An AI-powered code review dashboard for real GitHub pull requests. Paste a PR URL, inspect the actual changed files, stream an SDK-powered review over the real PR diff, and copy or optionally post the generated review.

Getting started

Install dependencies:

bun install
bun run build:sdk

Set an API key:

export CLINE_API_KEY="cline_..."

Optionally set a GitHub token. Public PRs can be loaded without one, but a token is recommended for private repositories and higher rate limits:

export GITHUB_TOKEN="github_pat_..."

Run the dashboard:

bun dev

Open http://localhost:3457, paste a GitHub pull request URL, and click Run Review.

By default the app copies the generated review to your clipboard. To allow posting a summary comment back to GitHub, run with both GITHUB_TOKEN and:

export ENABLE_GITHUB_REVIEW_POSTING=1

What it does

Fetches a real GitHub PR, including metadata, changed files, patches, and check status
Renders the PR in a dashboard with file navigation, diff view, review lanes, and finding cards
Sends the real PR diff to an agent with three custom tools:
- get_file_context - reads full file contents from the PR head commit for surrounding context
- add_review_finding - records a structured finding with file, line, severity, category, and suggestion
- submit_review - a completion tool that ends the run with a summary and approve/request-changes decision
Streams findings to the browser via Server-Sent Events as the agent reviews the PR
Copies the final review locally, or posts it as a GitHub PR comment when explicitly enabled

Concepts demonstrated

Multiple createTool definitions with zod schemas
lifecycle: { completesRun: true } to make a tool end the agent loop
Rich systemPrompt with structured instructions
Event subscription filtered by tool name
GitHub REST API integration for pull request metadata and diffs
Server-Sent Events (SSE) for a live review dashboard
Guarded external writes through an explicit posting opt-in
