What it does

The button sits in the composer's trailing control seat — immediately before the model selector, exactly where Work Buddy puts it — and does one thing: it rewrites the draft you are looking at into a more effective prompt.

• Uses the conversation's own model. No separate model picker, no hidden default. The Host reads the Session's durable modelSelection projection first, then the selection the Client reports from its model seat, then the profile default. Whichever it lands on is the model you were already using.
• Four styles, right-click to change, remembered across reloads: Balanced (default), Concise, Detailed, Code-oriented.
• A fidelity guard, always on. Every concrete fact in the original — numbers, versions, paths, URLs, quoted strings, code identifiers — must survive verbatim, and the rewrite may not inflate past the style's budget. A failed check triggers exactly one corrective retry; the guard is a gate, not a loop.
• Conversation context, always on. The last few turns are read from the Session log so the rewrite knows what "it" refers to. Nothing is uploaded anywhere else; the call goes through the llm service you already configured.
• Revert is one click. After a rewrite the button becomes a revert arrow, so the original text stays one click away. Editing the result drops that backup, because there is nothing left to revert to.

Behaviour details

State	What you see
Draft empty, nothing rewritten	Button hidden (same as Work Buddy)
Draft has text	Spark icon; hover shows the tooltip and current style
Rewrite running	Spinner; a second click cancels and restores the draft
Rewrite succeeded	Revert arrow; click restores the original
Rewrite failed	Draft untouched; the reason appears in the tooltip
adjudicating / submitting phase	Button disabled

The style menu also opens with Shift+F10 or the context-menu key, and closes on outside press, Esc, or window blur.

Install

Install straight from GitHub — one command, nothing to clone:

dsh plugin add github:CTX666666/dsh-prompt-polish

Or clone the entire repository, including all subdirectories, and install that directory:

git clone https://github.com/CTX666666/dsh-prompt-polish.git
dsh plugin --profile <your-profile> add /path/to/dsh-prompt-polish

Quote Windows paths containing spaces. GitHub's complete ZIP also works after extraction; downloading only the root files does not produce a usable plugin.

Either way the bundle declares its own dsh.bundle.patch, so installing it inserts the Host row and the Client bundle in one step; no separate registration.

After installing, the button appears the next time the composer renders. No rebuild and no extra dependency are needed — see below.

Requirements

• DeepSeek Harness with a composer that exposes conversation.input.right and the llm + webServer services.
• The Client bundle injects @deepseek-ai/dsh-client-ui-conversation and @deepseek-ai/dsh-client-locale, so the locale and conversation packages must be present (they ship with the standard Web/Desktop profile).

Why there is no build step

Both halves are shipped as plain JavaScript, and that is deliberate:

• the Host half is src/index.js, an ES module that exports inject and apply. It imports nothing from the Harness packages — a workspace-installed bundle resolves its own bare imports against the workspace rather than the running installation, so the small request vocabulary it needs is built from the plain shapes the llm service documents.
• the Client half is src/client.js, a classic script that registers itself with window.__ModuleLoader__.load({ id, factory }) and resolves react through the loader's module table.

There is no bundler, no transpiler, and nothing to run before installing. What you read in src/ is exactly what loads.

Dependencies

Zero runtime dependencies. The Client half requires react, which the Harness loader already provides; the Host half requires nothing at all.

Replication spec

docs/IMPLEMENTATION.md is the build-it-again document: the behaviour contract, the verbatim system and user prompts, the four style directives, the context block format, the fidelity-guard regexes, the model fallback chain, fifteen edge cases, and a fourteen-item self-test. It is written so another engineer — or another model — can reproduce this plugin on a different host without reading src/ first.

If you only want the prompt text to reuse in a single-turn tool, jump to §11 of that document.

Verify

npm run check

Checks syntax and manifest wiring, then runs 27 HTTP and component-state regression tests. No npm install required. Running node scripts/check.mjs alone only checks syntax and package files. Tests use controlled model outputs; they do not establish end-to-end acceptance in a live Harness/model service.

How it calls the model

1. POST /dsh-prompt-polish/polish with { text, style, sessionId?, provider?, model?, reasoningEffort? }.
2. The Host picks a route (§ What it does), building the system prompt, the user prompt, the style directive, and the recent-context block.
3. One ctx.llm.stream() call at temperature: 1. Only text-delta chunks are accumulated; a finish with kind: 'error' | 'aborted' is surfaced as a failure.
4. The result is cleaned (one fenced block or surrounding quotes are stripped), then run through the fidelity guard. A failure retries once with an explicit correction note naming the missing tokens and the length limit.
5. The response is { ok: true, text, provider, model, style, fidelity, contextUsed }, or { ok: false, code, error } with code one of empty_input, no_model, llm_error, aborted, empty_result, fidelity_failed, invalid_request, not_found, method_not_allowed, internal. A failed corrective retry preserves the original draft and never returns rejected replacement text.

Editing the draft, navigating to another session or submitting invalidates an in-flight result. Cancelling disconnects the Host request and aborts upstream generation; the initial call and corrective retry share a 60-second deadline.

Only text-delta and finish are read, so a provider that streams reasoning blocks costs nothing extra.

Privacy

• The draft, the recent-context block, and the rewrite all travel to the llm provider you configured — that is the model call.
• Nothing is sent anywhere else. There is no telemetry, no analytics, no remote endpoint of this plugin's own.
• The chosen style is the only thing persisted, and it lives in the browser's localStorage under dsh-prompt-polish.style.
• No credential is stored, read, or forwarded by this plugin.

Compatibility

The Client half targets the slot contract declared by @deepseek-ai/dsh-client-ui-conversation. If a future Harness moves that slot, the button stops appearing rather than breaking the composer — the registration is wrapped in ctx.effect, so it is disposed cleanly on unload.

Contributing

See CONTRIBUTING.md. npm run check must pass, and behaviour changes need a sentence in CHANGELOG.md.

Repository

git clone https://github.com/CTX666666/dsh-prompt-polish.git

The manifest already points at this repository. Installation requires cloning and installing the directory; users do not need to initialize or push a repository.

package.json keeps "private": true on purpose: this plugin is distributed as a directory (or a git URL) that a DSH profile installs, not as a package on the npm registry. That flag prevents an accidental npm publish; it does not restrict cloning, forking, or installing.
