Feat/short movie agents agent starter pack

[maeve2024]

Agent Starter Pack:

pyproject.toml

• Added [tool.agent-starter-pack] with example_question and [tool.agent-starter-pack.settings] (agent_directory = "app").
• Added agent-starter-pack>=0.14.1 to the dev dependency group.
• app/agent.py
• Added flexible auth block: set GOOGLE_CLOUD_PROJECT, GOOGLE_CLOUD_LOCATION, and GOOGLE_GENAI_USE_VERTEXAI from google.auth.default() so the agent works in ASP-generated projects.

README.md

• Added a “Recommended: Using Agent Starter Pack” section before Requirements.
• Primary flow: uvx agent-starter-pack create my-short-movie-agents -a adk@short-movie-agents.
• Alternative pip/venv flow in a collapsible section.

Build & lint:

pyproject.toml

• [project.optional-dependencies] with a lint extra (codespell, ruff, mypy) so make lint works.
• [tool.codespell] with ignore-words-list = "rouge" to avoid false positives.

uv.lock

• Regenerated with uv lock (includes agent-starter-pack and its dependencies).

Lint/type fixes:

app/story_agent.py

• type: ignore[no-redef] on the fallback from adk.agents import Agent to satisfy mypy with the try/except import.

app/storyboard_agent.py

• Only include images with a non-None _gcs_uri in the returned list so the result type is consistent.

app/video_agent.py

• Guard on operation.result and use result.generated_videos or []; in the list comp, only include items where video.video and video.video.uri are set.

app/utils/gcs.py and app/utils/tracing.py

• type: ignore[attr-defined] on from google.cloud import storage where mypy cannot resolve the storage attribute.

Testing:

• Integration tests pass in an ASP-generated project; agent manually tested in ADK web UI (make playground).

Reverting: I was only supposed to approve the workflow runs, not the PR itself.

where is this change from? what is the uri variable? this smells like hallucination which wouldn't work

Why not a copy/paste from the other PRs so they all share the same heading?
