Sub-agent task broken in 2.4.22

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Was working in 2.4.21, but after update to 2.4.22 it is not able to access the Task tool to delegate sub-agent tasks.

Reverted back to 2.4.21 and is working again.

Steps to Reproduce

Steps to Reproduce

  1. Install Cursor 2.4.22 (or upgrade from 2.4.21 to 2.4.22).
  2. Ensure custom subagents exist in ~/.cursor/agents/ (e.g. plan-reviewer.md, code-reviewer.md) with valid YAML frontmatter.
  3. Start an agent conversation and ask it to use a subagent (e.g. “use the plan-reviewer subagent to review this plan” or “delegate to code-reviewer”).
  4. Observed in 2.4.22: Subagent is not invoked — either the Task tool is missing from the agent’s toolset, or invocation fails.
  5. Revert to 2.4.21: Subagent invocation works again.

Expected Behavior

Cursor agent delegating tasks to sub agents

Operating System

MacOS

Version Information

Cursor IDE 2.4.22

Hey, thanks for the report.

This is a known issue. A few users have reported the same thing:

The issue is that even when subagent_delegation_context is injected into the prompt, the Task tool itself doesn’t get attached to the agent. The team is aware, there’s no timeline yet, but your report helps with prioritization.

Workaround: roll back to 2.4.21 (like you already did). Subagents work there.

Can you share the Request ID from a chat where the Task tool didn’t show up? It’ll help the team debug this (you’ll need to temporarily disable Privacy Mode):

  • Cursor Settings CMD + Shift + J
  • Find “Privacy Mode” and turn it off
  • Create a new chat and reproduce the issue
  • Click the three dots in the top-right of the chat > Copy Request ID
  • Send it here

After that, you can turn Privacy Mode back on right away.

Why 2.5.0 still broken?

You guys fixed it before I had the chance to send the non-privacy enabled requests ^^

Cursor Works at the speed of Prompts <3
