opencode-plugin-cc

Use OpenCode from inside Claude Code for code reviews or delegated tasks.

This plugin mirrors the workflow shape of codex-plugin-cc, but delegates to the local opencode CLI.

What You Get

• /opencode:review for a read-only OpenCode review
• /opencode:adversarial-review for a steerable challenge review
• /opencode:rescue, /opencode:status, /opencode:result, and /opencode:cancel to delegate work and manage background jobs
• /opencode:setup to check local OpenCode readiness and toggle the optional stop-time review gate

Requirements

• Node.js 22.18 or newer
• OpenCode CLI installed and authenticated

Install

Add the marketplace in Claude Code:

/plugin marketplace add skillsland/opencode-plugin-cc

Install the plugin:

/plugin install opencode@skillsland-opencode

The marketplace entry installs the published opencode-plugin-cc npm package, so the package must be published before this command can install a working plugin.

Reload plugins:

/reload-plugins

Then run:

/opencode:setup

/opencode:setup will tell you whether Node.js, OpenCode, and OpenCode authentication are ready.

Plugin runs use OpenCode's built-in build agent in --pure mode by default so external OpenCode plugins cannot change the agent type or break basic commands. Pass --agent <name> on a command when you want another primary OpenCode agent. Set OPENCODE_COMPANION_PURE=0 before launching Claude Code if you explicitly want OpenCode plugin loading for companion runs.

If you need to install OpenCode, use:

curl -fsSL https://opencode.ai/install | bash

If OpenCode is installed but not logged in yet, run:

!opencode providers login

After install, you should see:

• the slash commands listed below
• the opencode:opencode-rescue subagent in /agents

One simple first run is:

/opencode:review --background
/opencode:status
/opencode:result

Usage

/opencode:review

Runs a read-only OpenCode review on your current git state.

Examples:

/opencode:review
/opencode:review --base main
/opencode:review --background

/opencode:adversarial-review

Runs a review that challenges the implementation approach and design assumptions.

Examples:

/opencode:adversarial-review
/opencode:adversarial-review --base main challenge the retry and rollback design
/opencode:adversarial-review --background look for race conditions

/opencode:rescue

Delegates an investigation or fix request to OpenCode.

Examples:

/opencode:rescue investigate why tests are failing
/opencode:rescue --write fix the failing test with the smallest safe patch
/opencode:rescue --model anthropic/claude-sonnet-4-5 --variant high inspect this regression
/opencode:rescue --background --write implement the missing edge case

Notes:

• The plugin never adds --dangerously-skip-permissions unless you explicitly ask for it.
• Follow-up rescue requests can resume the latest tracked OpenCode task when an OpenCode session ID is available.

Job Management

/opencode:status
/opencode:status <job-id>
/opencode:result
/opencode:result <job-id>
/opencode:cancel
/opencode:cancel <job-id>

Review Gate

/opencode:setup --enable-review-gate
/opencode:setup --disable-review-gate

When enabled, the plugin uses a Claude Code Stop hook to run a compact OpenCode review of the previous Claude turn. If OpenCode returns BLOCK: ..., the stop is blocked so Claude can address the issue first.

Development

Requirements:

• Node.js 22.18 or newer
• pnpm 10.33 or newer

Install dependencies:

pnpm install

Run the full local quality gate:

pnpm run check

Useful scripts:

• pnpm run build - bundle TypeScript into dist/ with tsdown
• pnpm run typecheck - run TypeScript without emitting files
• pnpm run lint - run ESLint with type-aware TypeScript rules
• pnpm run test - run Vitest once
• pnpm run format - format the repo with Prettier
• pnpm run changeset - create a Changesets release note
• pnpm run commit - write a Conventional Commit with Commitizen
