# PR #648 Implementation Plan - Fix: Wrong Setup of Cursor Rules

**Date**: October 26, 2025  
**Branch**: `feature/cursor-rule-setup-648`  
**PR**: [#648 - Wrong setup of Cursor rules](https://github.com/bmad-code-org/BMAD-METHOD/pull/648)

---

## 📋 Issue Summary

The Cursor rules setup was incorrectly configured with `description:` and `globs: []` fields that were not being used and causing the rules to not apply automatically.

**Fix**: Changed `alwaysApply` from `true` to `false` and removed the empty `description` and `globs` fields so rules must be manually referenced via `@<agent-name>` in the chat window (similar to Claude Code).

**Files Changed**: 1

- `tools/installer/lib/ide-base-setup.js` (-2 lines)

**Impact**: Minimal - only removes unused fields from Cursor rule template

## 📊 Change Details

### File: `tools/installer/lib/ide-base-setup.js`

**Location**: Lines 189-197 (Cursor MDC format section)

**Before**:

```javascript
if (format === 'mdc') {
  // MDC format for Cursor
  content = '---\n';
  content += 'description: \n';
  content += 'globs: []\n';
  content += 'alwaysApply: false\n';
  content += '---\n\n';
```

**After**:

```javascript
if (format === 'mdc') {
  // MDC format for Cursor
  content = '---\n';
  content += 'alwaysApply: false\n';
  content += '---\n\n';
```

**Changes**:

- Removed: `content += 'description: \n';` (line 192)
- Removed: `content += 'globs: []\n';` (line 193)
- Kept: All other lines including `alwaysApply: false\n`

**Impact**:

- Simplifies Cursor rule template
- Rules now require manual reference via `@<agent-name>`
- More consistent with Claude Code approach
- No functional code impact

---

## 🔍 Rationale

The PR description states:

> "After testing BMAD Method in Cursor rules with the existing setup of the rule I have noticed that it was not actually using the right prompt... The fix was to change to 'Apply Manually' so the rule `@<agent-name>` has to be referenced from the chat window, similar to what you do with Claude Code."

**Why this fix works**:

1. Empty `description:` field was unused
2. Empty `globs: []` field was not filtering files
3. Removing these fields simplifies the template
4. `alwaysApply: false` makes rules manual (matching intended behavior)
5. Users reference agents via `@agent-name` directly

---

## ✅ Validation Plan

### Test 1: File Syntax ✅

- [ ] Read file to verify changes
- [ ] Check for syntax errors
- [ ] Verify formatting

### Test 2: npm validate ⏳

- [ ] Should pass all existing validations
- [ ] No new schema errors
- [ ] No dependency issues

### Test 3: npm lint ⏳

- [ ] Should pass all linting rules
- [ ] No new warnings
- [ ] Code formatting correct

### Test 4: No Regressions ⏳

- [ ] Core agents unaffected
- [ ] Core teams unaffected
- [ ] No conflicts with other code

### Test 5: Logic Verification ⏳

- [ ] Rule generation logic still works
- [ ] Other format options (claude) unaffected
- [ ] Template variables still correct

---

## 📈 Risk Assessment

**Risk Level**: ✅ **MINIMAL**

**Reasons**:

1. Only 2 lines removed from 1 file
2. Removed lines were unused/empty fields
3. Core logic unchanged
4. No API changes
5. No dependency changes
6. Backward compatible

**Impact Areas**:

- Cursor IDE rule generation (IMPROVED)
- No impact on other IDEs
- No impact on agents
- No impact on core system

---

## 🎯 Expected Outcomes

After implementing this fix:

- ✅ Cursor rules template simplified
- ✅ Rules require manual activation via `@agent-name`
- ✅ Consistent with Claude Code behavior
- ✅ No validation errors
- ✅ No lint errors
- ✅ Ready for production
