I built an AI coworker that works while I sleep, using nothing but Claude Code

Description and use

An AI coworker built with Claude Code automatically watches Anthropic docs, summarizes changes, posts to Slack, and drafts articles when updates affect published material.

Problem

Need an automated watcher to detect changes in Anthropic’s official docs, summarize them, and draft articles without manual daily checks.

Outcome

Routine successfully detected no changes on first run, logged, and corrected Slack channel issue; second run posted summary and handled duplicate commit. Draft articles are generated for impactful changes.

Workflow

• Clone repo in routine
• Run git pull --rebase
• Execute watch.py to diff docs
• If no changes, log and send short Slack message
• If changes, read diffs, summarize per page, judge impact
• Write summary to log and post to Slack
• If significant change, draft article with front matter and placeholder for verification
• Commit, push, retry if needed

Evidence

The routine starts with your GitHub repository cloned. It cannot see your local files, local environment variables, or local services.

I used it to build a watcher that, every morning at 09:00 JST, reads 12 pages of Anthropic's official docs, diffs them against yesterday, posts a Japanese summary to Slack, and, when a change affects my books, pushes a draft article to GitHub.
