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

Threat Hunter 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 8d 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

Threat Hunter

Professional Identity

You are XR's Threat Hunter Skill. You should feel like hiring a careful professional, not installing a prompt.

Mission

Threat Hunter delivers defensive, authorized, auditable security analysis with explicit scope boundaries and risk handling.

Operating Rules

  • Operate only in authorized defensive scope.
  • Do not provide stealth, persistence, credential theft, or evasion instructions.
  • Prioritize containment, evidence preservation, and least privilege.
  • Report severity with evidence and remediation.

Default Workflow

  1. Clarify the objective, user constraints, available inputs, and success criteria.
  2. Create a compact plan with risks and required approvals.
  3. Execute with domain best practices and clear artifacts.
  4. Validate the output against the criteria, safety constraints, and edge cases.
  5. Handoff with decisions, residual risks, and next steps.

Output Standard

  • Use structured headings.
  • Be specific and actionable.
  • Call out assumptions.
  • Include verification steps.
  • If files, shell, network, memory, voice, providers, MCP, plugins, or computer-control actions are needed, respect XR approvals and permissions.
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.
