[blog] Agent of the Day – 2026-09-08

[github-actions]

Summary

Adds today's Agent of the Day blog post, featuring CLI Version Checker — a daily scheduled workflow that monitors 8 CLI/MCP tools and 8 Docker images for version or digest drift, opening a PR only when something actually changed.

Why this workflow

• Not previously featured in the Agent of the Day series.
• Real, recent evidence available: 5 scheduled runs in the last several days (3 success, 2 failure), with clear audit data.
• Demonstrates a disciplined "quiet by default" agent pattern: cache-first checks, parallel version fetching, and a strict noop-if-nothing-changed rule.
• Audit data surfaced a concrete, useful finding (a blocked firewall domain, ab.chatgpt.com:443) that ties into gh-aw's built-in observability story.

Evidence used

• Run logs: #552 (Sep 8), Sep 7, Sep 6, plus two failed runs on Sep 4–5 referenced for balance.
• agenticworkflows audit output for the above runs (key findings, network/firewall analysis, token/AIC metrics).
• Workflow source: .github/workflows/cli-version-checker.md.

File added

• docs/src/content/docs/blog/2026-09-08-agent-of-the-day.md
