Two rounds later it scored 100. Here is every change that moved the number: Markdown content negotiation, a hand-rolled MCP server, RFC 9457 errors, RateLimit headers, an llms.txt that says when to use the site, and the one header Next.js would not let me set. - [Locum: Giving Grok Bot a Stand-In](https://www.harjotrana.com/blog/locum-grok-bot-provider-adapter) (22 Aug 2026, 20 min): Grok Bot can burn a week of quota in an hour.

Six releases in a day, including the one where the tool found five real bugs in its own code. - [The Practical Vercel Turborepo Cheatsheet](https://www.harjotrana.com/blog/turborepo-cheatsheet) (08 Dec 2025, 23 min): Task graphs, remote caching, and the pipeline config that actually keeps a monorepo fast.
