Describe the bug and reproduction steps

Problem

When providing a detailed checklist in OpenHands PR comments, the system responds with overly brief summaries instead of addressing each item, forcing manual verification of completion.

Motivation

Currently, when users write "Here is a checklist of 50 things to do" and list them all, OpenHands responds with something like "I'm done. I did these 5 summarized things." This creates significant manual overhead as users must verify each original item against the brief summary.

Proposed Solution

OpenHands PR fulfillment comments should match the length and detail level of the original issue/request.

Why it's an easy win

This requires no complex new functionality - just ensuring OpenHands maintains the same level of detail in outputs as inputs. The source information is already available to the system, it just needs to mirror the structure and thoroughness of the original request.
