PR Review: Remove bundler/gem_tasks to fix release task conflict

Summary

This PR successfully addresses a real issue where bundler/gem_tasks was creating a duplicate release task that conflicted with the custom release workflow in rakelib/release.rake. The solution is clean and follows the established pattern used in react_on_rails.

Code Quality and Best Practices

Strengths:

• Clear, focused change that solves a specific problem
• Good code comments explaining the rationale (Rakefile:6-7)
• Follows the existing pattern from react_on_rails gem
• Maintains backward compatibility by preserving the :build task functionality

Suggestions:

1. Error handling in build task (Rakefile:9-14): Consider adding cleanup of existing gem files before building and using FileUtils.mv instead of sh mv for better error handling
2. Documentation alignment: The RELEASING.md mentions rake release:prepare and rake release:publish tasks, but rakelib/release.rake only defines a single rake release task. This discrepancy should be addressed.

Potential Issues

1. Critical: Documentation mismatch - RELEASING.md describes a two-step release process (release:prepare and release:publish), but the code only shows a single release task in rakelib/release.rake:27. This could confuse maintainers.

2. Build task robustness:

   • No cleanup of existing gem files before building (could cause issues if VERSION changes)
   • Uses sh with string interpolation instead of more robust Ruby file operations
   • No verification that the gem file was actually created before moving it

3. Version constant loading: The build task uses require_relative to load the version (Rakefile:10). This is fine, but be aware it loads the entire module.

Performance Considerations

No significant performance concerns. The changes are minimal and only affect rake task execution, which is already a relatively slow operation. The custom :build task should perform similarly to the bundler version.

Security Concerns

Low risk overall, but worth noting:

1. Command injection risk (minor): The build task uses sh with string interpolation containing CypressOnRails::VERSION (Rakefile:13). While VERSION is defined in code (not user input), consider using FileUtils instead of sh mv for defense-in-depth.

2. File system operations: Creating directories and moving files without validation could theoretically be exploited if VERSION is ever compromised, though this is very unlikely.

Test Coverage

Missing test coverage:

• No tests for the new :build task
• No integration test verifying only one release task exists
• The PR test plan checklist is incomplete (unchecked boxes)

Recommendations:

1. Add a spec to verify the build task works correctly
2. Add a spec to ensure rake -T release shows only one release task
3. Consider adding a test that the built gem can be installed successfully
4. Complete the test plan checklist before merging

Approval Recommendation

Approve with minor revisions. The core change is solid and solves the immediate problem. However, I recommend addressing these items before or shortly after merging:

Before merging:

1. Resolve the RELEASING.md documentation mismatch
2. Complete the test plan checklist manually to verify the changes work

Follow-up improvements (can be separate PR):
3. Add test coverage for rake tasks
4. Improve build task robustness with FileUtils and error handling
5. Verify the release workflow end-to-end matches documentation

Additional Notes

• The choice to remove bundler/gem_tasks is correct given the conflict
• This aligns well with how react_on_rails handles releases
• The commit message is clear and well-formatted
• Good use of heredoc in release.rake:49 for multi-line messages

Great work on identifying and fixing this task conflict!

Code Review for PR #191: Remove bundler/gem_tasks to fix release task conflict

✅ Strengths

1. Clear Problem & Solution: The PR correctly identifies and fixes the duplicate task definition conflict between bundler/gem_tasks and the custom release task.

2. Consistent Pattern: Removing bundler/gem_tasks aligns with the react_on_rails pattern mentioned in the PR description, creating consistency across ShakaCode gems.

3. Good Documentation: The inline comments in Rakefile:6-7 clearly explain why bundler/gem_tasks was removed.

4. Minimal Change: The PR is focused and makes only the necessary changes to resolve the issue.

⚠️ Issues & Recommendations

1. CRITICAL: Mismatch with RELEASING.md Documentation

The RELEASING.md file extensively references release:prepare and release:publish tasks (lines 21, 23, 31, 56, 99, 102, 105, 110, 166, 198, 213), but the actual implementation in rakelib/release.rake only provides a single release task. This creates a significant documentation/implementation mismatch.

