Get the exact API of a Python module, class, or project file: every public name with its real signature and a one-line summary. Reads the installed package or parses the project file, so the answer is always current.

Use this INSTEAD OF reading a file when you need to know how to call something. It is typically 5-10x fewer tokens than the source and contains everything needed to make a correct call. Cheap enough to re-ask at any time rather than holding it in context.

Get everything you need to edit a file correctly, in one budgeted block: the file's own API plus the exact surface of every module it imports, followed transitively through project code.

Call this INSTEAD OF reading a file and its dependencies, before you start editing. It is a dependency closure computed from the code — not a similarity search — so it contains what the file actually uses, and it is typically several times cheaper than reading the same files. Ask again whenever you need it rather than holding it in context.

Check Python source for references that provably do not exist -- invented packages, invented methods on real libraries, helpers missing from this project. Returns the blocked references and the real API of whatever each one got wrong.

Run this on code you are about to write. It only reports what it can prove absent, so a clean result is meaningful and a block is never a guess.
