A build-configuration investigator for Python projects that finds environment variables used by wheel-building tools, compilers, and CMake.

In plain words
What is it for?
Use it to inspect setup.py, CMake files, build tools, and compiler variables such as CC, CXX, and build flags.
Why use it?
It helps you discover which settings can change a build and how to customize or troubleshoot it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

python-packaging-env-finder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/env_finder.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Python Build Environment Variables Investigation

This skill helps you discover all environment variables that can be set when building Python wheels for a project. It performs a comprehensive analysis of build configuration files to identify customizable environment variables used during the wheel building process.

Instructions

When a user asks about environment variables for building Python wheels, investigating build configuration, or understanding build customization options:

  1. Run the Environment Variables Investigation Script:

    ./scripts/env_finder.py [project_path]

  2. Analyze and present the findings focusing on:

    Build Configuration Variables

    • Setup.py Variables: Environment variables used in setup.py for customizing builds
    • CMake Variables: Variables defined in CMakeLists.txt and related files
    • Build Tool Variables: Variables used by setuptools, distutils, or other build systems
    • Compiler Variables: Variables affecting compilation (CC, CXX, CFLAGS, etc.)

    Variable Categories

    Compiler and Linker Variables
    • CC, CXX - Compiler selection
    • CFLAGS, CXXFLAGS - Compilation flags
    • LDFLAGS - Linker flags
    • LIBS - Additional libraries
    Path Configuration Variables
    • PREFIX - Installation prefix
    • LIBRARY_PATH - Library search paths
    • INCLUDE_PATH - Header file paths
    • PKG_CONFIG_PATH - pkg-config search paths
    Feature Control Variables
    • ENABLE_* - Feature enable/disable flags
    • WITH_* - Optional component inclusion
    • USE_* - Build option selection
    • DISABLE_* - Feature disable flags
    Python-Specific Variables
    • PYTHON_INCLUDE_DIR - Python headers location
    • PYTHON_LIBRARY - Python library path
    • SETUPTOOLS_* - Setuptools configuration
    • PIP_* - pip-related build variables

    Usage Context

    • When Variables Are Used: During which build phase each variable takes effect
    • Default Values: What happens when variables are not set
    • Required vs Optional: Which variables are mandatory for successful builds

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
