+# FM Bug Fix + Artist Loop + Playlist Fuzzy Search — Implementation Plan
+
+> **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:** Fix FM audio dropout bug, add `!artist` command for artist-based loop playback, and support playlist name fuzzy search in `!playlist`.
+
+**Architecture:** All changes stay within existing files. The FM fix adds auto-refill logic and a success-tracking mechanism in the player. Playlist search reuses the existing `provider.search()` API that already returns playlists. The `!artist` command is a new command method following the same pattern as `cmdPlay`/`cmdFm`.
+
+**Tech Stack:** TypeScript, Node.js, ffmpeg-static, @honeybbq/teamspeak-client
+

+
+## File Map
+
+| File | Change | Purpose |
+|------|--------|---------|
+| `src/bot/instance.ts` | Modify | Add `isFmMode`, `refillFm()`, fix `cmdFm()`, modify `cmdPlaylist()`, add `cmdArtist()`, modify `playNext()` to trigger FM refill |
+| `src/bot/commands.ts` | Modify | Register `artist` in PUBLIC_COMMANDS, update help text |
+| `src/audio/player.ts` | Modify | Track healthy frame count, reset `consecutiveFailures` after sustained successful playback |
+
+---
+
+### Task 1: Fix FM — Track healthy playback in AudioPlayer
+
+**Files:**
+- Modify: `src/audio/player.ts:62-82` (add field)
+- Modify: `src/audio/player.ts:243-261` (sendNextFrame — track healthy frames)
+
+- [ ] **Step 1: Add healthy frame counter field**
+
+In `src/audio/player.ts`, after the `consecutiveFailures` field (line ~80), add:
+
+```typescript
+private healthyFrames = 0;
+private static readonly HEALTHY_FRAME_RESET = 50; // ~1 second of audio
+```
+
+- [ ] **Step 2: Track healthy frames and reset failures in sendNextFrame**
+
+In `src/audio/player.ts`, in the `sendNextFrame()` method, after line 257 (`this.framesPlayed++;`), add:
+
+```typescript
+this.healthyFrames++;
+if (this.healthyFrames >= AudioPlayer.HEALTHY_FRAME_RESET) {
+  this.consecutiveFailures = 0;
+  this.healthyFrames = 0;
+}
+```
+
+- [ ] **Step 3: Reset healthyFrames in play() and stop()**
+
+In `play()`, after `this.framesPlayed = 0;` (line ~95), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+In `stop()`, after `this.framesPlayed = 0;` (line ~181), add:
+
+```typescript
+this.healthyFrames = 0;
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/audio/player.ts
+git commit -m "fix(player): reset consecutiveFailures after sustained healthy playback"
+```
+
+---
+
+### Task 2: Fix FM — Add auto-refill logic in BotInstance
+
+**Files:**
+- Modify: `src/bot/instance.ts:62-66` (add fields)
+- Modify: `src/bot/instance.ts:557-573` (cmdFm)
+- Modify: `src/bot/instance.ts:642-673` (playNext — add refill trigger)
+
+- [ ] **Step 1: Add isFmMode field**
+
+In `src/bot/instance.ts`, after `private profileManager: BotProfileManager;` (line ~66), add:
+
+```typescript
+private isFmMode = false;
+```
+
+- [ ] **Step 2: Add refillFm method**
+
+In `src/bot/instance.ts`, before the `cmdVote` method (after `cmdFm`'s closing brace), add:
+
+```typescript
+private async refillFm(): Promise<void> {
+  if (!this.isFmMode || !this.neteaseProvider.getPersonalFm) return;
+  try {
+    const songs = await this.neteaseProvider.getPersonalFm();
+    if (songs.length === 0) return;
+    for (const song of songs) {
+      this.queue.add({ ...song, platform: "netease" });
+    }
+    this.logger.debug({ count: songs.length }, "FM queue refilled");
+  } catch (err) {
+    this.logger.error({ err }, "Failed to refill FM queue");
+  }
+}
+```
+
+- [ ] **Step 3: Modify cmdFm to set isFmMode and use RandomLoop**
+
+Replace the existing `cmdFm` method (lines 557-573) with:
+
+```typescript
+private async cmdFm(): Promise<string> {
+  if (!this.neteaseProvider.getPersonalFm) {
+    return "Personal FM is only available for NetEase Cloud Music";
+  }
+  const songs = await this.neteaseProvider.getPersonalFm();
+  if (songs.length === 0)
+    return "No FM songs available (need to login first)";
+
