python-packaging
Create distributable Python packages with proper project structure, setup.py/pyproject.toml, and publishing to PyPI. Use when packaging Python libraries, creating CLI tools, or distributing Python code.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-crafted skill description that excels across all dimensions. It uses third person voice, provides specific concrete actions, includes natural trigger terms users would actually say, and clearly distinguishes itself from general Python development skills by focusing on the packaging/distribution niche.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Create distributable Python packages', 'proper project structure', 'setup.py/pyproject.toml', and 'publishing to PyPI'. These are concrete, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what ('Create distributable Python packages with proper project structure, setup.py/pyproject.toml, and publishing to PyPI') and when ('Use when packaging Python libraries, creating CLI tools, or distributing Python code') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'Python packages', 'setup.py', 'pyproject.toml', 'PyPI', 'packaging Python libraries', 'CLI tools', 'distributing Python code'. Good coverage of common terms and file names. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on Python packaging and distribution. The specific mentions of PyPI, setup.py, pyproject.toml, and package distribution create distinct triggers unlikely to conflict with general Python coding skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
42%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides excellent actionable content with complete, executable examples covering many Python packaging scenarios. However, it severely violates token efficiency by including far too much content inline, explaining concepts Claude already knows, and failing to use progressive disclosure. The skill would benefit greatly from being split into a concise overview with references to detailed pattern files.
Suggestions
Reduce to 3-5 essential patterns in SKILL.md and move advanced patterns (namespace packages, C extensions, multi-architecture wheels) to separate reference files
Remove explanatory text about basic concepts (what semantic versioning means, what wheels are) and trust Claude's existing knowledge
Add explicit validation steps to the build/publish workflow: 'If twine check fails, fix metadata and rebuild before proceeding'
Create a clear navigation structure at the top linking to separate files: PATTERNS.md, CLI.md, PUBLISHING.md, ADVANCED.md
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose at 600+ lines with extensive explanations of concepts Claude already knows (what semantic versioning is, what wheels are, basic Python packaging concepts). Includes 20 patterns when 3-5 would suffice for most use cases. | 1 / 3 |
Actionability | Provides fully executable, copy-paste ready code examples throughout. Every pattern includes complete pyproject.toml configurations, working Python code, and specific bash commands that can be used immediately. | 3 / 3 |
Workflow Clarity | Build and publish steps are listed but lack explicit validation checkpoints. The 'Checklist for Publishing' is helpful but appears at the end rather than integrated into workflows. No feedback loops for error recovery during build/publish process. | 2 / 3 |
Progressive Disclosure | Monolithic wall of text with all 20 patterns inline. No references to external files for advanced topics. Content that should be split (CLI patterns, C extensions, namespace packages) is all in one massive document with poor navigation. | 1 / 3 |
Total | 7 / 12 Passed |
