🏗️ Implement cross-tool architecture (v2)

[TechNickAI]

Summary

Major architectural change to support multiple AI coding tools (Claude Code, Cursor, Windsurf, Aider, and others).

Key Changes

• Rules location: Moved from .cursor/rules/ to rules/ at project root

  • .cursor/rules/ now symlinks to ../rules/ for Cursor compatibility
  • Tool-agnostic location works with any AI coding tool

• AGENTS.md standard adoption:

  • Created AGENTS.md as canonical project context file
  • CLAUDE.md symlinks to AGENTS.md for Claude Code compatibility
  • AGENTS.md is an emerging cross-tool standard (20,000+ GitHub repos, backed by OpenAI, Google, Cursor, Aider)

• Command renaming: /load-cursor-rules → /load-rules (tool-agnostic naming)

• Migration support: Added architecture detection to /ai-coding-config update

  • Detects v1 (Cursor-first) vs v2 (cross-tool) architecture
  • Offers guided migration with backup and rollback
  • Handles fresh installs, existing Cursor rules, and previous ai-coding-config installations

Future Extensibility

Adding support for new tools is simple:

.windsurf/
└── rules/ → ../rules/    # Same symlink pattern

When Claude Code officially supports AGENTS.md (open feature request #6235), the CLAUDE.md symlink becomes unnecessary.

Test plan

• Verify rules/ directory contains all rules
• Verify .cursor/rules/ symlink resolves correctly
• Verify /load-rules command works
• Test /ai-coding-config update on a v1 project to verify migration detection
• Test fresh install creates v2 structure

Pull Request Review - Cross-Tool Architecture (v2)

Overview

This PR implements a significant architectural improvement to support multiple AI coding tools (Claude Code, Cursor, Windsurf, Aider) by moving from a Cursor-first structure to a tool-agnostic approach. The changes are well-designed and thoroughly documented.

---

✅ Strengths

1. Clear Architecture Vision

• Moving rules/ to project root as canonical source with .cursor/rules/ symlink is the right approach
• Adoption of AGENTS.md standard shows forward thinking (20k+ repos, backed by major players)
• Extensibility pattern is simple and clear for adding new tools

2. Excellent Migration Support

The /ai-coding-config update command (lines 189-227 in ai-coding-config.md) handles migration thoughtfully:

• Detects v1 vs v2 architecture correctly
• Offers user choices (migrate/skip/show changes)
• Creates backups before migration (cp -r .cursor/rules rules-backup)
• Provides clear rollback path

3. Comprehensive Existing Config Detection

Lines 33-81 in ai-coding-config.md cover 4 distinct scenarios:

• Fresh projects
• Existing Cursor rules (preserves user customizations)
• Previous v1 installations
• Already on v2

This prevents data loss and respects user work.

4. Consistent Path Updates

All 70+ files correctly update references from .cursor/rules/ to rules/:

• AGENTS.md files
• Commands (load-rules, generate-*, etc.)
• Documentation
• Context files

---

🔍 Issues & Recommendations

CRITICAL: Missing Bootstrap Script Update

The bootstrap script (scripts/bootstrap.sh) was not updated to create the v2 architecture for fresh installations. It only copies the ai-coding-config command.

Problem: Fresh installations won't get the new structure automatically.

Required Changes to scripts/bootstrap.sh:

# After line 52, add:
echo "📁 Setting up cross-tool architecture..."

# Create rules directory if it doesn't exist
if [ \! -d "rules" ]; then
    mkdir -p rules
    echo "✓ Created rules/ directory"
fi

# Create .cursor directory structure if needed
mkdir -p .cursor

# Create symlink from .cursor/rules to ../rules if not exists
if [ \! -e ".cursor/rules" ]; then
    ln -s ../rules .cursor/rules
    echo "✓ Created .cursor/rules symlink"
elif [ \! -L ".cursor/rules" ]; then
    echo "⚠️  Warning: .cursor/rules exists but is not a symlink"
    echo "   Run /ai-coding-config update to migrate"
fi

# Create AGENTS.md symlink structure
if [ \! -e "CLAUDE.md" ] && [ -f "AGENTS.md" ]; then
    ln -s AGENTS.md CLAUDE.md
    echo "✓ Created CLAUDE.md symlink"
fi

echo ""

MEDIUM: Symlink Verification Missing

The migration process should verify symlinks were created successfully.

