Build modern Python web apps with Django and FastAPI, define SQLAlchemy models and Alembic migrations, write pytest tests, debug errors, and review code quality using specialized agents that orchestrate database tasks and full codebase reviews.
npx claudepluginhub majesticlabs-dev/majestic-marketplace --plugin majestic-pythonDatabase orchestrator for Python applications. Routes to specialized skills for models, queries, or migrations.
Orchestrate Python code reviews by selecting appropriate specialized agents based on changed files, loading project topics, and synthesizing results into prioritized findings.
Alembic database migrations for Python applications - setup, auto-generation, manual migrations, and safe deployment patterns.
Build Django applications with models, views, forms, templates, REST APIs, and modern Django 5.x patterns.
Build FastAPI applications with async patterns, Pydantic validation, dependency injection, and modern Python API practices.
Write pytest tests with fixtures, parametrization, mocking, async testing, and modern patterns. Use when creating or updating Python test files. Not for unittest — use standard library patterns instead.
Modern Python 3.12+ development with uv, ruff, and production-ready practices. Routes to specialized skills for frameworks and testing.
Debug Python errors, exceptions, and unexpected behavior. Analyzes tracebacks, reproduces issues, identifies root causes, and provides fixes.
Review Python code with high quality bar for type hints, Pythonic patterns, and maintainability.
SQLAlchemy 2.0 patterns - model definition, engine setup, async patterns, relationships, query optimization, repository pattern, and transactions.
Editorial "Python Pro" bundle for Claude Code from Antigravity Awesome Skills.
Python-specific validation, patterns, and expert agents
Python development with Django, FastAPI, async patterns, and uv package management
Python development capabilities
Opinionated Python 3.11+ engineering system. Establishes strong defaults (SOLID, typing policy, testing standards, code smell detection) and routes to specialist skills for TDD, CLI, web, data/science, and constrained environments.
Python, FastAPI, SQLAlchemy, PostgreSQL, and pytest code review. Pairs with beagle-core for full workflow.

Coding is no longer the bottleneck. Planning, review, and learning loops matter more than syntax. Each feature makes the next one easier to build.
| Step | What Happens | Key Tools |
|---|---|---|
| Plan | Agents research codebase + best practices, produce detailed implementation plans | /majestic:plan, architect agent |
| Work | Agents write code, tests, and iterate using real app feedback | /majestic:build-task, coder skills |
| Assess | Multi-angle review: security, performance, simplicity, conventions | /majestic:code-review, quality-gate |
| Reflect | Analyze session patterns, capture lessons so future agents improve | /majestic-tools:insight:reflect, /majestic:add-lesson |
See the Workflow Guide for detailed documentation.
Run the installer:
curl -fsSL https://raw.githubusercontent.com/majesticlabs-dev/majestic-marketplace/master/install.sh | bash
This gives you options to:
Run claude and add the marketplace:
/plugin marketplace add https://github.com/majesticlabs-dev/majestic-marketplace.git
Then install a plugin:
/plugin install {plugin-name}
Export Majestic plugins to OpenCode or Codex with schema-aware conversion:
./scripts/install-codex.sh
# Install all plugins
./scripts/install-codex.sh --all
# Install all plugins to OpenCode
./scripts/install-opencode.sh --all
# Install specific plugins
./scripts/install-codex.sh engineer rails tools
# Example (explicit): convert engineer, rails, and tools to OpenCode
# Output target: ~/.config/opencode
./scripts/install-opencode.sh engineer rails tools
# Install one plugin (short or prefixed)
./scripts/install-codex.sh engineer
./scripts/install-codex.sh majestic-tools
Both commands are now local to this repository and only require Ruby (scripts/convert-plugin.rb).
This runs a converter pipeline (not a plain file copy), so incompatible Claude metadata is translated for target formats.
disable-model-invocation frontmatter is preserved as part of source metadata parsing, but it does not exclude a command from conversion for OpenCode/Codex output.
Output locations:
~/.codex/skills/ and ~/.codex/prompts/~/.config/opencode (opencode.json, agents/, skills/, plugins/)Limitations: Codex still does not support some Claude Code features (Task, hooks, some MCP integrations), so behavior is reduced there.
