## Issue Reference Integration

The skill now integrates with Gitea client to suggest issue references:

### Automatic Issue Suggestions (NON-BLOCKING)

When you run `git commit`, the pre-commit hook will:
1. **Check for open issues in Gitea** (if available)
2. **Display issue suggestions** (helpful information only)
3. **Suggest reference formats** (optional guidance)

**Important:** This is **completely non-blocking** - you can always commit with any message!

The suggestions are just helpful reminders, never requirements.

**Example Output:**
```
🔍 Checking for relevant issues...
📋 Found 1 open issue(s):
  #2: Optimize Gitea Workflow for Main Branch
    https://gitea.arcodange.lab/arcodange/dance-lessons-coach/issues/2

💡 Suggested commit message formats:
  - closes #<number>      (when issue is fully resolved)
  - fixes #<number>       (when fixing a bug)
  - resolves #<number>    (when resolving an issue)
  - related to #<number>   (when work is related)
  - see #<number>         (when referencing for context)

Example: ✨ feat: implement workflow (closes #2)
```

### Issue Reference Formats

**Standard Formats:**
- `closes #2` - When issue is fully resolved
- `fixes #5` - When fixing a specific bug
- `resolves #3` - When resolving an issue
- `related to #2` - When work is related
- `see #4` - When referencing for context

**GitHub/Gitea Compatible:**
These formats are recognized by both GitHub and Gitea to automatically close issues.

## Git Hooks for Code Quality

The project includes Git hooks that automatically run before commits to ensure code quality:

### Pre-commit Hook (NON-BLOCKING)
- **Location**: `.git/hooks/pre-commit`
- **Automatically runs**:
  - **Issue reference suggestions** (helpful but optional)
  - `go mod tidy` - Cleans up and organizes Go dependencies
  - `go fmt` - Formats staged Go files according to standards
  - Auto-adds modified files to the commit

**Behavior:**
- ✅ **Always allows commits** - never blocks you
- ✅ **Shows helpful suggestions** - you can ignore them
- ✅ **Formats Go code automatically** - but only if you're in a Go project
- ✅ **Gracefully handles errors** - continues even if something fails

### How It Works

```bash
# When you commit:
git add .
git commit -m "✨ feat: add new feature"

# The hook automatically:
1. Runs `go mod tidy`
2. Runs `go fmt` on all Go files
3. Adds any modified files to your commit
4. Allows commit if successful
```

### Benefits
- Ensures consistent code formatting
- Maintains clean dependency management
- Prevents common Go code issues
- Runs automatically - no manual steps needed

## Best Practices

### Commit Message Structure
```
<gitmoji> <type>: <description>

<optional body with details>

<optional footer with references>
```

### Examples

**Simple commit:**
```
✨ feat: add skill_creator framework
```

**Detailed commit:**
```
✨ feat: implement BDD testing with Godog

- Add features/greet.feature and features/health.feature
- Implement step definitions in pkg/bdd/steps/
- Create hybrid in-process test server
- Add comprehensive documentation

```

**Complex commit:**
```
🧪 test: add comprehensive BDD test suite

- Implement greet service scenarios
- Add health endpoint validation
- Create test server on port 9191
- Ensure no undefined/pending steps

Resolves: #42
Ref: AGENTS.md

```

## Validation

### Check Commit Message Format
```bash
# Verify gitmoji is present
echo "$commit_message" | grep -E "^[[:space:]]*[🎨✨🐛📝🔧♻️🚀🔒📦🔥🐧🍎🪟🤖🧪📈🌐⚡]"

# Verify type: description format
echo "$commit_message" | grep -E "^[🎨✨🐛📝🔧♻️🚀🔒📦🔥🐧🍎🪟🤖🧪📈🌐⚡][[:space:]]+[a-z_]+:"
```

### Common Validation Issues

| Issue | Cause | Solution |
|-------|-------|----------|
| Missing gitmoji | No emoji at start | Add appropriate gitmoji from reference |
| Wrong type | Type doesn't match emoji | Use correct type from reference table |
| Missing colon | No colon after type | Add colon: `feat:` not `feat` |
| Long first line | First line > 50 chars | Keep first line concise, add details in body |

## Git Hooks Reference

### Hook Location
```bash
.git/hooks/pre-commit
```

### Hook Content
```bash
#!/bin/sh

# dance-lessons-coach pre-commit hook
# Runs go mod tidy and go fmt before allowing commits

echo "Running pre-commit hooks..."

# Check if we're in a Go project
if [ ! -f "go.mod" ]; then
    echo "Not a Go project, skipping hooks"
    exit 0
fi

# Run go mod tidy
echo "Running go mod tidy..."
go mod tidy
if [ $? -ne 0 ]; then
    echo "ERROR: go mod tidy failed"
    exit 1
fi

# Check if go.mod or go.sum were modified
if git diff --cached --name-only | grep -qE '(go\.mod|go\.sum)'; then
    echo "go.mod or go.sum changed, adding to commit..."
    git add go.mod go.sum
fi

# Run go fmt on all Go files
echo "Running go fmt..."
GOFILES=$(find . -name '*.go' -not -path "./vendor/*" -not -path "./.git/*")
if [ -n "$GOFILES" ]; then
    gofmt -w $GOFILES
    if [ $? -ne 0 ]; then
        echo "ERROR: go fmt failed"
        exit 1
    fi
    
    # Add formatted files to commit
    git add $GOFILES
fi

echo "Pre-commit hooks completed successfully"
exit 0
```

### Customization

To modify the hook:
```bash
# Edit the hook
nano .git/hooks/pre-commit

# Make it executable (if needed)
chmod +x .git/hooks/pre-commit
```

### Disabling Hooks

To skip hooks for a single commit:
```bash
git commit --no-verify -m "✨ feat: add new feature"
```

## Troubleshooting

### Finding the Right Gitmoji
```bash
# Search for appropriate gitmoji
grep "feature\|new" .vibe/skills/commit_message/SKILL.md
# Result: ✨ :sparkles: feat - New feature
```

### Commit Message Too Long
```bash
# Split into concise first line + detailed body
git commit -m "✨ feat: add BDD framework" -m "- Implement Godog testing" -m "- Add greet/health features" -m "- Create test server"
```

### Multiple Changes in One Commit
```bash
# Use comprehensive description
git commit -m "♻️ refactor: improve BDD implementation" -m "- Update step patterns to match Godog exactly" -m "- Add JSON response validation" -m "- Implement server verification" -m "- Update all templates and documentation"
```

### Git Hooks Issues

**Hook fails with error:**
```bash
# Check the specific error message
# Fix the underlying issue (e.g., Go syntax error, dependency issue)
# Commit again
```

**Hook runs too slow:**
```bash
# The hooks are optimized to only process necessary files
# If performance is an issue, check for very large Go files
# Consider splitting large files into smaller modules
```

**Need to bypass hooks temporarily:**
```bash
# Use --no-verify flag
git commit --no-verify -m "⚡ chore: quick fix"

# Remember to run hooks manually later
go mod tidy
gofmt -w .
```
