Versed Code Review Action

AI-powered code review for your GitHub pull requests, powered by Versed.

Versed analyzes your PR diff against your team's custom rules and posts a structured review comment directly on the pull request — including a pass/fail verdict, flagged issues by severity and file, and actionable suggestions.

---

Quick Start

Add this workflow file to your repository at .github/workflows/versed.yml:

name: Versed Code Review

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  review:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write

    steps:
      - uses: Magnet-js/Versed-action@v1
        with:
          api_token: ${{ secrets.VERSED_API_TOKEN }}
          repo_id: ${{ secrets.VERSED_REPO_ID }}

---

Setup

1. Sign up at useversed.com and connect your GitHub account.
2. Register your repository and write a custom system prompt — your team's coding rules (e.g. "Enforce TypeScript strict mode. No any types. Functions must not exceed 50 lines.").
3. Copy your API token and Repo ID from the Versed dashboard.
4. Add them as secrets in your GitHub repository:
   • Go to Settings → Secrets and variables → Actions
   • Add VERSED_API_TOKEN — your API token
   • Add VERSED_REPO_ID — your Repo ID (a number shown in the dashboard)
5. Add the workflow file shown in Quick Start to your repository.

Inputs

Input	Required	Default	Description
api_token	Yes	—	Your Versed API token. Store as a GitHub secret.
repo_id	Yes	—	Your Versed Repo ID (found in the dashboard).
api_url	No	https://api.useversed.com	Versed API base URL. Only needed for self-hosted deployments.

Permissions

The action requires pull-requests: write to post and update the review comment. Declare this explicitly in your job:

jobs:
  review:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write   # required

Without this permission the action will fail with a 403 error when attempting to post the comment.

What the Action Does

1. Posts a placeholder comment on the PR immediately — so reviewers know a review is in progress.
2. Fetches the PR diff via the GitHub API (up to 50,000 characters).
3. Sends the diff and PR title to the Versed backend, which runs your custom rules through Gemini 2.5 Flash.
4. Updates the comment with the full review: a pass/fail verdict, an issues table (severity · file · description), and a suggestions list.

Review Comment Example

## 🔍 Versed Code Review — ✅ Passed

The changes look good overall. One minor style issue was noted in the auth module.

### Issues

| Severity | File | Description |
|----------|------|-------------|
| WARNING | src/auth/token.ts | Function `validateToken` exceeds the 50-line limit |

### Suggestions

- Consider extracting the expiry check logic into a `isExpired` helper for reuse.