Recommendation: Either:

• Update RELEASING.md to match the actual single-task implementation, OR
• Add the release:prepare and release:publish tasks that the documentation describes

2. Potential Issue: Build Task Error Handling

In Rakefile:9-14, the new :build task has a potential issue:

task :build do
  require_relative "lib/cypress_on_rails/version"
  sh "gem build cypress-on-rails.gemspec"
  sh "mkdir -p pkg"
  sh "mv cypress-on-rails-#{CypressOnRails::VERSION}.gem pkg/"
end

Problem: If the gem build fails, the subsequent mv command will still attempt to run and fail with a confusing error message.

Recommendation: Add error handling or combine commands:

task :build do
  require_relative "lib/cypress_on_rails/version"
  sh "mkdir -p pkg"
  sh "gem build cypress-on-rails.gemspec && mv cypress-on-rails-#{CypressOnRails::VERSION}.gem pkg/"
end

3. Missing: pkg/.gitignore Entry

The :build task creates a pkg/ directory. Verify that pkg/ is in .gitignore to prevent accidentally committing built gems.

Action: Check if pkg/ is in .gitignore, add if missing.

4. Minor: Comment Typo in release.rake

Line 18 in rakelib/release.rake has a minor wording change from "ruby gem" to "(ruby gem)" - this is fine but consider consistency.

🧪 Test Coverage Concerns

The PR test plan mentions:

• rake -T release shows only one release task
• rake release[1.19.0] correctly updates version
• rake build still works

Recommendation: These should be verified in CI or manually before merging. Consider adding a rake task spec to prevent future regressions.

🔒 Security

No security concerns identified. The changes are limited to build tooling.

⚡ Performance

No performance impact. Build tasks are development-only.

📋 Suggested Actions Before Merge

1. High Priority: Resolve the RELEASING.md documentation mismatch
2. Medium Priority: Add error handling to the :build task
3. Low Priority: Verify pkg/ is in .gitignore
4. Low Priority: Test the three items in the test plan

Summary

The core fix is sound and solves the duplicate task problem. However, the documentation discrepancy with RELEASING.md needs to be addressed before merging, as it will confuse users trying to release new versions.

Review completed by Claude Code

PR Review: Remove bundler/gem_tasks to fix release task conflict

Overall Assessment

This is a well-thought-out PR that properly addresses a real conflict in the Rake task setup. The changes are clean, focused, and include good documentation.

Code Quality & Best Practices

Strengths:

• Clear separation of concerns - manually implementing build task to avoid bundler/gem_tasks conflicts
• Good inline comments explaining the reasoning (Rakefile:6-7)
• Follows the established pattern from react_on_rails as noted in the PR description

Suggestions:

1. Error handling in build task (Rakefile:9-14)

   • Consider adding error handling if the gem build fails
   • The mkdir -p is good, but the mv command could fail if the build did not produce a gem

2. Missing newline at EOF (rakelib/task_helpers.rb:23)

   • The file is missing a final newline, which most Ruby style guides recommend

Potential Issues

Medium Priority:

1. sh_in_dir behavior change (rakelib/task_helpers.rb:11-21)

   • The refactor from inline shell execution to Dir.chdir changes the working directory for the entire block
   • This is generally better, but make sure all existing callers do not rely on the previous behavior
   • The addition of Bundler.with_unbundled_env is excellent and necessary, but this is a significant behavioral change that should be tested

2. Version file specificity (rakelib/release.rake:43)

   • Adding --file lib/cypress_on_rails/version.rb is more explicit, which is good
   • However, ensure gem bump from gem-release supports this flag (it should, but worth verifying)

Performance Considerations

No performance concerns. The changes are all build/release-time operations, not runtime code.

Security Concerns

Low Priority:

1. Shell injection potential (rakelib/task_helpers.rb:17)
   • The sh(shell_command.strip) does not escape or validate input
   • Since this is only used in controlled rake tasks with trusted input, risk is minimal
   • However, if gem_version from user input contained malicious characters, it could be an issue
   • Consider validating version format: /\A\d+.\d+.\d+\z/

Test Coverage

Gaps Identified:

The PR description includes a test plan, but:

• No automated tests added for the new build task
• No tests verifying the sh_in_dir refactor does not break existing functionality
• The checklist in the PR description should be completed before merge

Recommendations:

1. Add a spec for the build task to verify it creates the gem in pkg/
2. Test the release task with a dry run to ensure version bumping works correctly
3. Verify that Bundler.with_unbundled_env does not cause issues in the release workflow

Additional Notes

1. Documentation: Consider updating RELEASING.md if it exists to document the new workflow
2. Consistency: The change from inline cd to Dir.chdir is an improvement - good work!
3. The test plan items should be verified before merging

Recommendation

Approve with minor changes:

• Add newline at EOF in task_helpers.rb
• Verify test plan items are completed
• Consider adding version format validation
• Consider error handling in build task

The core changes are solid and solve the stated problem effectively. Nice work!

