Environment variables.

Give your agents the tokens and settings their tools need — GH_TOKEN for gh, a database URL, a proxy — without putting them in a prompt. DayMug has two places for variables: yours, and the provider account's.

Your variables

1. Open Settings → Advanced → Environment variables. Every user has this page.
2. Write one VAR=VAL per line

   GH_TOKEN=ghp_…
   GITLAB_TOKEN=glpat-…
   HTTPS_PROXY=http://proxy.internal:3128

   Names start with a letter or _ and contain only letters, digits and _. Values may be empty or contain =. Blank lines are ignored; a malformed line is rejected when you save, with its line number.
3. Save environment — the next turn of every agent you own picks it up, in the browser, in IM and in scheduled tasks. A task already running keeps the old values.

The values apply to all your agents — agents have no variables of their own. Admins don't see them in the user list.

Provider account variables

Admins can set variables on each provider account (Settings → Administration → Providers & models → account → Environment variables). They reach every conversation on that account, for every user bound to it — the place for an endpoint's ANTHROPIC_BASE_URL or OPENAI_API_KEY (see Compatible endpoints).

Which value wins

Each agent process gets, in this order — a later layer overrides an earlier one:
