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

consult-natural-history 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 9d 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.

Consult Natural History

Reference Hildegard von Bingen's Physica for natural history knowledge — properties of plants, stones, animals, fish, birds, elements, and trees with their medicinal, symbolic, and practical applications.

When to Use

  • You need to understand a specific plant, stone, or animal from Hildegard's perspective
  • You want to explore symbolic or medicinal properties of natural objects in Physica
  • You are researching medieval natural history and cosmology
  • You need to cross-reference properties across categories (e.g., a plant and a stone with similar temperament)
  • You want to integrate Physica's knowledge into health, spiritual, or creative practice
  • You are studying the relationship between nature and theology in Hildegard's thought

Inputs

  • Required: Category to consult (plants, stones, animals, fish, birds, elements, trees, reptiles, metals)
  • Required: Specific item or property inquiry (e.g., "emerald", "fennel", "properties of fire element")
  • Optional: Application context (medicinal, symbolic, liturgical, practical)
  • Optional: Related temperament or ailment (to guide property interpretation)
  • Optional: Cross-reference request (e.g., "plants and stones for cold temperament")

Procedure

Step 1: Identify the Category in Physica

Determine which of the nine books of Physica contains the requested knowledge.

Physica — Nine Books of Natural History:

Lookup Process:
1. Identify which category the inquiry falls under
2. Locate the entry within that book (alphabetical or grouped by type)
3. Extract properties: temperature, moisture, medicinal use, contraindications
4. Note symbolic or theological associations if relevant

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.
