    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xs-transcriber scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

音声文字起こし

音声ファイルをテキストに変換する。

絶対遵守事項

  • 長時間処理(10分以上の音声)はPID・ログ・終了コードを保存し、親process groupから分離して実行

対話フロー

Step 1: ファイル指定

「文字起こしする音声ファイルのパスを指定してください」

対応形式: mp3, wav, m4a, ogg, flac

Step 2: モデル選択

「文字起こしモデルを選択してください」

# モデル 速度 精度 用途
1 tiny 最高速 最低 テスト用
2 base 高速 標準 推奨
3 small 中速 中精度 バランス
4 medium 低速 高精度 高品質
5 large 最低速 最高 最高品質

Step 3: 実行

出力先は音声ファイルと同じディレクトリに .txt 拡張子で保存。

# 短い音声(10分以下)はフォアグラウンド
uvx transcriber_tool transcribe "[音声ファイルパス]" --model-size [モデル] --output "[出力パス].txt"

# 長い音声(10分以上)はバックグラウンド
# 以下はLinux / WSLの例。macOSではlaunchdなどservice managerを使う
TRANSCRIPTION_STATE_DIR="$(mktemp -d)"
setsid bash -lc '
  state_dir="$1"
  input="$2"
  model="$3"
  output="$4"
  echo $$ > "$state_dir/pid"
  uvx transcriber_tool transcribe "$input" --model-size "$model" --output "$output" > "$state_dir/transcription.log" 2>&1
  rc=$?
  echo "$rc" > "$state_dir/exit"
  exit "$rc"
' bash "$TRANSCRIPTION_STATE_DIR" "[音声ファイルパス]" "[モデル]" "[出力パス].txt" >/dev/null 2>&1 &

sleep 2
ps -o pid,ppid,sid,pgid,stat,etime,cmd -p "$(cat "$TRANSCRIPTION_STATE_DIR/pid")"
echo "State: $TRANSCRIPTION_STATE_DIR"

Step 4: 進行状況確認(バックグラウンド実行時)

# ログ確認
tail -f "$TRANSCRIPTION_STATE_DIR/transcription.log"

# 完了確認
cat "$TRANSCRIPTION_STATE_DIR/exit"

xangiでturnを跨ぐ場合は、処理の末尾で終了状態を保存した後に xangi tool trigger を呼ぶ。triggerを設定できない環境では、ログ・終了状態の確認をユーザーへ明示的に引き継ぎ、自動で戻ると約束しない。

Step 5: 完了報告

文字起こし完了後、以下を報告:

  • 出力ファイルパス
  • 文字数(概算)
  • 処理時間

処理時間目安

音声長 tiny base medium large
10分 30秒 1分 2-3分 5分
30分 1-2分 2-3分 5-8分 10-15分
60分 2-3分 4-6分 10-15分 20-30分

トラブルシューティング

  • transcriber_tool未インストール: 初回実行時に自動インストールされる
  • タイムアウト: setsid で分離し、PID・ログ・終了コードを保存する
  • メモリ不足: より小さいモデル(tiny/base)を使用
  • 日本語の精度が低い: モデルを large にする

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
