Reviewing Python code for common anti-patterns to avoid

python-anti-patterns is an agent skill from the wshobson/agents collection that works as a checklist of common mistakes in Python code. It is meant to be read before a change is finalized, so an agent or developer can catch problems early instead of after they cause trouble. The checklist covers the mistakes that appear most often in real projects, and it starts with infrastructure anti-patterns, such as timeout and retry logic that is scattered across a codebase rather than managed in one place. The skill is a reference of things to avoid, and it says so: for guidance on positive patterns and how to structure an application, it points to the separate python-design-patterns skill. It applies when reviewing Python code before a merge, debugging mysterious issues that often trace back to a common mistake, teaching or learning good Python habits, establishing coding standards for a team, and refactoring legacy code that has accumulated problems over time. Because it is a checklist, its value depends on applying it to the code in front of you rather than reading it once. The agent can use it as a review pass over a diff or a module, and the team decides which findings matter for its own project. The skill is installed with the skills CLI from the wshobson/agents repository. Its skills.sh page showed about 13.0K installs and passing results from three security audits at the time of the scan.