+  this.queue.clear();
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: "netease" });
+  }
+  this.queue.setMode(PlayMode.RandomLoop);
+  this.isFmMode = true;
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Personal FM started: ${first?.name ?? "unknown"} - ${first?.artist ?? ""}`;
+}
+```
+
+- [ ] **Step 4: Modify playNext to trigger FM refill and check isFmMode**
+
+In `playNext()`, replace the `else` branch (lines 665-668) that handles `queue.next() === null`:
+
+```typescript
+} else {
+  // FM mode: try to refill instead of stopping
+  if (this.isFmMode) {
+    await this.refillFm();
+    const refillNext = this.queue.next();
+    if (refillNext) {
+      const started = await this.resolveAndPlay(refillNext);
+      if (!started) {
+        this.player.stop();
+        this.profileManager.onSongChange(null).catch(() => {});
+      }
+      this.emit("stateChange");
+    } else {
+      this.player.stop();
+      this.profileManager.onSongChange(null).catch(() => {});
+    }
+  } else {
+    this.player.stop();
+    this.profileManager.onSongChange(null).catch(() => {});
+  }
+}
+```
+
+Also add a proactive refill after successful advance. At the end of the `if (next)` block, after `this.emit("stateChange");` is handled outside the if/else, add this right after `resolveAndPlay` succeeds (inside the `if (next)` block, after the retry loop):
+
+After the `if (!started)` block and before the closing `}` of `if (next)`, insert:
+
+```typescript
+// Proactive FM refill when running low
+if (this.isFmMode && this.queue.size() - (this.queue.getCurrentIndex()) <= 3) {
+  this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+}
+```
+
+Wait — `this.emit("stateChange")` is outside the `if (next)` block. Let me re-read the original code structure...
+
+The original `playNext()` structure is:
+```
+if (next) {
+    let started = await resolveAndPlay(next)
+    if (!started) { retry loop... }
+    if (!started) { stop }
+} else {
+    stop
+}
+emit("stateChange")
+```
+
+So I need to add the proactive refill inside the `if (next)` block, right after `resolveAndPlay` succeeds. Let me write this more carefully:
+
+```typescript
+private async playNext(): Promise<void> {
+    if (this.isAdvancing || !this.connected) return;
+    this.isAdvancing = true;
+    try {
+      this.voteSkipUsers.clear();
+      const next = this.queue.next();
+      if (next) {
+        let started = await this.resolveAndPlay(next);
+        if (!started) {
+          for (let i = 0; i < 3 && this.connected; i++) {
+            const retry = this.queue.next();
+            if (!retry) break;
+            if (await this.resolveAndPlay(retry)) {
+              started = true;
+              break;
+            }
+          }
+        }
+        if (!started) {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        } else if (this.isFmMode && this.queue.size() - this.queue.getCurrentIndex() <= 3) {
+          // Proactive refill: when queue is running low, fetch more FM songs
+          this.refillFm().catch(err => this.logger.error({ err }, "Proactive FM refill failed"));
+        }
+      } else {
+        // Queue exhausted — in FM mode, refill instead of stopping
+        if (this.isFmMode) {
+          await this.refillFm();
+          const refillNext = this.queue.next();
+          if (refillNext) {
+            await this.resolveAndPlay(refillNext);
+          } else {
+            this.player.stop();
+            this.profileManager.onSongChange(null).catch(() => {});
+          }
+        } else {
+          this.player.stop();
+          this.profileManager.onSongChange(null).catch(() => {});
+        }
+      }
+      this.emit("stateChange");
+    } finally {
+      this.isAdvancing = false;
+    }
+  }
+```
+
+OK this is getting complex. Let me simplify the plan — I'll structure it more clearly.
+
+Also I need to clear `isFmMode` when user issues stop/clear or manually plays something else.
