Institute for AI Policy and Strategy — publication: AI Agent Governance: A Field Guide (April 2025) — 63-page playbook for governing AI agents, five-part taxonomy of interventions

Note: The source text confirms the publication title, author, and approximate publication date (April 2025). However, the source excerpt does not mention the page count (63 pages), does not describe it as a 'playbook', and does not reference a 'five-part taxonomy of interventions.' The source does mention 'a new framework for understanding agent governance solutions' but does not specify it as a five-part taxonomy. Since multiple specific claims (page count, playbook designation, taxonomy structure) are unverifiable from the provided source text, this is a partial confirmation rather than full confirmation.
