multi-objective-optimization

multi-objective-optimization is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 37 tokens per session (729 once invoked), scanned A, original, Apache-2.0.

A method for designing molecules while considering several drug properties at once, such as potency, solubility, stability, and safety. It looks for candidates that balance competing requirements instead of optimizing only one score.

In plain words
What is it for?
Use it for multi-property lead optimization, ADMET trade-off analysis, Pareto analysis, and generating molecules within defined property limits.
Why use it?
Improving one property can make another worse, so a single target score can hide important trade-offs.

About the project

synthetic-sciences/openscience is an AI workbench that carries out scientific research by reading papers, forming hypotheses, writing and running code, conducting experiments, analyzing results, and preparing reports. Researchers use it for work in machine learning, biology, physics, and chemistry with remote or local models. Catalogue add-ons extend its scientific workflows through skills and instructions.

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

multi-objective-optimization 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/pareto_optimize.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.

Multi-Objective Molecular Optimization

Overview

Real drug design is never single-objective. A useful molecule must simultaneously satisfy potency, selectivity, solubility, metabolic stability, and safety constraints. This skill implements Pareto-aware optimization that balances multiple properties without collapsing to a single weighted score.

Based on:

  • MultiMol (Yu et al., 2025): 82.3% multi-objective success rate with generate-then-rank
  • MOLLM (Ran et al., 2025): LLMs as genetic operators for multi-objective molecular design
  • DrugR (Liu et al., 2026): Multi-granular reward balancing across property groups

When to Use This Skill

  • "Improve potency while keeping hERG safe" — classic multi-objective lead optimization
  • Balancing ADMET tradeoffs — LogP vs solubility, BBB penetration vs peripheral safety
  • Pareto analysis — identify which candidates best balance competing objectives
  • Property-constrained generation — generate molecules within a defined property box

Do NOT use this skill for:

  • Single-property optimization (use molecular-optimization)
  • Property prediction without optimization (use admet-prediction)

Related Skills

  • molecular-optimization: Single-objective iterative optimization
  • admet-prediction: Compute properties used as objectives
  • admet-reasoning: Understand why properties need improvement

Installation

pip install rdkit-pypi numpy pandas

Optional

pip install matplotlib  # For Pareto front visualization

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.

multi-objective-optimization is a skill published in the GitHub repository synthetic-sciences/openscience (3,473 stars, last pushed today), licensed Apache-2.0. It adds 37 tokens to every session and 729 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.
