🚨 BREAKING: Fixed installation sequence that was causing errors **Root Cause Found:** - React on Rails generator requires package.json to exist - Rails 8 with --skip-javascript doesn't create package.json - Previous instructions tried React on Rails first → package.json error **Fix Applied:** 1. ✅ Always install Shakapacker FIRST (creates package.json) 2. ✅ Then install React on Rails (can add JS dependencies) **Updated All 3 Scenarios:** - New Rails App: Shakapacker → React on Rails - Existing Rails App: Shakapacker → React on Rails - Vite Migration: Remove Vite → Shakapacker → React on Rails **Validated:** - Created test app following new instructions → SUCCESS - React component renders, HMR works, no errors - Updated to current gem versions (15.0, 8.3) This fix prevents the "package.json not found" error that breaks setup.

- Added git restore permission for repository management - Added node command permission for test automation with Puppeteer - Test app successfully created at ../react_on_rails-test-apps/test-react-on-rails-v15-hello-world-on-rails-v8 - Demonstrates React on Rails v15.0 with Rails 8.0.2.1 using corrected Shakapacker-first installation sequence 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

The docs/quick-start-readme.md file documented the spec/quick-start example app which was removed in the previous commit.

🔍 Code Review for PR #1811: Fix markdown heading formatting consistency

Thank you for this PR! I have conducted a thorough review of the changes. Here is my comprehensive feedback:

📊 Overall Assessment

This PR claims to fix markdown heading formatting consistency but actually introduces significant scope creep with major additions that go well beyond the stated purpose.

⚠️ Critical Issues

1. Scope Creep - Major Concern 🚨

The PR description states it is for "fixing markdown heading formatting consistency" but actually:

Adds 4 entirely new documentation files totaling 800+ lines
Substantially rewrites existing documentation structure
Changes from simple formatting fixes to a complete documentation overhaul

Files that should not be in this PR:

AI_AGENT_INSTRUCTIONS.md (231 lines)
DOCS_PR_SUMMARY.md (148 lines)
DOCUMENTATION_COMPREHENSIVE_IMPROVEMENT_PLAN.md (288 lines)
DOCUMENTATION_IMPROVEMENT_PLAN.md (167 lines)
docs/README.md (117 lines - new file)
docs/quick-start/README.md (175 lines - new file)
docs/troubleshooting/README.md (317 lines - new file)

2. CLAUDE.md Compliance Issues ⚠️

Per the repository CLAUDE.md requirements:

❌ No evidence that bundle exec rubocop was run on changed files
❌ No verification that all files end with newline characters
❌ No indication that rake autofix or Prettier was used for formatting

3. Documentation Quality Concerns 📝

While some improvements are good, there are issues:

Inconsistent emoji usage - Overuse in new files vs minimal in existing docs
Broken links risk - Major restructuring without verifying all internal links
Version confusion - New docs mention "react_on_rails ~> 15.0" while other places show "16.0.0"

✅ Good Changes (that align with PR title)

The actual heading formatting fixes are appropriate:

✅ Changing "## Title: Subtitle" to "## Title - Subtitle"
✅ Fixing "## assets:precompile" to "## Assets Precompile"
✅ Standardizing option headings

🔧 Recommendations

Immediate Actions Required:

Split this PR into two separate PRs:
- PR 1: Markdown heading formatting fixes only (as described)
- PR 2: Documentation overhaul (new files, restructuring)

Run required checks:

bundle exec rubocop
rake autofix
yarn start format.listDifferent

Verify trailing newlines on all modified files
Test all documentation links to ensure nothing is broken

For the Documentation Overhaul (separate PR):

Justify the changes - Why is a complete overhaul needed?
Get maintainer buy-in - Such large changes need discussion
Ensure consistency - Match existing documentation style
Update all cross-references - Many files reference the old structure

🐛 Potential Bugs

Version mismatch: getting-started.md shows --version=16.0.0 while new AI instructions show ~> 15.0
Missing file references: New docs reference files that may not exist (/guides/installation.md, /api/README.md)

🔒 Security Considerations

✅ No security issues identified in the changes

🚀 Performance Impact

✅ Documentation-only changes, no runtime performance impact

📈 Test Coverage

⚠️ No tests for documentation structure or link validity

💡 Suggestions for Improvement

Keep PRs focused - One clear purpose per PR
Discuss major changes first - Open an issue for documentation overhaul
Progressive enhancement - Start with small improvements, iterate
Maintain consistency - Do not introduce new patterns (heavy emoji use) without discussion

📋 Checklist for Author

Before this PR can be merged:

Remove all new documentation files unrelated to heading formatting
Run bundle exec rubocop and fix violations
Run rake autofix for formatting
Ensure all files end with newline
Update PR description to match actual changes
Or: Close this PR and create two separate, focused PRs

Summary

While the documentation improvements have merit, this PR needs to be split. The formatting fixes are good and ready to merge once separated. The documentation overhaul should be its own PR with proper discussion and review.

Happy to review the split PRs once created! 🚀