Recommendation: Add verification after symlink creation:

# After: ln -s ../rules .cursor/rules
if [ \! -L .cursor/rules ]; then
    echo "❌ Failed to create .cursor/rules symlink"
    exit 1
fi

MEDIUM: .gitignore Consideration

The PR doesn't mention updating .gitignore patterns.

Check needed:

• Should symlinks be ignored? (Generally no, they should be committed)
• Are there any tool-specific ignore patterns needed?

LOW: Command Symlink Rename

.cursor/commands/load-cursor-rules.md deleted, .cursor/commands/load-rules.md created as symlink.

Observation: This is good for tool-agnostic naming, but users with existing references to load-cursor-rules will experience a breaking change.

Suggestion: Consider deprecation path:

• Keep old symlink with deprecation notice
• Add auto-redirect or warning in first execution

LOW: Documentation - Rollback Instructions

Migration includes backup (rules-backup) but no explicit rollback instructions.

Recommendation: Document rollback process:

# If migration fails or you want to revert:
rm -rf rules
rm .cursor/rules
mv rules-backup .cursor/rules

---

🧪 Testing Recommendations

Based on PR test plan, ensure these scenarios work:

1. Fresh Install Test:

   # New project, run bootstrap
   curl -fsSL https://raw.githubusercontent.com/TechNickAI/ai-coding-config/main/scripts/bootstrap.sh | bash
   # Verify: rules/ exists, .cursor/rules -> ../rules symlink created
   test -d rules && test -L .cursor/rules && echo "✓ Pass" || echo "✗ Fail"

2. V1 Migration Test:

   # Project with .cursor/rules/ as real directory
   /ai-coding-config update
   # Verify: rules/ now canonical, .cursor/rules is symlink, backup exists
   test -d rules && test -L .cursor/rules && test -d rules-backup && echo "✓ Pass"

3. Symlink Following Test:

   # Verify Cursor can read through symlink
   ls -la .cursor/rules/
   cat .cursor/rules/git-interaction.mdc

4. Command Rename Test:

   # Verify /load-rules works in both Claude Code and Cursor
   /load-rules  # Should load successfully

5. Cross-Platform Test:

   • Test symlinks on macOS, Linux, and Windows (WSL)
   • Windows symlinks require different handling

[TechNickAI]

Addressed Claude Code Review feedback:

✅ Updated bootstrap.sh to create v2 architecture for fresh installs:

• Creates rules/ directory
• Creates .cursor/rules symlink pointing to ../rules
• Added symlink verification with error handling
• Detects existing v1 installs and suggests migration

Declined with rationale:

• Deprecation path for load-cursor-rules: Over-engineering for actively maintained project. Users update directly.
• Rollback documentation: Backup exists (rules-backup), straightforward to restore if needed.
• .gitignore verification: Symlinks should be committed - no changes needed.

Code Review: PR #7 - Cross-Tool Architecture (v2)

Overall Assessment

Status: Approved with Minor Suggestions ✅

This is a well-executed architectural refactoring that significantly improves the project's cross-tool compatibility. The migration from Cursor-first to tool-agnostic structure is thoughtfully designed with proper backwards compatibility and migration paths.

