Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
The site-performance-watch skill monitors website performance metrics and provides alerts when thresholds are breached. It allows users to track key indicators like page load times, server response times, and error rates. This helps proactively identify and address potential issues impacting user experience and site availability.
When to use it
- Proactive Monitoring: Regularly check a live website's performance to catch slowdowns before they impact visitors.
- Post-Deployment Validation: Verify that new code deployments haven’t introduced performance regressions.
- Incident Response: Quickly determine if a reported site issue is due to performance degradation.
- Scheduled Reporting: Generate automated reports on website performance trends over time.
Key capabilities
- Website Performance Monitoring
- Threshold-based Alerting
- Metric Tracking (page load times, server response times, error rates)
Example prompts
- "Monitor my website at
https://www.example.comand alert me if the average page load time exceeds 3 seconds." - “Show me a graph of my site’s performance over the last 24 hours.”
- "What is the current error rate for
https://api.example.com?"
Tips & gotchas
The skill requires access to website metrics, which may involve configuring integrations with monitoring services or providing appropriate credentials. Ensure you have sufficient permissions to monitor the target websites.
