➕ Adding New Prompts

Use the interactive CLI script (recommended):

./scripts/new-prompt.sh

The script walks you through:

1. Post title + source URL
2. Step loop — for each step: step title (Enter = default Prompt), optional image, prompt text, then "Add another step?"
3. Tags — AI-inferred from all step prompts combined, with interactive toggle
4. Preview → commit + push

Or manually add a new .md file in content/prompts/ following the format below, then push to main — GitHub Actions automatically rebuilds the site.

Single-prompt post

---
title: "Your Prompt Title"
num: 114
tags:
  - "Art Styles"       # pick from existing tags
cover: "https://github.com/user-attachments/assets/..."
source: "@handle"
sourceUrl: "https://x.com/..."
date: 2026-03-19

<img src="..." alt="..." />

### Prompt

> Your prompt text here...

Multi-prompt post (multiple steps)

Use ### Step N — Title headings to separate each step. Each step can have its own image, description, and prompt — all with individual Copy buttons.

title: "Activity Slide Deck"
num: 116
tags:
  - "Infographic & UI"
cover: "https://..."       # use first step's image for the card
source: "@handle"
sourceUrl: "https://x.com/..."

### Step 1 — Activity Overview

<img src="..." alt="..." />

*Optional description of what this prompt produces.*

> Generate an activity overview slide for a team workshop...

### Step 2 — Step Instructions

<img src="..." alt="..." />

*Optional description.*

> Generate step-by-step instruction slides...

from [@handle](https://x.com/...)

Rules:

• Each step starts with any h3 heading (### ...)
• Image and description are optional per step
• Prompt text is a > blockquote — each gets its own Copy button automatically
• cover in frontmatter is still required for the gallery card (use the first step's image)

🏷️ Managing Tags

Tag definitions are centrally managed in scripts/tags.sh.

Adding a new tag

1. Edit scripts/tags.sh — add one line to TAG_DEFS with format "slug|Human Label|kw1|kw2|..."
2. (Optional) Run ./scripts/migrate-tags.sh to retag existing prompts with the new taxonomy

Splitting or renaming a tag

1. Edit scripts/tags.sh — update or replace the relevant TAG_DEFS entry
2. Run ./scripts/migrate-tags.sh to let AI reclassify affected prompts
3. Hugo automatically removes tag pages that no prompts reference

Retagging prompts

# Retag a single prompt
./scripts/migrate-tags.sh content/prompts/115-black-and-white-photograph.md

# Retag all prompts (interactive, confirms each file)
./scripts/migrate-tags.sh

# Retag all prompts non-interactively (auto-accept AI suggestions)
./scripts/migrate-tags.sh --auto