Strengths

Architecture & Design ⭐

1. Clean Separation of Concerns: Moving rules/ to project root as canonical source with symlinks for tool compatibility is elegant and maintainable

2. AGENTS.md Standard Adoption: Aligning with the emerging cross-tool standard (20,000+ repos) shows good ecosystem awareness

3. Migration Strategy: The detection and guided migration logic in ai-coding-config.md:189-227 is comprehensive:

   • Detects v1 vs v2 architecture accurately
   • Offers user choice before making changes
   • Includes backup creation (cp -r .cursor/rules rules-backup)
   • Provides clear rollback path

4. Backwards Compatibility: Supporting both fresh installs and existing installations gracefully

Code Quality ✅

1. Consistent Naming: /load-cursor-rules → /load-rules is more tool-agnostic and future-proof

2. Documentation Updates: All 72 files updated consistently for path references (.cursor/rules/ → rules/)

3. Bootstrap Script Enhancement (scripts/bootstrap.sh:55-77):

   • Detects existing architecture before proceeding
   • Creates v2 structure for fresh installs
   • Warns users to run update for migrations
   • Good error handling with symlink verification

Issues & Recommendations

Critical Issues 🔴

None identified - No blocking issues

Important Suggestions 🟡

1. Symlink Verification in Migration (ai-coding-config.md:216-224)

   Issue: After creating symlinks during migration, there's no verification they were created successfully

   Current code (line 219-221):

   b. Move rules: `mv .cursor/rules rules`
   c. Create symlink: `ln -s ../rules .cursor/rules`
   d. Create AGENTS.md (copy from CLAUDE.md if exists, or create new)

   Suggestion: Add verification step:

   b. Move rules: `mv .cursor/rules rules`
   c. Create symlink: `ln -s ../rules .cursor/rules`
   c2. Verify symlink: `test -L .cursor/rules || (echo "Failed to create symlink" && exit 1)`
   d. Create AGENTS.md (copy from CLAUDE.md if exists, or create new)

   This matches the pattern used in bootstrap.sh:66-69 which already does this verification.

2. Path Update Validation (ai-coding-config.md:222)

   Issue: Step "f. Update @ references in AGENTS.md from .cursor/rules/ to rules/" is critical but has no validation

   Suggestion: Add verification:

   f. Update @ references in AGENTS.md from `.cursor/rules/` to `rules/`
   f2. Verify no old paths remain: `grep -q '\.cursor/rules' AGENTS.md && echo "Warning: old paths still present"`

3. Rollback Documentation (ai-coding-config.md:189-227)

   Issue: Migration creates backup (rules-backup) but doesn't document rollback procedure

   Suggestion: Add rollback instructions in the migration section:

   If migration fails or issues occur:
   - Restore from backup: `rm -rf rules && mv rules-backup .cursor/rules`
   - Remove symlinks: `rm -f .cursor/rules CLAUDE.md`
   - Restore AGENTS.md backup if needed

Minor Improvements 🟢

4. Race Condition in Detection (ai-coding-config.md:204)

   Current: test -L .cursor/rules && test -L CLAUDE.md && test -f AGENTS.md

   Issue: Doesn't handle edge case where migration is partially complete (e.g., rules moved but CLAUDE.md not yet symlinked)

   Suggestion: Make detection more robust:

   # V2 requires ALL of: rules/ dir, .cursor/rules symlink, AGENTS.md file, CLAUDE.md symlink
   test -d rules && test -L .cursor/rules && test -f AGENTS.md && test -L CLAUDE.md

5. Bootstrap Script User Guidance (scripts/bootstrap.sh:73-74)

   Current: Only tells user to run /ai-coding-config update

   Enhancement: Could be more specific:

   echo "⚠️  Detected existing .cursor/rules/ directory (v1 architecture)"
   echo "   Your project uses the legacy structure. To migrate to v2:"
   echo "   1. From Claude Code: /ai-coding-config update"
   echo "   2. From Cursor: @ai-coding-config update this project"
   echo "   This will guide you through migration with backup and rollback options."

