CustomerNewsletter: Skill for Claude Code

.github/skills/video-matching/SKILL.md

video-matching is a skill for Claude Code, Codex from briancl2/CustomerNewsletter. It costs 77 tokens per session (1,297 once invoked), scanned A, original, MIT.

A newsletter step that finds related official videos on the VS Code and GitHub YouTube channels. YouTube is a video platform, and RSS feeds are machine-readable lists of new items.

In plain words
What is it for?
Use it after newsletter polishing to fetch recent channel videos, match them to entries by topic, and record the matches in a report.
Why use it?
It saves you from searching those channels manually for videos that explain newsletter entries. It adds matching video links directly to the assembled newsletter.

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

video-matching 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 10d 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.

Video Matching

Enrich newsletter entries with links to matching official YouTube videos from the VS Code and GitHub channels.

Quick Start

  1. Read the assembled newsletter from output/YYYY-MM_month_newsletter.md
  2. Fetch RSS feeds from VS Code and GitHub YouTube channels
  3. Match videos to newsletter entries by topic
  4. Add [Video (Xm)](URL) links to matched entries
  5. Write enriched newsletter back to output/YYYY-MM_month_newsletter.md

Inputs

  • Newsletter: output/YYYY-MM_month_newsletter.md (required)
  • YouTube RSS feeds (fetch these):
    • VS Code channel: https://www.youtube.com/feeds/videos.xml?channel_id=UCs5Y5_7XK8HLDX0SLNwkd3w
    • GitHub channel: https://www.youtube.com/feeds/videos.xml?channel_id=UC7c3Kb6jYCRj4JOHHZTxKsQ

Output

  • Enriched Newsletter: output/YYYY-MM_month_newsletter.md (overwrite in place)
  • Video Matching Report: workspace/newsletter_phase4_6_video_matches_YYYY-MM-DD.md
  • Record receipt with phase id phase4_6_video

Core Workflow

Step 1: Fetch Video Feeds

Fetch both YouTube RSS feeds. Each returns the 15 most recent videos with:

  • <title> — Video title
  • <link> — YouTube URL (format: https://www.youtube.com/watch?v=VIDEO_ID or /shorts/VIDEO_ID)
  • <published> — Publication date
  • <media:description> — Full description with chapters, links, and speaker info

Parse both feeds and build a combined video inventory.

Step 2: Filter Videos

INCLUDE videos that are:

  • Published within the newsletter's DATE_RANGE (or up to 2 weeks before/after)
  • About GitHub Copilot, VS Code, agents, MCP, security, or enterprise features
  • Full-length videos (>2 minutes) or Shorts that directly demonstrate a named feature

EXCLUDE:

  • Shorts that are generic teasers without specific feature content
  • Open Source Friday episodes about non-GitHub projects
  • Non-English content
  • General tutorials not tied to a specific feature in the newsletter

Step 3: Match Videos to Newsletter Entries

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.
