Prompt templates: stop rewriting the same prompt

Look at the prompts you retype most, and you'll notice they're rarely fixed text. They're a pattern with a blank in it: "Summarize this {{document}} for a {{audience}} in {{tone}}." Every time you paste one and hand-edit the blanks, you're doing work a prompt template should do for you. Here's the pattern.

The template pattern

Write the prompt once, and mark the parts that change with placeholders:

Rewrite this cold email to a {{role}} at a {{industry}} company. Keep it under {{word_count}} words.

Now it's not one prompt — it's a family of prompts. The skeleton (instructions, constraints, structure) stays constant, and only the blanks move. That's where the quality lives: you tune the skeleton once, and every future use inherits it.

Why this beats copy-paste editing

• Consistency — the parts that make a prompt good stay identical, instead of drifting as you hand-edit.
• Speed — you fill three blanks instead of rereading and rewriting a paragraph.
• Reuse — one good template replaces a folder full of near-identical prompts.

Two rules keep templates clean: put the stable instructions first and the variable inputs last (it also helps AI providers cache the stable prefix, which lowers cost on long prompts), and name variables for what they are ({{audience}}, not {{x}}).

Running templates without the busywork

A template is only useful if filling it is faster than editing text. That's why variables are built into Prompt Vault: save a prompt with {{variables}}, and when you insert it, it asks you to fill the blanks, then drops the finished prompt straight into ChatGPT, Claude, or Gemini. No find-and-replace, no leaving the chat.

Your best prompt isn't a string, it's a shape. Save the shape, not the string. Next: organize your prompt library.
