Automatically fetch YouTube video transcripts, generate structured summaries, and send full transcripts to messaging platforms. Detects YouTube URLs and provides metadata, key insights, and downloadable transcripts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# YouTube Summarizer Skill Automatically fetch transcripts from YouTube videos, generate structured summaries, and deliver full transcripts to messaging platforms. ## Mode Detect from context or ask: *"Quick TL;DR, full summary, or full summary with content angles?"* | Mode | What you get | Best for | |------|-------------|----------| | `quick` | 3-bullet TL;DR + single key takeaway | Fast consumption, sharing a clip | | `standard` | Full structured summary: thesis, insights, takeaway | Learning, note-taking, research | | `deep` | Full summary + chapter breakdown + content repurposing opportunities | Turning a video into a content asset | **Default: `standard`** — use `quick` if they just want the gist.

This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
