# Send Nestjs Best Practices 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": "agent-nestjs-skills", "name": "Nestjs Best Practices", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/TuanViDev/agent-nestjs-skills", "canonicalUrl": "https://clawhub.ai/TuanViDev/agent-nestjs-skills", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/agent-nestjs-skills", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=agent-nestjs-skills", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T16:55:25.780Z", "expiresAt": "2026-05-07T16:55:25.780Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=network", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=network", "contentDisposition": "attachment; filename=\"network-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null }, "scope": "source", "summary": "Source download looks usable.", "detail": "Yavira can redirect you to the upstream package for this source.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/agent-nestjs-skills" }, "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/agent-nestjs-skills", "downloadUrl": "https://openagent3.xyz/downloads/agent-nestjs-skills", "agentUrl": "https://openagent3.xyz/skills/agent-nestjs-skills/agent", "manifestUrl": "https://openagent3.xyz/skills/agent-nestjs-skills/agent.json", "briefUrl": "https://openagent3.xyz/skills/agent-nestjs-skills/agent.md" } } ``` ## Documentation ### NestJS Best Practices Comprehensive best practices guide for NestJS applications. Contains 40 rules across 10 categories, prioritized by impact to guide automated refactoring and code generation. ### When to Apply Reference these guidelines when: Writing new NestJS modules, controllers, or services Implementing authentication and authorization Reviewing code for architecture and security issues Refactoring existing NestJS codebases Optimizing performance or database queries Building microservices architectures ### Rule Categories by Priority PriorityCategoryImpactPrefix1ArchitectureCRITICALarch-2Dependency InjectionCRITICALdi-3Error HandlingHIGHerror-4SecurityHIGHsecurity-5PerformanceHIGHperf-6TestingMEDIUM-HIGHtest-7Database & ORMMEDIUM-HIGHdb-8API DesignMEDIUMapi-9MicroservicesMEDIUMmicro-10DevOps & DeploymentLOW-MEDIUMdevops- ### 1.
