# Send Arc Sentinel 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-sentinel", "name": "Arc Sentinel", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/arc-claw-bot/arc-sentinel", "canonicalUrl": "https://clawhub.ai/arc-claw-bot/arc-sentinel", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/arc-sentinel", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-sentinel", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "credential-tracker.json", "package.json", "scripts/full-audit.sh", "scripts/git-hygiene.sh", "scripts/permission-auditor.sh" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "arc-sentinel", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T03:36:34.635Z", "expiresAt": "2026-05-07T03:36:34.635Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-sentinel", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=arc-sentinel", "contentDisposition": "attachment; filename=\"arc-sentinel-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "arc-sentinel" }, "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-sentinel" }, "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-sentinel", "downloadUrl": "https://openagent3.xyz/downloads/arc-sentinel", "agentUrl": "https://openagent3.xyz/skills/arc-sentinel/agent", "manifestUrl": "https://openagent3.xyz/skills/arc-sentinel/agent.json", "briefUrl": "https://openagent3.xyz/skills/arc-sentinel/agent.md" } } ``` ## Documentation ### Arc Sentinel Security monitoring toolkit for OpenClaw agents. Runs automated checks against your infrastructure and reports issues. ### Configuration Before first use, create sentinel.conf in the skill directory: cp sentinel.conf.example sentinel.conf Edit sentinel.conf with your values: DOMAINS — Space-separated list of domains to check SSL certificates GITHUB_USER — GitHub username for repo audits KNOWN_REPOS — Space-separated list of expected repo names (unexpected repos trigger warnings) MONITOR_EMAIL — Email address for HaveIBeenPwned breach checks HIBP_API_KEY — Optional; HIBP v3 API key ($3.50/mo) for automated breach lookups Also customize credential-tracker.json with your own credentials and rotation policies. A template is provided. ### Full scan cd bash sentinel.sh ### Output Formatted report to stdout with color-coded severity JSON report saved to reports/YYYY-MM-DD.json Exit codes: 0 = all clear, 1 = warnings, 2 = critical ### 1. SSL Certificate Expiry Check certificate expiry for configured domains. Warns at <30 days, critical at <14 days. ### 2. GitHub Security List repos and check Dependabot/vulnerability alert status Review recent account activity for anomalies Flag unexpected repositories ### 3. Breach Monitoring (HaveIBeenPwned) Query HIBP API for breached accounts (requires API key) Falls back to manual check URL if no key is set ### 4. Credential Rotation Tracking Read credential-tracker.json and flag credentials that are overdue, approaching expiry, or never rotated. Supports policies: quarterly (90d), 6_months (180d), annual (365d), auto. ### Additional Scripts ScriptPurposescripts/secret-scanner.shScan repos/files for leaked secrets and API keysscripts/git-hygiene.shAudit git history for security issuesscripts/token-watchdog.shMonitor token validity and expiryscripts/permission-auditor.shAudit file and access permissionsscripts/skill-auditor.shAudit installed skills for securityscripts/full-audit.shRun all scripts in sequence ### Agent Usage During heartbeats or on request: Run bash sentinel.sh from the skill directory Review output for WARN or CRITICAL items Report findings to the human if anything needs attention Update credential-tracker.json when credentials are rotated ### Cron Setup # Weekly Monday 9am 0 9 * * 1 cd /path/to/arc-sentinel && bash sentinel.sh >> reports/cron.log 2>&1 ### Requirements openssl (SSL checks) gh CLI authenticated (GitHub checks) curl (HIBP) python3 (JSON processing) ## Trust - Source: tencent - Verification: Indexed source record - Publisher: arc-claw-bot - 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: 2026-04-30T03:36:34.635Z - Expires at: 2026-05-07T03:36:34.635Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/arc-sentinel) - [Send to Agent page](https://openagent3.xyz/skills/arc-sentinel/agent) - [JSON manifest](https://openagent3.xyz/skills/arc-sentinel/agent.json) - [Markdown brief](https://openagent3.xyz/skills/arc-sentinel/agent.md) - [Download page](https://openagent3.xyz/downloads/arc-sentinel)
