Glean lets you build, test, and publish its enterprise agents from Claude Code, Cursor, or Codex

Generally available as of Oct 21, the Glean plugin's /glean_run command writes an agent as a spec.yaml plus instructions.md in your repo, runs and evaluates it from the coding agent, then publishes it to Glean's managed runtime with its permissions across 275+ enterprise sources. Only Auto mode agents are supported; Workflow mode still needs Glean's visual builder (docs).
