skills AGENTS.md

Repository instructions for AI coding agents, stored in an AGENTS.md file. They explain how the Prisma skills repository is organized and how to create new skills.

In plain words
What is it for?
Use them when working on this repository, especially when adding a skill, choosing folders and filenames, or following the required SKILL.md format.
Why use it?
They give coding agents and contributors shared rules for finding, naming, and structuring skills in the repository.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

skills AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md

This file provides guidance to AI coding agents (Claude Code, OpenCode, Cursor, Copilot, etc.) when working with code in this repository.

Repository Overview

A collection of skills for AI coding agents working with Prisma ORM. Skills are packaged instructions and rules that extend agent capabilities for database development, query optimization, and best practices.

Creating a New Skill

Directory Structure

skills/
  {skill-name}/           # kebab-case directory name
    SKILL.md              # Required: skill definition with frontmatter
    references/           # Optional: individual reference files
      {category}-{rule}.md # Individual references

Naming Conventions

  • Skill directory: kebab-case, prefixed with prisma- (e.g., prisma-schema-best-practices)
  • SKILL.md: Always uppercase, always this exact filename
  • Reference files: {category}-{rule-name}.md in kebab-case (e.g., relations-explicit-names.md)
  • Categories: Use consistent prefixes matching the skill's category table

# Prisma {Skill Title}

{Brief description of what the skill covers.}

## When to Apply

{Bullet list of scenarios when this skill should be used}

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | {Category} | CRITICAL | `{prefix}-` |
| 2 | {Category} | HIGH | `{prefix}-` |
...

## Quick Reference

### 1. {Category} (CRITICAL)

- `{prefix}-{rule}` - Brief description
- `{prefix}-{rule}` - Brief description

### 2. {Category} (HIGH)
...

## How to Use (Optional)

If the skill includes references, read individual reference files for detailed explanations and code examples:

references/{prefix}-{rule}.md


Each reference file contains:
- Brief explanation of why it matters
- Incorrect code example with explanation
- Correct code example with explanation
- Additional context and references

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
