# Send Tech Stack Evaluator to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "tech-stack-evaluator", "name": "Tech Stack Evaluator", "source": "tencent", "type": "skill", "category": "效率提升", "sourceUrl": "https://clawhub.ai/alirezarezvani/tech-stack-evaluator", "canonicalUrl": "https://clawhub.ai/alirezarezvani/tech-stack-evaluator", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/tech-stack-evaluator", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=tech-stack-evaluator", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "assets/expected_output_comparison.json", "assets/sample_input_structured.json", "assets/sample_input_tco.json", "assets/sample_input_text.json", "references/examples.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "tech-stack-evaluator", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-01T09:53:16.107Z", "expiresAt": "2026-05-08T09:53:16.107Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=tech-stack-evaluator", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=tech-stack-evaluator", "contentDisposition": "attachment; filename=\"tech-stack-evaluator-2.1.1.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "tech-stack-evaluator" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/tech-stack-evaluator" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/tech-stack-evaluator", "downloadUrl": "https://openagent3.xyz/downloads/tech-stack-evaluator", "agentUrl": "https://openagent3.xyz/skills/tech-stack-evaluator/agent", "manifestUrl": "https://openagent3.xyz/skills/tech-stack-evaluator/agent.json", "briefUrl": "https://openagent3.xyz/skills/tech-stack-evaluator/agent.md" } } ``` ## Documentation ### Technology Stack Evaluator Evaluate and compare technologies, frameworks, and cloud providers with data-driven analysis and actionable recommendations. ### Table of Contents Capabilities Quick Start Input Formats Analysis Types Scripts References ### Capabilities CapabilityDescriptionTechnology ComparisonCompare frameworks and libraries with weighted scoringTCO AnalysisCalculate 5-year total cost including hidden costsEcosystem HealthAssess GitHub metrics, npm adoption, community strengthSecurity AssessmentEvaluate vulnerabilities and compliance readinessMigration AnalysisEstimate effort, risks, and timeline for migrationsCloud ComparisonCompare AWS, Azure, GCP for specific workloads ### Compare Two Technologies Compare React vs Vue for a SaaS dashboard. Priorities: developer productivity (40%), ecosystem (30%), performance (30%). ### Calculate TCO Calculate 5-year TCO for Next.js on Vercel. Team: 8 developers. Hosting: $2500/month. Growth: 40%/year. ### Assess Migration Evaluate migrating from Angular.js to React. Codebase: 50,000 lines, 200 components. Team: 6 developers. ### Input Formats The evaluator accepts three input formats: Text - Natural language queries Compare PostgreSQL vs MongoDB for our e-commerce platform.
