Description

Adds one skill:

• skills/curlshot/SKILL.md: capturing a web page as an image (PNG, JPEG, WebP), a PDF, or a scrolling video (MP4, WebM, GIF) with one HTTP request to the CurlShot screenshot API, plus rendering local HTML or Markdown to an image or PDF via a POST body. It covers the curl -G --data-urlencode call pattern, a table of the common options (full page, device presets, viewport, dark mode, element selector, cookie-banner/ad blocking, wait conditions, cache), how errors come back (JSON error_code / error_message, unknown options rejected rather than ignored), and the hosted MCP server as an alternative for MCP-capable agents.

Requirements and limitations are stated in the skill: it is a hosted, paid service with a free tier (100 screenshots/month, no card; paid plans from $19/month), it needs an access key in CURLSHOT_API_KEY, the key must never be printed or committed, and localhost/private-network URLs are refused (send the page HTML instead). Links point only to the docs, the signup page needed to get a key, and the MIT-licensed source repo the skill comes from (https://github.com/SergiuPogor/curlshot-mcp).

Disclosure: I build CurlShot.

Additional Notes

npm run skill:validate passes (all 436 skills valid, including curlshot), npx @microsoft/vally-cli lint skills/curlshot passes (2/2 checks), and npm run build regenerated docs/README.skills.md (one added row, included in this commit). Line endings normalized with bash eng/fix-line-endings.sh. The skill's API examples have not been run through GitHub Copilot itself, hence the unchecked box above. This PR was prepared with an AI coding agent.
