Add match chat to a Summer game: one World channel shared by everyone in the match. Hosted only.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /summer-world-chat — chat with everyone in the match ## Overview A **World channel** is a text channel for the World (match) the player has joined. Every player in that World can open the same channel by key, such as `"match"`. The platform owns everything that matters about it: - who may read it; - the text filter; - rate limits; - 24-hour retention; - blocks between players. Your game owns only the chat UI.

Always render it as plain text, never as markup | | Channel keys | 1–64 of `A-Z a-z 0-9 _ . -`, starting with a letter or digit; at most 64 channels per World | | History | Best effort, not a full log. A new handle shows the newest 2 messages; `load_older()` grows the window to at most 16 | | Lifetime | A handle belongs to one World admission. After leaving or joining another World, open a new one | | Not included | Direct messages (`summer-friends`), party chat (the Summer app) and messages written by your server | …

How to install
mdr add summerengine/summer/summer-world-chat@sha256:07f3254959e6d0feThe line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
