denario

denario is a skill for Claude Code, Codex from synthetic-sciences/openscience. It costs 69 tokens per session (1,215 once invoked), scanned A, original, Apache-2.0.

A multi-agent AI system for scientific research, from examining data and forming hypotheses to writing publication-ready papers. It coordinates specialized software agents for research tasks.

In plain words
What is it for?
Use it to generate research ideas, plan methods, run computational experiments, search the literature, create visualizations, and write journal-format LaTeX papers.
Why use it?
It brings several stages of a research project into one workflow instead of requiring each stage to be handled separately.

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

denario 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.

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.

Denario

Overview

Denario is a multiagent AI system designed to automate scientific research workflows from initial data analysis through publication-ready manuscripts. Built on AG2 and LangGraph frameworks, it orchestrates multiple specialized agents to handle hypothesis generation, methodology development, computational analysis, and paper writing.

When to Use This Skill

Use this skill when:

  • Analyzing datasets to generate novel research hypotheses
  • Developing structured research methodologies
  • Executing computational experiments and generating visualizations
  • Conducting literature searches for research context
  • Writing journal-formatted LaTeX papers from research results
  • Automating the complete research pipeline from data to publication

Installation

Install denario using uv (recommended):

uv init
uv add "denario[app]"

Or using pip:

uv pip install "denario[app]"

For Docker deployment or building from source, see references/installation.md.

LLM API Configuration

Denario requires API keys from supported LLM providers. Supported providers include:

  • Google Vertex AI
  • OpenAI
  • Other LLM services compatible with AG2/LangGraph

Store API keys securely using environment variables or .env files. For detailed configuration instructions including Vertex AI setup, see references/llm_configuration.md.

Core Research Workflow

Denario follows a structured four-stage research pipeline:

1. Data Description

Define the research context by specifying available data and tools:

from denario import Denario

den = Denario(project_dir="./my_research")
den.set_data_description("""
Available datasets: time-series data on X and Y
Tools: pandas, sklearn, matplotlib
Research domain: [specify domain]
""")

2. Idea Generation

Generate research hypotheses from the data description:

den.get_idea()

This produces a research question or hypothesis based on the described data. Alternatively, provide a custom idea:

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

denario is a skill published in the GitHub repository synthetic-sciences/openscience (3,432 stars, last pushed yesterday), licensed Apache-2.0. It adds 69 tokens to every session and 1,215 once invoked, about $0.0003 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.
