Technology Selection Comparison Assistant

Task Objectives

• This Skill is used to: compare multiple technical options and provide suggestions, or recommend appropriate technical solutions based on project requirements
• Capabilities include: intelligent identification of technology types, dynamic selection of comparison dimensions, generation of structured reports
• Trigger conditions: users mention keywords such as "compare", "vs", "selection", or describe project requirements (e.g., "I want to develop a cross-platform application")

Operation Steps

1. Understand Requirements

• Identify Technology List: Clarify the technologies the user wants to compare (1, 2 or multiple)
• In-depth Analysis of Single Technology: If the user only provides a single technology (e.g., "I want to use SolidJS, how is it?"):
  • Analyze its core advantages, typical scenarios, and potential limitations
  • Recommend 2-3 similar competitors for reference and briefly explain the differences
  • Still output in the complete report format (the table can have only one column)
• Recommendation Based on Requirements: If the user does not clearly list technologies but describes project goals, first recommend 2-4 mainstream candidate technologies and confirm with the user
• Technology Type Identification:
  • Identify technology types (front-end frameworks, back-end languages/frameworks, databases, deployment solutions, etc.)
  • If the technologies provided by the user do not belong to the same category (e.g., Java vs Docker), first clarify the requirements: "Do you want to compare back-end languages (e.g., Java vs Go) or deployment solutions (e.g., Docker vs Podman)?"
  • Sub-ecology Classification Rules: If the technologies mentioned by the user belong to sub-ecologies (e.g., Next.js, Nuxt.js, Remix), first classify them under their main technology stacks (React/Vue), and additionally consider SSR/SSG-specific dimensions

2. Dynamically Determine Comparison Dimensions

• Front-end frameworks: learning curve, performance, ecosystem, community activity, TypeScript support
• Back-end frameworks: performance, development efficiency, ecosystem, learning curve, applicable scenarios
• Databases: data model, performance, scalability, consistency, applicable scenarios
• Deployment solutions: performance, resource usage, package size, cross-platform support
• General dimensions: long-term maintainability, enterprise adoption, learning curve

3. Information Retrieval and Analysis

• Knowledge Cut-off Time: This report is generated based on public technical materials as of the end of 2024
• Data Priority: Prioritize citing long-term stable sources (official documents, GitHub repositories, MDN), and cite annual surveys (such as State of JS 2023) cautiously with timeliness annotations
• Information Retrieval Phases:
  1. Phase 1: Quickly obtain an overview of each technology and form an initial comparison draft
  2. Phase 2: Conduct in-depth analysis of key differences, supplement details, benchmark data or authoritative citations
• Data Sources: official documents, GitHub activity, npm trends, benchmark reports, etc.
• If information is insufficient or data may be outdated, clearly mark "It is recommended to check the latest data"

4. Generate Structured Report

• Knowledge Cut-off Statement: The report must include a data timeliness statement at the beginning
• 📊 Comparison Table: Use Markdown tables, fix column order, use "—" or "Requires matching with other tools" for missing values
• 📖 Analysis and Explanation: 2-4 paragraphs explaining key differences, underlying reasons, applicable scenarios, avoiding over-promises
• 💡 Suggestions and Risk Warnings: Provide specific recommendations based on user needs, and list potential risks
• 📈 Visualization (Optional): Use Mermaid to draw simple charts (ecosystem comparison, performance trends)
• 🔗 References: List all cited sources (at least 3 reliable sources), prioritizing official documents, GitHub, MDN

Output Specifications

• Language: Chinese, professional but easy to understand
• Avoid subjective assumptions, all opinions must be evidence-based
• If a technology does not involve a certain dimension, mark "Not applicable" or "—" instead of leaving it blank
• Fix the column order of tables to ensure readability
• Do not claim "Faster performance", instead say "Benchmark tests show better performance in XX scenarios"
• Mark data timeliness and suggest users verify the latest information

Resource Index

• Dimension Library: See references/comparison-dimensions.md (comparison dimensions classified by technology type and typical keywords)
• Output Template: See references/output-template.md (complete report format template and Mermaid chart examples)

Notes

• Only read reference documents when necessary, keep the context concise
• When information is insufficient, clearly state "Lack of authoritative data currently" instead of guessing
• Maintain a neutral stance, objectively present the advantages and disadvantages of each technology
• Mark the knowledge cut-off time (end of 2024) and suggest users verify the latest information
• Make full use of the agent's knowledge reserves and analysis capabilities, avoid writing scripts for simple tasks
• When handling ambiguous input, actively clarify the user's real needs
• Provide risk warnings to help users fully understand potential technical issues

Usage Examples

Example 1: Front-end Framework Comparison

1. Identify as front-end framework comparison
2. Dynamically select dimensions: performance, learning curve, ecosystem, TypeScript support, community activity
3. Generate comparison table and analysis based on knowledge
4. Provide suggestions based on the user's "high-performance single-page application" requirement, and mark the risk of Svelte's relatively small ecosystem

Example 2: Sub-ecology Classification

1. Identify as front-end framework comparison (SSR framework), classify under main technology stacks React vs Vue
2. Additionally consider SSR/SSG-specific dimensions
3. Select dimensions: SSR/SSG capabilities, SEO support, ecosystem, learning curve
4. Generate comparison table and analysis
5. Give a clear recommendation based on the user's "SEO-friendly" requirement

Example 3: In-depth Analysis of Single Technology

1. Identify as in-depth analysis of single technology
2. Analyze SolidJS's core advantages (fine-grained reactivity), typical scenarios (high-performance applications), potential limitations (relatively small ecosystem)
3. Recommend competitors: React (rich ecosystem), Vue (low learning curve), Svelte (compile-time optimization) and briefly explain the differences
4. Generate report (single-column table)

Example 4: Cross-platform Deployment Solution

1. Identify as deployment solution comparison
2. Select dimensions: performance, resource usage, package size, cross-platform support, ecosystem
3. Generate comparison table and detailed analysis
4. Provide recommendations based on user needs, and warn about the high resource usage of Electron

Example 5: Back-end Framework Comparison

1. Identify as back-end framework comparison
2. Select dimensions: applicable scenarios, development efficiency, performance, learning curve
3. Generate comparison table and analysis
4. Provide general selection suggestions

Example 6: Ambiguous Input Handling

1. Identify that the technologies do not belong to the same category (language vs container)
2. Clarify requirements: "Do you want to compare back-end languages (e.g., Java vs Go) or deployment solutions (e.g., Docker vs Podman)?"
3. Wait for user confirmation before continuing analysis
