dsh-dev-toolbox

Pretty-printing a JSON blob in a new tab, hand-converting URL query params into an object, or calculating a timestamp off the top of your head—these are the small tasks that break your flow yet never quite justify leaving the editor. dsh-dev-toolbox folds a set of everyday text utilities directly into the dsh composer toolbar: one click on the code icon opens a panel where every conversion runs locally in the browser, with no model call, no network request, and nothing written to disk.

The toolbox covers five high-frequency scenarios: JSON formatting, minification, validation, and string escaping and unescaping; URL percent-encoding and decoding plus bidirectional query-string-to-JSON conversion; UTF-8 text to Base64 and back; timestamp parsing that accepts 10-digit seconds, 13-digit milliseconds, fractional seconds, and ISO strings, yielding Unix seconds, Unix milliseconds, ISO, and local time in a single pass; and UUID v4 generation via crypto.randomUUID. Built-in extras include output search with regex and case-sensitivity options, a full-screen reading view, and three global footer actions—load from composer, copy output, and insert back into the draft—so results flow straight back into the conversation.

It is aimed at engineers who already work inside dsh for coding, prompt engineering, or API response handling: any moment in a session where you need a quick text transformation and would rather not switch windows. Open the panel, paste, click, and the answer is right there.
