Renovate PR Review Results

⚖️ Safety Assessment: ✅ Safe

🔍 Release Content Analysis

v2.4.0 → v2.6.2 Changes:

• New Linters Added: godoclint, unqueryvet, iotamixing, modernize analyzer suite
• Enhanced Linter Features: Multiple existing linters received new options and improved functionality (e.g., exhaustruct, embeddedstructfieldcheck, gofumpt, revive)
• Bug Fixes: Numerous stability improvements across linters including gosec, fatcontext, testifylint, and others
• Go Version Support: Added support for Go 1.25 (already used in this project)
• No Breaking Changes: All updates maintain backward compatibility with existing configurations

Security Considerations:

• gosec linter updated from 2.22.7 → 2.22.10 with security improvements
• No security vulnerabilities reported in the changelog
• All changes are incremental improvements rather than major architectural changes

🎯 Impact Scope Investigation

Usage Analysis:

• Tool Installation: golangci-lint is managed via mise.toml (version update: 2.4.0 → 2.6.2)
• CI Integration: Used in .github/workflows/ci.yml:55 with command golangci-lint run --verbose ./...
• No Custom Configuration: Project uses default golangci-lint settings (no .golangci.yml found)
• Environment Setup: CI uses mise-action to install tools, which will automatically pick up the new version

Dependency Impact:

• No direct Go module dependencies affected (golangci-lint is a standalone tool)
• Current Go version (1.25.4) is fully supported by new golangci-lint version
• No changes required to existing Go code or project structure

💡 Recommended Actions

Immediate Actions:

• ✅ Safe to merge - No breaking changes or compatibility issues identified
• The upgrade is purely additive with bug fixes and new linter capabilities
• CI pipeline will continue to work without modifications

Optional Follow-up Actions:

• Consider reviewing new linters (godoclint, unqueryvet, iotamixing, modernize) to evaluate if they would benefit the project
• Update CLAUDE.md documentation which still references "golangci-lint 2.1.6" in the project instructions

Post-merge Validation:

• Monitor CI pipeline for any unexpected linter warnings from enhanced rules
• No code changes expected, but new linters might surface previously undetected code quality issues
