Implementation Reference

• src/registry.ts:1116-1133 (registration)

  Registration of the manage_notes tool in the central registry, linking to manageNotes handler and manageNotesSchema.

  manage_notes: {
    name: 'manage_notes',
    description: 'Manage session notes. Operations: add (add note with content/tags/importance), search (search by query/tagFilter), get (get by noteId), delete (remove by noteId), list (list recent with limit).',
    inputSchema: toJsonSchema(manageNotesSchema),
    handler: async (args) => {
      try {
        const result = await manageNotes(args);
        return result;
      } catch (err) {
        if (err instanceof z.ZodError) {
          const messages = err.errors.map(e => `${e.path.join('.')}: ${e.message}`).join(', ');
          return error(`Validation failed: ${messages}`);
        }
        const message = err instanceof Error ? err.message : String(err);
        return error(message);
      }
    },
  },

• src/modules/data.ts:2313-2354 (schema)

  Zod schemas defining input validation for manage_notes tool operations: add, search, get, delete, list. Combined into discriminatedUnion on 'operation' field.

  /** Add operation schema */
  const addNoteOperationSchema = z.object({
    operation: z.literal('add'),
    content: z.string().min(1, 'Content is required'),
    tags: z.array(z.string()).optional(),
    importance: ImportanceSchema.optional().default('medium'),
  });
  
  /** Search operation schema */
  const searchNoteOperationSchema = z.object({
    operation: z.literal('search'),
    query: z.string().optional(),
    tagFilter: z.array(z.string()).optional(),
  });
  
  /** Get operation schema */
  const getNoteOperationSchema = z.object({
    operation: z.literal('get'),
    noteId: z.string(),
  });
  
  /** Delete operation schema */
  const deleteNoteOperationSchema = z.object({
    operation: z.literal('delete'),
    noteId: z.string(),
  });
  
  /** List operation schema */
  const listNoteOperationSchema = z.object({
    operation: z.literal('list'),
    limit: z.number().int().min(1).optional(),
  });
  
  /** Combined schema for manage_notes using discriminatedUnion */
  export const manageNotesSchema = z.discriminatedUnion('operation', [
    addNoteOperationSchema,
    searchNoteOperationSchema,
    getNoteOperationSchema,
    deleteNoteOperationSchema,
    listNoteOperationSchema,
  ]);

• src/modules/data.ts:2535-2577 (handler)

  Primary handler function for the manage_notes tool. Parses input with manageNotesSchema, dispatches to operation-specific handlers (handleNoteAdd, handleNoteSearch, etc.), formats output using createBox, and handles errors.

  export async function manageNotes(input: unknown): Promise<{ content: { type: 'text'; text: string }[] }> {
    try {
      const parsed = manageNotesSchema.parse(input);
  
      let result: string;
  
      switch (parsed.operation) {
        case 'add':
          result = handleNoteAdd(parsed);
          break;
        case 'search':
          result = handleNoteSearch(parsed);
          break;
        case 'get':
          result = handleNoteGet(parsed);
          break;
        case 'delete':
          result = handleNoteDelete(parsed);
          break;
        case 'list':
          result = handleNoteList(parsed);
          break;
        default:
          result = createBox('ERROR', ['Unknown operation'], DISPLAY_WIDTH);
      }
  
      return { content: [{ type: 'text' as const, text: result }] };
    } catch (error) {
      const lines: string[] = [];
  
      if (error instanceof z.ZodError) {
        for (const issue of error.issues) {
          lines.push(`${issue.path.join('.')}: ${issue.message}`);
        }
      } else if (error instanceof Error) {
        lines.push(error.message);
      } else {
        lines.push('An unknown error occurred');
      }
  
      return { content: [{ type: 'text' as const, text: createBox('ERROR', lines, DISPLAY_WIDTH) }] };
    }
  }

• src/modules/data.ts:2307-2308 (helper)

  In-memory storage Map for session notes, used by all note operations.

  const notesStore = new Map<string, Note>();
