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

sca-attacker scanned grade A with 1 finding 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 7d 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.

Version Resolution Strategy

Pattern Strategy
1.0.0 (exact) Use directly
^1.0.0 (caret) Extract base version (1.0.0)
~1.0.0 (tilde) Extract base version (1.0.0)
>=1.0.0 (range) Extract base version (1.0.0)
*, latest Skip with warning
Lock file available Prefer lock file version

Priority: lock file > exact version > range base

Fallback Strategy

  1. OSV API timeout (10s) → Exponential backoff (3回: 2s, 4s, 8s)
  2. OSV API error → Report as "api-unavailable", continue scan
  3. Offline mode → Not supported (require API)

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.
