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 C, and why

learn-this scanned grade C with 2 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 13d 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.

Tapestry: Unified Content Extraction + Action Planning

This is the master skill that orchestrates the entire Tapestry workflow:

  1. Detect content type from URL
  2. Extract content using appropriate skill
  3. Automatically create a Ship-Learn-Next action plan

When to Use This Skill

Activate when the user:

  • Says "learn-this [URL]" or "learn this [URL]"
  • Says "weave [URL]"
  • Says "help me plan [URL]"
  • Says "extract and plan [URL]"
  • Says "make this actionable [URL]"
  • Says "turn [URL] into a plan"
  • Provides a URL and asks to "learn and implement from this"
  • Wants the full Tapestry workflow (extract → plan)

Keywords to watch for: learn-this, learn this, weave, plan, actionable, extract and plan, make a plan, turn into action

How It Works

Complete Workflow:

  1. Detect URL type (YouTube, article, PDF)
  2. Extract content using appropriate skill:
    • YouTube → youtube-transcript skill
    • Article → article-extractor skill
    • PDF → download and extract text
  3. Create action plan using ship-learn-next skill
  4. Save both content file and plan file
  5. Present summary to user

URL Detection Logic

YouTube Videos

Patterns to detect:

  • youtube.com/watch?v=
  • youtu.be/
  • youtube.com/shorts/
  • m.youtube.com/watch?v=

Action: Use youtube-transcript skill

Web Articles/Blog Posts

Patterns to detect:

  • http:// or https://
  • NOT YouTube, NOT PDF
  • Common domains: medium.com, substack.com, dev.to, etc.
  • Any HTML page

Action: Use article-extractor skill

PDF Documents

Patterns to detect:

  • URL ends with .pdf
  • URL returns Content-Type: application/pdf

Action: Download and extract text

Other Content

Fallback:

  • Try article-extractor (works for most HTML)
  • If fails, inform user of unsupported type

Step-by-Step Workflow

Step 1: Detect Content Type

URL="$1"

# Check for YouTube
if [[ "$URL" =~ youtube\.com/watch || "$URL" =~ youtu\.be/ || "$URL" =~ youtube\.com/shorts ]]; then
    CONTENT_TYPE="youtube"

# Check for PDF
elif [[ "$URL" =~ \.pdf$ ]]; then
    CONTENT_TYPE="pdf"

# Check if URL returns PDF
elif curl -sI "$URL" | grep -i "Content-Type: application/pdf" > /dev/null; then
    CONTENT_TYPE="pdf"

# Default to article
else
    CONTENT_TYPE="article"
fi

echo "📍 Detected: $CONTENT_TYPE"

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.
