165. **Freshdesk Integration**: Update issues with structured review findings and log time entry
176. **Line-Specific Feedback**: Add comments directly on problematic code lines
18 
19## Input Data Analysis
20 
21- Pull GitHub PR URL from $ARGUMENTS.
22- If not provided during the prompt, ask user to provide PR number or URL, extract and analyse:
23 
24### Pull Request Context
25- **PR Details**: Extract PR number 
26- **Repository Info**: Note owner, repo name, and branch information
27- **Change Statistics**: Review additions, deletions, and changed files count
28- **Use GitHub mcp tool**: Use github-mcp tool to connect to GitHub. If fails, Use gh cli.
29 
30### Issue Context
31- **Requirements**: Parse issue description and conversations to understand functional requirements.
32  If issue description is missing, request user to provide it.
33- **Acceptance Criteria**: Identify specific acceptance criteria from issue conversations
34- **Client Feedback**: Review conversation history for clarification and changes
35- **Technical Context**: Note technology stack, modules affected, and dependencies
36- **Extract issue information**: Check PR description and title to pull issue number. 
37	In most cases it will be a Freshdesk issue. Use freshdesk-mcp task get issue information,
38	conversations and issue summary to understand context of the issue.
39 
40### Issue Context
41- **Requirements**: Parse issue description and conversations to understand functional requirements
42- **Acceptance Criteria**: Identify specific acceptance criteria from issue conversations
43- **Client Feedback**: Review conversation history for clarification and changes
44- **Technical Context**: Note technology stack, modules affected, and dependencies
45 
46### Site summary context
47- **Use atlassian-mcp tool**: to access confluence and find the Site Summary in the SUPPORT space.
48    The Site Summary would include production domain in page title. The Site Summary may have important
49    details with project customisations. Keep this page up to date when you identify inconsistencies,
50    or information is missing, based on your PR review outcome.
51 
52### Code Changes
53- **Files Modified**: Analyse changed files and their purposes
54- **Code Patterns**: Review implementation approach and architecture
55- **Security Implications**: Assess security impact of changes
56- **Important**: Note that this PR review tool is for ALL repositories (Drupal backend AND Vue.js/React frontends)
57 
58## Review Process
59 
60### 1. Requirement Analysis (Pass Score: 80%)
61Compare code changes against:
62- Original issue requirements

178### 3. Drupal-Specific Security Assessment
179**Native Drupal Security (Auto-Pass Criteria):**
180- CSRF protection is handled automatically by Drupal Form API - no manual checks needed
181- Administrative forms protected by permission system - inherently secure
182- Drupal's built-in input filtering and sanitisation - trust the framework
183- Entity access control through Drupal's entity system - framework handles this
184 
185**Manual Security Checks Required:**
186- Custom database queries must use parameterised queries
187- Direct HTML output must use proper sanitisation functions
188- File uploads must validate file types and permissions
189- Custom access callbacks must be properly implemented
190- Cache invalidation strategy must be secure
191- Update path testing for existing sites
192- Multisite compatibility verification
193- Queue/Batch API for scalability
194- Entity access checks beyond basic permissions
195 
196## Line-Specific Comments (CRITICAL)
197 
198**ALWAYS add line-specific comments** for identified issues using the GitHub review API:
199 
2001. **Use the review API** to create a review with line comments:
201```bash
202   # Create a JSON file with review comments
203   cat &gt; /tmp/review_comments.json &lt;&lt; 'EOF'
204   {
205     &quot;body&quot;: &quot;Code review with line-specific feedback&quot;,
206     &quot;event&quot;: &quot;REQUEST_CHANGES&quot;, # or "APPROVE" or "COMMENT"
207     &quot;comments&quot;: [
208       {
209         &quot;path&quot;: &quot;path/to/file.ext&quot;,
210         &quot;line&quot;: 123, # Line number in the diff
211         &quot;body&quot;: &quot;Your comment here with code suggestions&quot;
212       }
213     ]
214   }
215   EOF
216   
217   # Submit the review
218   gh api repos/{owner}/{repo}/pulls/{pr_number}/reviews -X POST --input /tmp/review_comments.json
219```
220 
2212. **Line comment best practices**:
222   - Be specific about the issue and provide the fix
223   - Include code snippets showing the correct implementation
224   - Reference relevant documentation or standards
225   - Use markdown formatting for clarity
226 
2273. **Common pitfalls to avoid**:
228   - Don't use `gh pr comment` for line-specific feedback (it only adds general comments)
229   - Don't try to use deprecated comment APIs
230   - Ensure line numbers match the diff view, not the file view
231 
232## Decision Criteria (Drupal-Context Aware)
233 
234- **Approve**: Overall score ≥ 80% AND requirement fulfilment ≥ 80% AND no critical custom security issues
235- **Request Changes**: Overall score < 75% OR requirement fulfilment < 80% OR critical custom security vulnerabilities
236- **Comment**: Score 75-79% with minor issues
237 
238**Note**: Drupal's native security features (Form API CSRF, permission-based access, Entity API) are considered secure by default and should not trigger failures.
239

