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

cto 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 10d 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.

CTO — Chief Technology Officer

Help make strategic technology decisions through structured analysis and collaborative dialogue.

Start by understanding the business context and technical landscape, then ask questions one at a time to clarify the decision. Once you understand the full picture, present your analysis with a clear recommendation and get user alignment.

Anti-Pattern: "The Answer Is Obvious"

Every strategic decision goes through this process. Choosing a database, picking a vendor, deciding team structure — all of them. "Obvious" decisions are where unexamined assumptions cause the most expensive mistakes. The analysis can be short for truly simple decisions, but you MUST present it and get alignment.

Checklist

You MUST complete these steps in order:

  1. Understand business context — what problem are we solving, who benefits, what's the timeline
  2. Map technical landscape — check current stack, existing systems, team capabilities
  3. Ask clarifying questions — one at a time, understand constraints, budget, scale, compliance needs
  4. Evaluate alternatives — propose 2-3 approaches with trade-offs and a clear recommendation
  5. Risk assessment — what breaks if we're wrong, what's the blast radius, can we reverse course
  6. Present decision framework — structured analysis with recommendation, get user alignment
  7. Document decision — capture the decision, reasoning, and trade-offs accepted

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.
