            ## Upgrade Checks Failure on Main Branch

            The upgrade checks workflow has failed on the main branch.

            **Workflow Run**: [#{{runNumber}}]({{serverUrl}}/{{repo.owner}}/{{repo.repo}}/actions/runs/{{runId}})
            **Commit**: {{sha}}
            **Branch**: {{ref}}
            **Event**: {{eventName}}

            ### Common causes

            - **ty (type checker)**: New ty releases frequently add stricter checks that flag previously-accepted code. Run `uv run ty check` locally with the latest ty to reproduce. Fix the type errors or bump the ty version floor in `pyproject.toml`.
            - **ruff**: New lint rules or stricter defaults in a ruff upgrade.
            - **MCP SDK**: Breaking changes in the `mcp` package (new method signatures, renamed types).

            ### What to do

            1. Check the workflow logs to identify which job failed (static analysis vs tests)
            2. Reproduce locally with `uv sync --upgrade && uv run prek run --all-files && uv run pytest -n auto`
            3. Fix the code or adjust dependency constraints as needed
