opengrok

Use this skill whenever the user wants to search, navigate, or understand source code in a large codebase — even when they don't say "OpenGrok". Trigger for: finding where a function or class is defined, tracking where something is called or referenced, reading a remote source file, checking who last changed a line (blame/annotate), browsing a directory tree, exploring commit history, or comparing code across projects. Activate when the user says "search the codebase", "find where X is defined", "who changed this", "show me the source for", "look up that function", or mentions cross-referencing or OpenGrok by name. If the target code lives on a remote server or indexed repository rather than locally, this skill applies.
