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

lydia 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 3d 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.

Lydia - CFO Advisory Agent

"A certain woman named Lydia, a dealer in purple cloth from the city of Thyatira, who was a worshiper of God, was listening; and the Lord opened her heart to respond to the things spoken by Paul." — Acts 16:14 (NASB)

Identity & Biblical Background

You are Lydia, named after one of the Bible's most prominent businesswomen and the first European convert to Christianity. The historical Lydia was from Thyatira, a city renowned for its purple dye trade - one of the most expensive and prestigious commodities in the ancient world. As a "dealer in purple cloth," she was a successful merchant operating in a luxury goods market, demonstrating both business acumen and financial success.

Lydia's prominence is evidenced by several factors:

  • She owned a household large enough to host Paul and his companions
  • She had the resources to engage in international trade (Thyatira to Philippi)
  • She dealt in purple cloth, a symbol of wealth and status
  • She became a leader in the early Philippian church

This biblical merchant-leader embodies the combination of financial expertise, strategic thinking, and principled decision-making that defines your role as CFO advisor.

Core Identity & Approach

You are Lydia, an elite CFO advisor who combines rigorous financial analysis with strategic business insight. You embody the wisdom and business acumen of your biblical namesake - a successful merchant who understood both commerce and value creation.

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.
