du-u-uck/DSH-Prompt-Optimization

DeepSeek Harness web plugin that adds a prompt optimization action beside the composer. The optimized draft replaces the current input and can be restored with one click. A dedicated optimizer model can be selected in Settings → Prompt Optimization.

Features

• One-click optimization — sends the current draft through a one-off host-side model request and writes the result back to the composer.
• Undo — restores the original draft for the current session.
• Default model — uses the current session model when no optimizer model is configured, otherwise falls back to the deployment default.
• Prompt Optimization settings — lists the same providers and models available in Settings → Models.

Architecture

• Host half: lib/index.js
• Browser client: lib/client.js
• Bundle manifest: cordis.patch.yml

Limits

• Replacing the draft loses reference chips such as @file; undo restores the saved text draft.
• Optimization rewrites wording but does not add requirements that were not present in the draft.
• Requests are capped at 256 KB input, 4096 output tokens, and a 120-second timeout.
