Gemini CLIAbout this skill
Read a large Markdown file efficiently using md2idx: first fetch the numbered index (table of contents), then retrieve only the sections relevant to the current task — instead of loading the entire file into context. Use this skill whenever asked to read, analyze, summarize, or answer questions about a Markdown file that is likely to be large (more than 200 lines or 10 KB), or when the user explicitly mentions md2idx or asks to "read via index", "read selectively", "check the TOC first". Also consider this skill proactively when you encounter a large .md file and don't need every section — partial retrieval saves tokens and keeps context focused. Do NOT use this skill for small files, files you need to edit in full, or non-Markdown files.
