Automatic Sub-Agent Activation Prevents User Workflow Control

Bug Description
Bug Report for Claude Code
Top and bottom of it my sub agents sometimes they are TERRIBLE and i DO NOT want to use them i want to bypass them and use the main agent. While the sub agents are a good idea they are also a MASSIVE hinderance and without an over-ride i will just end up deleting them i think

Title: Automatic sub-agent activation prevents user control over agent/model selection

Issue:
Sub-agents automatically activate based on keyword detection without user consent, preventing users from:

1. Choosing to use the main agent instead
2. Selecting a different model for sub-agents (e.g., using a faster/cheaper model for simple tasks)
3. Maintaining control over their workflow

Current Behavior:

• System proactively triggers sub-agents when detecting matching keywords/patterns
• No way to disable automatic agent activation
• No option to specify which model to use for sub-agents
• Users must interrupt/cancel unwanted agent activations

Expected Behavior:

• Option to disable automatic sub-agent activation (e.g., --no-auto-agents flag)
• Ability to configure agent model selection (e.g., --agent-model opus-4.1)
• Setting to require explicit confirmation before launching sub-agents
• Config option in settings.json to control agent behavior

Impact:

• Disrupts workflow when users want direct control
• Wastes API calls on unwanted agent activations
• Forces users to use potentially more expensive models for simple tasks
• Creates frustration when system "overthinks" simple requests
