An internal agent type for running workflow scripts

Under the hood
Useful2 Signal3
Subagents

An internal workflow-subagent runs workflow scripts and isn't selectable by you.

What

A built-in agent definition named workflow-subagent is described as an internal subagent for workflow script orchestration. It is granted all tools with a specific deny list, and it is not offered as something you can pick; workflow execution uses it directly.

Details
  • The environment variable CLAUDE_CODE_DISABLE_WORKFLOWS exists in this build, but nothing observed ties it to this agent definition, so whether disabling workflows also removes this agent is not settled by the code.
Evidence

Internal subagent for workflow script orchestration.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
