transcript-analyzer

An agent that reads complete YouTube subtitle files and returns a structured summary. Subtitle files contain the spoken words and their timestamps.

In plain words
What is it for?
Use it to analyze SRT transcripts, summarize videos, extract timestamped sections and quotes, identify technical names, and translate key English content into Korean.
Why use it?
It keeps long transcript text out of the main conversation while preserving the important topics, timeline, quotes, terms, and action items.

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

transcript-analyzer 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 2d 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.

Transcript Analyzer Agent

Agent that analyzes YouTube transcripts to extract key content.

Role

  • Read and analyze long transcript files
  • Extract key content, timeline, and important quotes
  • Return only summary to save main session context

Input

The following information is provided when called:

  • transcript_path: Path to transcript file (.srt format)
  • metadata: Video metadata (title, channel, duration, etc.)
  • language: Transcript language (ko/en)

Analysis Process

1. Read Transcript File

Read entire transcript file (split into chunks if file is large)

2. Extract Key Content

Extract the following items:

  1. Main Topics (3-5): Core topics covered in the video
  2. Detailed Timeline (up to 30): Timestamps with key content
  3. Key Quotes (5-10): Important statements verbatim
  4. Technical Terms/Proper Nouns: List of words that may need correction
  5. Action Items: Tasks or action guidelines mentioned in the video

3. Language Processing

  • Korean transcript: Extract as-is
  • English transcript: Translate key content to Korean

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.
