No docs are generated for `google.adk.cli` module for Python API Reference

[olliefr]

🔴 Required Information

Describe the Bug:

ADK docs include code examples that make use of get_fast_api_app from google.adk.cli.fast_api module: one such docs page.

Oddly enough, the Python API Reference has no documentation generated for google.adk.cli as of now: api reference for google.adk.cli

This is odd, because the module actually does have docstrings: module source file

Steps to Reproduce:

Search the API Reference for get_fast_api_app. Nothing found.

OR

Open the API Reference and select google.adk.cli on the navbar. There is no docs there.

Expected Behavior:

The docstrings are in the source code so I would expect the API Reference to pick that up when the docs are generated.

Observed Behavior:

As explained in the steps to reproduce section.

Environment Details:

• ADK Library Version (pip show google-adk): N/A
• Desktop OS: N/A
• Python Version (python -V): N/A

Model Information:

• Are you using LiteLLM: N/A
• Which model is being used: N/A

🟡 Optional Information

Regression:
Did this work in a previous version of ADK? If so, which one?

I don't know.

How often has this issue occurred?:

• Always (100%)

@olliefr Thanks for reporting!
The API docs are missing because the module google.adk.cli.fast_api is not currently included in the documentation build. The docs generator only documents modules that are explicitly referenced, even if they contain docstrings.
A simple fix is to add the module to the API documentation

.. automodule:: google.adk.cli.fast_api
   :members:
   :undoc-members:
   :show-inheritance:

After rebuilding the docs, the API Reference should correctly include get_fast_api_app and the rest of the module.
Thank you.
