dsh-prompt-boost-pro

dsh-prompt-boost-pro — enhance the draft before you send it

English | 中文

A sparkle button in the DeepSeek Harness (DSH) composer tool row. Click it, pick a mode, and the model rewrites your draft into a better prompt — shown as an original-versus-enhanced preview that you accept, re-run in the other mode, or discard. Nothing touches your draft until you accept.

Inspired by Trae CN's "optimize input": type a rough idea, get a directly executable instruction. Unlike a one-shot rewrite, this plugin keeps you in control — you always see both versions first, and after accepting, the same button becomes an undo until you change or send the text.

Features

• Two modes, picked per use — Structured reorganises the draft for the task at hand (goal, constraints, expected output, acceptance), Light only disambiguates, fixes wording and tightens; both keep your intent and your language, and neither invents requirements you did not write.
• It never interrogates you. The prompt policy forbids handing back information the agent can look up itself (repo layout, stack, scope, previous conclusions). At most one [待补充: …] placeholder survives, and only for a decision that is genuinely yours.
• Comparison preview, never a silent overwrite — original and enhanced side by side; accept, re-run in the other mode, copy, or discard. If you edited the draft while the preview was open, it says so and makes the overwrite explicit.
• Undo that knows when it is over — after accepting, the button reads "undo" only while the draft still equals the enhanced text; sending or editing the draft returns it to normal instead of offering an undo that cannot work.
• Truncation is surfaced, not swallowed — output budget adapts to the draft (4000 → 8192 tokens) and a capped answer is still returned, flagged, with a hint instead of an error.
• Model route resolved four ways — plugin config → the model currently shown in the picker → the session's last request → the deployment default. A brand-new session works on the first click.
• Dismissals everywhere — click the icon again, click anywhere outside, or press Esc; the preview also closes with Esc. The button stays clickable while its menu is open, so the menu can never trap you.
• Bilingual UI (zh / en), theme-native (real DSH design tokens), no tracking, no config files written.

Requirements

• DSH web GUI (dsh web), harness 0.1.2-alpha.1 or newer; the current line (0.1.5-rc.x) is tested.
• Node ^22.19.0 || >=24.0.0 (the host half runs inside the harness process).
• A session whose model is routable — the default model counts, so no setup is needed.

Install

# from the profile that runs your web GUI (usually "web")
dsh plugin --profile web add github:xiaoshengliang2002/dsh-prompt-boost-pro

# or from a released tarball
dsh plugin --profile web add https://github.com/xiaoshengliang2002/dsh-prompt-boost-pro/releases/latest/download/dsh-prompt-boost-pro.tgz

# or from a local checkout (symlinked; rebuild shows up without reinstalling)
dsh plugin --profile web add link:/path/to/dsh-prompt-boost-pro

Then restart dsh web and reload the page. The lib/ bundles are committed, so installing from source needs no build step and no pnpm build approval.

Uninstall: dsh plugin --profile web remove dsh-prompt-boost-pro.

Where the button lives

+ | permission control | ✨ enhance | summon-expert entry | … | model | context meter | send

It registers conversation.input.left with order: -10, so it sits immediately after the permission control. Move it after the summon-expert entry by changing order to 20 in src/client/index.ts.

How it works

Wire contract, error codes and the prompt policy are documented in docs/design.md; the awesome-dsh-plugin checklist is in docs/awesome-dsh-plugin-checklist.md.

Development

The repository is a normal npm package; lib/ is build output that is committed on purpose (so source installs are build-free).

npm run typecheck      # tsc --noEmit, 0 errors
npm run build          # esbuild → lib/index.js + lib/client.js
npm test               # 4 offline suites: host 28, client 28, UI dismissal/undo 40, prompt policy 27
npm run release:pack   # sync docs + build + npm pack
npm run release:verify # unpack the tarball and assert 31 contract/listing conditions

No network is required: node scripts/link-dsh.mjs links the packages of a local DSH checkout into node_modules (esbuild, typescript, react, @types) so the build and tests run offline.

preview/index.html is a clickable preview of the composer UI built from DSH's real design tokens and this plugin's real stylesheet; preview/shot-preview.cjs renders the state screenshots into preview/shots/ (declared for the storefront via screenshots.json).

Version history

• 0.1.2 — reasoning-effort passthrough. The client sends the model picker's current reasoning effort (low/high/max) with each request and the host passes it to the LLM call; deployments can pin one via the new reasoningEffort config key. Fixes 400 {"code":"1210"} on models that always think (e.g. GLM-5.3-Flash), whose default effort is "off" and gets rejected by the upstream API.
• 0.1.1 — upgrade-window compatibility. The host registers the legacy POST /api/prompt-boost/enhance path alongside the current one, and the client falls back to it when the current path answers 404/405 — so a half-updated pair (page refreshed but server not restarted, or the reverse) keeps working instead of failing with "unexpected response (HTTP 404)".
• 0.1.0 — first release. Two enhancement modes (structured / light); original-versus-enhanced preview before applying; undo that expires with the draft; click-outside/Esc dismissal; adaptive output budget with a truncated flag instead of dropping a capped answer; four-level model route resolution so a brand-new session works on the first click; bilingual UI and a custom sparkle icon. 123 offline assertions plus 34 packaging checks. Wire path: POST /api/prompt-boost-pro/enhance; the button sits after the permission control.
