Install python-development for Codex and Claude Code

Installs for the current user
codex plugin marketplace add cjthompson/claude-code-config
codex plugin marketplace upgrade cjthompson
codex plugin add python-development@cjthompson

Paste and run these commands in a terminal with Codex. They add and refresh the cjthompson catalog, then install this plugin.

Compatibility: the page URL and API slug “python-development-4” remain stable.

  • Codex: python-development-4@agent-plugin-marketplace → python-development@cjthompson

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/cjthompson/claude-code-config

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/python-development/.

Included Skills6

dignified-pythonskills/dignified-python/SKILL.md

Apply opinionated, production-grade Python design and review standards. Use for substantial Python implementation, refactoring, API design, module design, exception boundaries, interfaces, or a deep code-quality review; not for a quick standalone script.

python-async-concurrencyskills/python-async-concurrency/SKILL.md

Design, implement, and debug Python asyncio and concurrent code with structured concurrency, bounded parallelism, cancellation safety, timeouts, cleanup, and clear error propagation. Use for async workflows, task orchestration, or choosing among concurrency models.

python-project-toolingskills/python-project-tooling/SKILL.md

Configure and maintain Python projects, dependencies, packaging, environments, linting, formatting, type checking, testing, builds, and publishing. Use for pyproject.toml, an existing repository toolchain, or repository-level Python tooling work, not for a standalone script.

python-testingskills/python-testing/SKILL.md

Design and implement robust Python tests with pytest, including unit and integration boundaries, fixtures, parametrization, failure cases, and optional property-based tests. Use when adding tests, repairing a test suite, or deciding how Python behavior should be verified.

python-typing-referenceskills/python-typing-reference/SKILL.md

Answer detailed or normative questions about Python's type system using the complete vendored typing specification. Use for subtle assignability, generics, variance, protocols, overloads, narrowing, qualifiers, TypedDict, or checker-semantics questions that exceed everyday annotation guidance.

tighten-python-typesskills/tighten-python-types/SKILL.md

Tighten annotations in existing Python code with a focused, low-churn workflow based on Honnibal's tighten-types skill. Use to improve changed files, remove avoidable Any, make container and return types precise, or reduce type-checker errors without broad refactoring.
