Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00113 | $0.01536 |
| Opus 5 | $0.00056 | $0.00768 |
| Sonnet 5 | $0.00023 | $0.00307 |
| Haiku 4.5 | $0.00011 | $0.00154 |
Grade A, and why
whisper-subtitle 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 7d 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.

Whisper Subtitle Generator
Generate TXT or SRT subtitle files from audio or video files using mlx-whisper with the whisper-medium-mlx model. Supports batch processing (sequential due to MLX GPU constraints).
Quick Start
# Single file (default: TXT format, output to ~/Downloads)
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "<input_file>"
# Multiple files (batch processing - sequential)
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "<file1>" "<file2>" "<file3>"
Default Settings
| Setting | Default Value |
|---|---|
| Output directory | ~/Downloads |
| Output format | txt |
| Output filename | {original_filename}_transcript.txt or .srt |
| Model | mlx-community/whisper-medium-mlx |
Important Note
MLX GPU Constraint: mlx-whisper uses Apple MLX (Metal GPU) which doesn't support parallel access from multiple threads. Batch processing is performed sequentially (one file at a time) to avoid GPU conflicts and crashes.
Workflow
1. Identify Input File(s)
Supported formats:
- Audio: mp3, wav, m4a, flac, ogg, aac
- Video: mp4, mkv, mov, avi, webm
2. Determine Output Settings
- Format: Ask user if they want TXT (default) or SRT
- Output directory: Use user-specified path, or default
~/Downloads - Custom filename: If user specifies, use
-noption (single file only)
3. Run Subtitle Generation
Single File
# Basic (TXT to ~/Downloads)
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "/path/to/video.mp4"
# SRT format
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "/path/to/video.mp4" -f srt
# Custom output directory
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "/path/to/video.mp4" -o "/custom/path"
# Custom filename
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "/path/to/video.mp4" -n "my_custom_name"
# Specify language
python3 ~/.claude/skills/whisper-subtitle/scripts/generate_subtitle.py "/path/to/video.mp4" -l en
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

whisper-subtitle is a skill published in the GitHub repository joonlab/joonlab-claudecode-setting-for-share (10 stars, last pushed 1mo ago), licensed MIT. It adds 113 tokens to every session and 1,536 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
