Prompt Engine -- Ultimate AI Prompt Database and Builder

2,500+ curated prompts across 19 categories, 17 AI models, and 4 output types.

Quick Reference

Command	What it does
`/prompt [query]`	Search prompts by keyword, category, model, or style
`/prompt-build`	Build a custom prompt from scratch with guided workflow
`/prompt-enhance`	Enhance an existing prompt with pro techniques
`/prompt-adapt`	Adapt a prompt for a different AI model
`/prompt-library`	Browse, filter, and explore the full prompt library

Orchestration Logic

If user provides a search query or asks to find/search -> run search workflow below
If user wants to create/build a new prompt -> route to /prompt-build
If user has an existing prompt to improve -> route to /prompt-enhance
If user wants to convert between models -> route to /prompt-adapt
If user wants to browse/explore -> route to /prompt-library
If ambiguous, show the Quick Reference table and ask

Search Workflow (Default /prompt)

When user provides a search query:

Run the search script:

python3 {PROMPT_ENGINE_DIR}/scripts/search_prompts.py "QUERY" [--category CAT] [--model MODEL] [--type TYPE] [--limit N]

Present results as a numbered list with:
- Prompt text (truncated to 200 chars for preview)
- Category, model, output type
- Tags/styles if available
Let user select a prompt to see full details, or refine their search

Error Handling

0 search results: Suggest broadening the query, trying different keywords, or removing filters. Offer to show available categories with --categories.
Script fails: Verify Python 3.10+ is available (python3 --version). Check that the database exists at {PROMPT_ENGINE_DIR}/prompts/all_prompts.json.
Empty or short prompt input: For /prompt-enhance and /prompt-adapt, ask the user to provide a longer prompt (minimum 30 characters).

academic-pptx

Free

Use this skill whenever the user wants to create or improve a presentation for an academic context — conference papers, seminar talks, thesis defenses, grant briefings, lab meetings, invited lectures, or any presentation where the audience will evaluate reasoning and evidence. Triggers include: 'conference talk', 'seminar slides', 'thesis defense', 'research presentation', 'academic deck', 'academic presentation'. Also triggers when the user asks to 'make slides' in combination with academic content (e.g., 'make slides for my paper on X', 'create a presentation for my dissertation defense', 'build a deck for my grant proposal'). This skill governs CONTENT and STRUCTURE decisions. For the technical work of creating or editing the .pptx file itself, also read the pptx SKILL.md.
