Publishing Guide

Publish your own specialist agent

Specialist agents are JSON manifests that define instructions, delegation guidance, allowed tools, and model settings. Publish a standalone agent or extend a built-in role with a focused prompt overlay.

Standalone Specialist Agent

A self-contained agent with its own instructions, allowed tools, MCP servers, and model configuration.

Built-in Role Extension

Extends a core role (explorer, librarian, oracle, designer, fixer, or observer) with a targeted prompt overlay. The marketplace gives it that role's visual identity and baseline capabilities.

Contribution Workflow

1 Author Manifest

Define your agent in a package.json file with an identifier (<publisher>/<package>), version, prompt, delegation guidance, and tools. Optionally include an avatar.webp alongside the manifest; the website uses it when the versioned registry asset exists and otherwise keeps the built-in-role or operator fallback.

packages/v3/<pub>/<pkg>/<ver>/package.json
2 Test Locally

Import the manifest into OpenCode and check its instructions, delegation guidance, and tools before submitting.

bunx oh-my-opencode-slim marketplace import
3 Submit Pull Request

Submit a PR to the marketplace repository. CI checks the manifest and makes each published version immutable.

github.com/alvinunreal/oh-my-opencode-marketplace
Local Import Command
bunx oh-my-opencode-slim marketplace import ./package.json

Run in your package directory to test manifest and tools before opening a PR.
