-          WORKFLOW:
-            1. Setup GitHub authentication (CRITICAL - DO THIS FIRST!)
+          SETUP:
+            1. GitHub authentication (DO THIS FIRST):
                export GH_TOKEN=\$(coder external-auth access-token github)
                export GITHUB_TOKEN="\${GH_TOKEN}"
 
-               # Verify authentication works
-               if ! gh auth status; then
-                 echo "ERROR: GitHub authentication failed"
-                 echo "Please ensure GitHub external auth is configured in Coder"
-                 exit 1
-               fi
+               # Verify it works
+               gh auth status || { echo "ERROR: GitHub auth failed"; exit 1; }
 
-               echo "✅ GitHub authentication successful"
-
-            2. Setup repository (repo is pre-cloned at ~/coder)
+            2. Checkout the PR:
                cd ~/coder
                git fetch origin pull/${PR_NUMBER}/head:pr-${PR_NUMBER}
                git checkout pr-${PR_NUMBER}
 
-            3. Get PR info
-               Use GitHub MCP tools to get PR title, body, and full diff
-               Or use: git diff main...pr-${PR_NUMBER}
-               Note: GH_TOKEN is now configured for gh CLI
-
-            4. PHASE 1: Read and Understand (DO NOT comment yet)
-               REMEMBER: It's perfectly valid to find 0 issues!
-               a) Read the entire PR diff carefully
-               b) Understand the PR's purpose and scope
-               c) Note areas of concern for further analysis
-               d) DO NOT start writing comments yet
-
-            5. PHASE 2: Analyze Each Potential Issue (Question-based)
-               For each area of concern, ask yourself:
-
-               BEFORE commenting, verify:
-               Q: "Is this code actually incorrect or could it cause problems?"
-                  → If no, skip it
-               Q: "Does my suggested fix actually differ from the current code?"
-                  → If no, skip it
-               Q: "Would this issue impact functionality, security, or maintainability?"
-                  → If no, probably skip it
-               Q: "Is this consistent with Coder codebase patterns?"
-                  → Check similar code in the repo first
-
-               Focus on:
-               - Security vulnerabilities (auth, injection, secrets)
-               - Logic bugs that cause incorrect behavior
-               - Missing error handling for failure cases
-               - Performance issues (N+1 queries, unbounded loops)
-               - Missing tests for new functionality
-               - Style that conflicts with existing patterns
-
-            6. PHASE 3: Build Review (Only real issues)
-               Create comments ONLY for issues that passed Phase 2 questions
-               Each comment should:
-               - Explain WHAT is wrong and WHY it matters
-               - Provide a concrete, different fix in \`\`\`suggestion block
-               - Be brief and actionable
-
-               IMPORTANT: If you find 0 issues, that's valid! Don't invent problems.
-
-            7. PHASE 4: Self-Critique Before Submitting
-               Review YOUR comments:
-               - Remove any where suggested code == current code
-               - Remove trivial style nitpicks
-               - Remove vague or obvious comments
-               - Quality over quantity - 0 real issues is better than 1 false positive
-
-            8. Submit ONE review with ALL inline comments via GitHub API
-
-          HOW TO POST A REVIEW WITH INLINE COMMENTS (SIMPLIFIED):
-
-            IMPORTANT: You have access to gh CLI with GH_TOKEN already configured.
-
-            SIMPLE METHOD - Use JSON file:
-
-            Step 1: Get the PR commit SHA
+            3. Get the full diff:
+               git diff main...pr-${PR_NUMBER}
+
+          REVIEW PROCESS:
+            1. Read the entire PR diff and understand what it does
+            2. Identify real issues (security bugs, logic errors, missing error handling)
+            3. For each issue, verify:
+               - Is it actually wrong or problematic?
+               - Would fixing it change the code?
+               - Does it impact functionality, security, or maintainability?
+            4. Submit ONE review with inline comments for issues found
+
+            IMPORTANT: Finding 0 issues is valid - don't invent problems.
+
+          WHAT TO FOCUS ON (priority order):
+            1. Security issues (auth, injection, secrets exposure)
+            2. Logic bugs and incorrect behavior
+            3. Missing error handling for failure cases
+            4. Performance problems (N+1 queries, unbounded loops)
+            5. Missing tests for new functionality
+            6. Style issues that conflict with existing Coder patterns
+
+          HOW TO SUBMIT THE REVIEW:
+
+            Step 1: Get commit SHA
             COMMIT_SHA="\$(gh api repos/${REPO_OWNER}/${REPO_NAME}/pulls/${PR_NUMBER} --jq '.head.sha')"
 
