Python tooling expertise for uv, Hatchling, ty type checker, pre-commit, TOML editing, and PyPI packaging. Activates on uv commands, pyproject.toml configuration, type checker setup, build system, git hooks, packaging, or release workflows.
Set up CI/CD pipeline for Python package publishing to PyPI. Use when preparing to publish a package, when setting up automated releases, or when configuring GitHub Actions or GitLab CI for Python projects.
Use when creating a README for a Python package, preparing for PyPI publication, fixing README rendering errors found by twine check, choosing between README.md and README.rst, or configuring the readme field in pyproject.toml. Generates professional, PyPI-compliant README files.
Use when you want to expand Ruff rule coverage in a Python repository using adopt-ruff suggestions.
Use when reading or writing pyproject.toml or .toml config files in Python, editing TOML while preserving comments and formatting, designing configuration file formats for Python tools, working with tomlkit or tomllib, or implementing atomic config file updates.
Configure pyproject.toml and Python packaging for distribution. Use when setting up a new Python package, when configuring build tools and dependencies, or when preparing a project for PyPI publishing.
LAST RESORT for stdlib-only Python 3.11+ scripts in CONFIRMED restricted environments (airgapped systems, no uv, no internet access). Creates portable dependency-free scripts using argparse, logging, config management (JSON/TOML/INI), and cross-platform patterns. Use ONLY when environment restrictions prevent Typer+Rich with PEP 723. Triggers on "stdlib-only script", "no dependencies", "airgapped", "restricted environment", "portable script no network". For standard CLI development, use python-cli-architect with Typer+Rich instead.
Use when working with Hatchling — configuring build system setup, pyproject.toml metadata, dependencies, entry points, build hooks, version management, wheel and sdist builds, package distribution, setuptools migration, or troubleshooting Hatchling build errors. Covers PEP 517/518/621/660 standards.
Use when creating a README for a Python package, preparing for PyPI publication, fixing README rendering errors found by twine check, choosing between README.md and README.rst, or configuring the readme field in pyproject.toml. Generates professional, PyPI-compliant README files.
This skill should be used when the user asks to install Perl modules, use cpanm, create a cpanfile, manage Perl dependencies, set up Carton, configure local lib, or mentions CPAN, cpanminus, module installation, or Perl package management.
Use when working with ty — running Python type checks, configuring ty.toml or pyproject.toml, suppressing diagnostics, interpreting error codes, targeting Python versions, or integrating ty with editors and CI. Covers CLI flags, configuration schema, rule severity, suppression comments, environment discovery, module resolution, and all installation methods.
Use when working with Astral's uv — managing Python project dependencies, creating PEP 723 scripts, installing tools, managing Python versions, configuring package indexes, or migrating from pip/poetry. Covers project initialization, virtual environments, workspace configuration, and CI/CD integration.
Creates or regenerates .dh/skill_discovery.yaml. Scans repo to infer tech stack, inventories installed skills via npx skills list, loads candidate skill content before suggesting, and writes a config-driven skill injection file. Run /dh:setup-skill-discovery to create or update the project skill discovery config.
Universal release workflow. Auto-detects version files and changelogs. Supports Node.js, Python, Rust, Claude Plugin, and generic projects. Use when user says "release", "发布", "new version", "bump version", "push", "推送".
Set up CI/CD pipeline for Python package publishing to PyPI. Use when preparing to publish a package, when setting up automated releases, or when configuring GitHub Actions or GitLab CI for Python projects.
Integrate reusable image template resources into the IAA repository through the standard resources-to-R.py pipeline. Use when Codex needs to turn a captured image patch into a formal template under `resources/`, add or update a `*.png.json` resource definition, run `tools/make_resources.py`, verify the generated prefab appears in `iaa/tasks/R.py`, or replace ad-hoc image path loading with generated `R.*` references.
Python development best practices including PEP 8 style guidelines, type hints, docstring conventions, and common patterns. Use when writing or modifying Python code.
This skill upgrades NixOS to a new release version (e.g., 25.05 → 25.11). Triggers: "upgrade nixos", "upgrade to new release", "update nixos version", "move to nixos 25.11", "nixos release upgrade", "upgrade system version". Researches breaking changes, updates flake inputs, guides through upgrade. Not for flake.lock updates within same release (use upgrade-flake for that).
