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

cross-examination 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 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.

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

Cross-Examination

Probes defender responses for inconsistencies and logical gaps.

Execution

Subagent — spawned via subagent-spawning/spawn-agent.

Why Subagent

Cross-examination requires fresh analytical perspective on the defense — isolated context prevents anchoring to either attack or defense framing.

Input

  • defenses: Structured defenses from debate-defender
  • attacks: Original attacks that prompted the defenses
  • artifact: The artifact being debated (for reference)

Output

  • probes: List of follow-up questions targeting defense weaknesses
  • inconsistencies: Contradictions found within or between defenses
  • unsupported_claims: Defense claims lacking evidence
  • verdict_suggestion: Whether defense held up under examination

Budget

One unit = one cross-examination pass per round.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP When to use
spawn-agent Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