-            Step 2: Create a JSON file with your review
+            Step 2: Create review.json with your findings
             cat > review.json <<'REVIEW_EOF'

               ]
             }
             REVIEW_EOF
 
-            Step 3: Replace the commit SHA in the JSON
-            sed -i "s/PUT_COMMIT_SHA_HERE/\${COMMIT_SHA}/" review.json
+            Step 3: Replace SHA and submit
+            sed -i "s/PUT_SHA_HERE/\${COMMIT_SHA}/" review.json
+            gh api repos/${REPO_OWNER}/${REPO_NAME}/pulls/${PR_NUMBER}/reviews --method POST --input review.json
 
-            Step 4: Submit the review with one simple command
-            gh api repos/${REPO_OWNER}/${REPO_NAME}/pulls/${PR_NUMBER}/reviews \\
-              --method POST \\
-              --input review.json
-
-            IMPORTANT NOTES:
-            - Use JSON for cleaner, easier-to-read review structure
-            - "side" should be "RIGHT" for the new/changed code
-            - "event" can be "COMMENT", "APPROVE", or "REQUEST_CHANGES"
-            - For this task, use "COMMENT" (neutral feedback with suggestions)
-            - Line numbers are integers (no quotes needed in JSON)
-            - Use \\n for newlines in JSON strings
+          INLINE COMMENT FORMAT:
+            - path: relative path from repo root (no leading /)
+            - line: line number (integer)
+            - side: "RIGHT" (for new/changed code)
+            - body: Issue description + suggestion block
 
           GITHUB SUGGESTION SYNTAX:
-            GitHub renders \`\`\`suggestion blocks as one-click committable suggestions.
-            The suggestion replaces the line(s) it comments on.
+            Use \`\`\`suggestion (NOT \`\`\`go or other language tag)
+            Include only the corrected lines with exact indentation
+            GitHub will show a one-click "Commit suggestion" button
 
-            Example inline comment body:
-            **Issue:** Error not wrapped with context. Makes debugging harder.
+            Example:
+            **Issue:** Missing error context makes debugging harder.

             \`\`\`
 
-          WORKFLOW:
-            1. Read the PR diff and analyze all changes
-            2. Build a list of ALL issues with their file path, line number, and suggested fix
-            3. Submit ONE review with ALL inline comments at once
-            4. Include a summary body in the review
-
-          SUMMARY COMMENT FORMAT:
-          ## 🔍 Code Review
-
-          [1-2 sentences: what does this PR do?]
-
-          **Found:** X critical, Y important, Z minor issues
-          [If 0 issues: **Looks good** - no issues found]
-          [Optional 1-liner: Notable strength or concern]
-
-          [If issues: "See inline comments for details."]

