PR Reviewer Assignment Guide

Analyze PR changed files and assign appropriate reviewer(s) by posting a comment.

Workflow

Step 1: Get PR Details and Changed Files

gh pr view [PR_NUMBER] --json number,title,body,files,labels,author

Step 2: Map Changed Files to Feature Areas

Analyze file paths to determine which feature area(s) the PR touches, then use team-assignment.md to find the appropriate reviewer(s).

Use the PR title, description, and changed file paths together to infer the feature area. For example:

• packages/database/ → deployment/backend area
• apps/desktop/ → desktop platform
• Files containing KnowledgeBase, Auth, MCP etc. → corresponding feature labels in team-assignment.md

Step 3: Check Related Issues

If the PR body references an issue (e.g., close #123, fix #123, resolve #123), fetch that issue's participants:

gh issue view [ISSUE_NUMBER] --json author,comments --jq '{author: .author.login, commenters: [.comments[].author.login]}'

Team members who created or commented on the related issue are strong candidates for reviewer.

Step 4: Determine Reviewer(s)

Apply in priority order:

1. Exclude PR author - Never assign the PR author as reviewer
2. Related issue participants - Team members from team-assignment.md who are active in the related issue
3. Feature area owner - Based on changed files and team-assignment.md Assignment Rules
4. Multiple areas - If PR touches multiple areas, mention the primary owner first, then secondary
5. Fallback - If no clear mapping, assign @arvinxx

Step 5: Post Comment

Post a single comment mentioning the reviewer(s). Use the Comment Templates from team-assignment.md, adapting them for PR review context.

gh pr comment [PR_NUMBER] --body "message"

Important Rules

1. PR author exclusion: ALWAYS skip the PR author from reviewer list
2. One comment only: Post exactly ONE comment with all mentions
3. No labels: Do NOT add or remove labels on PRs
4. Bot PRs: Skip PRs authored by bots (e.g., dependabot, renovate)
5. Draft PRs: Still assign reviewers for draft PRs (author may want early feedback)
