Stop losing your prompt engineering work

Context switching is what kills my momentum during a deep work session. I'll spend a good chunk of time tweaking a prompt to get Claude or ChatGPT to handle a messy stack trace or a complex refactor, only to realize ten minutes later that I’ve lost the thread in a sea of old chat history. Re-engineering that same prompt for the fifth time in a week isn't just annoying; it's a failure in workflow design. If a prompt actually works, it should be treated like any other piece of reusable code, not a disposable one-off.

I used to keep a running list in a Google Doc, but the friction of switching tabs every time I needed a specific instruction was too high. I need things to stay within the flow of the IDE or the browser window. I've been testing out a Chrome extension called PromptStash to bridge that gap. It lets you save templates and inject them straight into the LLM input box without leaving the page.

The most useful part for actual shipping is how it handles variables. Instead of hunting through a text file to copy-paste and then manually editing a prompt to change the context, you can use placeholders. If I need to generate a changelog or a specific code review, I don't want to rewrite the scaffolding every single time. I use a template structure like this:

Rewrite the text below in a {{tone}} tone for a {{audience}} audience.

When it's time to use it, the extension just prompts me to fill in the blanks. It turns a tedious editing chore into a structured task, which is much better for maintainability and consistency in my output. If you want to see how it works, check these out:
