Structural code search and refactoring via ast-grep. Reach for this when Edit fails with 'old_string not unique', when refactoring across formatting variations, or when matching code shape rather than text.
Get an outline (functions/classes/exports) of a file or package without reading it whole. Use when the question is 'list/show/what's in' rather than 'where is' (search) or 'how does it work' (read).
Use when deciding whether to add a third-party dependency or library, or when evaluating an existing one (npm install, pip install, go get, cargo add, adding to a manifest). Covers crypto/security deps, the build-it-yourself threshold, and transitive-tree risk.
Use when working in a Python repo and about to run python, pip, pytest, ruff, mypy, or any Python tool. Resolves the project virtualenv and requires full ./venv/bin/<tool> paths in all commands, plan files, and subagent prompts. Never run bare pytest or python.
Use when producing substantial prose -- docs, READMEs, design notes, PR descriptions, commit messages, long explanations, or report writeups. The full Strunk & White economy rules, the cut-list of needless constructions, the AI-tell vocabulary blocklist, and cadence guidance. The two always-on guardrails (no em-dashes, avoid AI tells) live in AGENTS.md.
Extract a known field from a YAML file by running yq instead of reading the whole file.

When you need a specific field from a JSON file, reach for jq rather than
reading the whole file.
jq -r '.field' file.json
Three details easy to forget:
-r -- raw string output (no surrounding quotes)// "default" -- fallback when a field is missing or nullkeys[] -- list an object's property namesFor anything beyond this, man jq.
