Included Skills6

cmux-browser-cache-clearingskills/cmux-browser-cache-clearing/SKILL.md

Clear stale cmux browser cache/state when a page, image, or asset renders incorrectly in cmux but works in other browsers. Use especially when the last image on a page remains broken after content and media URLs are correct.

cmux-browser-chatgptingskills/cmux-browser-chatgpting/SKILL.md

This skill should be used when the user asks to "ask ChatGPT", "frag ChatGPT", "send a question to ChatGPT", "schick das an ChatGPT", "frag GPT ob", "ask GPT something", or wants to type a question into the ChatGPT browser surface open in cmux and read the response.

cmux-browser-content-readingskills/cmux-browser-content-reading/SKILL.md

This skill should be used when the user asks to "read the browser content", "read the cmux browser page", "what does the browser show", "what does the GitHub browser show", "what's on this page", "get the page text", "extract text from the browser", "summarize the page", "read the open tab", or wants to read/extract text from an already-open browser surface in cmux without navigating anywhere.

cmux-browser-navigatingskills/cmux-browser-navigating/SKILL.md

This skill should be used when the user wants to navigate the cmux browser pane to a URL without taking a screenshot — for example when they say "just navigate", "navigate only", "point the browser at", "don't screenshot", or "navigate to URL without a screenshot". Use cmux-browser-screenshooting instead when a visual capture is also needed.

cmux-browser-screenshootingskills/cmux-browser-screenshooting/SKILL.md

This skill should be used when the user asks to "take a screenshot", "screenshot the browser", "show me the browser", "capture the screen", "screenshot storybook", "open storybook in browser", "navigate to URL", "open URL in cmux", or wants to visually verify what is currently shown in a browser, open a new browser pane, or navigate an existing browser to a specific URL before screenshotting. Always use this skill instead of mcp__chrome-devtools__take_screenshot — cmux is token-efficient.

cmux-file-previewingskills/cmux-file-previewing/SKILL.md

This skill should be used when the user asks to "preview this file", "open file in cmux", "show file in preview pane", "preview these files", or "open [filename] in the preview pane", or wants to open one or more files as viewer tabs in a dedicated cmux pane. Reuses the same pane across calls by caching the pane ref — repeated previews accumulate as tabs in one pane instead of scattering across the workspace.
