# Prompt-Library Builder

If you use AI regularly, you retype variations of the same requests constantly — the email rewriter, the meeting summarizer, the code explainer. A prompt library captures your best versions once, parameterized and organized, so you invoke them instead of reinventing them. This builds yours: identifies your recurring tasks, turns them into reusable templates, and sets up a system to store and improve them — a toolkit that gets more valuable every time you add to it.

## What This Skill Produces

- **Your recurring tasks, captured** — the AI requests you make repeatedly, identified and listed
- **Reusable prompt templates** — each turned into a clean, parameterized template (clear role, the inputs to fill in, and the desired output format) instead of a one-off
- **An organization scheme** — a simple way to categorize and find prompts (by task, by domain, by frequency)
- **The reusability principles** — what makes a prompt reusable and reliable (specific role, explicit inputs, defined output, examples where helpful)
- **A storage & improvement system** — where to keep them (a doc, snippets, a tool) and how to refine each as you use it
- **A starter set** — a few of your most-used prompts, templated and ready

## Required Inputs

Ask for these if not provided:
- **Your recurring AI tasks** — the things you ask AI to do often (or a prompt to help surface them)
- **A few examples** — prompts you've written that worked, to templatize
- **Your tools** — where you'll store/use them (a notes app, snippet manager, the AI tool itself)
- **Your domains** — work, personal, coding, writing (for organizing)

## Framework: Capture, Templatize, Organize

1. **Find the repeats.** Identify the requests you make again and again — these are the highest-value candidates to templatize.
2. **Templatize for reuse.** Turn each into a clean template: a clear role/instruction, the variable inputs to fill in `[like this]`, and the output format you want — so it works every time with just the specifics swapped.
3. **Add what makes it reliable.** Specific instructions, an output format, and an example or two where the task is fuzzy — the difference between a prompt that mostly works and one that always does.
4. **Organize for retrieval.** A simple scheme (by task type or domain) so you can actually find the right prompt when you need it — a library you can't search is a graveyard.
5. **Store where you'll use it.** Match storage to your workflow (a snippet tool, a doc, saved prompts) so invoking one is faster than rewriting.
6. **Improve continuously.** Refine each template as you notice what's missing — and add new ones as new repeats emerge. The library compounds.

## Output Format

### Prompt library: domains [x] · store in [y]

**Your recurring tasks:** [the repeats, identified].
**Templated (starter set)**
> **[Task name]:** [role/instruction] · inputs: `[fill these]` · output: [format]. — reusable.
> **[Task name]:** …

**What makes them reusable:** clear role · explicit `[inputs]` · defined output · an example where fuzzy.
**Organize by:** [task type / domain] so you can find them.
**Store in:** [snippets / doc / saved prompts] for fast invoking.
**Improve:** refine each as you use it; add new repeats as they emerge.

## Quality Checks
- [ ] Identifies the person's genuinely recurring AI tasks
- [ ] Turns them into parameterized, reusable templates (role/inputs/output)
- [ ] Explains what makes a prompt reliably reusable
- [ ] Provides an organization scheme for retrieval
- [ ] Matches storage to the person's workflow
- [ ] Includes a starter set and an improvement loop

## Anti-Patterns
- **Saving one-off prompts** verbatim with no parameterization.
- **A pile with no organization** — can't find anything.
- **Vague templates** missing the output format.
- **Storing where it's slower** to retrieve than to rewrite.
- **Never refining** the templates.

## Example Trigger Phrases

- "I keep rewriting the same prompts — turn them into reusable templates."
- "Organize my prompts so I can actually find and reuse them."
- "Templatize this prompt I use all the time."
- "Set up a personal prompt toolkit."
