SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps users quickly read and summarize content from local text-based files, reducing manual scanning of large documents.

Core Features & Use Cases

  • Read common text formats such as .txt, .md, .json, .yaml/.yml, .csv/.tsv, .log, .sql, .ini, .toml, .py, .js, .html, and .xml.
  • For JSON/YAML, list top-level keys and important fields; for CSV/TSV, show header row plus a sample of rows and provide a concise summary.
  • Large logs: when files are large, fetch a meaningful window (e.g., tail) and summarize recent errors or notable patterns.
  • Out of scope: PDFs, Office documents, images, audio, and video. Use dedicated skills/tools for those formats.
  • Safety and best practices: never execute untrusted files; prefer reading the smallest portion necessary and avoid exposing secrets.