6. Documentation Clarity (.claude/commands/ai-coding-config.md:155)

   Current: .cursor/CLAUDE.md and .claude/CLAUDE.md

   Issue: In v2 architecture, CLAUDE.md at root should symlink to AGENTS.md, not in subdirectories. This line seems to refer to the directory-level CLAUDE.md files which document directory purpose (different from root AGENTS.md/CLAUDE.md)

   Suggestion: Clarify naming to avoid confusion:

   • Root level: AGENTS.md (canonical), CLAUDE.md (symlink to AGENTS.md)
   • Directory level: Maybe rename to DIRECTORY.md or README.md to distinguish from root CLAUDE.md

Security Assessment ✅

• No security concerns identified
• Migration script properly uses relative symlinks (not absolute paths)
• No credentials or sensitive data handling
• Backup creation prevents data loss

Test Coverage 📋

PR includes test plan with 5 verification points:

• ✅ Structural tests (directory, symlink verification)
• ✅ Functional tests (command execution, migration)
• ⚠️ Suggestion: Add test for partial migration failure scenario

Recommended Additional Tests:

1. Test migration when .cursor/rules contains uncommitted changes
2. Test behavior when symlink creation fails (permission issues)
3. Test rollback procedure from backup

Performance Considerations

• ✅ No performance concerns
• Moving files vs copying reduces disk usage
• Symlinks have negligible overhead

Documentation Quality ⭐

• Excellent PR description with architecture diagram
• Clear migration path explanation
• Good use of frontmatter in .mdc files
• Inline documentation in commands is thorough

Breaking Changes

• ✅ Well-managed: No breaking changes for end users
• Migration is opt-in via /ai-coding-config update
• Old structure continues to work until user chooses to migrate

Recommendations Summary

Must Address Before Merge

• None - PR is ready to merge as-is

Should Consider

1. Add symlink verification after migration (matches bootstrap.sh pattern)
2. Add path update validation
3. Document rollback procedure

Nice to Have

4. More robust architecture detection
5. Enhanced bootstrap user guidance
6. Clarify directory-level vs root-level CLAUDE.md naming

Final Verdict

Approved ✅

This is excellent work. The architectural change is well-thought-out, the implementation is solid, and the migration strategy is user-friendly. The suggestions above are minor improvements that would make an already-good PR even better, but they're not blockers.

The consistency across 72 files with no apparent errors is impressive. The migration logic handles edge cases well, and the user experience is thoughtfully designed.

Recommendation: Merge after considering the symlink verification suggestion (#1), as it's a pattern you're already using in bootstrap.sh and would make the migration more robust.

---

Great work on this architectural improvement! The cross-tool compatibility will significantly improve the project's usefulness across different AI coding environments.

PR Review: Cross-Tool Architecture (v2)

Summary

This is a well-thought-out architectural refactoring that successfully migrates the project from a Cursor-first design to a cross-tool compatible structure. The changes are comprehensive, properly documented, and include migration support for existing users.

✅ Strengths

1. Excellent Architecture Design

• Moving rules/ to the project root with .cursor/rules/ as a symlink is the right approach for multi-tool compatibility
• Adopting the AGENTS.md standard aligns with emerging cross-tool conventions
• The symlink-based approach maintains backward compatibility while enabling forward progress

2. Migration Support

The /ai-coding-config update command includes sophisticated migration detection:

• Handles 4 distinct scenarios (fresh install, existing Cursor rules, v1 installs, v2 already installed)
• Offers user choice with clear explanations
• Includes backup mechanism before migration
• Provides rollback options

3. Comprehensive Path Updates

All 43 files with path references have been systematically updated from .cursor/rules/ to rules/ - this was executed thoroughly.

