Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00102 | $0.04376 |
| Opus 5.5 | $0.00041 | $0.01750 |
| Sonnet 5.5 | $0.00020 | $0.00875 |
| Haiku 4.5 | $0.00010 | $0.00438 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 360 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
┌──────┬────────────────┬──────────────┬─────────────────────────┐
│ Book │ Title │ # Entries │ Focus │
├──────┼────────────────┼──────────────┼─────────────────────────┤
│ I │ PLANTS │ 230 entries │ Herbs, grains, spices, │

├──────┼────────────────┼──────────────┼─────────────────────────┤
│ II │ ELEMENTS │ 7 entries │ Fire, air, water, earth,│
│ │ (Elementa) │ │ wind, stars, sun/moon │
├──────┼────────────────┼──────────────┼─────────────────────────┤
│ III │ TREES │ 27 entries │ Oak, apple, willow, │

├──────┼────────────────┼──────────────┼─────────────────────────┤
│ V │ FISH │ 37 entries │ Freshwater & saltwater │
│ │ (Pisces) │ │ fish — dietary guidance │
├──────┼────────────────┼──────────────┼─────────────────────────┤
│ VI │ BIRDS │ 72 entries │ Domestic & wild birds — │
│ │ (Aves) │ │ meat properties, eggs, │
│ │ │ │ symbolic meanings │
├──────┼────────────────┼──────────────┼─────────────────────────┤
│ VII │ ANIMALS │ 45 entries │ Mammals — domestic & │
│ │ (Animalia) │ │ wild, medicinal uses of │
│ │ │ │ parts (bones, organs) │
├──────┼────────────────┼──────────────┼─────────────────────────┤
│ VIII │ REPTILES │ 16 entries │ Snakes, frogs, worms — │

├──────┼────────────────┼──────────────┼─────────────────────────┤
│ IX │ METALS │ 8 entries │ Gold, silver, iron, │
│ │ (Metalla) │ │ copper — practical and │
│ │ │ │ medicinal applications │
└──────┴────────────────┴──────────────┴─────────────────────────┘
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
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.

consult-natural-history is a skill published in the GitHub repository pjt222/agent-almanac (42 stars, last pushed 4d ago), licensed MIT. It adds 102 tokens to every session and 4,376 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
