Implementation Reference

• src/rule-engine.ts:99-115 (handler)

  Core handler function that implements the get_modification_actions tool logic by returning required post-modification actions based on the file's AI metadata.

  getActionsAfterModification(filePath: string, metadata: AIMetadata | null): string[] {
    const actions: string[] = [
      'invalidate_approvals',
      'update_last_modified',
      'add_to_changelog'
    ];
  
    if (metadata?.breakingChangesRisk === 'high') {
      actions.push('require_immediate_review');
    }
  
    if (metadata?.tests && metadata.tests.length > 0) {
      actions.push('run_tests');
    }
  
    return actions;
  }

• src/index.ts:840-845 (handler)

  MCP tool dispatch handler case that extracts input, parses file metadata, calls the rule engine, and returns the actions as JSON.

  case 'get_modification_actions': {
    const filePath = args.filePath as string;
    const fileMetadata = await this.metadataParser.parseFileMetadata(filePath);
    const actions = this.ruleEngine.getActionsAfterModification(filePath, fileMetadata);
    return { content: [{ type: 'text', text: JSON.stringify(actions, null, 2) }] };
  }

• src/index.ts:639-649 (registration)

  Tool registration entry including name, description, and input schema definition.

  {
    name: 'get_modification_actions',
    description: 'Get actions that should be taken after modifying a file',
    inputSchema: {
      type: 'object',
      properties: {
        filePath: { type: 'string', description: 'Path to the file' }
      },
      required: ['filePath']
    }
  },

• src/index.ts:642-647 (schema)

  Input schema for the get_modification_actions tool, defining the expected filePath parameter.

  inputSchema: {
    type: 'object',
    properties: {
      filePath: { type: 'string', description: 'Path to the file' }
    },
    required: ['filePath']
