Safe AI characters in published games: no keys in the build, replies via Summer's player AI gateway, moderation, spend caps, offline brain and a report button.
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
# AI Characters in Games ## Overview A talking flower, a shopkeeper who answers questions, a companion who reacts to what the player says. Players, often children, type or speak to it and it answers in character. **Core principle:** the game never talks to an AI provider. It asks Summer, as the signed-in player, for a reply from a persona the developer declared. Summer holds the keys (you never bring your own), moderates both directions, charges the cost to the developer's Summer credits and can switch the feature off per game. The game treats every AI answer as optional flavour on top of an offline brain that always works. **Status: preview.** `Summer.client.ai` ships with an upcoming Summer Engine release. The example checks for it at runtime and reads the `capabilities` of `status()` before using a call, and uses the offline brain whenever either is missing, so a game written this way ships today and gains AI replies when the platform turns them on. ## When to use - A character, creature or object answers free-form player text or speech. - You are about to put a model name, a provider SDK or a key into a game project. Stop and use this instead. …

How to install
mdr add summerengine/summer/ai-characters-in-games@sha256:380a682920393094The line at the top of this page pins the label git:20261010.4ade947, 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.
