dsh-session-prompt-optimizer

中文说明 · MIT · a plugin for DeepSeek Harness

One button in the composer. It takes the draft you have typed, rewrites it into a clearer instruction for the agent, and shows both versions side by side above the composer. Your text is only replaced when you say so.

Install

dsh plugin --profile web add github:markmuteki/dsh-session-prompt-optimizer

or from npm:

dsh plugin --profile web add dsh-session-prompt-optimizer

Restart dsh web after installing. No configuration is needed.

Use

Gesture	Result
Click	Rewrite the draft, close to its original length and shape
Shift+click	Structured rewrite: goal, then context and constraints, then the finished result
Alt+click	Compress: same intent, fewer words

The button sits left of the model chip. It is disabled while the composer is empty, while a message is being sent, and while a rewrite is already running.

A finished rewrite opens a card just above the composer with the draft on the left and an editable result on the right: Use this writes it into the composer, Copy leaves the composer alone, Dismiss closes the card. If you kept typing while the request was running, the card says so instead of overwriting the newer text.

What it keeps

• Every intent, fact, path, name, number, version and constraint already in the draft. It is not allowed to invent a requirement.
• The language of the draft: Chinese stays Chinese, English stays English.
• Code, commands, paths, URLs and quoted strings, copied verbatim.

It drops pleasantries and framing, leads with the task, and replaces vague verbs with the concrete action. A draft that is already a good prompt is left nearly alone.

It reads the session it rewrites for

A draft written into a running conversation is rarely self-contained. Each rewrite is given a bounded excerpt of the session: at most six recent messages (600 characters each, about 2,400 in total), the session title and active goal, and the workspace directory. The excerpt is only read — the plugin adds no messages to the session and persists nothing beyond its own template cache.

Cost and privacy

One extra model request per click, on the model the composer is set to, with reasoning effort pinned to its lowest level. The draft and that excerpt go to the same model that would receive the message itself. Nothing else is sent anywhere except the upstream release check described below (a plain HTTPS request to GitHub).

Where the instructions come from

The rewrite instructions are the user-optimize templates of the open-source prompt-optimizer project, not text written inside this plugin:

Mode	Template
Click	User prompt basic optimization
Shift+click	Step-by-step planning
Alt+click	Basic optimization plus a brevity rule
mode: "professional" (API only)	Professional optimization

A background check reads that project's latest release shortly after the harness starts and then every six hours, validates the six templates (Chinese and English) and caches them in .state/upstream.json. New templates are picked up on the next click; no restart and no install. Offline, the cached copy is used, falling back to the built-in prompt. GET /_prompt-optimizer/health reports the release being followed and POST /_prompt-optimizer/refresh forces a check.

Limits

• Accepting replaces the whole draft: inline reference chips become @path text.
• Slash commands are refused, since rewriting one would break it.
• Drafts longer than 12,000 characters are refused.
• One rewrite at a time per session.
• The host gives up after 45 seconds, the client after 90.
• Web platform only.

Development

File	Role
index.js	Host half: the three same-origin routes and the model call
client.js	Browser half: the button, the card, setDraft
context.js	Builds the bounded session excerpt
upstream.js	Fetches, validates and caches the upstream templates
docs/DETAIL.md	Longer notes on behaviour and design

node _prompt_check.mjs runs a local check of the prompt assembly.
