OpenCode integration

This integration exposes OpenCodeReview as native tools and slash commands in OpenCode.

It registers:

ocr_review — review workspace changes, one commit, or a ref range and return structured JSON findings.
ocr_health — show the installed OCR version and test its configured LLM connection.
/ocr-review and /ocr-health — convenient prompts that invoke the tools.

Existing user commands with either name are preserved.

Prerequisites

Install and configure OpenCodeReview first:

npm install -g @alibaba-group/open-code-review
ocr config provider
ocr config model
ocr llm test

Install globally

mkdir -p ~/.config/opencode/plugins
curl -fsSL \
  https://raw.githubusercontent.com/alibaba/open-code-review/main/plugins/open-code-review/opencode/open-code-review.ts \
  -o ~/.config/opencode/plugins/open-code-review.ts

Restart OpenCode after installation.

Install for one project

Run this from the project root:

mkdir -p .opencode/plugins
curl -fsSL \
  https://raw.githubusercontent.com/alibaba/open-code-review/main/plugins/open-code-review/opencode/open-code-review.ts \
  -o .opencode/plugins/open-code-review.ts

Commit the plugin file if the integration should be shared with the project.

Usage

Use the registered commands:

/ocr-review current workspace; focus on authentication regressions
/ocr-review compare main to feature/auth-refresh
/ocr-health

Or ask OpenCode naturally:

Use ocr_review to review my current changes. The goal is to add rate limiting
without changing the public API.

Set preview to true to inspect which files would be reviewed without making an LLM request.

Behavior and safety

Reviews use --audience agent and JSON output.
The process is launched with an argument array and shell: false.
Reviews have a 15-minute overall timeout and a 10 MiB output limit.
Cancelling the OpenCode tool terminates the OCR process.
OCR credentials remain in the existing OCR configuration or environment.
Workspace mode includes staged, unstaged, and untracked files.

Development

cd plugins/open-code-review/opencode
npm install
npm run check