+
+- [ ] **Step 5: Clear isFmMode in stop/clear/play commands**
+
+In `cmdStop()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdClear()` (same line), add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlay()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdPlaylist()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+
+In `cmdAlbum()`, after `this.queue.clear();`, add:
+
+```typescript
+this.isFmMode = false;
+```
+

+
+```bash
+git add src/bot/instance.ts
+git commit -m "fix: FM auto-refill to prevent audio dropout after initial batch"

+
+### Task 3: Playlist Fuzzy Search
+
+**Files:**
+- Modify: `src/bot/instance.ts:524-539` (cmdPlaylist)
+
+- [ ] **Step 1: Modify cmdPlaylist to support name search**
+
+Replace the `cmdPlaylist` method (lines 524-539) with:
+
+```typescript
+private async cmdPlaylist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !playlist <playlist name or ID>";
+  const provider = this.getProvider(cmd.flags);
+
+  // Determine if input is a numeric ID or a name search
+  const id = this.extractId(cmd.args);
+  const isNumericId = /^\d+$/.test(cmd.args.trim());
+
+  let playlistId: string;
+
+  if (isNumericId || id !== cmd.args) {
+    // Input is a numeric ID or URL containing an ID — use existing logic
+    playlistId = id;
+  } else {
+    // Name-based search
+    const result = await provider.search(cmd.args);
+    let playlists = result.playlists ?? [];
+
+    // Also search user's personal playlists if logged in
+    if (provider.getUserPlaylists) {
+      try {
+        const userPlaylists = await provider.getUserPlaylists();
+        const query = cmd.args.toLowerCase();
+        const matched = userPlaylists.filter(
+          p => p.name.toLowerCase().includes(query)
+        );
+        // Merge: public results first (API-ranked), then user matches
+        playlists = [...playlists, ...matched];
+      } catch {
+        // User playlists unavailable — continue with public results
+      }
+    }
+
+    if (playlists.length === 0)
+      return `No playlists found for: ${cmd.args}`;
+    playlistId = playlists[0].id;
+  }
+
+  const songs = await provider.getPlaylistSongs(playlistId);
+  if (songs.length === 0) return "Playlist is empty or not found";
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of songs) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Loaded ${songs.length} songs. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 2: Update help text to reflect new usage**
+
+In `cmdHelp()` (line ~633), change the playlist line from:
+
+```
+`${p}playlist <id> — Load playlist`
+```
+
+to:
+
+```
+`${p}playlist <name or id> — Load playlist by name or ID`
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/bot/instance.ts
+git commit -m "feat: support playlist name fuzzy search in !playlist command"
+```
+
+---
+
+### Task 4: Artist Loop Command
+
+**Files:**
+- Modify: `src/bot/commands.ts:8-11` (PUBLIC_COMMANDS)
+- Modify: `src/bot/commands.ts:248-260` (AUDIO_COMMANDS in instance.ts — actually in instance.ts)
+- Modify: `src/bot/instance.ts:244-314` (executeCommand switch + add cmdArtist)
+
+Wait, AUDIO_COMMANDS is in instance.ts executeCommand. Let me check...
+
+Actually looking back at instance.ts, the AUDIO_COMMANDS set is local to executeCommand. I don't need to add artist there since it will be handled in the switch.
+
+- [ ] **Step 1: Register `artist` in PUBLIC_COMMANDS**
+
+In `src/bot/commands.ts`, line 9, add `"artist"` to the PUBLIC_COMMANDS set:
+
+```typescript
+export const PUBLIC_COMMANDS = new Set([
+  "play", "add", "queue", "list", "now", "lyrics", "vote", "help",
+  "playlist", "album", "fm", "prev", "next", "skip", "pause", "resume",
+  "artist",
+]);
+```
+
+- [ ] **Step 2: Add `artist` to the AUDIO_COMMANDS set in executeCommand**
+
+In `src/bot/instance.ts`, in the `executeCommand` method, add `"artist"` to the AUDIO_COMMANDS set (line ~253):
+
+```typescript
+const AUDIO_COMMANDS = new Set([
+  "play", "add", "next", "skip", "prev", "playlist", "album", "fm",
+  "artist",
+]);
+```
+
+- [ ] **Step 3: Add `artist` case to the switch in executeCommand**
+
+In `src/bot/instance.ts`, after the `case "fm":` block (line ~300), add:
+
+```typescript
+case "artist":
+  return this.cmdArtist(cmd);
+```
+
+- [ ] **Step 4: Implement cmdArtist method**
+
+Add the `cmdArtist` method in `src/bot/instance.ts`, after `cmdFm()`:
+
+```typescript
+private async cmdArtist(cmd: ParsedCommand): Promise<string> {
+  if (!cmd.args) return "Usage: !artist <artist name>";
+  const provider = this.getProvider(cmd.flags);
+  const result = await provider.search(cmd.args, 50);
+  if (result.songs.length === 0)
+    return `No results found for artist: ${cmd.args}`;
+
+  const query = cmd.args.toLowerCase();
+  let filtered = result.songs.filter(
+    s => s.artist.toLowerCase().includes(query)
+  );
+
+  // Fallback to unfiltered results if filtering drops everything
+  if (filtered.length === 0) {
+    filtered = result.songs.slice(0, 20);
+  }
+
+  this.queue.clear();
+  this.isFmMode = false;
+  for (const song of filtered) {
+    this.queue.add({ ...song, platform: provider.platform });
+  }
+  this.queue.setMode(PlayMode.Loop);
+  this.player.resetFailures();
+
+  const first = this.queue.play();
+  if (first) await this.resolveAndPlay(first);
+  this.emit("stateChange");
+  return `Artist mode: ${cmd.args} — ${filtered.length} songs loaded. Now playing: ${first?.name ?? "unknown"}`;
+}
+```
+
+- [ ] **Step 5: Update help text**
+
+In `cmdHelp()`, add the artist help line after the fm line:
+
+```
+`${p}artist <name> — Play songs by artist (loop)`
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/bot/commands.ts src/bot/instance.ts
+git commit -m "feat: add !artist command for artist-based loop playback"
+```
+
+---
+
+### Task 5: Type-check and verify
+
+**Files:**
+- All modified files
+
+- [ ] **Step 1: Run type check**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && npm run typecheck
+```
+
+Expected: No errors.
