TSMusicBot Phase 5: Bot Core & TS Command System

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Build BotInstance (ties TS3Client + AudioPlayer + MusicProvider together), BotManager (multi-instance lifecycle), and the TS text command parser/executor with permissions.

Architecture: BotInstance is the core unit — one TS connection, one player, one queue. BotManager creates/destroys instances and routes commands. CommandHandler parses !play, !next, etc. from TS text messages and dispatches them.

Tech Stack: TypeScript, vitest

Task 1: Command parser

Files:

• Create: src/bot/commands.ts

• Create: src/bot/commands.test.ts

• Step 1: Write the failing test

Create src/bot/commands.test.ts:

import { describe, it, expect } from 'vitest';
import { parseCommand, type ParsedCommand } from './commands.js';

describe('Command Parser', () => {
  it('parses simple command', () => {
    const result = parseCommand('!play 晴天', '!');
    expect(result).not.toBeNull();
    expect(result!.name).toBe('play');
    expect(result!.args).toBe('晴天');
    expect(result!.rawArgs).toEqual(['晴天']);
  });

  it('parses command with flags', () => {
    const result = parseCommand('!play -q 七里香', '!');
    expect(result!.name).toBe('play');
    expect(result!.flags.has('q')).toBe(true);
    expect(result!.args).toBe('七里香');
  });

  it('returns null for non-command messages', () => {
    expect(parseCommand('hello world', '!')).toBeNull();
    expect(parseCommand('', '!')).toBeNull();
  });

  it('handles custom prefix', () => {
    const result = parseCommand('/play test', '/');
    expect(result!.name).toBe('play');
    expect(result!.args).toBe('test');
  });

  it('resolves aliases', () => {
    const aliases = { p: 'play', s: 'skip', n: 'next' };
    const result = parseCommand('!p 稻香', '!', aliases);
    expect(result!.name).toBe('play');
    expect(result!.args).toBe('稻香');
  });

  it('parses command with no args', () => {
    const result = parseCommand('!pause', '!');
    expect(result!.name).toBe('pause');
    expect(result!.args).toBe('');
    expect(result!.rawArgs).toEqual([]);
  });

  it('parses vol command with number arg', () => {
    const result = parseCommand('!vol 80', '!');
    expect(result!.name).toBe('vol');
    expect(result!.args).toBe('80');
  });

  it('parses mode command', () => {
    const result = parseCommand('!mode loop', '!');
    expect(result!.name).toBe('mode');
    expect(result!.args).toBe('loop');
  });

  it('parses remove command with index', () => {
    const result = parseCommand('!remove 3', '!');
    expect(result!.name).toBe('remove');
    expect(result!.args).toBe('3');
  });
});

• Step 2: Run test to verify it fails

Run: npx vitest run src/bot/commands.test.ts Expected: FAIL

• Step 3: Write implementation

Create src/bot/commands.ts:

export interface ParsedCommand {
  name: string;         // command name (e.g., "play")
  args: string;         // everything after the command name and flags
  rawArgs: string[];    // split args
  flags: Set<string>;   // single-char flags (e.g., -q)
}

// Commands anyone can use
export const PUBLIC_COMMANDS = new Set([
  'play', 'add', 'queue', 'list', 'now', 'lyrics', 'vote', 'help',
  'playlist', 'album', 'fm', 'prev', 'next', 'skip', 'pause', 'resume',
]);

// Commands that require admin
export const ADMIN_COMMANDS = new Set([
  'stop', 'clear', 'move', 'vol', 'mode', 'follow', 'remove',
]);

export function parseCommand(
  message: string,
  prefix: string,
  aliases: Record<string, string> = {},
): ParsedCommand | null {
  const trimmed = message.trim();
  if (!trimmed.startsWith(prefix)) return null;

  const withoutPrefix = trimmed.slice(prefix.length);
  if (!withoutPrefix) return null;

  const parts = withoutPrefix.split(/\s+/);
  let name = parts[0].toLowerCase();

  // Resolve alias
  if (aliases[name]) {
    name = aliases[name];
  }

  // Parse flags and remaining args
  const flags = new Set<string>();
  const argParts: string[] = [];

  for (let i = 1; i < parts.length; i++) {
    if (parts[i].startsWith('-') && parts[i].length === 2 && /[a-zA-Z]/.test(parts[i][1])) {
      flags.add(parts[i][1].toLowerCase());
    } else {
      argParts.push(parts[i]);
    }
  }

  return {
    name,
    args: argParts.join(' '),
    rawArgs: argParts,
    flags,
  };
}

export function isAdminCommand(commandName: string): boolean {
  return ADMIN_COMMANDS.has(commandName);
}

• Step 4: Run test to verify it passes

Run: npx vitest run src/bot/commands.test.ts Expected: 9 tests PASS

• Step 5: Commit

git add src/bot/commands.ts src/bot/commands.test.ts
git commit -m "feat: add TS command parser with aliases, flags, and permission classification"

Task 4: Verify and commit Phase 5

• Step 1: Run all tests

Run: npx vitest run Expected: All tests pass

• Step 2: Verify TypeScript compilation

Run: npx tsc --noEmit Expected: No errors

• Step 3: Commit

git add -A
git commit -m "chore: Phase 5 complete — bot core (commands, instance, manager)"