Pull Request Review

Summary

This PR successfully addresses the duplicate release task issue and introduces comprehensive code quality improvements through RuboCop integration and automated linting.

✅ Strengths

1. Core Issue Resolution

• Problem correctly identified: Removing require 'bundler/gem_tasks' from Rakefile eliminates the duplicate release task conflict
• Clean solution: The custom release task in rakelib/release.rake now works without conflicts
• Well documented: The PR description clearly explains the problem and solution

2. Code Quality Improvements

• RuboCop configuration: Well-structured .rubocop.yml with sensible defaults
  • Appropriate line length (120 chars)
  • Enforces single quotes for consistency
  • Frozen string literal comments for performance
  • Proper exclusions for specs and generated code
• Comprehensive formatting fixes: All files now follow consistent Ruby style
  • Single quotes throughout
  • Frozen string literal pragmas
  • Proper trailing newlines
  • Clean indentation

3. Developer Experience

• Pre-commit hook (bin/install-hooks): Prevents code quality issues before commit
• CI integration (.github/workflows/lint.yml): Automated linting on PRs
• Helpful rake tasks: rake lint, rake lint:fix, rake check_newlines, rake fix_newlines

4. Test Coverage

• All spec files updated with consistent formatting
• No test logic changed, maintaining existing coverage

🔍 Observations & Minor Concerns

1. Missing Build Task (Priority: Medium)

The Rakefile removes require 'bundler/gem_tasks' but I don't see where the :build task is defined. The old Rakefile had:

task default: %w[spec build]

The new version has:

task default: :ci

Question: Where is the build task now defined? The PR description mentions "Added manual :build task" but I don't see it in the diff. The release.rake file references it at line 48 with gem release, which might handle building internally.

Recommendation: Verify that rake build still works and consider adding it explicitly if needed for local gem testing.

2. Pre-commit Hook Installation (Priority: Low)

The bin/install-hooks script is included but there's no documentation about running it.

Recommendation:

• Add installation instructions to README or CONTRIBUTING.md
• Consider auto-installing on bundle install via a post-install message
• Or add to setup documentation

3. RuboCop Target Version (Priority: Low)

.rubocop.yml sets TargetRubyVersion: 2.6, but the gemspec doesn't specify a minimum Ruby version.

Recommendation: Consider adding Ruby version requirement to gemspec:

s.required_ruby_version = '>= 2.6.0'

4. Frozen String Literal Consistency (Priority: Low)

Most files now have # frozen_string_literal: true, but specs are excluded. This is fine, but the gemspec template files in lib/generators/ might benefit from it too.

Recommendation: Consider if generator templates should also use frozen string literals for consistency.

5. CI Task Name (Priority: Very Low)

The new Rakefile has:

desc 'Run all CI checks (specs, linting, newlines)'
task ci: %i[spec lint check_newlines]

This is good, but rake build is removed from default checks. Ensure this is intentional.

🔒 Security Review

✅ No security concerns identified

• No credential handling changes
• No new external dependencies (RuboCop is dev-only)
• Pre-commit hooks don't execute arbitrary code
• Middleware changes are formatting-only

⚡ Performance Considerations

✅ Minor positive impact

• Frozen string literals reduce object allocations
• More efficient string handling with single quotes where appropriate
• No performance-critical code modified

📋 Testing & Validation Checklist

Based on the PR's test plan, verify:

• Code formatting is consistent (494 additions reviewed)
• rake -T release shows only one release task (mentioned in PR but not verified)
• rake release[1.19.0] correctly updates version (needs manual testing)
• rake build still works (unclear where build task is defined)
• CI passes with new linting workflow (check Actions tab)

💡 Recommendations

High Priority

1. Verify build task: Confirm rake build works or add explicit task
2. Document pre-commit hook: Add setup instructions

Medium Priority

3. Add Ruby version to gemspec: Match RuboCop's target version
4. Test the release workflow: Do a dry run with rake release[1.19.0,true]

Low Priority

5. Consider adding CONTRIBUTING.md: Document the new development workflow with linting requirements

🎯 Conclusion

This is a well-executed PR that solves the stated problem and significantly improves code quality. The changes are primarily cosmetic formatting improvements with one critical functional fix (removing bundler/gem_tasks).

