{"agent":"claude","input":"Run the test suite of this Elixir project with coverage: mix test --cover --export-coverage default, then mix test.coverage, against a Postgres the way .github/workflows/main.yml does with MIX_ENV=test. Cross the per-module listing with the modules under lib/ that have no test file of their own, and pick the five least-covered that hold real logic. Write ExUnit tests for them using the project's own cases from test/support (DataCase, ConnCase), the factory and the Mox mocks in test/support/mocks.ex; test behaviour through public functions, not implementation details, and never stub the module under test. Do not change production code unless a test reveals a bug; if it does, fix it in a separate commit and say so. Run mix test, mix format --check-formatted and mix compile --warnings-as-errors, and open a pull request with the per-module coverage before and after.","resources":[{"url":"https://github.com/your-org/your-app"}]}
