Technical Verification Against `google/adk-python`

1. Installation & Extra Dependencies — ✅ Verified

Doc Claim: pip install "google-adk[slack]"
Code Verification:
- In pyproject.toml, optional-dependencies.slack is explicitly defined as [ "slack-bolt>=1.22" ].
- In slack_runner.py, missing slack_bolt explicitly instructs the user to run pip install "google-adk[slack]".

2. Module Imports & Exports — ✅ Verified

Doc Claim: from google.adk.integrations.slack import SlackRunner and from google.adk.agents import Agent
Code Verification:
- SlackRunner is re-exported at slack/init.py.
- Agent is exported as an alias for LlmAgent at agents/init.py.

3. Slack Scopes & Socket Mode Prerequisites — ✅ Verified

Doc Claim: Requires bot token scopes (app_mentions:read, chat:write, im:history) and app-level token scope (connections:write).
Code Verification:
- SlackRunner._setup_handlers listens for app_mention and message (specifically direct messages im and threads).
- SlackRunner._handle_message dispatches messages via say, chat_update, and chat_delete (requiring chat:write).
- SlackRunner.start uses AsyncSocketModeHandler, which requires connections:write.
- Matches the repository integration reference in README.md.

4. API Reference Table — ✅ Verified

Doc Claim: __init__(runner, slack_app) and start(app_token)
Code Verification:
- SlackRunner.init accepts runner: Runner and slack_app: AsyncApp.
- SlackRunner.start accepts app_token: str.

Issues & Recommended Fixes for PR #2035

Issue 1: Missing Import of `InMemorySessionService`

File & Line: docs/integrations/slack.md, line 63
Problem: The example code instantiates session_service=InMemorySessionService(), but InMemorySessionService is not imported in lines 45–50. Running this code throws NameError: name 'InMemorySessionService' is not defined.
Fix: Add from google.adk.sessions import InMemorySessionService to the top import block.
Code Reference: sessions/init.py and sample agent.py.

Issue 2: Missing `auto_create_session=True` on `Runner`

File & Line: docs/integrations/slack.md, lines 60–64
Problem: In SlackRunner._handle_message, session IDs are dynamically formatted per channel/thread (e.g. f"{channel_id}-{thread_ts}"). Runner.__init__ defaults auto_create_session=False (runners.py). Without auto_create_session=True, incoming messages will fail with a SessionNotFoundError.
Fix: Add auto_create_session=True when initializing Runner(...).
Code Reference: Sample agent.py.

Issue 3: Minor Comment Formatting

File & Line: docs/integrations/slack.md, line 59
Problem: #Wire it up to Slack over Socket Mode is missing a space after #.

+ADK provides the `SlackRunner` class to easily deploy your agents directly on Slack using [Socket Mode](https://api.slack.com/apis/connections/socket). This integration acts as an adapter that handles event listening, response dispatching, and automated conversation thread management.

Avoid using descriptors like "easily"; just the facts.
