 ### Fixes
 
+- Agents/subagents: enforce `subagents.allowAgents` for explicit same-agent `sessions_spawn(agentId=...)` calls instead of auto-allowing requester self-targets. Fixes #72827. Thanks @oiGaDio.
 - ACP/sessions_spawn: let explicit `sessions_spawn(runtime="acp")` bootstrap turns run while `acp.dispatch.enabled=false` still blocks automatic ACP thread dispatch. Fixes #63591. Thanks @moeedahmed.
 - Google Meet: route local Chrome joins through OpenClaw browser control instead of raw default Chrome, so agents use the configured OpenClaw browser profile when opening Meet.
 - Plugins/discovery: follow symlinked plugin directories in global and workspace plugin roots while keeping broken links ignored and existing package safety checks in place. Fixes #36754; carries forward #72695 and #63206. Thanks @Quackstro, @ming1523, and @xsfX20.

+- `subagents.allowAgents`: allowlist of agent ids for explicit `sessions_spawn.agentId` targets (`["*"]` = any; default: same agent only). Include the requester id when self-targeted `agentId` calls should be allowed.
 - Sandbox inheritance guard: if the requester session is sandboxed, `sessions_spawn` rejects targets that would run unsandboxed.
 - `subagents.requireAgentId`: when true, block `sessions_spawn` calls that omit `agentId` (forces explicit profile selection; default: false).
