async-python-patterns

Python asyncio, concurrent programming, and async/await patterns for high-performance applications.

pydantic

Python data validation using type hints and runtime type checking with Pydantic v2's Rust-powered core.

python-api-docs

Render Python docstrings into a browsable, published API reference with Sphinx, autodoc, napoleon, and MyST.

python-code-style

Python code style, linting, formatting, naming conventions, and documentation standards.

python-configuration

Python configuration management via environment variables and typed settings.

python-error-handling

Python error handling patterns including input validation, exception hierarchies, and partial failure handling.

python-observability

Python observability patterns including structured logging, metrics, and distributed tracing.

python-patterns

Pythonic idioms, PEP 8 standards, type hints, and best practices for building robust, efficient, and maintainable Python applications.

python-resilience

Python resilience patterns including automatic retries, exponential backoff, timeouts, and fault-tolerant decorators.

python-type-safety

Python type safety with type hints, generics, protocols, and strict type checking.

uv-package-manager

The uv package manager for fast Python dependency management, virtual environments, and modern project workflows.

Language-agnostic structural craft -- decompose on responsibility not size, prefer deep modules over shallow piles, and shape cohesion, coupling, interfaces, error contracts, and data invariants. Sibling to code-hygiene, comment-hygiene and readable-code.

readable-code

Language-agnostic local-clarity craft -- shape control flow, the naming of a whole set, and reading order so a body reads straight down with the smallest working set. Sibling to code-hygiene, comment-hygiene and code-structure.

docs-patterns

Documentation writing conventions -- style, structure, tone, and quality standards.

claude-config

How agents, skills, and commands work in Claude Code projects.

code-hygiene

Language-agnostic code hygiene -- no dead/reinvented/duplicated code, truthful names, real implementations, and scoped (never blanket) diagnostic suppressions.

Web & Frontend Listed

frontend-patterns

CSS design system principles -- token usage, semantic layering, mobile-first, component isolation.

plan-issue

Analyze a GitHub issue and create an implementation plan

review-severity

One severity model for code review -- Critical/Important/Minor by consequence-if-shipped (impact x reachability), with confidence as a separate report gate.

python-anti-patterns

Common Python anti-patterns and a pre-merge review checklist.

python-packaging

Create distributable Python packages with proper project structure, pyproject.toml, and publishing to PyPI.

python-project-structure

Python project organization, module architecture, and public API design.

Testing & QA Listed

python-testing

Python testing strategies using pytest, TDD methodology, fixtures, mocking, parametrization, and coverage requirements.

recursive-development

Core principles for recursive multi-agent development -- nesting, scope ownership, TDD, context flow, token economics.

recursive-execution

Wave execution rules -- agent constraints, wave barriers, review-fix evaluation, language awareness.

recursive-planning

How to decompose projects into wave plans -- module identification, dependency mapping, wave assignment, contract guidance, deliverables.

recursive-quality

Quality patterns, anti-patterns, and contract richness guidelines for recursive development.

comment-hygiene

Comment truthfulness -- what a comment must tell the reader that the code can't, the KEEP/DELETE/EXEMPT/CONDITIONAL taxonomy, tombstone and retold-fact detection, and comment density across a diff. Sibling to code-hygiene, code-structure and readable-code.
