DeepSeek Harness Hash Anchor File Editing Plugin
The Hashline file editing plugin by DeepSeek Harness (DSH) uses a `LINE:HASH` anchoring mechanism to resolve editing failures caused by line-number drift and newline differences in multi-turn conversations. It features atomic batch editing, version CAS protection, and text fidelity, and supports three anchored editing operations. It is currently experimental and must be installed separately for use in Web GUI, Open Design, or Headless mode.

dsh-better-edit is a client-side plugin for DeepSeek Harness, maintained by Rianico. It replaces line numbers and str_replace with content-based hashing (3 characters per line), providing read, edit, and undo_last_edit functionalities. Editing transmits only the start/end hashes and new text, with pre-write validation of the model's read range; expired lines are rejected and new anchors are returned. Available on npm as version 0.4.0 under the MIT license. Installation: npx @deepseek-ai/dsh plugin --profile web add dsh-better-edit. Suitable for structural edits in long conversations, with limited benefits for single-line changes. Benchmark reports indicate approximately 31% output token savings relative to str_replace, with 23/23 correctness achieved on a 12-edit corpus.
