srt-ko-translator

srt-ko-translator is a skill for Claude Code, Codex from joonlab/joonlab-claudecode-setting-for-share. It costs 79 tokens per session (991 once invoked), scanned A, original, MIT.

A guide for translating English SRT subtitle files into Korean while keeping their timing information. SRT is a subtitle format that pairs each line of text with start and end times.

In plain words
What is it for?
Use it to translate English subtitles into Korean and produce a translated SRT file for video playback.
Why use it?
It avoids translating subtitle text manually while preserving the timing needed for the subtitles to remain synchronised with the video. It also prepares the result as a new SRT file.

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

srt-ko-translator 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 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/extract_subtitle_text.py, scripts/merge_translated_subtitle.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

SRT Korean Translator

Overview

This skill enables Claude to translate English SRT subtitle files into natural Korean, leveraging Claude's contextual understanding for high-quality translation that preserves timing information.

When to Use This Skill

Use this skill when users request:

  • "이 SRT 파일 한국어로 번역해줘"
  • "영어 자막을 한국어로 번역해줘"
  • "Translate this subtitle file to Korean"
  • "한글 자막 만들어줘" (with an SRT file path)

Workflow

Step 1: Extract Subtitle Text

Extract text content from the English SRT file for translation:

python3 scripts/extract_subtitle_text.py "<srt_file_path>"

Output: JSON containing:

  • texts: Array of subtitle text strings (preprocessed and grouped into sentences)
  • metadata.total_count: Number of subtitle entries
  • metadata.processed_count: Number after preprocessing

Important: The script automatically:

  • Fixes overlapping timestamps (common in auto-generated subtitles)
  • Removes short duplicate subtitles (<150ms)
  • Groups consecutive subtitles into sentence units for better translation context

Step 2: Translate with Claude

Translate each subtitle text to Korean with the following guidelines:

Translation Guidelines:

  1. Maintain natural Korean sentence structure
  2. Keep translations reasonably similar in length to fit subtitle timing
  3. Preserve technical terms appropriately (transliterate or keep original when suitable)
  4. Adapt idioms and cultural references for Korean audiences
  5. Match the original tone (formal/informal, educational/casual)
  6. Maintain the exact same number of entries as the input array

Output Format: Create a JSON array of translated strings:

[
  "첫 번째 번역된 자막",
  "두 번째 번역된 자막",
  "세 번째 번역된 자막"
]

Save this to a temporary JSON file (e.g., /tmp/translated_texts.json).

Quality Checks:

  • Verify the array length matches the original subtitle count
  • Ensure no entries are empty (unless the original was empty)
  • Check that the tone matches the original content
