Feature hasn't been suggested before.

  • I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Hashline is a new edit mode just introduced to the oh-my-pi agentic coding tool (a fork of Pi). In a lot of cases it speeds up edits and reduces rejected edits from diffs not matching. Having tested it out myself in oh-my-pi I really want to bring the feature over to OpenCode.

Thanks for the feature request! Before implementation, please check if this might relate to existing issues addressing similar edit tool challenges:

  • #12406: Proposes using checksums for file verification (similar solution to hashline)
  • #5840: Tracking issue for edit tool reliability, includes discussion of content-based hashing
  • #4406: Discusses the underlying need to re-read files between edits

These issues explore similar solutions to the 'rejected edits' problem that hashline addresses. Linking them might help the team prioritize and coordinate implementation.
