What it does

Prompt Build is an agent skill from AgriciDaniel/claude-prompts. Build custom AI prompts from scratch using guided workflows and patterns from a 2,500+ prompt database. Supports image, video, and text prompts for Midjourney, Flux, Leonardo AI, DALL-E, Sora, and 12 more models. Use when user says "build a prompt", "create a prompt", "write a prompt", "make me a prompt", "new prompt", or "prompt from scratch".

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering AI video generation. It works with Midjourney and OpenAI. The repository describes itself as: AI prompt database and builder skill for Claude Code. 2,500+ curated prompts across 19 categories and 17 AI models. The licence is MIT.

When your agent uses it

  • User says build a prompt
  • Create a prompt
  • Make me a prompt
  • Prompt from scratch

Example prompts

  • “build a prompt”
  • “create a prompt”
  • “write a prompt”
  • “/prompt-build”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Determine Intent
  2. Find Reference Prompts
  3. Construct the Prompt
  4. Apply Model-Specific Syntax
  5. Review and Refine

What it can do on your machine

Read from SKILL.md and the folder at commit 23e8ff9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prompt Build loads about 592 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 193 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~592

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Prompt Builder

Build production-quality AI prompts using patterns extracted from 2,500+ curated prompts.

Build Workflow

Step 1: Determine Intent

Ask the user (if not already clear):

  1. Output type: Image, Video, or Text?
  2. Target model: Which AI model? (Midjourney, Flux, DALL-E, Leonardo, Sora, etc.)
  3. Subject: What should the prompt create?
  4. Style/mood: Any specific aesthetic?
Step 2: Find Reference Prompts

Search the database for similar prompts to use as inspiration:

bash
python3 {PROMPT_ENGINE_DIR}/scripts/search_prompts.py "SUBJECT" --model MODEL --limit 5
Step 3: Construct the Prompt

Use this universal structure (adapt per model):

Image Prompts:

[Subject/Action] + [Setting/Environment] + [Lighting/Mood] + [Camera/Lens] +
[Style Reference] + [Technical Parameters]

Video Prompts:

[Camera Movement] + [Subject/Action] + [Setting] + [Lighting] +
[Duration/Speed] + [Style] + [Technical]

Text Prompts:

[Role/Context] + [Task] + [Constraints] + [Format] + [Tone] + [Examples]
Step 4: Apply Model-Specific Syntax

Load {PROMPT_ENGINE_DIR}/references/model-guide.md for model-specific formatting rules:

  • Midjourney: Use --ar, --v, --style, --s, --chaos
  • Flux: Natural language, detailed descriptions work best
  • DALL-E: Direct, descriptive, avoid negative prompts
  • Leonardo AI: Use model-specific keywords (Phoenix, Alchemy)
  • Sora: Camera movements, scene transitions, temporal descriptions
Step 5: Review and Refine

Present the prompt with:

  1. The full prompt text
  2. Recommended parameters/settings
  3. Similar prompts from the database for comparison
  4. Suggested variations (3 alternatives)

Quality Gates

  • Prompt must be > 30 characters
  • Must include subject + at least one modifier (style, lighting, or camera)
  • Must use model-appropriate syntax
  • No conflicting instructions (e.g., "realistic" + "cartoon")
