Thanks Benno, we'll pick up these points in the next version.

Reviewer: Benno Overeinder Review result: Ready with Nits Intdir Review draft-ietf-anima-asa-guidelines-05 I am an assigned INT directorate reviewer for draft-ietf-anima-asa-guidelines-05. These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/. The document is intended as a document with an "Informational" status and proposes guidelines for the design of Autonomic Service Agents for autonomous networks. It is complementary to the documents describing the Autonomous Network Infrastructure described in RFC 8993 (and other related RFCs 8990 and 8994). The guidelines assist in the design and implementation of ASAs by describing the life cycle and behaviour (methods) in the different phases required to work correctly in the ANI. Overall, I find the document well written and understandable. It seems very thorough and well structured. And while the document references related RFCs and provides further information, it is perfectly legible as a standalone document. The document discusses functions to be implemented or be in place, but sometimes also discusses detailed implementation suggestions such as (increasing) multiple threads, queues, and locks. In this perspective, it is not only about guidelines in the design of ASA, but also about the implementation. These lower level implementation guidelines only appear in some places and do not interfere with the focus or understanding of the document. Small nit, the following sentence is not entirely clear to me (Section 5, last paragraph): It is expected that the value field of many objectives will be extended in service, to add additional information. The robustness principle (Section 8) is important for building trust in autonomous systems. Together with Section 9, Security Considerations, these are not afterthoughts, but essential sections on requirements and considerations for the design of ASAs. Perhaps the authors could also mention (reference) this earlier in the document, e.g. in the Introduction section.