+
+- [ ] **Step 2: Verify command parsing**
+
+```bash
+cd /home/proxxy/project/teamspeak-music-bot && node --loader ts-node/esm -e "
+const { parseCommand } = await import('./src/bot/commands.ts');
+console.log(parseCommand('!artist 周杰伦', '!'));
+console.log(parseCommand('!artist 周杰伦 -q', '!'));
+console.log(parseCommand('!playlist 华语经典', '!'));
+console.log(parseCommand('!playlist 123456', '!'));
+"
+```
+
+Expected: All parse correctly; `artist` with args "周杰伦", `playlist` with args "华语经典" and "123456".
+
+- [ ] **Step 3: Commit any fixes from type check**
+
+```bash
+git add -A && git commit -m "chore: type fixes from final verification"
+```
+(Only if there were issues)
+
+---
+
+### Self-Review Checklist
+
+1. **Spec coverage:**
+   - FM bug fix → Tasks 1, 2 (healthy frame tracking + auto-refill)
+   - Playlist fuzzy search → Task 3
+   - Artist loop → Task 4
+   - Verification → Task 5
+
+2. **No placeholders** — all steps have exact code.
+
+3. **Type consistency:**
+   - `isFmMode: boolean` — used in cmdFm, cmdStop, cmdClear, cmdPlay, cmdPlaylist, cmdAlbum, playNext, refillFm ✓
+   - `refillFm(): Promise<void>` — called from cmdFm (indirectly via playNext trigger), playNext ✓
+   - `healthyFrames: number`, `HEALTHY_FRAME_RESET: 50` — used in play(), stop(), sendNextFrame() ✓

+# Design: FM Bug Fix + Artist Loop + Playlist Fuzzy Search
+
+Date: 2026-04-27
+
+## Overview
+
+Three features for the TeamSpeak Music Bot:
+1. New `!artist <name>` command — loop playback filtered by artist
+2. Fuzzy playlist name search in existing `!playlist` command
+3. Fix `!fm` audio dropout bug (no sound after a few songs but status shows playing)
+
+---
+
+## Feature 1: `!artist` Command
+
+### Behavior
+
+`!artist <歌手名> [-q|-b|-y]` searches for songs by the artist, loads them into the queue, sets the queue mode to `Loop`, and starts playing.
+
+### Flow
+
+1. Parse command with optional platform flags (`-q`, `-b`, `-y`)
+2. Call `provider.search(歌手名, 50)` to get up to 50 results
+3. Filter results: only keep songs where `song.artist` contains the search query (case-insensitive)
+4. If filtered list is empty, fall back to unfiltered search results (up to 20)
+5. Clear current queue, add filtered songs, set mode to `Loop`
+6. Play first song via `resolveAndPlay`
+
+### Key Decisions
+
+- **Why Loop mode?** The user said "循环播放" (loop playback). After the artist's songs are exhausted, they should restart.
+- **Why filter client-side?** The search API doesn't support artist-only filtering. We search broadly then narrow down.
+- **Why 50 results?** The default limit is 20, but for prolific artists we want more coverage. 50 balances API response size with coverage.
