FixProve

Prove your code. Don't hope it.

FixProve checks every import, every call, every attribute your AI wrote — against what's actually installed. Deterministically. No model in the loop.

$ pip install fixprove
$ npm install -g fixprove
$ fixprove check /path/to/your/project

One command. Read the source. See exactly what it checks. The npm package wraps the Python resolver engine — install both, or pip install fixprove alone if you don't need the npm entrypoint.

The GitHub App runs the same check as a blocking status on pull requests — currently limited to internal use, not yet open for third-party installation, with no paid tier yet. Only finding fragments (file paths, line numbers, the unresolved expression) transit our endpoint, encrypted and never persisted — see our Privacy Policy.

The problem

AI coding assistants write code fast, and they write it fluently — which is exactly why hallucinated imports, renamed methods, and non-existent API calls slip past review. They look correct. They are not.

--- a/report.py
+++ b/report.py
+ df = pd.read_exel("data.xlsx") # pandas has no read_exel
+ from fastapi_helpers import cache # not installed

FixProve catches this class of bug deterministically — no probabilistic model, no false-positive guesswork — by resolving every reference in a diff against your actual installed dependencies.
