Summarize new articles and post to Slack

What to build: Summarize new articles for your team chat. Every hour, summarize new articles in your feed and post the summary to your team chat. This is for engineers. How it behaves: 1. Runs at the top of every hour. 2. Read the latest items from the feed. 3. If anything new since last run, then go to "Summarize with Claude", otherwise go to "Stay quiet". 4. Ask Claude for a short summary of the new items. 5. Post the summary to the team Slack channel. 6. Nothing new in the feed, so send nothing. The tools: - Anthropic (for "What should write the summary?"). I will need you to create the key ANTHROPIC_API_KEY (Anthropic API key). I add the values in Autoploy myself; you only need their names. - Slack (for "Where should the summary be posted?"). I will need you to create the key SLACK_BOT_TOKEN (Slack bot token), provide the setting SLACK_CHANNEL (Slack channel). I add the values in Autoploy myself; you only need their names. The platform: Connect to my Autoploy MCP server, call get_authoring_guide to read the authoring guide, and build the automation with the Autoploy SDK contract. Model every yes/no fork as a condition step with truthful labeled branches, keep every external side effect idempotent and keyed, and deploy it with deploy_automation. Before you build: Repeat the plan back to me in plain English and ask follow-up questions about anything unclear or ambiguous. Do not guess. Ask me for each key by name when it is time, and never ask me to paste a key anywhere except my own secure setup.
