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

file-search 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.

What it actually says

Find files and search content across directories.

Find files by name

  • By name: find . -name "*.py" -type f
  • Case-insensitive: find . -iname "*.txt" -type f
  • Modified recently: find . -name "*.rs" -mtime -1 -type f
  • Large files: find . -size +10M -type f

Search file contents

  • Grep: grep -rn "pattern" .
  • Case-insensitive: grep -rni "pattern" .
  • With context: grep -rn -C 3 "pattern" .
  • File type filter: grep -rn --include="*.py" "pattern" .
  • Ripgrep (faster): rg "pattern" or rg -t py "pattern"

Directory overview

  • Tree (if available): tree -L 2
  • Size summary: du -sh */ | sort -rh | head -20
  • File count by extension: find . -type f | sed 's/.*\.//' | sort | uniq -c | sort -rn | head -15
  • Recently modified: find . -type f -mtime -1 | head -20

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.
