dsh-sightline: DeepSeek Harness Instruction Source Comparison Tool

dsh-sightline is a plugin for DeepSeek Harness designed to address potential inconsistencies among coding agents (such as DSH, Codex, and Claude Code) when processing repository instructions. The plugin parses and compares each agent's instruction view using deterministic rules, generating visual reports that help developers investigate surface-level instruction inconsistencies. As a local, read-only tool, it does not modify files, supports specific versions of DSH, Node, and pnpm, and is open source under the MIT license.
