# Send Skill Scanner 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": "arc-skill-scanner", "name": "Skill Scanner", "source": "tencent", "type": "skill", "category": "安全合规", "sourceUrl": "https://clawhub.ai/Trypto1019/arc-skill-scanner", "canonicalUrl": "https://clawhub.ai/Trypto1019/arc-skill-scanner", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/arc-skill-scanner", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-skill-scanner", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "scripts/scanner.py" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "arc-skill-scanner", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-29T15:39:16.099Z", "expiresAt": "2026-05-06T15:39:16.099Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-skill-scanner", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-skill-scanner", "contentDisposition": "attachment; filename=\"arc-skill-scanner-1.4.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "arc-skill-scanner" }, "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/arc-skill-scanner" }, "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/arc-skill-scanner", "downloadUrl": "https://openagent3.xyz/downloads/arc-skill-scanner", "agentUrl": "https://openagent3.xyz/skills/arc-skill-scanner/agent", "manifestUrl": "https://openagent3.xyz/skills/arc-skill-scanner/agent.json", "briefUrl": "https://openagent3.xyz/skills/arc-skill-scanner/agent.md" } } ``` ## Documentation ### Skill Scanner Scan OpenClaw skills for security issues before you install them. 341 malicious skills were found on ClawHub — don't be the next victim. ### Why This Exists The ClawHub marketplace had 22-26% of skills flagged as containing vulnerabilities. Common attacks include: Credential stealers disguised as benign plugins Typosquatting (fake names similar to popular skills) Data exfiltration via hidden HTTP requests Obfuscated code hiding malicious payloads Prompt injection via SKILL.md content ### Scan a local skill directory python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/ ### Scan a SKILL.md file directly python3 {baseDir}/scripts/scanner.py scan --file ./SKILL.md ### Scan with verbose output python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/ --verbose ### Scan all installed skills python3 {baseDir}/scripts/scanner.py scan-all ### Scan with binary checksum verification python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/ --checksum checksums.json ### Generate checksums for binary assets python3 {baseDir}/scripts/scanner.py checksum --path ~/.openclaw/skills/some-skill/ -o checksums.json ### Verify checksums against a manifest python3 {baseDir}/scripts/scanner.py checksum --path ~/.openclaw/skills/some-skill/ --verify checksums.json ### Output as JSON python3 {baseDir}/scripts/scanner.py scan --path ./skill-dir/ --json ### SKILL.md Analysis Suspicious URLs (non-HTTPS, IP addresses, URL shorteners) Prompt injection patterns (hidden instructions, override attempts) Requests for credentials, API keys, or tokens Obfuscated or encoded content (base64, hex, unicode escapes) ### Script Analysis Network calls (curl, wget, requests, urllib, fetch) File system writes outside expected paths Environment variable access (credential harvesting) Shell command execution (os.system, subprocess, exec) Obfuscated strings (base64 decode, eval, exec) Data exfiltration patterns (POSTing to external URLs) Cryptocurrency wallet patterns Known malicious domains Dynamic instruction fetching (remote .md/.yaml/.json downloads) Fetch-and-execute patterns (remote code execution) Telemetry leaks (printenv, logging env vars/configs/secrets to stdout) Binary/asset risks (prebuilt executables, compiled code, library injection) Shell=True in subprocess calls (RCE risk) Path traversal patterns (directory escape via ../ sequences) ### Name Analysis Typosquatting detection (compares against known popular skills) Edit distance calculation to catch misspellings and character swaps ### Binary/Asset Checksum Verification SHA-256 checksums for all binary files (.exe, .dll, .so, .wasm, .pyc, etc.) Generate checksum manifests for trusted skill versions Verify binaries against expected checksums on update Flags unverified binaries and checksum mismatches (tampering detection) ### Metadata Analysis Excessive permission requirements Suspicious install scripts Env requirements that seem unnecessary ### Risk Levels CRITICAL — Almost certainly malicious. Do NOT install. HIGH — Likely malicious or extremely risky. Manual review required. MEDIUM — Suspicious patterns found. Review before installing. LOW — Minor concerns. Probably safe but worth checking. CLEAN — No issues detected. Safe to install. ### Tips Always scan before installing ANY third-party skill Even "CLEAN" results aren't a guarantee — this catches known patterns If a skill needs network access, verify the domains it contacts Cross-reference skill names with known typosquats When in doubt, read the source code yourself ## Trust - Source: tencent - Verification: Indexed source record - Publisher: Trypto1019 - Version: 1.4.0 ## 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: 2026-04-29T15:39:16.099Z - Expires at: 2026-05-06T15:39:16.099Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/arc-skill-scanner) - [Send to Agent page](https://openagent3.xyz/skills/arc-skill-scanner/agent) - [JSON manifest](https://openagent3.xyz/skills/arc-skill-scanner/agent.json) - [Markdown brief](https://openagent3.xyz/skills/arc-skill-scanner/agent.md) - [Download page](https://openagent3.xyz/downloads/arc-skill-scanner)
