Fixing OpenClaw's Blind Spots: Building a Sitemap to Fetch All Anthropic Blogs

A reader noticed that OpenClaw's summary of Anthropic's tech blogs was missing some posts — specifically one from April 8th. The root cause: Anthropic hosts their blogs at multiple distinct URLs, and OpenClaw's browser tool doesn't crawl all of them. The fix involved generating a sitemap by having the agent click every link to build a complete list, then feeding that sitemap into the summarization pipeline. The solution is packaged as a skill for easy reuse, though it does cost extra tokens to generate the sitemap due to the link-clicking process.
Key Takeaway
- Anthropic's blog URLs are not unified — they spread content across different hostnames, making naive scraping incomplete.
- OpenClaw's browser tool for RSS/blog aggregation doesn't auto-discover all pages; it needs a complete URL list upfront.
- Manually generating a sitemap by traversing all links works, but it consumes tokens proportional to the site's size.
This is a pragmatic workaround rather than a deep fix, but it's a useful pattern for any site with fragmented content. If you need reliable coverage of multiple-blog-host setups, pre-seeding with a sitemap is the simplest approach.
