What we are seeing
Glean announced the capability in a post updated October 21. A Glean plugin creates an agent as a spec.yaml configuration file and an instructions.md behavior file that can live alongside code. Builders add skills or subagents, run the agent on sample inputs, run evaluations and review changes through Git pull requests with rollback. Published agents run on Glean's managed runtime with its knowledge graph, permissions across more than 275 enterprise sources and audit trail, and admins can manage or disable them in the Glean console. It is generally available for auto mode agents, while workflow mode agents still use Glean's visual builder. Pricing is not stated.