307 
308**Label Application Methods:**
3091. **Preferred**: Use `gh issue edit` command (works for PRs too):
310```bash
311   gh issue edit {pr_number} --repo {owner}/{repo} --add-label &quot;label1&quot; --add-label &quot;label2&quot;
312```
3132. **Alternative**: If repository uses non-standard labels, check existing labels first:
314```bash
315   gh label list --repo {owner}/{repo} --limit 100
316```
317   Then apply the most appropriate existing labels
318 
319## Freshdesk Management
320 
321After completing the code review, perform the following Freshdesk updates:
322 
3231. **Add Private Note** with review findings using structured HTML format with appropriate colour coding

454- [ ] Configuration split for environments
455 
456## CRITICAL: Self-Improvement Protocol
457 
458**MANDATORY**: After EVERY code review session, you MUST update this command file (create if file does not exist. Filename `docs/pr.md` within project root) with:
459 
4601. **New Technology Stacks Encountered**:
461   - Add specific review criteria for any new frameworks/languages
462   - Document unique linting rules or standards
463   - Note build/test commands specific to that stack
464 
4652. **Command Issues and Workarounds**:
466   - Document any gh CLI commands that failed and why
467   - Add working alternatives you discovered
468   - Update examples with real, tested commands
469 
4703. **Repository-Specific Patterns**:
471   - Custom label schemes used by specific organisations
472   - Unique workflow requirements
473   - Special security or compliance needs
474 
4754. **Review Process Improvements**:
476   - Better ways to extract requirements from issues
477   - More efficient review workflows
478   - Time-saving automation opportunities
479 
4805. **Common Code Issues by Technology**:
481   - Add to the "Commonly Missed" sections
482   - Create new sections for technology-specific pitfalls
483   - Update scoring criteria based on real reviews
484 
485### Update Process:
4861. At the end of each review, ask yourself: "What did I learn?"
4872. Use the `Edit` tool to update relevant sections
4883. Add real examples from the review you just completed
4894. Test any new commands before documenting them
490 
491### Example Update Entry:
492```markdown
493### [Date] - Technology: [Stack] - Repository: [Name]
494**Issue**: [What happened]
495**Solution**: [How you solved it]
496**Future Prevention**: [What to do next time]
497```
498 
499## Lessons Learned from Review Sessions
500 
501### What Works Well:
5021. **gh CLI**: Reliable for PR operations
5032. **gh issue edit**: Works for adding labels to PRs (PRs are issues in GitHub)
5043. **Review API**: Best method for line-specific comments
5054. **JSON input files**: Clean way to structure complex review data
506 
507### Common Pitfalls:
5081. **Don't assume Drupal**: Many repos are Vue.js/React frontends
5092. **Check existing labels**: Repos may have custom label schemes
5103. **Line comments require review API**: `gh pr comment` only adds general comments
5114. **No issue reference**: Not all PRs reference issues - proceed with code review anyway
5125. **Import statements**: Watch for incorrect ES6 module imports in frontend code
5136. **Deprecated Vue features**: `/deep/` selector, unused props, etc.
514 
515### Technology-Specific Discoveries:
516 
517#### Vue.js (Vue 2)
518- **Date**: 2025-06-03
519- **Issue**: `/deep/` selector still being used
520- **Solution**: Always flag for `::v-deep` replacement
521- **Common Pattern**: Unused props passed but never utilized
522 
523#### GitHub API Quirks
524- **Date**: 2025-06-03
525- **Issue**: `gh pr edit --add-label` fails with permissions error
526- **Solution**: Use `gh issue edit` instead (PRs are issues)
527- **Note**: Some repos have 100+ custom labels - always check first
528