4. Bootstrap Script Enhancement

The bootstrap script now:

• Detects existing architecture versions
• Creates v2 structure for fresh installs
• Guides users to migration path for v1 installs
• Includes proper error handling for symlink creation

🔍 Code Quality Observations

Security Considerations

✅ Good: The bootstrap script includes proper validation:

• Git repository detection
• OS compatibility checks
• Symlink verification

⚠️ Minor: Consider adding validation that symlinks point to expected targets (defense against symlink attacks, though low risk in this context)

Error Handling

The bootstrap script handles key failure modes well:

if [ ! -L ".cursor/rules" ]; then
    echo "❌ Failed to create .cursor/rules symlink"
    exit 1
fi

However, the migration logic in ai-coding-config.md could benefit from additional error handling:

• What if mv .cursor/rules rules fails due to permission issues?
• What if rules/ already exists during migration?
• Consider adding validation after each migration step

Testing

⚠️ Gap: No automated tests for the migration logic. Consider adding:

• Shell script tests for bootstrap.sh using bats or similar
• Integration tests for the migration scenarios
• Test coverage for symlink creation and validation

Documentation

✅ Excellent: The PR description is thorough with:

• Clear architecture diagrams
• Migration path explanation
• Future extensibility examples
• Proper references to standards (AGENTS.md, feature request #6235)

🐛 Potential Issues

1. Symlink Handling on Windows

While the PR mentions "macOS and Linux" support in bootstrap.sh, Windows users (particularly in Git Bash or WSL) might encounter issues with symlinks. Consider:

• Adding Windows detection and guidance
• Documenting symlink limitations on Windows
• Potentially using directory junctions as fallback on Windows

2. Migration Race Conditions

If a user has .cursor/rules/ open in their IDE during migration, the mv command might fail or cause unexpected behavior. Consider:

• Adding a check for open file handles
• Warning users to close IDEs before migration
• More robust error messages if migration fails mid-process

3. Incomplete Migration Rollback

The migration creates rules-backup but doesn't provide an automated rollback command. If migration fails at step (f) or (g), the user is left in an inconsistent state. Suggestion:

# Add to migration logic
if [[ $? -ne 0 ]]; then
    echo "Migration failed, rolling back..."
    rm -rf rules
    mv rules-backup .cursor/rules
    exit 1
fi

4. Path Reference in Detection Logic

In ai-coding-config.md line 204:

Detection: `test -L .cursor/rules && test -L CLAUDE.md && test -f AGENTS.md`

This detection could fail if run from a subdirectory. Consider making paths absolute or adding a check for working directory.

🎯 Performance Considerations

✅ No performance concerns - symlinks are filesystem-native and have negligible overhead
✅ The migration is a one-time operation, so performance is not critical

📊 Best Practices

Following Project Standards

✅ Excellent adherence to project's own rules:

• Follows prompt-engineering.mdc guidelines (goal-focused, minimal anti-patterns)
• Respects git-interaction.mdc (proper commit messages with Co-Authored-By)
• Clear, descriptive commit messages with emojis

Code Organization

✅ Changes are logically grouped
✅ Symlink changes are properly tracked in git
✅ Directory structure follows the documented architecture

🔐 Security Review

✅ Low Risk: No sensitive operations
✅ Symlinks are relative (../rules), not absolute - reduces path traversal risks
✅ No credential handling or network operations beyond git clone
⚠️ Minor: The curl-to-bash bootstrap pattern is convenient but inherently risky - consider documenting that users should inspect the script first

📋 Recommendations

High Priority

1. Add error handling for partial migration failures - automated rollback on error
2. Test migration on a v1 project - verify the detection and migration actually works end-to-end
3. Document Windows behavior - clarify symlink limitations and alternatives

Medium Priority

4. Add shell script tests - at least basic tests for bootstrap.sh
5. Improve symlink validation - verify targets exist and point to expected locations
6. Add migration dry-run option - let users preview changes before committing

Low Priority

7. Consider adding a health check command - validates architecture consistency
8. Document manual rollback procedure - if automated migration fails

✨ Standout Features

1. Forward-thinking design - extensibility for future tools (Windsurf, etc.) is built in
2. User-centric migration - offers choice, explanation, and guidance
3. Comprehensive scope - touches all 43 affected files consistently
4. Well-documented - both in PR description and inline comments

🎬 Final Verdict

Recommended for merge with consideration for the error handling improvements.

