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

blog.create_til 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 yesterday.

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.

What it actually says

Goal

  • Write a concise, engaging "Today I Learned" (TIL) blog post on the user's topic

Workflow

Structure

  1. Title
  2. What I Learned
  3. Why It Matters
  4. Example / Demonstration
  5. Key Takeaways
  6. References or Further Reading
  • The post should:
    • Start with a short intro: what I learned and why it caught my attention
    • Explain the concept in simple language for engineers and curious readers
    • Include a practical example, code snippet, or real-world use case if relevant
    • Highlight surprising insights, common misconceptions, or lessons learned
    • End with key takeaways and actionable advice for further exploration

Use Front Matter and TL;DR

  • Add front matter as in .claude/skills/blog.rules.md ## Front Matter (YAML)
  • Add TL;DR as in .claude/skills/blog.rules.md ## TL;DR Section

Beautify

  • Run a command to format the code for proper visualization 
    > prettier --tab-width 4 --prose-wrap always --print-width 80 -w <FILE>

Conventions

Tone

  • Conversational and reflective
  • Technical but accessible
  • Curious and educational

Length

  • Keep the post between 500 and 1000 words. Favor clarity and practical value over exhaustive coverage

Formatting Rules

  • Write using bullet points

  • Follow the rules in:

    • .claude/skills/blog.rules.md
    • .claude/skills/markdown.rules.md
    • .claude/skills/text.rules.md

Verification

  • Confirm front matter and a TL;DR are present per .claude/skills/blog.rules.md
  • Confirm the post is between 500 and 1000 words
  • Confirm prettier ran without errors

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.
