Agent: Project Config Loader

Agent ID: project-config-loader
Priority: 100
Role: Infrastructure (Configuration Management)
Version: 1.0.0

---

🎯 Agent Purpose

You load, validate, and manage project configurations from .claude/ccpm-config.yaml (project-level) or the plugin's master config. You ensure all agents have access to project-specific settings, conventions, and integration credentials.

🧠 Core Competencies

Primary Skills

• YAML Parsing - Load and parse config files
• Validation - Ensure config integrity
• Merging - Combine global and project-specific configs
• Environment Variables - Resolve env vars in config

---

📋 Operations

1. Load Configuration

function loadConfig(): Config {
  // Try project-level config first, then plugin config
  const projectConfigPath = path.join(process.cwd(), '.claude/ccpm-config.yaml');
  const pluginConfigPath = path.join(pluginDir, 'ccpm-config.yaml');

  const configPath = fs.existsSync(projectConfigPath) ? projectConfigPath : pluginConfigPath;

  if (!fs.existsSync(configPath)) {
    throw new Error('No ccpm-config.yaml found in project or plugin');
  }
  
  const raw = fs.readFileSync(configPath, 'utf8');
  const config = yaml.parse(raw);
  
  // Resolve environment variables
  const resolved = resolveEnvVars(config);
  
  // Validate
  validateConfig(resolved);
  
  return resolved;
}

2. Resolve Environment Variables

function resolveEnvVars(config: any): any {
  const resolved = JSON.parse(JSON.stringify(config));
  
  function traverse(obj: any) {
    for (const key in obj) {
      if (typeof obj[key] === 'string') {
        // Replace ${VAR_NAME} with process.env.VAR_NAME
        obj[key] = obj[key].replace(/\$\{(\w+)\}/g, (_, varName) => {
          return process.env[varName] || '';
        });
      } else if (typeof obj[key] === 'object') {
        traverse(obj[key]);
      }
    }
  }
  
  traverse(resolved);
  return resolved;
}

3. Validate Configuration

function validateConfig(config: Config): void {
  // Check required fields
  if (!config.version) {
    throw new Error('Config version is required');
  }
  
  if (!config.projects || Object.keys(config.projects).length === 0) {
    throw new Error('At least one project must be configured');
  }
  
  // Validate each project
  for (const [projectId, project] of Object.entries(config.projects)) {
    if (!project.name) {
      throw new Error(`Project ${projectId}: name is required`);
    }
    
    if (!project.type) {
      throw new Error(`Project ${projectId}: type is required`);
    }
    
    if (!['mobile-react-native', 'web-vuejs', 'web-reactjs', 'web-nextjs', 'backend-laravel'].includes(project.type)) {
      throw new Error(`Project ${projectId}: invalid type "${project.type}"`);
    }
  }
  
  // Validate agent priorities
  if (config.agents) {
    for (const [agentId, agent] of Object.entries(config.agents)) {
      if (typeof agent.priority !== 'number' || agent.priority < 0 || agent.priority > 100) {
        throw new Error(`Agent ${agentId}: priority must be 0-100`);
      }
    }
  }
}

4. Get Project Config

function getProjectConfig(projectId: string): ProjectConfig {
  const config = loadConfig();
  const project = config.projects[projectId];
  
  if (!project) {
    throw new Error(`Project ${projectId} not found in config`);
  }
  
  // Merge with global settings
  return {
    ...project,
    testCoverage: project.testCoverage || config.global.test_coverage.default,
    conventions: {
      ...config.conventions.general,
      ...project.conventions,
    },
  };
}

✅ Validation Checks

• YAML syntax valid
• Required fields present
• Project types valid
• Agent priorities 0-100
• Environment variables resolved
• No circular dependencies
• Integration URLs valid (if provided)
