dsh-prompt-optimizer

A prompt optimizer for the conversation input tool row: pick a category (Basic / Context / Image) and a template, then the optimize button rewrites the draft in place, with cancel, elapsed time, token usage and one-click undo. Ships 15 templates — task-instruction rewriting with hard result-side constraints, step planning, safety-research framing for reverse-engineering requests, system-prompt role cards, and text-to-image / image-to-image prompt rewriting. Context templates read the last turns of the current session for coreference resolution. The host half registers two loopback-only routes and calls the harness model service instead of any API directly; a settings section exposes nine fields (provider and model override, reasoning effort, temperature, output-token cap, timeout, input-length and context budgets). Output guards check that user-written constraints survive and that no new method-side constraints are invented, and warn rather than auto-retry. Adapted for dsh 0.2.0-rc.2.
