# Session Handover: Issue #1225 - SonarCloud String Method Modernization **Date**: October 2, 2025 **Current State**: Ready for implementation **Previous Work**: Issues #1231 and #1223 completed and merged ## Quick Start ```bash # 1. Navigate to repository cd /Users/mick/Developer/Organizations/DollhouseMCP/active/mcp-server # 2. Ensure on develop branch git checkout develop && git pull # 3. Activate SonarCloud elements # Use these MCP commands to activate: mcp__dollhousemcp-production__activate_element --name sonar-guardian --type personas mcp__dollhousemcp-production__activate_element --name sonarcloud-modernizer --type skills mcp__dollhousemcp-production__activate_element --name sonarcloud-hotspot-marker --type skills ``` ## Context: What's Been Done ### Recent Completions (October 1-2, 2025) - ✅ **Issue #1231 / PR #1232**: Removed temporary SonarCloud utility scripts (merged) - ✅ **Issue #1223 / PR #1233**: Fixed 15 Array constructor instances (merged) - ✅ **Issue #1224 / PR #1227**: Fixed 4 MEDIUM severity issues (merged October 1) ### SonarCloud Progress - **Total issues resolved**: 243+ issues (from 262 down to ~19 remaining) - **Security hotspots**: All 199 evaluated and marked SAFE - **Current status**: LOW priority cleanup remaining ## Your Mission: Issue #1225 ### Issue Details - **Title**: [SonarCloud] Fix S7758 - String method modernization (6 issues) - **Rule**: typescript:S7758 - **Count**: 6 issues - **Severity**: LOW reliability impact - **Type**: CODE_SMELL - **Estimated Time**: 30 minutes (with 50% buffer = 45 minutes) ### What S7758 Covers String method modernization, likely including: - `String.fromCharCode()` → `String.fromCodePoint()` (Unicode-aware) - `str.charCodeAt()` → `str.codePointAt()` (Unicode-aware) - Other modern string method improvements ### Why This Matters - **Final cleanup**: This achieves ZERO reliability issues! 🎉 - **Unicode correctness**: Modern methods handle Unicode properly - **Code quality**: Follows modern JavaScript/TypeScript best practices ## Step-by-Step Process ### Step 1: Query SonarCloud for S7758 Issues **CRITICAL**: Use the correct query procedure from `docs/development/SONARCLOUD_QUERY_PROCEDURE.md` ```bash # Get SonarCloud token SONAR_TOKEN=$(security find-generic-password -s "sonar_token2" -w) # Query for S7758 issues on main branch curl -s -H "Authorization: Bearer $SONAR_TOKEN" \ "https://sonarcloud.io/api/issues/search?projects=DollhouseMCP_mcp-server&branch=main&rules=typescript:S7758&ps=500" \ > /tmp/s7758-issues.json # View issue count and locations jq '.total, (.issues | length)' /tmp/s7758-issues.json jq -r '.issues[] | "\(.component | sub(".*:"; "")):\(.line) - \(.message)"' /tmp/s7758-issues.json ``` ### Step 2: Create Feature Branch ```bash # Ensure on develop git checkout develop && git pull # Create feature branch following naming convention git checkout -b feature/sonarcloud-issue-1225-string-methods # Verify branch git branch --show-current ``` ### Step 3: Analyze and Fix Each Instance For each issue location: 1. **Read the file** at the specific line number 2. **Understand the context** - what is the code doing? 3. **Evaluate the fix**: - Is it safe to change `fromCharCode` to `fromCodePoint`? - Is it safe to change `charCodeAt` to `codePointAt`? - Will this affect Unicode handling? 4. **Apply the fix** using Edit tool 5. **Document why** in code comments if needed **Example Pattern**: ```typescript // Before (S7758 violation) const char = String.fromCharCode(0x1F600); // After (S7758 compliant) const char = String.fromCodePoint(0x1F600); ``` ### Step 4: Verify Changes ```bash # Build must succeed npm run build # Tests must pass npm test -- --no-coverage # Check for unintended changes git diff # Expected: 6 files changed, clean test results ``` ### Step 5: Commit and Push ```bash # Stage changes git add <changed-files> # Commit with proper message format git commit -m "$(cat <<'EOF' fix(sonarcloud): [S7758] String method modernization (6 issues) - Replaced String.fromCharCode with String.fromCodePoint (X instances) - Replaced str.charCodeAt with str.codePointAt (Y instances) - Files affected: [list main files] - SonarCloud impact: -6 reliability issues (ZERO remaining!)

Should I proceed with all 6 fixes, or review each one first? 2. Any specific files I should be careful with? 3. Do you want to review the query results before I start fixing? ## Time Estimate - Query SonarCloud: 2 minutes - Analyze 6 instances: 10 minutes - Apply fixes: 10 minutes - Testing: 5 minutes - Commit/PR: 5 minutes - **Total**: ~32 minutes - **With buffer**: ~45 minutes ## Contact/Escalation If you encounter: - **Broken MCP tools**: Use curl workarounds (documented in sonarcloud-api-reference) - **Test failures**: Check if they're pre-existing (GitHubRateLimiter issue #1165) - **Unclear fixes**: Ask user for guidance on specific instance - **CI failures**: Check which step failed, may need iteration ## Final Checklist Before declaring complete: - [ ] All 6 S7758 instances addressed - [ ] Build passes locally - [ ] Tests pass locally (npm test) - [ ] PR created with proper format - [ ] CI checks all green - [ ] Issue #1225 referenced in PR - [ ] User notified PR is ready for merge --- **Remember**: This is the final reliability issue cleanup. After this, we achieve ZERO reliability issues on SonarCloud! 🎉 **Previous successful patterns**: See PR #1232 and PR #1233 for reference on commit messages, PR format, and workflow. **Key personas active**: sonar-guardian (for guidance), sonarcloud-modernizer (for automation patterns) Good luck! 🚀
