Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "zeroex-swap", "name": "ZeroEx Swap", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/aviclaw/zeroex-swap", "canonicalUrl": "https://clawhub.ai/aviclaw/zeroex-swap", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/zeroex-swap", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=zeroex-swap", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md", "package.json", "quote.js", "swap.js" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "zeroex-swap", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-11T12:20:34.525Z", "expiresAt": "2026-05-18T12:20:34.525Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=zeroex-swap", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=zeroex-swap", "contentDisposition": "attachment; filename=\"zeroex-swap-1.0.1.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "zeroex-swap" }, "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/zeroex-swap" }, "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/zeroex-swap", "downloadUrl": "https://openagent3.xyz/downloads/zeroex-swap", "agentUrl": "https://openagent3.xyz/skills/zeroex-swap/agent", "manifestUrl": "https://openagent3.xyz/skills/zeroex-swap/agent.json", "briefUrl": "https://openagent3.xyz/skills/zeroex-swap/agent.md" } } ``` ## Documentation ### ZeroEx Swap Skill ⚠️ SECURITY WARNING: This skill involves real funds.
