A Prompt Library:

Prompts

A curated collection of prompts for working with LLMs — for coding, debugging, architecture, writing, and more. Each prompt is a tool shaped by use.

The Prototype Interview

Before writing a line of code, have the AI interview you about your vision. 50 rapid-fire questions extract design decisions and judgment you didn't know you had — then the model can one-shot a working prototype roughly aligned with the picture in your head.

Critique This Prototype

After you've built something, have the AI tear it apart — not as a code reviewer, but as a product thinker. What assumption is each screen testing? Where does the vision leak? High fidelity can mask the absence of shared understanding.

Prototype to Production

The prototype works and the concept is validated — now harden it for production. This prompt walks through the unglamorous work of turning a vibe-coded draft into code you'd actually ship.

Give Me Five Directions

When you're stuck on what to build or how to approach a problem, ask for five wildly different directions — not variations on a theme. Forces the model out of its clustering tendency and into genuinely divergent territory.

The Careful Coder's Manifesto

Operating principles for agentic code intelligence — measure twice, cut once.

Code Smells from First Principles

Why code smells exist, grounded in cognitive science and information theory.

Code Quality Auditor Framework

Structured 3-phase audit prompt for identifying and eliminating quality-lowering patterns.

Meeting Transcription Context

Transform meeting transcriptions into publication-quality documentation with decisions, action items, and reasoning.

Edge Cases You Didn't Consider

After plan mode, force the model to audit its own blind spots. It's silly that it works, but it does — asking the model to reflect on what it missed surfaces real gaps.

Make It Simpler and Dumber

Push back on over-engineering by asking for the dumbest possible solution that still achieves the goal. Models tend toward complexity — this resets the bar.

Capitalize for Emphasis

Does capitalizing words for emphasis actually work, or is it placebo? Consensus leans toward: it works. CAPITALIZED words signal priority and weight to the model.
