What automation engineers need from AI prompt and snippet managers

Automation engineers build and reuse scripts, commands and prompts, often on more than one machine. A saved prompt has to be quick to bring back and easy to change, so a library that opens quickly from the keyboard saves time. Teamwork adds another need: everyone has to insert the same text, which makes a shared or exportable library useful. Much of this work happens beside AI assistants, so an engineer may want one library that reaches the assistants already in use. A tool inside the editor used every day avoids switching windows, while a separate app is one more thing to open. Price and where the data is stored are worth settling before committing. None of these tools does every job, so the sections below report what each source says and nothing more.
