chump-server 0.0.17

Python backend for the chump coding assistant

chump-server

The backend hosts ChumpAgent instances over ai-query's built-in agent server routes.

Run

uv sync
uv run chump-server

Install

Once published, the backend package can be installed or run directly with uv:

uv tool install chump-server
chump-server

or:

uvx --from chump-server chump-server

During repository development, uv still uses the local editable ../ai-query source from pyproject.toml.

Release

chump-server versions come from git tags through hatch-vcs.

git tag chump-server-v0.1.0
git push origin chump-server-v0.1.0

Pushing a chump-server-v* tag runs the PyPI job and creates a GitHub Release in .github/workflows/release.yml.
