Install plugin

Installs for the current user
codex plugin marketplace add IchenDEV/agent-plugin-mkt
codex plugin marketplace upgrade agent-plugin-marketplace
codex plugin add python-development-3@agent-plugin-marketplace

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

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/acaprino/daodan

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

Included Skills9

async-python-patternsskills/async-python-patterns/SKILL.md

Structure asyncio code: task management, cancellation, rate limiting, blocking calls kept off the event loop. TRIGGER WHEN: building async APIs, concurrent or I/O-bound systems needing non-blocking operations, or choosing between asyncio, threading and multiprocessing.

pydantic-v2skills/pydantic-v2/SKILL.md

Deep reference for the data layer of a production service. TRIGGER WHEN: writing or refactoring Pydantic v2 models in Python 3.10+; migrating a codebase from Pydantic v1 to v2; choosing between `Annotated[Decimal, ...]` and `condecimal` for money; hitting v2 validator, serialization or performance surprises; designing FastAPI request/response schemas or error envelopes. DO NOT TRIGGER WHEN: the task is Python testing (use python-tdd) or non-Python schema work (use typescript-development).

python-commentsskills/python-comments/SKILL.md

Grade and rewrite code prose against antirez's 9-type taxonomy, mapped to PEP 257. TRIGGER WHEN: the user asks to improve comments, add docstrings, review comment quality, or audit documentation in a Python codebase.

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

Find and remove unused variables, functions, classes and unreachable branches with vulture and ruff, filtering framework false positives (Django, FastAPI, pytest, click). TRIGGER WHEN: cleaning up Python codebases, enforcing import hygiene, or integrating dead code checks into CI.

python-packagingskills/python-packaging/SKILL.md

Build wheels and sdists from a pyproject.toml, then publish them. TRIGGER WHEN: packaging Python libraries, choosing a src or flat layout, setting up dynamic versioning, creating CLI entry points, or uploading to TestPyPI and PyPI.

python-performance-optimizationskills/python-performance-optimization/SKILL.md

Measure first with cProfile, line_profiler, memory_profiler or py-spy, then fix what the numbers show. TRIGGER WHEN: debugging slow Python code, optimizing bottlenecks, cutting memory usage, or improving application performance.

python-refactorskills/python-refactor/SKILL.md

Restructure tangled code into a clear equivalent, preserving behavior. TRIGGER WHEN: the user asks for "readable", "maintainable" or "clean" code, a review flags comprehension issues, or the task is legacy modernization or onboarding cleanup.

python-tddskills/python-tdd/SKILL.md

Generate suites that pin behavior instead of implementation. TRIGGER WHEN: writing Python tests, improving coverage, reviewing test quality, or practicing red-green-refactor workflows with pytest. DO NOT TRIGGER WHEN: the target is non-Python (use mattpocock-skills:tdd for other languages, or developer-essentials:e2e-testing-patterns for browser E2E).

uv-package-managerskills/uv-package-manager/SKILL.md

Handle virtual environments, lockfiles and interpreter version pinning. TRIGGER WHEN: setting up Python projects, managing dependencies, migrating off pip/poetry, or optimizing Python development workflows with uv.
