## Intent Recognition

### Step 1: Parse User Input

Analyze query for trigger keywords and patterns:

```javascript
function recognizeIntent(userQuery) {
  const query = userQuery.toLowerCase();

  // Mode 5: Issue Reporting (highest priority)
  if (query.includes('ccw-issue') || query.includes('ccw-help') ||
      query.match(/报告.*bug/) || query.includes('功能建议')) {
    return 'ISSUE_REPORTING';
  }

  // Mode 1: Command Search
  if (query.includes('搜索') || query.includes('find') ||
      query.includes('search') || query.match(/.*相关.*命令/)) {
    return 'COMMAND_SEARCH';
  }

  // Mode 2: Recommendations
  if (query.includes('下一步') || query.includes("what's next") ||
      query.includes('推荐') || query.match(/after.*\/\w+:\w+/)) {
    return 'RECOMMENDATIONS';
  }

  // Mode 3: Documentation
  if (query.includes('参数') || query.includes('怎么用') ||
      query.includes('如何使用') || query.match(/\/\w+:\w+.*详情/)) {
    return 'DOCUMENTATION';
  }

  // Mode 4: Onboarding
  if (query.includes('新手') || query.includes('入门') ||
      query.includes('getting started') || query.includes('常用命令')) {
    return 'ONBOARDING';
  }

  // Default: Ask for clarification
  return 'CLARIFY';
}
```

## Mode 1: Command Search 🔍

### Trigger Analysis

**Keywords**: 搜索, find, search, [topic] 相关命令

**Examples**:
- "搜索 planning 命令"
- "find commands for testing"
- "实现相关的命令有哪些"

### Processing Flow

```
1. Extract Search Parameters
   ↓
2. Determine Search Type
   ├─ Keyword Search (in name/description)
   ├─ Category Search (workflow/cli/memory/task)
   └─ Use-Case Search (planning/implementation/testing)
   ↓
3. Query Appropriate Index
   ├─ Keyword → all-commands.json
   ├─ Category → by-category.json
   └─ Use-Case → by-use-case.json
   ↓
4. Filter and Rank Results
   ↓
5. Format Response
   ├─ List matching commands
   ├─ Show key metadata (name, description, args)
   └─ Suggest related commands
```

### Implementation

```javascript
async function searchCommands(query, searchType) {
  let results = [];

  switch (searchType) {
    case 'keyword':
      // Load all-commands.json
      const allCommands = await readIndex('all-commands.json');
      results = allCommands.filter(cmd =>
        cmd.name.toLowerCase().includes(query.toLowerCase()) ||
        cmd.description.toLowerCase().includes(query.toLowerCase())
      );
      break;

    case 'category':
      // Load by-category.json
      const byCategory = await readIndex('by-category.json');
      const category = extractCategory(query); // e.g., "workflow"
      results = flattenCategory(byCategory[category]);
      break;

    case 'use-case':
      // Load by-use-case.json
      const byUseCase = await readIndex('by-use-case.json');
      const useCase = extractUseCase(query); // e.g., "planning"
      results = byUseCase[useCase] || [];
      break;
  }

  // Rank by relevance
  results = rankResults(results, query);

  // Add related commands
  results = await enrichWithRelated(results);

  return results;
}
```

  const relationships = await readIndex('command-relationships.json');

  // Get relationship data
  const cmdData = relationships[currentCommand];

  if (!cmdData) {
    return defaultRecommendations();
  }

  // Primary next steps
  const nextSteps = cmdData.next_steps || [];

  // Alternative related commands
  const alternatives = cmdData.related_commands || [];

  // Build recommendations
  const recommendations = {
    primary: await enrichCommand(nextSteps[0]),
    alternatives: await enrichCommands(alternatives),
    workflow_pattern: findWorkflowPattern(currentCommand),

    auto_context: gatherAutoContext()
  });

  // Save
  const outputPath = `templates/.generated/${issueType}-${Date.now()}.md`;
  await writeFile(outputPath, filledTemplate);

  return {
    template: filledTemplate,
    file_path: outputPath,
    instructions: 'Copy content to GitHub Issues or use: gh issue create -F ' + outputPath
  };
}
```

## Error Handling

### Not Found
```javascript
if (results.length === 0) {
  return {
    message: 'No commands found matching your query.',
    suggestions: [
      'Try broader keywords',
      'Browse by category: workflow, cli, memory, task',
      'View all commands: essential-commands.json',
      'Need help? Ask: "CCW-help"'
    ]
  };
}
```

### Ambiguous Intent
```javascript
if (intent === 'CLARIFY') {
  return await askUserQuestion({
    question: 'What would you like to do?',
    options: [
      'Search for commands',
      'Get recommendations for next steps',
      'View command documentation',
      'Learn how to get started',
      'Report an issue or get help'
    ]
  });
}
```

---

## Optimization Strategies

### Caching
```javascript
// Cache indexes in memory after first load
const indexCache = new Map();

async function readIndex(filename) {
  if (indexCache.has(filename)) {
    return indexCache.get(filename);
  }

  const data = await readFile(`index/${filename}`);
  const parsed = JSON.parse(data);
  indexCache.set(filename, parsed);
  return parsed;
}
```

### Lazy Loading
```javascript
// Only load full command files when needed
// Use index metadata for most queries
// Read command file only for Mode 3 (Documentation)
```
