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-bug-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 2d ago.

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 Packaging Bug Finder

Identifies known packaging and build issues for Python projects by searching GitHub repositories for relevant issues, analyzing their content and comments, and determining resolution status.

Instructions

When investigating packaging problems for a Python project, follow this workflow:

1. Find the Repository

Use the source finder skill to locate the project's GitHub repository:

Skill: python-packaging-source-finder
Args: <package_name>

If the skill returns a repository URL with high or medium confidence, proceed. If confidence is low or no URL found, stop here and return an error.

2. Search for Packaging Issues

Once you have the repository URL, search for packaging-related issues by:

  1. Access the GitHub issues page: Use WebFetch to get the repository's issues page (typically <repo_url>/issues)

  2. Filter for packaging keywords: Look for issues with titles containing:

    • Build-related: "build", "compilation", "compile", "setup.py", "pyproject.toml", "cmake", "makefile"
    • Installation: "install", "pip", "wheel", "package", "packaging", "distribution"
    • Environment: "gcc", "clang", "msvc", "python", "version", "dependency"
    • Platform: "windows", "linux", "macos", "arm64", "x86_64"
    • Errors: "error", "fail", "broken", "issue"
  3. Prioritize open issues: Focus on open issues first, then closed ones that might affect the target version

3. Analyze Each Relevant Issue

For each packaging-related issue found:

  1. Fetch issue details: Use WebFetch to get the full issue page including:

    • Issue description
    • All comments
    • Labels and milestones
    • Current status (open/closed)
  2. Extract key information:

    • Problem description: What packaging/build problem is described?
    • Affected versions: Which versions are mentioned as problematic?
    • Resolution status: Is it fixed, pending, or unresolved?
    • Available fixes: Are there PRs, commits, or workarounds mentioned?
    • Version inclusion: If fixed, in which version was the fix included?