Recommendation: ✅ Approve with minor verification

• Verify the build task functionality
• Confirm CI passes
• Consider addressing the pre-commit hook documentation

The code quality is excellent, the approach is sound, and the automated tooling will help maintain consistency going forward.

PR Review - Remove bundler/gem_tasks to fix release task conflict

Summary

This PR successfully addresses the duplicate release task conflict by removing bundler/gem_tasks and implementing a custom build task. The changes are well-structured and include significant code quality improvements through RuboCop integration.

✅ Strengths

1. Core Problem Resolution

• Correctly identifies and fixes the duplicate task conflict between bundler/gem_tasks and the custom release workflow
• The manual :build task properly replaces what bundler/gem_tasks provided
• Matches the established pattern from react_on_rails

2. Code Quality Improvements

• Adds comprehensive RuboCop configuration with appropriate rules
• Implements automated linting in CI via GitHub Actions
• Adds pre-commit hooks for developer experience (bin/install-hooks)
• Systematic code cleanup across 45 files following Ruby style conventions

3. Developer Experience

• New rake tasks: lint, lint:fix, check_newlines, fix_newlines
• Pre-commit hook installation script for consistency
• Better CI task organization (task ci: %i[spec lint check_newlines])

🔍 Areas for Consideration

1. Missing Build Task Implementation

Location: Rakefile:11

The Rakefile references a :build task in the default CI task, but I don't see the build task definition in the diff. The PR description mentions "Added manual :build task" but it's not visible in the changes shown.

Recommendation: Verify that the build task is properly implemented. Expected implementation:

desc 'Build the gem'
task :build do
  sh 'gem build cypress-on-rails.gemspec'
  FileUtils.mkdir_p 'pkg'
  FileUtils.mv Dir.glob('cypress-on-rails-*.gem'), 'pkg/'
end

2. Gemspec: Missing Frozen String Literal

Location: cypress-on-rails.gemspec:1

The gemspec file is missing the frozen string literal comment that RuboCop enforces (except in specs). While gemspec files could be excluded, they currently aren't.

Recommendation: Either add # frozen_string_literal: true at the top or exclude gemspec files from this RuboCop rule in .rubocop.yml.

3. RuboCop Configuration: Ruby Version Target

Location: .rubocop.yml:6

TargetRubyVersion: 2.6

Ruby 2.6 reached end-of-life in March 2022. Consider if this is intentional for backward compatibility or should be updated.

Recommendation: Document the minimum supported Ruby version in the README if 2.6 support is intentional, or bump to a supported version (2.7+ or preferably 3.x).

4. Pre-commit Hook Concerns

Location: bin/install-hooks:1-50

The pre-commit hook runs RuboCop on all staged files, which could be slow in large changesets.

Suggestions:

• Consider making hook installation opt-in rather than mandatory
• Add documentation about bypassing hooks with --no-verify when needed
• The hook could be optimized to only run on changed lines using rubocop --force-exclusion

5. Lint Workflow Missing Newline

Location: .github/workflows/lint.yml:26

The new lint.yml workflow file itself is missing a final newline, which would fail the check_newlines task it's supposed to run.

Impact: This is caught by the CI checks added in this PR, which is actually good validation!

6. Test Coverage for New Tasks

The new rake tasks (lint, check_newlines, etc.) don't have corresponding specs. While these are simple wrapper tasks, consider if they warrant basic smoke tests.

7. Release Task - Git Status Check

Location: rakelib/release.rake:29-31

The clean working tree check is good, but it happens after a git pull --rebase (line 40). If the rebase has conflicts or changes, the initial check becomes less meaningful.

Recommendation: Consider checking for clean working tree after the rebase as well, or document that users should be on a clean branch before running release.

🔒 Security

✅ No security concerns identified. The changes are focused on build tooling and code quality.

🧪 Test Coverage

Observations:

• Existing specs updated for RuboCop compliance (proper formatting, frozen string literals)
• No new test files added, which is appropriate for this refactoring
• The PR test plan mentions manual verification steps, which is reasonable for release tooling

Recommendation: After merging, actually test the release workflow in a dry-run mode:

rake release[1.19.0,true]

🚀 Performance

✅ No performance concerns. The linting additions run in CI and optionally in pre-commit hooks, not in production code.

