[FEATURE] Feature request: Pause & amend prompt during agentic execution

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

During long-running agentic tasks, there's no way to pause execution and append additional context or instructions. If you realize mid-execution that you left out important details, your only option is to stop the entire process and re-submit the full prompt from scratch — wasting time, tokens, and prior progress.

Proposed Solution

Add the ability to pause an ongoing agentic execution and inject additional instructions before resuming. This could work as:

A keyboard shortcut (e.g., Ctrl+P) to pause execution
A prompt appears to type additional context
Execution resumes with the amended context incorporated

Alternative Solutions

none. you have to Stop and type retype whole prompt

Priority

Medium - Would be very helpful

Performance and speed

Use Case Example

Complex prompts are hard to get 100% right upfront
Long-running tasks can burn significant tokens before you realize something's missing
Current stop-and-restart workflow loses all progress and context