This is a solid architectural improvement that positions the project well for multi-tool support. The migration logic is thoughtful, though it could benefit from more robust error handling and testing. The v2 architecture is a clear improvement over v1, and the migration path respects existing users while enabling new capabilities.

Suggested Pre-Merge Actions:

1. ✅ Test the migration manually on a v1 project (appears to be in test plan)
2. ⚠️ Add error handling for partial migration failures
3. ⚠️ Consider adding basic shell script tests

Test Plan Verification

The PR's test plan covers the key scenarios:

• ✅ Verify rules/ directory structure
• ✅ Verify symlink resolution
• ✅ Test /load-rules command
• ✅ Test migration detection
• ✅ Test fresh install

Overall Quality: 8.5/10 - Excellent design and execution, with room for improved error handling and test coverage.

Great work on this refactoring! The cross-tool architecture is a significant improvement. 🚀

[claude]

Pull Request Review - Cross-Tool Architecture (v2)

Overview

This is a significant architectural improvement that migrates from a Cursor-first structure to a cross-tool compatible architecture. The changes are well-motivated and enable support for multiple AI coding tools (Claude Code, Cursor, Windsurf, Aider).

---

✅ Strengths

1. Excellent Architecture Design

• Moving rules/ to project root with .cursor/rules/ as a symlink is the right approach
• AGENTS.md standard adoption is forward-thinking (20k+ repos already using it)
• Maintains backward compatibility through symlinks
• Single source of truth principle is maintained

2. Comprehensive Migration Support

The /ai-coding-config update command handles 4 distinct scenarios elegantly:

• Fresh projects
• Existing Cursor rules (no ai-coding-config)
• v1 installations
• v2 installations

The detection logic in ai-coding-config.md:65-75 is thorough and considers all edge cases.

3. Robust Bootstrap Script

scripts/bootstrap.sh handles multiple installation states correctly:

• Fresh installs → creates v2 structure (lines 62-70)
• Existing v1 → suggests migration (lines 71-74)
• Existing v2 → confirms status (lines 75-76)
• Missing case handled (lines 77-84): rules/ exists but .cursor/rules doesn't

4. Consistent Documentation Updates

All 70+ file references from .cursor/rules/ to rules/ were updated systematically, including:

• Commands, agents, documentation
• Symlink updates (.cursor/commands/load-rules.md)
• AGENTS.md references

---

⚠️ Issues & Concerns

1. Critical: Migration Data Loss Risk 🔴

In .claude/commands/ai-coding-config.md:216-224, the migration steps have a serious bug:

a. Create backup: `cp -r .cursor/rules rules-backup`
b. Move rules: `mv .cursor/rules rules`
c. Create symlink: `ln -s ../rules .cursor/rules`

Problem: If rules/ already exists as a symlink to .cursor/rules/ (v1 architecture), step (b) will fail or overwrite.

Scenario:

• User has v1 setup where rules/ → .cursor/rules/ (symlink)
• Migration runs mv .cursor/rules rules
• This could fail because rules already exists

Fix needed:

# Before migration, check and remove the old symlink
if [ -L "rules" ]; then
    rm rules
fi
cp -r .cursor/rules rules-backup
mv .cursor/rules rules
ln -s ../rules .cursor/rules

Reference: ai-coding-config.md:216-224

2. Security: Command Injection in Bootstrap 🟡

bootstrap.sh:38-40:

cd ~/.ai_coding_config
git pull
cd - > /dev/null

Issue: If ~/.ai_coding_config is compromised or user has malicious hooks, git pull could execute arbitrary code.

