SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the complexity of compiling type-annotated Python 3.14 code into standalone native binaries, ensuring strict type enforcement and high-performance execution without the need for an interpreter.

Core Features & Use Cases

  • AOT Compilation: Transforms standard typed Python source code into fast, standalone native binaries.
  • Type Enforcement: Validates type annotations at compile time, rejecting code that does not meet strict type safety standards.
  • Diagnostic Reporting: Provides human-readable or JSON-formatted diagnostics to help developers debug and refine their code.
  • Use Case: Use this skill to compile a performance-critical Python module into a native binary to eliminate runtime overhead and ensure type safety across the entire codebase.

Quick Start

Use the pycc skill to build the current project and report any type-checking diagnostics found in the source files.

FAQPage Schema
How do I compile typed Python into a native binary?

You can compile typed Python into a native binary by using an ahead-of-time compilation process that transforms type-annotated Python 3.14 source code into standalone executables. This enforces strict type safety and eliminates interpreter overhead.

What is ahead-of-time compilation for Python?

Ahead-of-time compilation for Python is the process of translating type-annotated source code directly into standalone native binaries before execution. It validates type annotations at compile time to ensure high-performance execution without an interpreter.

Do I need Rust installed to compile Python code ahead-of-time?

Yes, you need Rust 1.97 or later installed to compile Python code ahead-of-time. The compilation process relies on Rust to transform type-annotated Python 3.14 source files into standalone native binaries.

How do I get diagnostic reports for type-checking errors in compiled Python?

You can get type-checking diagnostic reports by compiling your typed Python source code, which generates human-readable or JSON-formatted diagnostics. These reports identify type safety violations to help you debug and refine your code.

What is the best way to eliminate runtime overhead for performance-critical Python modules?

The best way to eliminate runtime overhead is ahead-of-time compilation, which converts type-annotated Python 3.14 modules into fast native binaries. This approach enforces strict compile-time type checking while removing interpreter dependency.

What happens if my Python code does not meet strict type safety standards during compilation?

If your Python code does not meet strict type safety standards, the ahead-of-time compilation process will reject it. The compiler validates type annotations at compile time and provides diagnostic reports to help you fix the type errors.
