# URL Summarize Skill Fetch a webpage and return a one-paragraph summary of its content. ## When to use The user wish contains a URL (http:// or https://) AND asks for a summary, gist, or explanation of what the page contains. Examples: - "summarize https://example.com" - "what does https://en.wikipedia.org/wiki/AI_agent say?" - "tell me about this page: https://blog.example.com/foo" ## Execution This skill uses a helper script to fetch the URL safely (with redirect handling and HTML text extraction). Steps: 1. Extract the URL from the user's wish. 2. Call the fetch script via `run_bash`: ``` python3 scripts/fetch.py "<URL>" ``` The script prints the page's text content to stdout (max 4000 chars). 3. Read the script's output. 4. Generate a one-paragraph summary based on the text. 5. Return the summary as the final response. ## Style - One paragraph, 3-5 sentences max. - Focus on what the page actually says, not on the URL or technical details. - If the page is empty, errors out, or has no readable text, say so plainly: "This page returned no extractable content." ## What this skill demonstrates This SKILL.md + scripts/ pattern is how Claude Code skills work when they need external data or computation. The SKILL.md is the entry point that the LLM reads. Scripts are invoked **by the LLM via run_bash**, not directly by the engine. This keeps the engine deterministic (it only reads SKILL.md and dispatches tool calls) while letting the LLM decide which scr