Recommendation: Add verification

if [ -d "$HOME/.ai_coding_config/.git" ]; then
    cd ~/.ai_coding_config
    # Verify remote URL before pulling
    REMOTE=$(git config --get remote.origin.url)
    if [[ "$REMOTE" == *"TechNickAI/ai-coding-config"* ]]; then
        git pull
    else
        echo "⚠️  Warning: Unexpected remote URL: $REMOTE"
        echo "   Skipping update for security"
    fi
    cd - > /dev/null
fi

3. Incomplete Rollback on Migration Failure 🟡

Migration steps (.claude/commands/ai-coding-config.md:216-224) don't handle failures gracefully:

• If step (c) fails (symlink creation), .cursor/rules is gone but not recreated
• If step (f) fails (@ reference updates), some references will be broken
• No rollback mechanism from rules-backup

Recommendation: Add error handling

3. If migration accepted:
   a. Create backup: `cp -r .cursor/rules rules-backup`
   b. Move rules: `mv .cursor/rules rules`
   c. Create symlink: `ln -s ../rules .cursor/rules`
      - If this fails, restore: `mv rules .cursor/rules && rm -rf rules-backup`
   d-h. [subsequent steps with similar error handling]
   i. Remove backup only after verification: `rm -rf rules-backup`

4. Documentation Inconsistency 🟡

In AGENTS.md:23 vs the actual structure:

• States: "rules/ - Canonical coding standards (.mdc files, .cursor/rules/ symlinks here)"
• This is slightly confusing - .cursor/rules/ doesn't symlink individual files, it symlinks the entire directory

Clearer wording:

- `rules/` - Canonical coding standards (`.mdc` files)
- `.cursor/rules/` - Symlink to `../rules/` for Cursor compatibility

5. Minor: Symlink Verification Edge Case 🟢

bootstrap.sh:66-69:

if [ ! -L ".cursor/rules" ]; then
    echo "❌ Failed to create .cursor/rules symlink"
    exit 1
fi

This checks if the symlink was created, but doesn't verify it points to the correct target (../rules).

Enhancement:

if [ ! -L ".cursor/rules" ] || [ "$(readlink .cursor/rules)" != "../rules" ]; then
    echo "❌ Failed to create .cursor/rules symlink correctly"
    exit 1
fi

---

🔍 Testing Recommendations

Before merging, test these scenarios:

1. Fresh install (clean directory)

   • ✓ Should create v2 structure

2. Existing v1 installation

   • ⚠️ Test migration with rules/ → .cursor/rules/ symlink

1. Migration data loss risk - Add symlink cleanup before mv command
2. Add rollback mechanism - Migration should be atomic or recoverable

Should Fix:

3. Bootstrap security - Verify git remote before pulling
4. Error handling - Add failure recovery at each migration step

Nice to Have:

5. Documentation clarity - Clarify symlink description in AGENTS.md
6. Symlink verification - Check symlink target in bootstrap

✨ Conclusion

This is a well-designed architectural improvement that positions the project for multi-tool support. The code quality is high, documentation is thorough, and the migration approach is thoughtful.

However, the migration logic has a critical data loss risk that must be addressed before merging. Once the migration safety is improved, this will be an excellent enhancement.

Recommendation: Request changes to fix the migration safety issues, then approve.

Great work on this major architectural shift! The AGENTS.md standard adoption is particularly forward-thinking. 🚀

Addressed Cursor bot feedback on rules/README.md in d5d1870:

Issue: Patterns 2 and 3 showed mkdir -p .cursor/rules but then operated on rules/ paths

Fix: Updated to show correct v2 architecture:

• Create rules/ as the canonical directory
• Create .cursor/rules symlink for Cursor compatibility

All documentation patterns now align with the v2 cross-tool architecture.

Pull Request Review: Cross-Tool Architecture (v2)

Overview

This is a well-designed architectural migration that moves the project from a Cursor-first approach to a tool-agnostic structure supporting multiple AI coding tools. The implementation is solid with good migration support and documentation.