📝 Documentation

Good:

• PR description is clear and includes test plan
• Release workflow examples provided
• RELEASING.md updated with newline fix

Could improve:

• Consider adding a section to README about the new linting setup
• Document how to install pre-commit hooks (bin/install-hooks)
• Mention RuboCop compliance in CONTRIBUTING.md if one exists

Final Recommendations

Before Merging:

1. ✅ Verify the :build task is properly implemented (not visible in diff)
2. ⚠️ Fix the missing newline in .github/workflows/lint.yml
3. ⚠️ Decide on frozen_string_literal in gemspec (add or exclude)
4. ⚠️ Test the release task in dry-run mode

After Merging:

1. Run bin/install-hooks and document it for contributors
2. Update CONTRIBUTING.md with linting guidelines
3. Consider documenting minimum Ruby version policy

Overall Assessment

Code Quality: ⭐⭐⭐⭐⭐ Excellent
Problem Resolution: ⭐⭐⭐⭐⭐ Fully addresses the issue
Best Practices: ⭐⭐⭐⭐☆ Very good (minor improvements suggested)
Test Coverage: ⭐⭐⭐⭐☆ Appropriate for the scope
Documentation: ⭐⭐⭐⭐☆ Good, could be enhanced

This is a solid PR that not only fixes the release task conflict but also significantly improves code quality and developer experience through automated linting. The concerns raised are minor and mostly about consistency and documentation. Great work! 🎉

PR Review: Remove bundler/gem_tasks to fix release task conflict

Summary

This PR successfully addresses the release task conflict and introduces significant code quality improvements through RuboCop integration and consistent formatting. The changes are well-structured and align with Ruby best practices.

✅ Strengths

1. Clear Problem Resolution

• Correctly identifies and fixes the duplicate release task issue
• The solution (removing bundler/gem_tasks) is appropriate and follows the react_on_rails pattern
• Clean working tree check in rakelib/release.rake:31-33 prevents releases with uncommitted changes

2. Code Quality Improvements

• Comprehensive RuboCop configuration (.rubocop.yml) with sensible defaults
• Frozen string literal pragma added consistently
• Style improvements: single quotes, proper indentation, better code readability
• All files now end with proper newlines

3. Developer Experience

• New CI workflow for linting ensures code quality on every PR
• Git pre-commit hook script (bin/install-hooks) automates quality checks
• Clear rake task naming: task ci consolidates all CI checks

4. Refactoring Quality

• Simplified conditionals throughout
• Better error handling with StandardError instead of bare rescue
• Improved code organization with guard clauses

⚠️ Issues and Concerns

1. Critical: Dry Run Mutates Repository (rakelib/release.rake:43)

The gem bump command modifies lib/cypress_on_rails/version.rb even during dry runs, defeating the purpose of --dry-run.

Suggested fix: Guard the bump command with unless is_dry_run

2. Missing Build Task (Rakefile)

The PR description mentions adding a manual :build task to replace what bundler/gem_tasks provided, but this task is missing from the new Rakefile. The old task default: spec build now references task default: ci, but there is no build step.

Action needed: Verify if a build task should be added or if this was intentional

3. Test Coverage Gaps

With 45 files changed (494 additions, 288 deletions), there is no evidence of:

• Tests for the new lint tasks
• Tests verifying the release task works correctly with the new structure
• Tests for pre-commit hook functionality

4. Potential Breaking Changes

• Removed test_files from gemspec - verify this does not break gem packaging
• Changed default rake task from spec build to ci - could break existing workflows

🔍 Code Quality Notes

Good Practices Observed:

• lib/cypress_on_rails/middleware.rb:34-40: Improved ternary logic for cleaner code
• lib/cypress_on_rails/server.rb:62-65: Guard clause pattern improves readability
• lib/cypress_on_rails/configuration.rb: Method alias syntax modernization

Minor Suggestions:

• Consider adding comment in Rakefile explaining why bundler/gem_tasks was removed
• Document bin/install-hooks installation in README
• .rubocop.yml line 76 missing final newline (ironic given the lint rules!)

🎯 Performance Considerations

No performance concerns identified. The middleware changes are style-only and do not affect runtime performance.

