One loadout uses Pydantic so far. It lists rules, skills and MCP configs with install paths for every supported agent.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
Stop agents writing class Config, orm_mode, @validator, .dict() and pydantic.v1 into FastAPI apps on Pydantic v2, and catch Optional fields that became required.
Tools these loadouts expect: python3, uv. Not sure what your agent will load once they're in? Check your setup or see which files each agent reads.
Run the tests with the framework's deprecation warnings as errors, scan for v1 or pre-6.1 patterns, give every optional field a default, and use FETCH_RAISE in list-view tests.
