Delegated agents inherit profile tool and MCP limits from SDK v1.51.0. A profile restricted to selected tools or MCP servers could delegate to a child with more authority. The resolver now supplies SubAgentScope to delegation tools; offered definitions are filtered, the built child is checked, constraints propagate through nested task/workflow delegation, and uncheckable agent kinds are rejected when constrained. This is an authority repair in released source, separate from secret filtering and the local-terminal key alias.

Channel: tagged-release. Half: defect. Date: 2026-10-03 (SDK v1.51.0); 2026-10-06 (Canvas v1.25.0 bundle).

Operator consequence: Upgrade a server that delegates constrained profiles to SDK/agent-server 1.51.0 or later; Canvas first includes the fix at v1.25.0. Expect incompatible children to disappear or fail instead of silently gaining authority. A live test should attempt an extra-tool child, an extra-MCP child and nested delegation; do not infer secret containment from this tool/MCP repair.
