Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. 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. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "jo4", "name": "Modern URL shortening with QR codes and detailed analytics", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/anandrathnas/jo4", "canonicalUrl": "https://clawhub.ai/anandrathnas/jo4", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/jo4", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=jo4", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "jo4", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-05T17:32:15.964Z", "expiresAt": "2026-05-12T17:32:15.964Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=jo4", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=jo4", "contentDisposition": "attachment; filename=\"jo4-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "jo4" }, "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/jo4" }, "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/jo4", "downloadUrl": "https://openagent3.xyz/downloads/jo4", "agentUrl": "https://openagent3.xyz/skills/jo4/agent", "manifestUrl": "https://openagent3.xyz/skills/jo4/agent.json", "briefUrl": "https://openagent3.xyz/skills/jo4/agent.md" } } ``` ## Documentation ### Jo4 - URL Shortener & Analytics API Jo4 is a modern URL shortening service with QR code generation and detailed link analytics. ### Authentication All protected endpoints require an API key.
