      ## Phase 1: Fetch Changes

      ### 1.1 Identify What to Review

      ```powershell
      # Uncommitted changes
      git diff

      # Specific branch vs main
      git diff main..HEAD

      # Specific commit range
      git diff commit1..commit2

      # Specific files
      git diff --name-only
      ```

      ### 1.2 Get Change Statistics

      ```powershell
      # Summary of changes
      git diff --stat

      # List changed files
      git diff --name-only

      # Check for binary files
      git diff --numstat
      ```

      ## Phase 2: Analyze Changes

      ### 2.1 Read Changed Files

      For each changed file:

      ```powershell
      # Read the full file (not just diff)
      read_file src/changed-file.ts

      # Check file history
      git log --oneline -5 -- src/changed-file.ts

      # Check who wrote original code
      git blame -L 40,50 src/changed-file.ts
      ```

      ### 2.2 Understand Context

      - Why was this change made?
      - What problem does it solve?
      - Are there related changes elsewhere?

      ## Phase 3: Evaluate Code

      ### 3.1 Confidence Thresholds

      Only flag issues where you have high confidence:

      | Severity | Confidence | Examples |
      |----------|------------|----------|
      | **CRITICAL** | 95%+ | Security vulnerabilities, data loss, crashes, auth bypasses |
      | **WARNING** | 85%+ | Bugs, logic errors, performance issues, unhandled errors |
      | **SUGGESTION** | 75%+ | Code quality, best practices, maintainability |
      | **Below 75%** | — | Don't comment — gather more context first |

      ## Phase 4: Report Findings

      ### 4.1 Summary

      2-3 sentences describing:
      - What the change does
      - Overall assessment (major concerns / looks good / excellent)

      ### 4.2 Issues Table

      | Severity | File:Line | Issue |
      |----------|-----------|-------|
      | CRITICAL | `src/auth.ts:42` | SQL injection vulnerability |
      | WARNING | `src/api.ts:78` | Unhandled promise rejection |
      | SUGGESTION | `src/utils.ts:15` | Function too long (150 lines) |

      ### 4.3 Detailed Findings

      For each issue:

      ```markdown
      ### Issue 1: [Brief Title]

      **File:** `path/to/file.ts:line`

      **Severity:** [CRITICAL/WARNING/SUGGESTION]

      **Confidence:** X%

      **Problem:**
      [What's wrong and why it matters]

      **Current Code:**
      ```typescript
      // Problematic code
      ```

      **Suggestion:**
      ```typescript
      // Recommended fix
      ```
      ```

      ### 4.4 Recommendation

      One of:
      - **APPROVE** — No significant issues
      - **APPROVE WITH SUGGESTIONS** — Minor improvements suggested
      - **NEEDS CHANGES** — Issues must be addressed
      - **NEEDS DISCUSSION** — Unclear if issues are real, need to talk

      ## Example Review

      ### Summary

      This PR adds user authentication with JWT tokens. Overall the approach is sound, but there are two security issues that need addressing before merge.

      ### Issues Found

      | Severity | File:Line | Issue |
      |----------|-----------|-------|
      | CRITICAL | `src/auth.ts:42` | JWT secret hardcoded |
      | WARNING | `src/middleware.ts:23` | No token expiration check |
      | SUGGESTION | `src/utils.ts:15` | Extract validation to shared function |

      ### Detailed Findings

      #### Issue 1: Hardcoded JWT Secret

      **File:** `src/auth.ts:42`

      **Severity:** CRITICAL

      **Confidence:** 99%

      **Problem:**
      The JWT secret is hardcoded in the source. This is a security vulnerability as anyone with code access can forge tokens.

      **Current Code:**
      ```typescript
      const token = jwt.sign(payload, 'my-secret-key')  // ❌ Hardcoded
      ```

      **Suggestion:**
      ```typescript
      const token = jwt.sign(payload, process.env.JWT_SECRET)  // ✅ From env
      ```

      **Required Action:**
      - Move secret to environment variable
      - Add validation that secret exists at startup
      - Rotate the exposed secret immediately

      #### Issue 2: Missing Expiration Check

      **File:** `src/middleware.ts:23`

      **Severity:** WARNING

      **Confidence:** 90%

      **Problem:**
      The middleware verifies the token signature but doesn't check if it has expired.

      **Current Code:**
      ```typescript
      jwt.verify(token, secret)  // ❌ No expiration check
      ```

      **Suggestion:**
      ```typescript
      jwt.verify(token, secret, { clockTolerance: 30 })  // ✅ Checks exp
      ```

      ### Recommendation

      **NEEDS CHANGES**

      The hardcoded secret is a blocker. Please address the CRITICAL issue before merging. The WARNING should also be fixed. The SUGGESTION is optional.

      - [ ] Read all changed files
      - [ ] Understood context and purpose
      - [ ] Checked for security issues
      - [ ] Checked for bugs and logic errors

      - [ ] Provided clear recommendations
      - [ ] Explained reasoning for issues

      ## Best Practices

      1. **Be constructive** — Suggest improvements, don't just criticize
      2. **Explain why** — Help the author learn
      3. **Prioritize** — Focus on issues that matter
      4. **Acknowledge good work** — Positive feedback is valuable
      5. **Stay objective** — Code quality, not personal preference
      6. **Be thorough** — Don't rubber-stamp
      7. **Be specific** — Point to exact lines and suggest fixes
      8. **Consider context** — Match review to change size
      9. **Follow up** — Verify fixes if requested
      10. **Stay humble** — You might be wrong, be open to discussion

      ## Tone Guidelines

      ### Constructive

      ✅ "Consider extracting this into a separate function for better testability"
      ❌ "This is messy"

      ✅ "This could be a security risk because..."
      ❌ "This is insecure"

      ✅ "For consistency with the rest of the codebase..."
      ❌ "We don't do it this way"

      ### Educational

      Explain the "why" behind suggestions:

      > "Using `useCallback` here prevents unnecessary re-renders of child components that depend on this function reference."

      ### Balanced

      Acknowledge what's good:

      > "Great use of early returns here — makes the logic much clearer. One small suggestion..."
