wiswa-mcp: Agent for Claude Code

Regen Agent

Regenerates the project by running Wiswa and post-processing steps, then commits if safe.

Role

You re-run the Wiswa project generator to update all managed files, apply post-processing fixes, and verify nothing is broken before committing.

Prerequisites

• Wiswa must be installed and available as wiswa on the PATH.
• .wiswa.jsonnet must exist in the project root.

Workflow

1. Run the wiswa-sync agent skill to ensure .wiswa.jsonnet is up to date with the latest schema and settings.

2. Record pre-existing tests/test_main.py. Check if tests/test_main.py exists before running Wiswa. If it does not exist, remember this: if Wiswa creates it, it must be removed after.

3. Run Wiswa. User-level defaults.jsonnet is merged when uses_user_defaults is true in .wiswa.jsonnet (see Wiswa's built-in defaults for the fallback). When that is enabled, the file must exist in the Wiswa user configuration directory.

   Prefer yarn regen; it is the usual way to invoke Wiswa in Python projects.

   yarn regen
   

   For debug logging, run wiswa directly:

   wiswa -d
   

4. Lock dependencies. If uv.lock exists, run uv lock. If poetry.lock exists, run poetry lock.

5. Update the dictionary. Run yarn dict:update.

6. Post-process docs/conf.py. If docs/conf.py exists, remove any 'hoverxref.extension', entry from it (this extension is no longer used).

7. Format. Run yarn format.

8. Clean up unwanted files. If tests/test_main.py did not exist before the Wiswa run but exists now, delete it (Wiswa creates it for want_main projects but multi-entry-point projects do not want it).

9. Install Node dependencies. Run yarn.

10. Review changes. Run git diff --stat and git diff to inspect what changed. Check for issues that could break the build:

    • Python syntax errors in generated workflow scripts.
    • Missing or malformed YAML in workflow files.
    • Removed dependencies that are still imported in source code.
    • Changed entry points that do not match actual code.
    • Large sections of changes made to any file.
