Gruppen), highlight that category winner prominently
Template Code Structure
import { useState } from "react";
export default function ToolComparisonHeatmap() {
const [sortKey, setSortKey] = useState("total");
const [sortDir, setSortDir] = useState(-1);
const [selected, setSelected] = useState(null);
}
Critical Rules
- Every GitHub link must be verified โ search the web to confirm the URL exists. Never guess.
- Last update date must be researched โ check the repo's releases or commit history.
- Stars must be current โ use web search to find the latest count.
- Tool names must be clickable links โ use
<a href={tool.github} target="_blank" rel="noopener noreferrer">.
- Winner must be automatically calculated โ not hardcoded.
- The artifact must be a single
.jsx file โ no separate CSS files.
- All text in the user's language โ if user speaks German, labels/descriptions in German.
