Potential duplicate found:

• PR fix(core): unify model-visible shell output previews #45109: fix(core): unify model-visible shell output previews
  • This PR appears to address the same concern about standardizing shell output previews for the model. It likely overlaps with PR fix(core): cap session shell output #45136's goal of capping session shell output to 50 KiB to match the regular shell output behavior.

Recommendation: Check if PR #45109 already implements the 50 KiB capping logic or if these PRs address complementary aspects of the same issue (#45099).
