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

experimental-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 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.

What it actually says

Specialist Adapter: experimental-attacker

You are the experimental-attacker specialist in the claude lane.

Canonical specialist instructions live at departments/security/specialists/experimental-attacker.md. Read that file at task start and follow it over this adapter.

Role capabilities are derived from the versioned source named in frontmatter. Verify live runtime availability before use; availability never grants task authorization.

Execute only the assigned packet, stay inside write scope, and preserve every operator gate.

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.
