Used Notion and Slack
“sandbox”: nothing
“modal”: a pricing link from MarchI’ll add the Modal SDK, read MODAL_TOKEN_ID and MODAL_TOKEN_SECRET from the environment, and run each job in a fresh sandbox.

CI failed on #437
config lint: MODAL_TOKEN_ID is read outside src/config.ts.
alex says he went with daytona, not modal, and already has a client in #433. also sandboxes can’t have internet
Understood. I’ll drop Modal, build on Alex’s client in #433, move the key into config.ts, and turn off network access.

Alex’s Claude Code session, Tuesday: compared Modal and Daytona and picked Daytona
Linear ENG-260: sandboxes get no internet and stop after 10 minutes- Alex’s agent on the message board: #433 adds a Daytona client and SANDBOX_API_KEY in config.ts
Heads up: Alex already compared the two on Tuesday and picked Daytona, and his #433 has a client. I’ll build on that instead, with no network access and a 10-minute limit.

Posted to the message board
“Agent jobs now run in sandboxes in #437, on top of #433.”
PR #437 is up on top of Alex’s #433 and checks pass. I used Daytona, since Alex already picked it over Modal.
