What problem does it solve? Research scattered across web pages, PDFs, and notes gets lost between sessions, forcing agents to re-fetch sources and re-derive facts every time. This Skill acquires, indexes, and summarizes document collections into persistent topic notebooks so answers come with citations from saved sources. ## Core Features & Use Cases - Source Acquisition: Fetches web pages via headless Chrome (puppeteer with stealth and robots.txt compliance) or Python fallback, downloads and extracts PDFs with page markers, and delegates batches of 3+ sources to parallel subagents. - Indexed Knowledge Base: Writes per-source metadata files, document summaries, and a topic index so queries search small metadata first and only escalate to raw documents when needed. - Persistent Memory: Appends durable facts, decisions, and preferences to notes files, supports global notebooks with checkout/check-in across workspaces, and exports snapshots for NotebookLM import. - Use Case: Researching TIPS ladder retirement strategies — the agent collects 15 sources into a tips-ladders notebook, extracts key facts with citations, and answers follow-up questions weeks later without re-fetching anything. ## Quick Start Ask the agent to research a topic and start a notebook, for example: "Research TIPS ladder strategies and save the sources in a notebook."
