Agent Plugin Builder

Universal plugin creation for AI agents.

Install the builder as a skill, then scaffold shareable plugin repos with adapters, installers, docs, tests, and GitHub Pages.

Use now Sponsor

Install first npx github:Kokoabassplayer/agent-plugin-builder install --target codex

Universal plugin creation flow from one Agent Skill core to adapters, installers, docs, tests, and funding

How to use

Install the builder. Ask your agent. Generate plugins.

Install Agent Plugin Builder into your harness first. After that, ask your agent to use $agent-plugin-builder and it can scaffold plugin repos with skills, adapters, installers, docs, tests, and sponsor-ready project surfaces.

Install the builder skill

npx github:Kokoabassplayer/agent-plugin-builder install --target codex

Use it in your agent

Start a fresh agent session after installing, then invoke the builder skill by name.

Use $agent-plugin-builder to create a plugin repo for visual evidence comments.

Create a plugin repo directly

npx github:Kokoabassplayer/agent-plugin-builder create visual-evidence-kit --description "Capture proof for reviewers."

Install the generated skill

Run the target line for your harness from inside the generated repo.

cd visual-evidence-kit
node packages/installer/bin/install.mjs --target codex

Build the repo around the skill.

Works with every agent

One skill core. Multiple harnesses.

Keep the reusable behavior in the skill. Let generated adapter files explain how Codex, Claude Code, OpenClaw, Gemini CLI, and generic Agent Skills should pick it up.

CodexGlobal skill folder and repo-local guidance.

Claude CodeCompatible SKILL.md package structure.

OpenClawAdapter metadata for first-run discovery.

Gemini CLIGeneric instruction handoff for skill use.

Any harnessPlain scripts, docs, and predictable file layout.

Escape the one-off plugin repo.

Current builder outputs

Everything a public plugin repo needs.

The generated project is meant to be readable by humans, installable by users, and usable by multiple agent harnesses without rewriting the core idea.

Skill package

Creates a valid Agent Skill with room for scripts, references, examples, and assets.

Harness adapters

Documents the same capability for Codex, Claude Code, OpenClaw, Gemini CLI, and generic agents.

Installer package

Creates a Node CLI package plus shell and PowerShell wrapper paths for cross-platform use.

Docs site

Starts a GitHub Pages-ready documentation surface for install instructions and examples.

Verification loop

Adds smoke tests and package checks so users can trust the generated repo before publishing.

Command builder

Create the terminal sequence before you leave the page.

Choose the plugin name, description, and target harnesses. The terminal sequence updates instantly and can be copied into any terminal.

terminal

npx github:Kokoabassplayer/agent-plugin-builder create visual-evidence-kit --description "Capture proof for reviewers"
cd visual-evidence-kit
node packages/installer/bin/install.mjs --target codex
node packages/installer/bin/install.mjs --target claude-code
node packages/installer/bin/install.mjs --target openclaw
