 "title": "Find where a behavior lives in an unfamiliar repo",
 "page_title": "How to find where a behavior lives in an unfamiliar repo with Jevgrep",
 "summary": "Ask a plain question about behavior and get exact code excerpts with line numbers.",
 "who": "A developer who has been asked to change a feature in a codebase they do not know and does not know the file or function names.",
 "problem": "Keyword search needs an exact identifier, and reading many files to guess where logic lives costs time and context.",
 "outcome": "A ranked set of original source excerpts with paths and line numbers that point to the code handling the behavior.",
 "steps": [
  "Run `npm install -g @nassim-arifette/jevgrep`",
  "Run `jevgrep init --global`",
  "Run `cd path/to/my-project` and then `jevgrep init`, answering `y` only after you have reviewed the scope",
  "Run `jevgrep inspect` to confirm which files are eligible and what is excluded",
  "Run `jevgrep search --query \"Where is session expiry handled?\"`"
 ],
 "agent_prompt": "Using the JevGrep CLI in the repository at <repo path>, run `jevgrep search --query \"<behavior question>\"` and list each returned excerpt with its path and line range. Verify that the result reports complete coverage before treating an empty or short result as meaningful.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "Eligible source fragments are sent to the configured provider, and the search is not a substitute for exact tools such as rg when you already know the symbol.",
