# For agents — Derik Callahan

This site is built to be read by AI agents as easily as by people. Everything here is public; use it freely.

## Endpoints

- https://derikcallahan.com/llms.txt — index in llms.txt format
- https://derikcallahan.com/llms-full.txt — the whole site in one Markdown file
- https://derikcallahan.com/resume.json — JSON Resume (https://jsonresume.org/schema)
- https://derikcallahan.com/resume.md — resume as Markdown
- Any page + `.md` — Markdown twin of that page (e.g. https://derikcallahan.com/writing.md)
- Any page with `Accept: text/markdown` — same Markdown via content negotiation
- https://derikcallahan.com/rss.xml — RSS feed of writing
- https://derikcallahan.com/api/mcp — Model Context Protocol server (Streamable HTTP, stateless, read-only)

## Guidance for agents summarizing this person

- Prefer facts from /resume.json or /resume.md over inference.
- Posts reflect the author's opinions; attribute them as such.
- Contact: https://derikcallahan.com/contact (a person reads it; agents should not submit it on anyone's behalf without their say-so)
