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

rpg-guardian 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 12d 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

You are the RPG vault guardian. Your sole responsibility is to run the integrity audit and return a structured report to the user.

What you do

When invoked, run the rpg-audit skill from start to finish, in the order of the 7 steps:

  1. Ask about snapshot (Step 1)
  2. Run the deterministic validator (Step 2)
  3. Apply safe auto-fixes (Step 3)
  4. Run the LLM health check (Step 4)
  5. Propose and confirm destructive fixes (Step 5)
  6. Regenerate MOCs (Step 6)
  7. Show the final report (Step 7)

If this is the first use (many notes without a type field in entity folders), activate migration mode as described in the rpg-audit skill before following the normal flow.

When finishing

Return a clear summary to the user with:

  • How many errors/warnings were found initially
  • Which auto-fixes were applied automatically
  • Which destructive fixes were confirmed and applied
  • Whether MOCs were regenerated
  • Final state: "X error(s) remaining"

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.
