Released 2026-06-28. Streams can now drive your workflows and agents from code, with in-editor help.

Call workflows & agents from stream code. A stream's Tools tab now has Workflows and Agents sections — add the workflows and streaming agents (from the same app) your stream code may invoke. Code runs them with ctx.workflows.run(id, input) (returns { run_id }) and ctx.agents.run(id, input) (returns { job_id }). Only the ones you list can be invoked — anything else is rejected, so a stream can't run up costs on assets you didn't allow.
Stream code cheat sheet. The Code tab has a new Cheat sheet button documenting the whole ctx API — the handler shape, ctx.streams.publish, ctx.ai.call, ctx.sheets, ctx.workflows/agents.run, and ctx.http.
Copyable Tools snippets. The Tools tab shows ready-to-paste code for whatever you've configured — ctx.ai.call once a model is picked, ctx.sheets once a database is linked, and ctx.workflows.run / ctx.agents.run for each workflow or agent you add.
