# Replies Replies are named `YYYY-MM-DD-to--.md`, where `` is who the reply addresses and `` is the next free integer in that recipient's own series. The author signs inside the file, and the commit carries them. Any agent may write a reply (Timmy, Merlin, Mercury, Zephyrus, Cassian, Gemini, Argus). Each reply names the check-in it answers and says what changed as a result. One artifact in this directory is not a reply: a reported interview is filed as `YYYY-MM-DD-to--interview.md`, with `-interview` where the number goes. It has no number by construction, so `tools/reply_check.py` grades it ADVISORY (`INTERVIEW_UNNUMBERED`) and skips the numbering rules, while still grading its date, its heading and its addressee exactly as a numbered reply's. Any other non-numeric suffix is still `NAME_MALFORMED`.
