# Send SkillGuard by Farnwick 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": "farnwick-skillguard", "name": "SkillGuard by Farnwick", "source": "tencent", "type": "skill", "category": "安全合规", "sourceUrl": "https://clawhub.ai/FarnwickArglefax/farnwick-skillguard", "canonicalUrl": "https://clawhub.ai/FarnwickArglefax/farnwick-skillguard", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/farnwick-skillguard", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=farnwick-skillguard", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README.md", "SKILL.md", "prompts/security-analysis.txt", "skillguard.py" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "farnwick-skillguard", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-29T17:21:58.613Z", "expiresAt": "2026-05-06T17:21:58.613Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=farnwick-skillguard", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=farnwick-skillguard", "contentDisposition": "attachment; filename=\"farnwick-skillguard-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "farnwick-skillguard" }, "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/farnwick-skillguard" }, "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/farnwick-skillguard", "downloadUrl": "https://openagent3.xyz/downloads/farnwick-skillguard", "agentUrl": "https://openagent3.xyz/skills/farnwick-skillguard/agent", "manifestUrl": "https://openagent3.xyz/skills/farnwick-skillguard/agent.json", "briefUrl": "https://openagent3.xyz/skills/farnwick-skillguard/agent.md" } } ``` ## Documentation ### SkillGuard 🛡️ AI-powered security scanner for OpenClaw skills. Analyzes skill code for malicious behaviour before you install it. ### Scan before install (recommended) skillguard install Downloads the skill to a temp directory, runs AI security analysis, shows verdict, then asks for confirmation before installing via clawhub. Example: skillguard install my-new-skill ### Audit installed skills skillguard audit Scans all skills in /usr/lib/node_modules/openclaw/skills/, ~/.openclaw/workspace/skills/, and ~/.openclaw/skills/. Prints a table summary with details on any flagged skills. ### Scan a local path skillguard scan Scan any local skill directory without installing. Useful for reviewing skills you've already downloaded or developed locally. Example: skillguard scan ./my-skill-folder skillguard scan /usr/lib/node_modules/openclaw/skills/some-skill ### Risk Levels LevelMeaning✅ CLEANNo security issues detected🟡 LOWMinor concerns, generally safe⚠️ MEDIUMReview recommended before installing🚨 HIGHDangerous — do not install without careful manual review ### What Gets Checked Credential theft: Reads to ~/.ssh/, ~/.openclaw/, API keys, .env files Data exfiltration: curl/wget/fetch POSTing data to external servers Reverse shells: netcat, bash TCP redirects, socat to external IPs Privilege escalation: sudo abuse, setuid bits, writing to /etc/ Persistence: cron installs, systemd units, .bashrc modifications Obfuscation: base64-piped-to-bash, eval with dynamic content Package smuggling: undisclosed npm/pip installs Reconnaissance: network scanning, system info harvesting ### Usage by the AI Agent When the user asks to install a skill, use skillguard first: python3 /root/.openclaw/workspace/skills/skillguard/skillguard.py install When the user asks to check their installed skills for security issues: python3 /root/.openclaw/workspace/skills/skillguard/skillguard.py audit When the user asks to check a specific local skill directory: python3 /root/.openclaw/workspace/skills/skillguard/skillguard.py scan /path/to/skill ### Output Examples Clean skill: ✅ SkillGuard: good-skill — Clean. Installing... Flagged skill: 🚨 SkillGuard: bad-skill — Risk: HIGH Reads /root/.openclaw/*.json and POSTs to external IP. [HIGH] Data Exfiltration: curl POST of ~/.openclaw/openclaw.json to 45.33.32.156 [scripts/init.sh:14-22] [MEDIUM] Credential Theft: Reads ~/.ssh/id_rsa without disclosure [scripts/setup.sh:8] Install bad-skill anyway? (type YES to confirm) ### Requirements Python 3.6+ An Anthropic, OpenRouter, or DeepSeek API key configured in OpenClaw clawhub CLI (for install command only) ### Notes Binary files are automatically skipped Files larger than 100KB are truncated before analysis Analysis uses Claude Opus (or best available model) for maximum accuracy The scan itself is safe — skills are text files, not executed during scanning ## Trust - Source: tencent - Verification: Indexed source record - Publisher: FarnwickArglefax - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-29T17:21:58.613Z - Expires at: 2026-05-06T17:21:58.613Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/farnwick-skillguard) - [Send to Agent page](https://openagent3.xyz/skills/farnwick-skillguard/agent) - [JSON manifest](https://openagent3.xyz/skills/farnwick-skillguard/agent.json) - [Markdown brief](https://openagent3.xyz/skills/farnwick-skillguard/agent.md) - [Download page](https://openagent3.xyz/downloads/farnwick-skillguard)
