dsh-prompt-optimize

DeepSeek Harness web plugin: rewrite the current composer draft through an auxiliary LLM call. Click replaces the draft only; it never sends a message or starts a turn.

Install

dsh plugin --profile web add github:peterliucius/dsh-prompt-optimize

Git-hosted plugins build on install through prepare. pnpm ≥10 blocks that script until you allow it. The first add fails and prints the key; copy it into the profile's pnpm-workspace.yaml:

allowBuilds:
  dsh-prompt-optimize: true

Then re-run the same add. Only allow packages whose source you trust. Pin a commit (github:peterliucius/dsh-prompt-optimize#<sha>) if you do not want a later push to change what runs.

A local checkout that already has lib/ does not need allowBuilds:

dsh plugin --profile web add /path/to/dsh-prompt-optimize

Start the web profile:

dsh --profile web

The patch inserts one row named dsh-prompt-optimize (maxInputBytes: 32768, maxOutputTokens: 4096, timeoutMs: 60000). The same package's dsh.client declaration occupies conversation.input.right. Default web-app does not mount this plugin.

Behavior

The sparkle button is always visible. It disables when the draft is empty after trim, contains a composer reference chip (U+FFFC), the session is removed, or the input machine is not in the plain phase.

Click captures the current draft, calls ctx.promptOptimize.optimize over the promptOptimize Typert Remote, and overwrites the composer through inputActions.setDraft only when the live draft still equals that capture. Failures toast; a moved draft toasts and is not replaced.

The auxiliary request frames the draft as JSON, uses a fixed rewrite instruction, enforces the configured byte and token budgets, composes timeout with caller cancellation, and sets reasoningEffort: 'off'. It never enqueues a user message or appends a durable session event.

Route resolution uses plugin provider/model when both are set, else the session's latest request/header config, else ctx.get('agentDefaultModel')?.currentSelection().

Configuration

Every field is required except the paired route override; there are no library defaults. The bundle row supplies the values below.

Key	Contract
maxInputBytes	Positive UTF-8 byte ceiling for the final JSON-framed user prompt.
maxOutputTokens	Positive auxiliary generation token cap.
timeoutMs	Positive end-to-end deadline within the runtime timer limit.
provider, model	Optional explicit route; both or neither.

Override them in the profile's cordis.patch.yml by restating the whole row config.

Develop against a local harness

Tests resolve @deepseek-ai/dsh-* peers through a sibling deepseek-harness checkout at ../dsharness. Without that checkout, pnpm test skips.

pnpm install
pnpm test
pnpm build

Regenerate Typert host + remote-client artifacts after changing @Remote methods (requires the sibling checkout):

pnpm exec tsx scripts/generate-typert.ts
