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

explain 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 9d 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.

What it actually says

/explain — Code Explanation

Explain code in a clear, educational way.

Instructions

  1. Read the target from $ARGUMENTS:

    • Full file or specific function/class
    • Understand ALL the code before explaining any of it
  2. Structure the explanation:

    🎯 One-Sentence Summary

    What does this code do in plain English?

    🔗 Analogy

    Compare it to something from everyday life. E.g.: "This function is like a post office — it receives packages (requests), sorts them by destination (routes), and hands them to the right delivery truck (handler)."

    📊 Diagram

    Draw an ASCII diagram showing the flow:

    Input → [Validate] → [Transform] → [Store] → Output
               ↓                           ↓
            [Error]                    [Notify]
    

    🚶 Step-by-Step Walkthrough

    Walk through the code line by line:

    1. First, we... (line X)
    2. Then... (line Y)
    3. Finally... (line Z)

    ⚠️ Gotcha

    What's a common mistake or misconception about this code?

    🔗 Related Code

    What other files/functions does this interact with?

  3. Keep it conversational — explain like you're teaching a friend.

  4. Highlight the WHY — not just what the code does, but why it's written this way.

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.
