Custom Agents Don't Work

Summary

I use custom agents heavily in 4 other tools; they dont work in CMD. This includes:

• Can't invoke a specific agent in prompt
• One agent can't automatically invoke another agent
• Handoffs don't work between agents if orchestration is required

Expected Behavior

1. Ability to invoke orchestrator/master agent
2. The master agent identifies intent and delegates sub agents for research with an observable Delegation Prompt
3. The master agent reads the context returned by subagent

Actual Behavior

Steps to reproduce the issue

Reproduction:
While I can't share my custom agents, the speckit framework remains the easiest way to reproduce the issue. It is available with almost all coding tools https://github.com/github/spec-kit. It takes hardly 5 mins to reproduce; install speckit, and try to run the speckit commands /specify, /plan /analyze.

Command Code Version

0.26.7

Operating System

macOS

Terminal/IDE

vscode

Shell

bash

Additional context

No response

Start by reproducing the issue in VS Code with the speckit framework and the /specify, /plan, and /analyze commands. Compare custom-agent invocation, delegation prompts, handoffs, and returned context; done means the orchestrator can delegate to subagents and consume their context as described.
