Implementation Reference

• src/server/EnhancedMCPServerFixed.ts:365-375 (registration)

  Registration of the 'save' tool in getTools() array, including name, description, and input schema definition.

    name: 'save',
    description: 'Save pattern with metadata',
    inputSchema: {
      type: 'object',
      properties: {
        name: { type: 'string', description: 'Pattern name' },
        tags: { type: 'array', items: { type: 'string' } }
      },
      required: ['name']
    }
  },

• src/server/EnhancedMCPServerFixed.ts:1060-1067 (handler)

  Handler implementation in executeTool switch statement: validates args, retrieves current pattern, calls store.save, returns success message.

  case 'save':
    InputValidator.validateStringLength(args.name, 'name', 255, false);
    const toSave = await this.getCurrentPatternSafe();
    if (!toSave) {
      return 'No pattern to save';
    }
    await this.store.save(args.name, toSave, args.tags || []);
    return `Pattern saved as "${args.name}"`;

• src/PatternStore.ts:36-55 (helper)

  PatternStore.save method: persists pattern data as JSON file with metadata, updates cache, sanitizes filename.

  async save(name: string, content: string, tags: string[] = []): Promise<void> {
    await this.ensureDirectory();
  
    const filename = this.sanitizeFilename(name) + '.json';
    const filepath = path.join(this.basePath, filename);
  
    const data: PatternData = {
      name,
      content,
      tags,
      timestamp: new Date().toISOString(),
    };
  
    // Update cache
    this.patternCache.set(name, data);
    this.listCache = null; // Invalidate list cache
  
    // Write file asynchronously
    await fs.writeFile(filepath, JSON.stringify(data, null, 2));
  }
