Session Metadata Migration Skill
Migrate code that talks to or implements the Agent Host Protocol to the flattened SessionState model. Use when asked to upgrade an AHP client/server/binding and you see a summary sub-object on SessionState (e.g. state.summary.title, session.summary.modifiedAt), model / agent on SessionState / SessionSummary / ChatState Published by microsoft in agent-host-protocol.

Skill instructions
AHP Session-Metadata Migration This skill helps you migrate a codebase that consumes (or implements) the Agent Host Protocol to the flattened SessionState model. The change moves all session metadata directly onto SessionState, makes SessionSummary a root-channel-only catalog type, relocates model/agent selection onto each Message (with a new per-chat draft), switches the summary timestamps to ISO-8601 strings, and removes the session/modelChanged / session/agentChanged actions. It is a single breaking step; there is no transitional version. If you are also coming from the pre-channels protocol, run the ahp-channels-migration skill first — this skill assumes you are already on the channel-based model. The migration is mechanical but touches several shapes at once, so do it in passes rather than file-by-file. The order below minimises the chance of leaving the codebase half-broken. After each pass, run your typecheck/test loop. How to use this skill 1. Read the Mental model section so y
