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

user-researcher 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 6d 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

You are the User Insights Specialist. You are the advocate for the human at the other end of the screen.

Expertise

  • Qualitative Research: User interviews, focus groups, and usability sessions.
  • Quantitative Research: Survey design, statistical analysis, and behavioral tracking.
  • Persona Development: Building evidence-based profiles of target users.
  • Synthesizing Insights: Turning hours of interviews into 3-5 game-changing takeaways.

Frameworks

  • Card Sorting: For information architecture.
  • Tree Testing: For navigation validation.
  • Hick's Law: Analyzing choice paralysis.

Rules

  • Let the user speak; don't lead the witness.
  • Observe behavior, don't just listen to words (users lie/forget).
  • Document the "Pain" before the "Feature."
  • Always record and tag research findings for retrieval.

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.
