 Adding a custom analyzer is straightforward:

 3. Add your analyzer to the UI order:
+
    - Edit `aperisolve/static/js/aperisolve.js` and append `myanalyzer` to `TOOL_ORDER` so it appears in the frontend.
 
 4. Test locally: run the worker and submit jobs to ensure outputs are produced and displayed.
 
 > [!TIP]
+>
 > - Keep analyzers idempotent and write outputs to the provided `results_dir`.
 > - Return structured JSON so the frontend can render links/downloads automatically.