✅ Strengths

1. Excellent Architecture Design

• Moving rules/ to project root as canonical source is the right call
• Symlink pattern (.cursor/rules/ → ../rules/) maintains backward compatibility
• AGENTS.md adoption aligns with emerging cross-tool standards (20K+ repos)
• Extensibility for future tools (Windsurf, Aider, etc.) is straightforward

2. Comprehensive Migration Support

The /ai-coding-config update architecture detection (lines 189-227 in ai-coding-config.md) is impressive:

• Detects v1 vs v2 architecture automatically
• Offers guided migration with clear explanations
• Handles 4 distinct scenarios (fresh, existing Cursor rules, v1 installation, v2)
• Includes backup and rollback capability
• Preserves user customizations

3. Consistent Refactoring

• Renamed /load-cursor-rules → /load-rules throughout (70+ files)
• Updated all @ references from .cursor/rules/ to rules/
• Symlinks properly created for cross-tool compatibility
• Command symlinks maintained correctly

4. Good Documentation

• Clear PR description with architecture diagram
• Updated AGENTS.md to reflect new structure
• Migration instructions are thorough

⚠️ Issues to Address

1. Incomplete Reference Updates (Minor)

Some documentation files still reference .cursor/rules/:

docs/project-context-research.md:26,463

• Still mentions .cursor/rules/ as the modern approach
• Should be updated to reflect rules/ as canonical

implementation-plan.md:35,42,241,855

• Multiple references to .cursor/rules/
• These appear to be historical/planning docs, but should note the architecture change

Recommendation: Update these docs or add a note that they describe the v1 architecture.

2. Missing Test Coverage Information

The PR test plan shows checkboxes but doesn't indicate:

• Whether migration was tested on actual v1 projects
• If symlinks work correctly on Windows (symlinks can be problematic)
• Whether all 4 scenarios in existing-config-detection were validated

Recommendation: Add test results or CI validation for migration scenarios.

3. Potential Windows Compatibility Concerns

Symlinks on Windows require:

• Developer mode enabled, OR
• Administrator privileges, OR
• Git configured with core.symlinks=true

Recommendation:

• Document Windows requirements in README or migration guide
• Consider fallback behavior if symlink creation fails
• Add detection for Windows and provide appropriate warnings/instructions

4. Architecture Detection Could Be More Robust

Line 204: test -L .cursor/rules && test -L CLAUDE.md && test -f AGENTS.md

This assumes all three conditions for v2, but what if:

• User manually created AGENTS.md but hasn't migrated yet?
• Symlinks were broken or deleted?
• Partial migration state exists?

Recommendation: Add edge case handling for inconsistent states.

🔍 Code Quality

Positive:

• Follows existing prompt-engineering.mdc guidelines
• XML tags used appropriately for complex sections
• Clear, goal-focused instructions for LLM execution
• Good use of examples in migration instructions

Suggestions:

• Consider adding a --dry-run option to migration to preview changes
• Migration step 3a backup could include timestamp: rules-backup-$(date +%Y%m%d-%H%M%S)

🔒 Security

No security concerns identified. The changes are structural and don't introduce:

• Credential handling
• External API calls
• Privilege escalation
• Injection vulnerabilities

⚡ Performance

No performance concerns. Symlinks are filesystem-level operations with negligible overhead.

📊 Test Coverage

The test plan exists but appears incomplete. Key gaps:

• Migration from v1 to v2 validation
• Symlink creation on different platforms
• Behavior when migration fails mid-process
• Rollback procedure testing

🎯 Final Recommendation

Approve with minor changes requested

This is high-quality architectural work that significantly improves the project's multi-tool support. The issues identified are mostly documentation completeness and edge case handling.

Must Address:

1. Update remaining .cursor/rules/ references in docs/
2. Add Windows symlink compatibility notes to README

Should Address:

3. Document migration testing results
4. Add edge case handling for inconsistent architecture states
5. Consider --dry-run option for migration

Nice to Have:

6. Timestamped backups during migration
7. Automated detection of partial migration states with recovery suggestions

Score: 8.5/10

Great architectural improvement with solid implementation. The migration support is particularly well-thought-out. With the documentation updates, this will be ready to merge.
