git-agent for Python

Conventional commits for Python projects, automatically

git-agent understands Django, Flask, FastAPI, and standard Python project layouts, discovering your working-tree changes and splitting them into meaningful atomic commits with properly scoped conventional messages.

git-agent outputfeat(users): guard against duplicate email on creation

- add UserAlreadyExistsError domain exception
- check for existing email before insert to avoid db constraint failures
- migrate payload.dict() to payload.model_dump() for Pydantic v2 compatibility

Prevents a 500 on duplicate-email POST /users; callers now receive a
clear exception they can map to 409 Conflict at the HTTP layer.

Why it works for Python

Recognizes Django, Flask, and FastAPI project layouts for accurate scope detection
Understands Pydantic model changes and migration diffs
Handles monorepo Python services independently, committing each service atomically
Works with pyproject.toml and setup.cfg-based projects out of the box

install

brew install gitagenthq/tap/git-agent
# inside your Python repo
git-agent init   # detects pyproject.toml / setup.cfg and suggests scopes

FAQ

Does git-agent work with Django migrations?

Yes. git-agent detects migration files and treats them as a separate atomic commit with scope migrations, keeping them out of your feature commits.

Can I use git-agent with a virtual environment or conda?

git-agent is a standalone Go binary installed via Homebrew. It does not run inside your Python environment, requires no pip install, and owns the Git handoff from the repository working tree.

How does git-agent determine scopes for Python projects?

Running git-agent init scans your git history to infer scopes from your directory structure, then writes them to .git-agent/config.yml for consistent scope suggestions.
