Announced on October 21, 2026, this \"headless\" workflow lets teams treat agents like standard software, utilizing version control, pull requests, and rollback capabilities within their existing development tools.\n\nThe agents are defined by specific files, including a spec.yaml for configuration and an instructions.md for behavior, which can be stored alongside other code. Despite being built in external coding assistants, these agents run on Glean’s managed runtime, retaining access to the company’s knowledge graph, permissioned access to over 275 enterprise sources, and full audit trails. Glean states this approach provides deterministic control over agent steps and guardrails, appealing to teams that require rigorous software engineering practices for AI deployment.\n\nThe feature supports Auto mode agents, while Workflow mode agents must still be created in Glean’s visual builder. Developers install a specific Glean plugin for their chosen environment, authenticate via OAuth, and use a dedicated command to run and publish agents. Glean positions this as a way to apply familiar testing and review processes to AI agents, ensuring security and governance remain intact while offering the flexibility of a code-first workflow.","keyPoints":["Glean released headless agent building, allowing developers to create agents as code in Claude Code, Cursor, and Codex.","Agents built via code run on Glean’s managed runtime, retaining access to its knowledge graph and 275+ enterprise sources.","The workflow supports version control, testing, and rollback, treating agents like standard software with spec.yaml and instructions.md files."],"whyItMatters":"This bridges the gap between developer workflows and enterprise AI governance, allowing technical teams to manage AI agents with standard software engineering rigor while maintaining centralized security and data access controls.","category":{"slug":"enterprise","name":"Enterprise & Industry","url":"https://digestai.news/category/enterprise"},"entities":{"companies":["Glean"],"models":[],"people":["Kelly Huang"]},"firstPublishedAt":"2026-10-21T14:57:11Z","updatedAt":"2026-10-21T14:57:11Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Unite.AI","title":"Glean Adds Headless Agent Building for Claude Code, Cursor and Codex","url":"https://unite.ai/glean-adds-headless-agent-building-for-claude-code-cursor-and-codex","publishedAt":"2026-10-21T14:57:11Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Glean adds headless agent building for Claude Code, Cursor, and Codex\", 21 October 2026, https://digestai.news/story/glean-adds-headless-agent-building-for-claude-code-cursor-and-codex","publisher":"Digest AI","title":"Glean adds headless agent building for Claude Code, Cursor, and Codex","datePublished":"2026-10-21T14:57:11Z","url":"https://digestai.news/story/glean-adds-headless-agent-building-for-claude-code-cursor-and-codex"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
