dsh-prompt-sharpen

Pre-send checkup for prompts in DeepSeek Harness (DSH).

Most "enhance prompt" buttons rewrite whatever you typed. This one reads it first: a zero-token lint in the composer tells you which of four things your draft is still missing, and one click fills exactly those gaps — no padding, no invented requirements. The original stays one click away.

What it checks

Gap	Looking for
Output format	result shape: structure, fields, length, table / code block
Constraints	what must hold, what must not be done
Acceptance criteria	how you will know it is done or correct
Context	the background, inputs or materials that make it executable

The lint is local, rule-based and free: it never calls a model. A red dot on the button appears only when a gap is found, and the tooltip names the gaps (缺：输出格式、验收标准). A draft shorter than 12 characters is not checked — at that size everything is missing and the answer is noise.

Directed, not generic

When you press the button, the gaps are passed to the model as a 【体检结果】 block:

• Missing items → fill those, and do not restate what is already written.
• All four present → strip redundancy and tighten wording, and add nothing.

The rewrite replaces the draft in place. The button turns into a revert arrow; one click restores the exact original text. A request that fails (bad route, timeout, empty completion) never touches your draft — the button just shows the reason.

Three ways in

Surface	What it does
Composer button (left of the model selector)	check the draft, then sharpen it in place
/sharpen <draft>	same pipeline from the command line
sharpen_prompt tool	lets the agent tighten a prompt the user is drafting
checkup_prompt tool	diagnose only — no model call, no tokens

HTTP, for the UI half: POST /api/prompt-sharpen/check and POST /api/prompt-sharpen/enhance, both taking { "draft": "…" } and restricted to loopback, same-origin requests.

Install

Desktop app: open Plugins, search dsh-prompt-sharpen, install, then restart — client bundles are composed at startup.

Command line, for a web profile:

dsh plugin --profile web add dsh-prompt-sharpen

The package declares dsh.bundle.patch and ships cordis.patch.yml, so it loads as a bundle without hand-editing the profile.

Configuration

- id: dsh-prompt-sharpen
  name: dsh-prompt-sharpen
  config:
    provider: deepseek-account   # default: the calling agent's route,
    model: deepseek-flash        #          then the composition default model
    maxOutputTokens: 1600
    timeoutMs: 45000
    maxInputChars: 8000
    uiButton: true               # false: keep the command and tools, drop the button

Notes

• Zero runtime dependencies. Both halves are plain ESM/CJS and only touch ctx services, so link: installs work too.
• The button never sends your message. You always read the result before pressing Enter.
• Only the draft you press the button on is sent, to the model route you configured. No telemetry, no storage.
• Client bundle lives at client.js; host half at index.js; both are small enough to read in one sitting.
