Agent should execute tasks end-to-end without stalling on optional prompts

Problem

In real work, users assign a task and expect the agent to continue autonomously to completion.

However, the current behavior often stalls on optional phrases like:

• "if you'd like"
• "let me know"

This creates a stop-and-wait workflow and breaks the expected autonomous execution model.

Expected behavior

1. Action-first execution by default (analysis -> code changes -> verification -> delivery).
2. Ask users only when truly blocked by missing required input or risky irreversible action.
3. Avoid optional invitation tails that pause execution.
4. Keep progressing until the task is objectively complete.

Why this matters

For modern agent workflows, users should be able to assign a task, leave for an hour, and come back to a completed result instead of a stalled suggestion.

Context

This issue is about default interaction behavior and completion semantics, not model capability limits.