🔒 Security

• ✅ Good: Added rubygems_mfa_required to gemspec
• ✅ Good: Clean working tree check prevents accidental releases
• ⚠️ Consider: Document that bin/install-hooks must be run manually

Recommendations

1. High Priority: Fix the dry run mutation issue
2. High Priority: Clarify whether build task should exist
3. Medium Priority: Add tests for new rake tasks
4. Low Priority: Update README with pre-commit hook setup instructions

Conclusion

This is a solid PR that improves code quality and resolves the release task conflict. The RuboCop integration and style improvements are valuable additions. However, the dry run bug should be fixed before merging, and the missing build task should be clarified.

Recommendation: Request changes for the dry run issue, then approve after fix.

Review conducted following repository best practices and Ruby community standards.

4. Gemspec Improvements

• Added rubygems_mfa_required: 'true' - excellent security practice
• Proper dependency organization
• Modern Ruby code style

⚠️ Potential Issues & Concerns

1. Missing Build Task Implementation (CRITICAL)

The Rakefile removes bundler/gem_tasks but I don't see a :build task defined anywhere:

# Rakefile references :build but doesn't define it
task ci: %i[spec lint check_newlines]

The PR description mentions "Added manual :build task" but I cannot find it in the changed files. The default task was task default: %w[spec build] and is now task default: :ci, which doesn't include a build step.

Recommendation: Verify that a :build task exists or add one:

desc 'Build the gem'
task :build do
  require 'bundler/gem_helper'
  Bundler::GemHelper.install_tasks
  Rake::Task['build'].invoke
end

Or use bundler's gem tasks selectively:

require 'bundler/gem_helper'
Bundler::GemHelper.install_tasks(name: 'cypress-on-rails')
Rake::Task[:release].clear  # Remove bundler's release task

2. Pre-commit Hook Unquoted Variables (MEDIUM)

In bin/install-hooks:26, the shell variable should be quoted:

# Current (line 26)
bundle exec rubocop $files

# Should be
bundle exec rubocop "$files"

This prevents word splitting issues with filenames containing spaces.

3. Newline Check Performance (LOW)

The check_newlines and fix_newlines tasks in rakelib/lint.rake read entire file contents into memory. For large files, this could be inefficient:

# Current approach (lines 28-29, 50-51)
content = File.read(file)
unless content.empty? || content.end_with?("\n")

Suggestion: Consider using file seeking for large files:

next if File.zero?(file)
File.open(file, 'rb') do |f|
  f.seek(-1, IO::SEEK_END)
  files_without_newline << file if f.read(1) != "\n"
end

4. Server.rb Error Handling (LOW)

In lib/cypress_on_rails/server.rb:86-87, the rollback check could be more defensive:

# Current
if @transactional && defined?(ActiveRecord::Base) && ActiveRecord::Base.connection.transaction_open?
  ActiveRecord::Base.connection.rollback_transaction
end

Consider wrapping in a rescue to handle connection errors gracefully.

5. RuboCop Configuration Concern (LOW)

.rubocop.yml:6 sets TargetRubyVersion: 2.6, but Ruby 2.6 reached EOL in March 2022. Consider updating to at least Ruby 2.7 or 3.0+ for security and performance.

🔒 Security Review

✅ Positive Security Aspects:

1. MFA Required: rubygems_mfa_required: 'true' in gemspec - excellent addition
2. No Credential Exposure: No hardcoded secrets or sensitive data
3. Safe Shell Commands: Proper use of spawn with array syntax (not string interpolation)
4. Input Validation: Release task validates git status before proceeding

⚠️ Minor Concerns:

1. The eval usage in lib/cypress_on_rails/command_executor.rb:8 is inherent to the design (evaluating test commands), but ensure this is only enabled in test environments
2. Pre-commit hook uses bundle exec which is good for avoiding gem confusion

📋 Test Coverage

The PR updates test files with RuboCop fixes but doesn't add new tests for:

• The modified Rakefile tasks (:ci, :default)
• The new lint tasks (check_newlines, fix_newlines)

📊 Overall Assessment

Score: 8/10

This is a solid PR that solves the release task conflict and significantly improves code quality. The RuboCop integration and linting infrastructure are valuable additions. However, the critical question about the missing :build task needs clarification before merging.

The code quality improvements are extensive and well-executed - 45 files touched with consistent style improvements. The security posture is enhanced with MFA requirements. Once the build task concern is addressed, this will be ready to merge.

Recommendation: Request clarification on the build task, then approve with the minor fixes suggested above.
