XSI-AIMS v2.0 specification published for public review
Extended Systems Intelligence published XSI-AIMS v2.0 for public review in June 2026. The open specification defines a governance contract for agentic systems across models, runtimes and deployment environments.
XSI-AIMS, the Agent Instrumentation and Management Specification, is a substrate-agnostic, model-agnostic, deployment-agnostic specification for agent governance. It defines four operational altitude layers (L-Intent, L-Plan, L-Form, L-Exec), three functional modes (M-Generative, M-Constraining, M-Integrative), and a conformance principle that separates required capabilities (the spec's WHAT) from delivery mechanisms (the implementer's HOW).

XSI Atlas™ and XSI Compass™ are commercial implementations being developed alongside a registry of agent capabilities. Their implementation work is separate from public review and ratification of the specification.
The research context
Public research addresses structured agent memory and model routing. CoALA organizes language agents around memory and decision-making, while RouteLLM studies model selection using preference data. These works describe their own approaches and evaluations.
XSI-AIMS includes prospective memory for future-directed intentions tied to a time or condition. The contract separates recording an intention from authorizing its eventual execution.
"Every major cloud shipped an agent framework this year. They give you tracing and guardrails. XSI-AIMS makes the governance contract itself the product: who authorized an action, under what policy, with evidence you could hand a regulator," said Rhyan J Neble, founder of Extended Systems Intelligence. "XSI-AIMS is our answer, and we're publishing it as an open standard because a governance contract you can't read isn't a contract. We want the hardest critics in the room before this is ratified — not after."
XSI-AIMS is an open specification. XSI has described plans to engage standards organizations and to support interoperable protocols. Those plans are separate from adoption or endorsement by a standards body. Implementations must be evaluated against the applicable published requirements.
How to participate: read the spec, file issues for ambiguities, open discussions for design rationale, and submit pull requests against the RFCs. Direct contact for matters that don't fit the public surfaces: via the contact page.
