DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

   For security reasons, plugin subagents don't support the `hooks`, `mcpServers`, or `permissionMode` frontmatter fields. These fields are ignored when loading agents from a plugin. If you need them, copy the agent file into `.claude/agents/` or `~/.claude/agents/`. You can also add rules to [`permissions.allow`](/docs/en/settings-reference#permissions-allow) in `settings.json` or `settings.local.json`, but these rules apply to the entire session, not only the plugin subagent.
 </Note>
 
-Subagent definitions from any of these scopes are also available to [agent teams](/docs/en/agent-teams#use-subagent-definitions-for-teammates): when spawning a teammate, you can reference a subagent type and the teammate uses its `tools` and `model`, with the definition's body appended to the teammate's system prompt as additional instructions. See [agent teams](/docs/en/agent-teams#use-subagent-definitions-for-teammates) for which frontmatter fields apply on that path.
+Subagent definitions from any of these scopes are also available to [agent teams](/docs/en/agent-teams#use-subagent-definitions-for-teammates): when spawning a teammate, you can reference a subagent type, and Claude Code applies parts of that definition to the teammate. See [agent teams](/docs/en/agent-teams#use-subagent-definitions-for-teammates) for which parts apply in each display mode.
