The developer-kit-python plugin provides specialized Python development tools including code review, refactoring, security assessment, architectural guidance, and production-ready patterns. It supports modern Python (3.11+) with focus on clean architecture, AWS Lambda integration, and best practices.

Components

Agents (4)

Agent	Purpose
`python-code-review-expert`	Code quality review and PEP standards compliance
`python-refactor-expert`	Clean code refactoring and design patterns
`python-security-expert`	Security vulnerability assessment (OWASP, CVEs)
`python-software-architect-expert`	Architecture design and scalability evaluation

Skills (2)

Skill	Purpose
`clean-architecture`	Clean Architecture, Hexagonal Architecture, and DDD patterns
`aws-lambda-python-integration`	AWS Lambda deployment with Chalice and raw Python approaches

Rules (4)

Rules activate automatically for all **/*.py files:

Rule	Purpose
`error-handling`	Exception hierarchies, logging, and recovery patterns
`language-best-practices`	Modern Python (3.11+) patterns, type hints, async
`naming-conventions`	PEP 8 naming standards for modules, classes, functions
`project-structure`	Modular project organization and layer separation

LSP Servers

The plugin includes LSP configuration for Python IDE support:

pyright-langserver: Fast, Microsoft TypeScript-based language server
pylsp: Python Language Server Protocol implementation

Note: LSP binaries must be installed separately. Install with: pip install pyright or pip install python-lsp-server

Installation

This plugin requires developer-kit-core:

claude plugin install ./plugins/developer-kit-python --scope project

Quick Start

Review Python code: Claude automatically invokes python-code-review-expert for code reviews
Refactor Python code: Use python-refactor-expert for clean code improvements
Security audit: Invoke python-security-expert for vulnerability assessment
Design architecture: Use python-software-architect-expert for architectural decisions
Apply patterns: Use /clean-architecture skill for layered architecture guidance
Deploy to AWS: Use /aws-lambda-python-integration for Lambda deployment patterns

Documentation

Guide	Content
Agent Guide	Detailed documentation for all 4 agents
Skills Guide	Architecture patterns for both skills
Rules Reference	Python coding rules and best practices
