# Send sev-attestation 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. 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": "sev-attestation", "name": "sev-attestation", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/xinyuwang/sev-attestation", "canonicalUrl": "https://clawhub.ai/xinyuwang/sev-attestation", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/sev-attestation", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=sev-attestation", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md", "references/error-codes.md", "references/manual-verification.md", "references/report-fields.md", "scripts/detect-sev-snp.sh" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "sev-attestation", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-05T04:32:08.429Z", "expiresAt": "2026-05-12T04:32:08.429Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=sev-attestation", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=sev-attestation", "contentDisposition": "attachment; filename=\"sev-attestation-1.0.2.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "sev-attestation" }, "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/sev-attestation" }, "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/sev-attestation", "downloadUrl": "https://openagent3.xyz/downloads/sev-attestation", "agentUrl": "https://openagent3.xyz/skills/sev-attestation/agent", "manifestUrl": "https://openagent3.xyz/skills/sev-attestation/agent.json", "briefUrl": "https://openagent3.xyz/skills/sev-attestation/agent.md" } } ``` ## Documentation ### sev-attestation AMD SEV-SNP remote attestation for cryptographic VM identity verification. ### Description Perform AMD SEV-SNP (Secure Encrypted Virtualization - Secure Nested Paging) remote attestation to cryptographically verify VM identity and integrity. Use this skill when: Proving a VM is running in a genuine AMD SEV-SNP confidential computing environment Verifying the integrity of a confidential VM before trusting it with secrets Checking if SEV-SNP is available and properly configured Generating attestation reports for remote verification Validating AMD certificate chains (ARK → ASK → VCEK) Debugging attestation failures or certificate issues Keywords: SEV-SNP, attestation, confidential computing, AMD, VCEK, certificate chain, remote attestation, VM identity, TCB, measurement ### Workflow ┌─────────────────────────────────────────────────────────────────┐ │ SEV-SNP Attestation Flow │ └─────────────────────────────────────────────────────────────────┘ │ ▼ ┌─────────────────┐ │ 1.
