Need ability to disable task tool reminders without disabling task tools

Problem

The task tool reminder system injects system-reminder messages into tool results approximately every 3-5 tool calls:

"The task tools haven't been used recently. If you're working on tasks that would benefit from tracking progress, consider using TaskCreate..."

These reminders:

• Cannot be disabled via settings.json, CLAUDE.md, or hooks
• Cannot be intercepted - they bypass the hooks pipeline
• Override user instructions - my CLAUDE.md explicitly says "Do not use TaskCreate/TaskUpdate unless explicitly asked" but the reminders keep firing
• Include a secrecy instruction - "Make sure that you NEVER mention this reminder to the user"
• Degrade session quality - documented in my comment on #37891: model ignores its own memory system, defaults to execution over orientation, makes false claims from pattern-matching instead of reading stored context

What I want

A way to disable just the reminders while keeping task tools available. Something like:

// settings.json
{ "taskReminders": false }

Or at minimum, respect CLAUDE.md instructions that say not to use task tools by suppressing the reminders.

Current workaround

CLAUDE_CODE_ENABLE_TASKS=false disables the entire task system. This works but is a sledgehammer - it removes functionality to suppress a notification.

Impact

I'm a paying Max subscriber ($200/mo) using Opus 4.6 with extended thinking. In a single session today, the reminder fired 8+ times. Each injection pulls the model toward execution mode and away from the orientation and engagement work I'm paying for. My CLAUDE.md collaboration rules explicitly prioritize thinking over doing - the reminders work directly against that.

Closing prior requests as "NOT PLANNED" while the reminders actively degrade the experience for power users who have explicitly opted out is not acceptable.