-
-          Keep it SHORT - aim for 8-12 lines total, skip fluff
-
-          CRITICAL REQUIREMENTS:
-            1. Post inline comments on SPECIFIC LINES where issues exist
-            2. Use \`\`\`suggestion syntax for every code change
-            3. Each suggestion must be committable with one click
-            4. Only include the lines that need to change in the suggestion block
-            5. Make sure suggestion syntax is exactly: \`\`\`suggestion (no language tag)
-            6. Post summary comment after all inline comments are done
-
-          INLINE COMMENT STRUCTURE:
-            {
-              "path": "path/to/file.go",
-              "line": 123,
-              "side": "RIGHT",
-              "body": "**Issue:** [What's wrong and why it matters]\n\n\`\`\`suggestion\n[Fixed code that differs from original]\n\`\`\`"
-            }
-
-            Example of good comment:
-            "**Issue:** Error not wrapped - makes debugging production issues difficult.\n\n\`\`\`suggestion\nreturn xerrors.Errorf(\"fetch user: %w\", err)\n\`\`\`"
-
-            Build incrementally:
-            - Start with empty comments array
-            - Add issues that pass Phase 2 questions
-            - Review and prune before submitting
-            - If comments array is empty (no issues), that's OK! Submit review with just summary
-
-          SUGGESTION BLOCK RULES:
-            - Use \`\`\`suggestion (not \`\`\`go or any other language)
-            - Include ONLY the corrected lines
-            - Preserve exact indentation from the original file
-            - GitHub will replace the commented line(s) with your suggestion
-            - For single-line suggestions: comment on that line
-            - For multi-line suggestions: use start_line and line parameters
-              Example: -F 'comments[][start_line]=10' -F 'comments[][line]=15'
-              This comments on lines 10-15 and your suggestion replaces all of them
-            - Always use side="RIGHT" to comment on the PR changes
-
-          REVIEW PRINCIPLES:
-
-            Priority Order (focus on impact):
-            1. Security issues (authentication, authorization, injection, secrets)
-            2. Functional bugs (incorrect logic, missing error handling)
-            3. Performance problems (N+1 queries, memory leaks, unbounded operations)
-            4. Missing tests for new behavior
-            5. Style issues that conflict with Coder patterns (Uber Go Style Guide)
-
-            Quality Guidelines:
-            - Question your assumptions - ask "Is this actually wrong?"
-            - Verify suggestions differ from current code
-            - Finding 0 issues is a valid outcome - don't force it
-            - Comment if it matters, skip if it doesn't
-            - Explain impact, not just what's wrong
-            - Better to approve good code than invent problems
-
-            Technical Notes:
-            - "\${VAR}" is properly quoted, don't suggest changes
-            - set -euo pipefail: only for scripts with conditionals/loops/API calls
-            - Match existing code patterns before suggesting style changes
-
-          SUBMISSION CHECKLIST:
-            Before submitting review.json:
-            □ Read through all comments once more
-            □ Verify each suggestion actually changes something
-            □ Confirm issues are real, not false positives
-            □ If 0 issues found, that's valid - don't force problems
-            □ Check JSON syntax: jq . review.json
-            □ Summary is concise (8-12 lines)
-            □ No language tags in \`\`\`suggestion blocks
-            □ Using event="COMMENT" not REQUEST_CHANGES
-
-          ERROR HANDLING:
-            Before submitting the review:
-            1. Check that GH_TOKEN is set: echo \$GH_TOKEN
-            2. Verify commit SHA is valid: echo \$COMMIT_SHA
-            3. Test API access: gh api user --jq '.login'
-
-            If gh api fails:
-            1. Check error message for specific issue
-            2. Verify file paths are relative to repo root (no leading /)
-            3. Ensure line numbers exist in the PR diff
-            4. Check that side="RIGHT" for changed code
-            5. As last resort, post a summary comment explaining the findings
+          QUALITY GUIDELINES:
+            - Only comment on real issues that matter
+            - Each suggestion must actually differ from current code
+            - Explain WHY it matters, not just WHAT is wrong
+            - Be specific and actionable
+            - Finding 0 issues is perfectly valid
+            - Match existing Coder codebase patterns (check similar code first)
+
+          TECHNICAL NOTES FOR SHELL SCRIPTS (.sh files):
+            - In bash scripts, \${VAR} is properly quoted - don't suggest changes
+            - set -euo pipefail is good practice for .sh files with conditionals/loops
+            - Don't apply bash-specific rules to YAML workflow files
+
+          IF NO ISSUES FOUND:
+            Submit a review with empty comments array and positive summary:
+            {"event": "COMMENT", "commit_id": "...", "body": "## 🔍 Code Review\n\n[Summary]\n\n**Looks good** - no issues found.\n\n---\n*AI review*", "comments": []}
