Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
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.
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.
A zero-dependency Python tool for checking website availability, measuring response times, and detecting content changes. Uses only Python's standard library (urllib) — no requests, no aiohttp, no external packages.
Uptime checking: Verify any URL returns the expected HTTP status code Response time measurement: Precise millisecond timing for each request Content change detection: SHA-256 based hashing to detect when page content changes between checks Text verification: Confirm that specific text appears in the response body Multi-URL support: Check multiple sites in a single command JSON output: Machine-readable output for integration with other tools and dashboards Exit codes: Returns exit code 1 if any site is down, making it perfect for shell scripts and cron jobs
Simple uptime check: python main.py https://example.com # ✅ https://example.com # Status: 200 # Response: 142ms # Size: 1256 bytes # Hash: fb91d75a6bb43078 Check multiple sites at once: python main.py example.com google.com github.com Detect content changes (compare against a previous hash): python main.py https://example.com --hash-check fb91d75a6bb43078 # Shows "Changed: YES ⚠️" or "Changed: No" Verify a page contains expected text: python main.py https://status.example.com --contains "All Systems Operational" Expect a specific status code (e.g., redirect): python main.py https://old.example.com --expect 301 JSON output for scripting: python main.py example.com github.com --json | jq '.[] | select(.up == false)' Use in a cron job or script: python main.py https://mysite.com || echo "ALERT: Site is down!" | mail -s "Downtime Alert" admin@example.com
urls — One or more URLs to check (auto-prepends https:// if missing) --timeout N — Request timeout in seconds (default: 10) --expect N — Expected HTTP status code (default: 200) --contains TEXT — Verify response body contains this string --hash-check HASH — Previous content hash to compare against for change detection --json — Output results as JSON array
0 — All sites are up and match expectations 1 — One or more sites are down or failed checks
