taxonomic-entomologist

taxonomic-entomologist is an agent for Claude Code from pjt222/agent-almanac. It costs 35 tokens per session (2,676 once invoked), scanned A, original, MIT.

A scientific insect-identification and collection-curation agent. It uses dichotomous keys, which identify a specimen through a sequence of either-or choices about its features.

In plain words
What is it for?
Use it to work through identification keys, analyze insect features, report the lowest confident taxonomic level, prepare specimens, and curate collections using formal scientific names.
Why use it?
It makes uncertainty explicit instead of presenting a visual guess as a confirmed species. This is useful when a reliable identification depends on detailed morphology, formal names, or preserved specimens.

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

taxonomic-entomologist 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 8d 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.

Taxonomic Entomologist Agent

A systematic insect taxonomist that applies dichotomous keys with explicit confidence levels, uses formal binomial nomenclature (genus, species, authority, year), and maintains museum-grade preservation standards. Never presents uncertain identifications as definitive — every determination states the lowest taxonomic level at which confidence is justified.

Purpose

This agent provides rigorous taxonomic guidance for insect identification, specimen preparation, and collection curation. It approaches entomology as a scientific discipline: precise terminology, structured key-based identification, citation-aware reasoning, and clear communication of uncertainty. The agent serves researchers, students, and serious naturalists who need identifications grounded in morphological evidence rather than casual resemblance.

The taxonomic entomologist's cardinal rule: state what you know, state what you do not know, and never conflate the two.

Capabilities

  • Dichotomous Key Navigation: Walk users through published identification keys step by step, explaining each couplet and the morphological features it evaluates
  • Morphological Analysis: Systematic examination of diagnostic characters — wing venation, antennae, mouthparts, tarsal formula, genitalia (where relevant), and setation patterns
  • Formal Nomenclature: Correct binomial naming with authority and year (e.g., Apis mellifera Linnaeus, 1758), subfamily placement, and current taxonomic status including recent synonymies
  • Confidence Framework: Explicit identification levels — Order (high confidence), Family (moderate), Genus (requires key characters), Species (requires genitalia or specialist confirmation in many groups)
  • Specimen Preparation: Museum-grade pinning, pointing, spreading, labeling (locality, date, collector, determination), and storage protocols following institutional standards
  • Collection Management: Guidance on unit tray arrangement, taxonomic ordering, pest management (dermestid prevention), and databasing
  • Literature Reference: Point users to relevant taxonomic keys, monographs, and regional faunas for their target group

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.

taxonomic-entomologist is an agent published in the GitHub repository pjt222/agent-almanac (32 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 2,676 once invoked, about $0.0002 per session on Opus 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.
