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

tlp-guide 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.

Traffic Light Protocol (TLP) v2.0

Every intelligence output from this platform MUST have a TLP designation. This is enforced by platform rules and validated by hooks.

TLP Definitions

TLP:RED — Named Recipients Only

When to use: Information that would cause significant harm if shared beyond the named recipients. Sources may face risk.

  • Share with: Only the named recipients, in person or via secure channels
  • Do NOT share with: Anyone not explicitly named, even within the same organisation
  • Examples: Active zero-day exploitation details shared to a specific CISO; source-identifying intelligence; ongoing law enforcement operation details

TLP:AMBER+STRICT — Organisation Only

When to use: Information that requires support to be effectively acted upon, limited to the recipient's organisation only.

  • Share with: Members of the recipient's own organisation on a need-to-know basis
  • Do NOT share with: External parties, clients, partners, or affiliated organisations
  • Examples: Targeted threat intelligence specific to one organisation's infrastructure; internal investigation findings

TLP:AMBER — Organisation + Need-to-Know

When to use: Information that requires support to be effectively acted upon, and may be shared with clients/partners on a need-to-know basis.

  • Share with: Members of the recipient's organisation AND their clients/partners who need the information to protect themselves
  • Do NOT share with: The general public, social media, or parties without a clear need-to-know
  • Examples: Sector-specific threat briefings shared with ISAC members; IOCs for active campaigns affecting a supply chain

TLP:GREEN — Community

When to use: Information useful for awareness within a broader community but not for public disclosure.

  • Share with: The wider community (sector peers, security community) but not via publicly accessible channels
  • Do NOT share with: The general public, social media, public blogs, or news outlets
  • Examples: General threat landscape updates shared at closed conferences; new TTP descriptions shared within an ISAC

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.
