subtitle-correction

subtitle-correction is a skill for Claude Code from sugarforever/01coder-agent-skills. It costs 73 tokens per session (2,431 once invoked), scanned A, original, MIT.

A correction guide for subtitle files in SRT format, which store timed text for videos. It fixes speech-recognition mistakes while keeping the original timings and checks technical terms in subjects such as programming and AI.

In plain words
What is it for?
Use it to proofread or correct English or Chinese SRT subtitles. Before correction, it asks for important names and terminology so those words can be recognized more accurately.
Why use it?
It reduces errors caused by automatic speech-to-text, especially when names, product names, or specialist words are transcribed incorrectly. It also makes sure corrected text stays aligned with the video.

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

subtitle-correction 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/subtitle_tool.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.

Subtitle Correction Skill

This skill corrects speech recognition errors in subtitle files while strictly preserving timeline information.

Interactive Workflow

Step 1: Request Terminology from User

IMPORTANT: Before starting any correction, ALWAYS ask the user for domain-specific terms.

Prompt the user with:

在开始修正之前,请提供一些关键术语,帮助我更准确地识别和修正语音识别错误:

1. **专有名词**:人名、品牌名、产品名等(如:Anthropic、Claude)
2. **技术术语**:框架、库、工具名称(如:LangChain、OpenAI、PyTorch)
3. **领域词汇**:行业特定词汇(如:checkpointer、middleware、runtime)
4. **其他关键词**:视频中频繁出现的重要词汇

请用逗号分隔,例如:`LangChain, Agent, OpenAI, checkpointer`

For English users:

Before I begin correction, please provide key terms to help me accurately identify speech recognition errors:

1. **Proper nouns**: Names, brands, products (e.g., Anthropic, Claude)
2. **Technical terms**: Frameworks, libraries, tools (e.g., LangChain, PyTorch)
3. **Domain vocabulary**: Industry-specific terms (e.g., checkpointer, middleware)
4. **Other keywords**: Important words that appear frequently

Please separate with commas, e.g.: `LangChain, Agent, OpenAI, checkpointer`

Step 2: Confirm Understanding

After receiving terms, confirm by:

  1. Listing the terms received
  2. Identifying the likely domain/context (AI/ML tutorial, web dev, etc.)
  3. Asking if there are any additional terms before proceeding

Example response:

收到以下术语:
- 技术框架:LangChain, LangGraph, OpenAI
- 技术概念:Agent, checkpointer, runtime

看起来这是一个 LangChain 智能体开发的教程视频。

还有其他需要补充的术语吗?如果没有,我将开始修正字幕。

Step 3: Process with Terms

Use the provided terms to:

  1. Build a mental model of expected vocabulary
  2. Identify likely speech recognition errors
  3. Apply consistent corrections throughout

When User Doesn't Provide Terms

If user says "没有" / "no" / "直接开始":

  1. Proceed with correction using built-in patterns
  2. Flag uncertain corrections for user review
  3. After completion, ask if any terms were missed

Core Workflow

  1. Read the subtitle file - Load the .srt file provided by the user
  2. Identify error patterns - Recognize common speech recognition mistakes
  3. Apply corrections - Fix errors while preserving timestamps exactly
  4. Output corrected file - Return or save based on user's context

Changes

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.
