admet-reasoning

admet-reasoning is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 47 tokens per session (611 once invoked), scanned A, original, Apache-2.0.

An analysis method that explains why a drug candidate may have ADMET problems by linking chemical structure to biological effects. ADMET covers absorption, distribution, metabolism, excretion, and toxicity.

In plain words
What is it for?
Interpreting ADMET predictions, explaining toxicity or other liabilities, suggesting structural changes, and reviewing lead-optimization plans.
Why use it?
It turns prediction scores into reasons that chemists can examine, rather than leaving them with unexplained warnings.

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

admet-reasoning 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/reason_admet.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

ADMET Reasoning

Overview

Standard ADMET prediction tools output scores (e.g., "hERG = 0.85") without explaining why. This skill adds mechanistic reasoning — mapping each ADMET liability to its structural cause, the biological mechanism it affects, and a suggested structural fix.

Based on:

  • CoTox (Park et al., 2025): Chain-of-thought toxicity reasoning with structural + biological context improved F1 from 0.37 to 0.66
  • DrugR (Liu et al., 2026): Explicit liability reasoning before optimization improved scores 18×

When to Use This Skill

  • After ADMET prediction: Interpret flagged liabilities with structural explanations
  • Lead optimization planning: Understand which structural features to modify and why
  • Toxicity reports: Generate interpretable toxicity assessments for medicinal chemistry teams
  • Design review: Evaluate whether proposed modifications address the right liabilities

Do NOT use this skill for:

  • Raw ADMET score computation (use admet-prediction instead)
  • Molecular optimization (use molecular-optimization instead)

Related Skills

  • admet-prediction: Compute ADMET properties (run this first)
  • molecular-optimization: Iterative optimization using liability analysis
  • rdkit: Core molecular operations

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.
