fixprove (Python engine, open-core)

FixProve deterministically verifies that every import, symbol, method, and API call in your code — Python or TypeScript/JavaScript — resolves against your real, installed dependencies. No LLM calls, no false-positive-prone heuristics: an AST-level resolver checks a reference set against a knowledge base built from what's actually on disk.

pip install fixprove
fixprove /path/to/your/project

Exit codes: 0 clean, 1 unresolved symbol(s) found, 2 usage/setup error — designed to drop straight into a CI gate.

This is the same engine that powers the FixProve GitHub App, which posts this check as a blocking status directly on your pull requests — without your source code ever leaving your own CI runner. This CLI is the open-core, self-hosted way to run the identical deterministic core locally or in your own pipeline.

Scope (current)

Python: imports, call targets, attribute chains, checked against installed packages' real public API.
TypeScript/JavaScript: imports/re-exports/call targets/attribute chains, checked against installed npm packages' .d.ts declarations.
Known limitation: packages using TypeScript module augmentation (e.g. @types/lodash) are safely skipped (never flagged, but also not fully checked) rather than guessed at — see the engine's own Keystone Reports (KS-REPORT-1.4-ts-resolver.md in the source repository) for the full accuracy/limitation writeup.
