## Notes

- [Two agent auth specs, at once](https://benmcadams.info/notes/two-agent-auth-specs) — Two proposals for agent auth landed the same week — same name, same problem, different mechanisms. (markdown: https://benmcadams.info/notes/two-agent-auth-specs.md)
- [MCP is a toolbox. A2A is a coworker.](https://benmcadams.info/notes/mcp-toolbox-a2a-coworker) — MCP and A2A get lumped together, but they solve different problems. (markdown: https://benmcadams.info/notes/mcp-toolbox-a2a-coworker.md)
- [AI agents fetch pages differently](https://benmcadams.info/notes/agents-fetch-differently) — A 308 redirect broke ChatGPT's retrieval but not Claude's. Same URL, different behavior. (markdown: https://benmcadams.info/notes/agents-fetch-differently.md)
- [Two kinds of AI crawler](https://benmcadams.info/notes/two-kinds-of-ai-crawler) — The split between training-style crawlers and user-side fetchers changes how I read a traffic spike. (markdown: https://benmcadams.info/notes/two-kinds-of-ai-crawler.md)
- [Markdown mirrors](https://benmcadams.info/notes/markdown-mirrors) — Serving .md alongside HTML is cheap, and it makes agents parse your pages far more efficiently. (markdown: https://benmcadams.info/notes/markdown-mirrors.md)
- [Hello, world](https://benmcadams.info/notes/hello-world) — A small home for field notes on the things I'm learning. (markdown: https://benmcadams.info/notes/hello-world.md)
