OpenCode ECC Plugin

WARNING: This README is specific to OpenCode usage. If you installed ECC via npm (e.g. npm install opencode-ecc), refer to the root README instead.

ECC plugin for OpenCode - agents, commands, hooks, and skills.

Installation

Installation Overview

There are two ways to use ECC:

1. npm package (recommended for most users) Install via npm/bun/yarn and use the ecc-install CLI to set up rules and agents.

2. Direct clone / plugin mode Clone the repository and run OpenCode directly inside it.

Choose the method that matches your workflow below.

Option 1: npm Package

npm install ecc-universal

Add to your opencode.json:

{
  "plugin": ["ecc-universal"]
}

This loads the ECC OpenCode plugin module from npm:

• hook/event integrations
• bundled custom tools exported by the plugin

It does not auto-register the full ECC command/agent/instruction catalog in your project config. For the full OpenCode setup, either:

• run OpenCode inside this repository, or
• copy the relevant .opencode/commands/, .opencode/prompts/, .opencode/instructions/, and the instructions, agent, and command config entries into your own project

After installation, the ecc-install CLI is also available:

npx ecc-install typescript

Option 2: Direct Use

Clone and run OpenCode in the repository:

git clone https://github.com/affaan-m/ECC
cd ECC
opencode

If you also want to apply the ECC home install (node scripts/install-apply.js --target opencode --profile full), build the plugin first so the compiled payload at .opencode/dist/ exists:

node scripts/build-opencode.js   # or: npm run build:opencode
node scripts/install-apply.js --target opencode --profile full

Without .opencode/dist/index.js, OpenCode will detect the slash commands but silently skip plugin hooks and tools. The installer now fails fast with a pointer to this command if the build step is missing.

Hook Event Mapping

OpenCode's plugin system maps to Claude Code hooks:

Claude Code	OpenCode
PreToolUse	tool.execute.before
PostToolUse	tool.execute.after
Stop	session.idle
SessionStart	session.created
SessionEnd	session.deleted

OpenCode has 20+ additional events not available in Claude Code.

Hook Runtime Controls

OpenCode plugin hooks honor the same runtime controls used by Claude Code/Cursor:

export ECC_HOOK_PROFILE=standard
export ECC_DISABLED_HOOKS="pre:bash:tmux-reminder,post:edit:typecheck"

• ECC_HOOK_PROFILE: minimal, standard (default), strict
• ECC_DISABLED_HOOKS: comma-separated hook IDs to disable

Skills

The default OpenCode config loads 11 curated ECC skills via the instructions array:

• coding-standards
• backend-patterns
• frontend-patterns
• frontend-slides
• security-review
• tdd-workflow
• strategic-compact
• eval-harness
• verification-loop
• api-design
• e2e-testing

Additional specialized skills are shipped in skills/ but not loaded by default to keep OpenCode sessions lean:

• article-writing
• content-engine
• market-research
• investor-materials
• investor-outreach
