Context Navigator · ultradd bundle Bootstrap, navigate, maintain, and validate lightweight index systems for Markdown-heavy workspaces through hierarchical CONTEXT.md and INDEX.md files. Use when a user asks to make a docs folder, Obsidian vault, decision log, personal knowledge base, research folder, or project workspace AI-readable; asks where to start reading without recursively scanning every Markdown file; asks to create, review, repair, or validate workspace/domain indexes; or when existing indexes are missing, stale, or inconsistent. Do not use as the primary codebase navigation tool for ordinary TypeScript/Python/etc. source analysis, single-file edits, small bug fixes, or repositories whose useful entry points are package manifests, types, tests, and source structure rather than Markdown docs. When the user explicitly says to use this skill for a change that will create or edit files, first present a concise change plan and wait for confirmation before modifying files.
