 # GitHub Copilot Code Review Instructions
 
-## Focus Areas
+## Core Principles
 
-This document guides Copilot code review on two key areas:
+**CHECK REQUESTER AUTHORIZATION FIRST:**
+
+Before providing any review, verify if the person who requested the Copilot review is a member of the `@freecodecamp/staff` team.
+
+- If the requester is NOT part of `@freecodecamp/staff`, respond with ONLY this message:
+  ```
+  Please use AI reviews in your local environment, and leave this feature to be used by fCC mods and Staff.
+  ```
+  Do not provide any other feedback or review comments.
+
+- If the requester IS part of `@freecodecamp/staff`, proceed with the review following the guidelines below.
+
+---
+
+**BE EXTREMELY MINIMAL.** Only provide actionable feedback.
+
+**Skip all non-essential content:**
+- Do not generate "Pull request overview" sections
+- Do not create "Changes:" lists describing what was changed  
+- Do not create "Reviewed changes" sections or tables
+- Do not list files with change descriptions
+- Do not count how many files were reviewed
+- Do not summarize what the PR does (visible in the diff)
+
+**Focus only on problems:**
+- Comment ONLY on actual issues that need fixing
+- Keep each comment 1-3 sentences
+- If everything is correct, provide no output
+
+**Bad example (from PR 65578):**
+```
+## Pull request overview
+This PR addresses issue 65331 by replacing em dash characters...
+
+### Reviewed changes
+Copilot reviewed 4 out of 4 changed files...
+
+| File | Description |
+| ---- | ----------- |
+| file1.md | Updated em dash in seed content |
+```
+
+**Good example (actionable feedback only):**
+```
+Line 46: Test will fail - `innerText` returns rendered `—`, not `—`.
+```

 1. **Test Coverage** - Ensuring adequate testing for code changes
 2. **Pull Request Guidelines** - Compliance with contribution standards

 ## General Guidelines
 
-### Avoid
+**Focus on Actionable Issues Only**
 
-- Long explanations
-- Generic comments without specific pointers
-- Comments on non-functional changes
-- Repeating information already in the PR discussion
-- Commenting on the same issue multiple times
+### Strict Rules
+
+- NO summaries, overviews, or descriptions of changes
+- NO tables or file listings
+- NO "LGTM" or affirmative comments when everything is fine
+- Only comment when action is required
+- Keep each comment brief and actionable
 
 ### Prioritization
 
-When multiple issues exist, prioritize feedback in this order:
+When multiple issues exist, address them in order of severity:
 
-1. PR title/description compliance (most visible, easiest to fix)
+1. Security vulnerabilities or critical bugs
 2. Missing test coverage for new functionality
 3. Outdated tests for modified functionality
+4. PR title/description compliance
+
+Comment on all legitimate issues, but keep each comment concise.