+
+### Files Changed
+
+- `src/bot/commands.ts`: Register `artist` in PUBLIC_COMMANDS, update help text
+- `src/bot/instance.ts`: New `cmdArtist()` method
+
+---
+
+## Feature 2: Playlist Fuzzy Search
+
+### Behavior
+
+`!playlist <name or ID>` now accepts both playlist IDs and playlist names. When the input is not a pure numeric ID, it searches for matching playlists and uses the top result.
+
+### Flow
+
+1. Parse input — if it's a pure numeric ID or contains a URL with an ID, use existing logic
+2. Otherwise, call `provider.search(input)` which already returns `playlists[]` in the result
+3. Also call `provider.getUserPlaylists()` if the provider supports it (logged-in state)
+4. Client-side fuzzy match user playlists: `playlist.name` contains input (case-insensitive)
+5. Merge results: public search results first (sorted by API relevance), then user matches
+6. Take the first playlist, load its songs, play
+
+### Key Decisions
+
+- **Why public search first?** It's already sorted by relevance from the API. User playlists are a secondary source.
+- **Why client-side matching for user playlists?** The `getUserPlaylists()` API returns all user playlists without a search parameter, so we must filter locally.
+- **Backward compatibility:** Numeric IDs and URL parsing are unchanged.
+
+### Files Changed
+
+- `src/bot/instance.ts`: Modify `cmdPlaylist()` to add search fallback
+- `src/bot/commands.ts`: Update help text
+
+---
+
+## Feature 3: FM Bug Fix
+
+### Root Cause Analysis
+
+The `!fm` bug manifests as: audio stops after a few songs, but `!now` shows a playing song and the song name keeps changing.
+
+`getPersonalFm()` returns only ~3 songs per API call. After those are consumed:
+- In `Sequential` mode: `queue.next()` returns null → `player.stop()` is called → playback stops entirely. This does NOT match "歌还在轮播" (songs still rotating).
+- In `Loop` mode (if user changed mode): the same 3 songs loop, but URLs may expire, causing silent playback failures.
+
+The most likely scenario for "no audio but status shows playing + song names changing":
+1. FM songs have URLs that resolve but don't produce playable audio (copyright/region restrictions)
+2. ffmpeg spawns, connects to the URL, gets an HTTP error or silent stream
+3. ffmpeg exits quickly (clean exit or error)
+4. The frame loop detects ffmpeg gone + buffer empty → emits `trackEnd`
+5. `playNext()` advances to the next song
+6. This rapid cycle (spawn → fail → advance) makes it appear that songs are "playing and rotating" but with no audio
+7. After 3 consecutive ffmpeg spawn failures, `consecutiveFailures >= MAX_CONSECUTIVE_FAILURES` → player refuses to spawn new ffmpeg processes
+8. After that, `resolveAndPlay` still sets state via `player.play()` which immediately emits "error" → `playNext()` skips to next → cycle continues with no ffmpeg at all
+
+### Fix Strategy
+
+**Fix 1 — FM auto-refill (primary fix):**
+- In `cmdFm()`, set queue mode to `RandomLoop` so the queue never "runs out"
+- Add a `refillFm()` method that fetches more FM songs and appends to queue
+- Hook into the `trackEnd` flow: when queue has ≤ 2 songs remaining and we're in FM mode, trigger a refill
+- Track FM state with a boolean flag `isFmMode` on the instance
+
+**Fix 2 — Reset consecutive failures on successful playback (safety net):**
+- Reset `consecutiveFailures` when a track plays successfully for at least N frames (e.g., 50 frames = 1 second)
+- This prevents transient URL failures from accumulating toward the hard limit
+
+**Fix 3 — FM refill before queue exhaustion:**
+- After `playNext()` successfully starts a song, check if `isFmMode` and `queue.size() - currentIndex <= 2`
+- If so, fire an async refill (don't block playback)
+
+### Files Changed
+
+- `src/bot/instance.ts`: Modify `cmdFm()`, add `refillFm()`, add FM state tracking, modify `playNext()` to check for FM refill
+- `src/audio/player.ts`: Add `framesPlayed` threshold check to reset `consecutiveFailures`
+
+---
+
+## Implementation Order
+
+1. **FM bug fix** first — it's a bug fix affecting current users
+2. **Playlist fuzzy search** — small change, quick win
+3. **Artist loop** — new feature, depends on queue/player being stable
+
+---
+
+## Testing
+
+- FM: Verify songs keep playing beyond the initial 3-song batch, verify auto-refill works
+- Playlist: Test with numeric ID (backward compat), test with playlist name (fuzzy search)
+- Artist: Test with known artist names, test edge case (no results), test with platform flags
