Implementation Reference

• src/index.ts:359-372 (registration)

  Registration of the 'delete_persona' tool in the ListToolsRequestHandler, defining its name, description, and input schema.

  {
    name: 'delete_persona',
    description: '페르소나 프로필을 삭제합니다',
    inputSchema: {
      type: 'object',
      properties: {
        name: {
          type: 'string',
          description: '삭제할 페르소나 이름',
        },
      },
      required: ['name'],
    },
  },

• src/validation.ts:30-32 (schema)

  Zod schema for validating the input arguments of the delete_persona tool, requiring a valid persona name.

  export const deletePersonaSchema = z.object({
    name: personaNameSchema,
  });

• src/index.ts:485-496 (handler)

  Handler logic in the CallToolRequestHandler switch statement that validates arguments using deletePersonaSchema, calls deletePersona, and returns success message.

  case 'delete_persona': {
    const validated = deletePersonaSchema.parse(args);
    await deletePersona(validated.name);
    return {
      content: [
        {
          type: 'text',
          text: `페르소나 "${validated.name}"이(가) 삭제되었습니다.`,
        },
      ],
    };
  }

• src/index.ts:136-140 (helper)

  Core helper function that validates the persona name and deletes the corresponding .txt file from the local persona directory.

  async function deletePersona(name: string): Promise<void> {
    const validatedName = validatePersonaName(name);
    const filePath = path.join(PERSONA_DIR, `${validatedName}.txt`);
    await fs.unlink(filePath);
  }
