AGENT_RULES

Browse, install, and own your AI coding configurations.

One command to install pre-built configurations for AI coding assistants.
Files are copied to your project — then they're yours to customize.

It's like the shadcn for agentic coding configs.

npx @agentrules/cli add agentic-dev-starter --platform opencode

What is AGENT_RULES?

AGENT_RULES is a CLI for installing pre-built configurations for AI coding assistants like OpenCode, Claude Code, Cursor, and Codex.

Unlike plugins that are managed for you, AGENT_RULES rules are copied directly into your project. They're just files — view them, edit them, evolve them as your workflow changes.

• Browse rules at agentrules.directory
• Install with one command
• Own the files — modify freely, no updates overwriting your changes

Quick Start: Install a Rule

# Install a rule to your project
npx @agentrules/cli add <rule-name> --platform <platform># Example: Install the agentic-dev-starter rule for OpenCode
npx @agentrules/cli add agentic-dev-starter --platform opencode

Files are copied to the platform's config directory (e.g., .opencode/ for OpenCode). That's it — they're yours now.

Supported Platforms

Platform	Project Directory	Global Directory
OpenCode	.opencode/	~/.config/opencode
Claude Code	.claude/	~/.claude
Cursor	.cursor/	~/.cursor
Codex	.codex/	~/.codex

More Install Options

# Install globally (for all projects)
npx @agentrules/cli add <rule> --platform <platform> --global
# Install a specific version
npx @agentrules/cli add <rule> --platform <platform> --version 1.0
# See what would be installed without writing files
npx @agentrules/cli add <rule> --platform <platform> --dry-run

See the CLI documentation for all options.

Quick Start: Create & Publish a Rule

Share your agentic workflow and get discovered. Publishing to agentrules.directory gives you a profile page, puts your work in front of developers, and popular rules get featured in trending.

1. Add config to your platform directory

If you already have a .opencode/, .claude/, or other platform directory with your configs, just add an agentrules.json file:

cd .opencode
npx @agentrules/cli init

The init command guides you through the publishing fields (with sensible defaults). Your rule structure is simply:

.opencode/
├── agentrules.json # Rule config
├── AGENTS.md # Your existing files
└── commands/
└── review.md

2. Login

npx @agentrules/cli login

This opens a browser for authentication.

3. Publish

npx @agentrules/cli publish .opencode

That's it! Your rule is now discoverable at agentrules.directory. You'll get a profile page showcasing all your published rules, and popular rules get featured in trending.

Rule Format

Rules use agentrules.json for configuration:

{
"$schema": "https://agentrules.directory/schema/agentrules.json",
"name": "my-rule",
"title": "My Rule",
"description": "A helpful rule for...",
"license": "MIT",
"platforms": ["opencode"],
"tags": ["productivity", "typescript"],
"version": 1,
"features": ["Smart code review", "Auto-formatting"],
"ignore": ["*.log", "test-fixtures"]
}

Field	Required	Description
name	Yes	URL-safe identifier (lowercase, hyphens)
title	Yes	Display name
description	No	Short description (max 500 chars; recommended)
license	Yes	SPDX license identifier (e.g., MIT)
platforms	Yes	Array of target platforms: opencode, claude, cursor, codex
tags	No	0-10 tags for discoverability (recommended)
version	No	Major version (default: 1)
features	No	Up to 5 key features to highlight
ignore	No	Additional patterns to exclude from bundle

Rule Structure

.
├── agentrules.json # Rule config
├── README.md # Shown on registry page (optional, not bundled)
├── LICENSE.md # License text (optional, not bundled)
├── INSTALL.txt # Shown after install (optional, not bundled)
├── AGENTS.md # Instruction file (optional)
└── command/
└── review.md

By default, files are collected from the config directory and bundled under the platform prefix (e.g. command/review.md → .opencode/command/review.md).

Auto-Excluded Files

These files are automatically excluded from bundles:

• node_modules/, .git/, .DS_Store
• Lock files: package-lock.json, bun.lockb, pnpm-lock.yaml, *.lock

Use the ignore field for additional patterns (e.g., ["*.log", "tmp"]).
