Devlog — Slack Echo-Bot (Short report, 2026-06-02)

Status: Minimal prototype created and prepared for local run.
Goal: Simple Python echo bot that responds to messages and @-mentions via Socket Mode.
What I did: Created and updated:
Code: app.py — main logic using slack_bolt and SocketModeHandler.
Dependencies: requirements.txt (slack_bolt, python-dotenv).
Env example: .env.example (placeholders for SLACK_BOT_TOKEN and SLACK_APP_TOKEN).
Docs: README.md updated with quickstart.
Key design choices:
Language: Python.
Use Socket Mode to simplify local development without external HTTP endpoints.
Echo behavior: handles message events (ignores bot subtypes) and app_mention.
