Install python for Codex and Claude Code

Installs for the current user
claude plugin marketplace add IchenDEV/agent-plugin-mkt
claude plugin marketplace update agent-plugin-marketplace
claude plugin install python-3@agent-plugin-marketplace

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

Compatibility: the page URL and API slug “python-3” remain stable.

  • Codex: Legacy selector python-3@agent-plugin-marketplace remains documented for migration; install from source for this runtime.

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.

Codex has another source with the same manifest name. This directory does not invent numbered install aliases; use the publisher's catalog or inspect the source manually for that runtime.

Get the source manually
git clone https://github.com/outcomeeng/plugins

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

Included Skills9

architect-pythonskills/architect-python/SKILL.md

ALWAYS invoke this skill when writing ADRs for Python. NEVER author a Python ADR without this skill.

audit-python-architectureskills/audit-python-architecture/SKILL.md

Python-specific architecture audit — judges the Python architecture target in scope for dependency injection, mocking prohibition, execution-level accuracy, Python anti-patterns, and test-double exception cases.

audit-python-codeskills/audit-python-code/SKILL.md

Python implementation-code audit methodology — judges the Python code files in scope for design flaws and architecture-decision compliance.

audit-python-testsskills/audit-python-tests/SKILL.md

Python test-evidence audit methodology — judges the Python tests in scope against the spec-tree and Python-specific evidence properties.

code-pythonskills/code-python/SKILL.md

ALWAYS invoke this skill when writing or fixing implementation code for Python. NEVER write or fix Python implementation without this skill.

python-architecture-standardsskills/python-architecture-standards/SKILL.md

Python ADR conventions enforced across architect and auditor skills. Loaded by other skills, not invoked directly.

python-standardsskills/python-standards/SKILL.md

Python code standards enforced across all skills. Loaded by other skills, not invoked directly.

python-test-standardsskills/python-test-standards/SKILL.md

Python test standards enforced across all skills. Loaded by other skills, not invoked directly.

test-pythonskills/test-python/SKILL.md
