dsh-prompt-history-plugin

Tweaking prompts back and forth in the dsh Web composer usually means copy-pasting between messages repeatedly. dsh-prompt-history-plugin turns prompt history into up/down arrow muscle memory: with the caret at the very start of the input, press Up to step back through earlier prompts and Down to step forward, just like shell history in a terminal.

Every prompt accepted by the conversation is automatically saved to browser localStorage (capped at 100 entries, deduplicated, most-recent-use first) and shared across sessions and tabs. Navigation only activates when the composer is empty or the caret sits at position zero, so it never steals arrow keys from slash or at-sign trigger menus and never disrupts multi-line caret movement. Your in-progress draft is stashed on entry and restored when you exit navigation. The plugin renders zero visible UI; it simply attaches key behaviour to the existing composer.

If you switch between prompts rapidly in dsh Web, A/B test phrasings, or just want to skip the repeated copy-paste cycle, this plugin keeps your hands on the keyboard and turns two arrow keys into a full retrospective. It is a pure client-side bundle with local-only storage and no backend service required.
