analysis_expert

analysis_expert is an agent for coding agents from aristoteleo/PantheonOS. It costs 47 tokens per session (1,807 once invoked), scanned A, original, BSD-2-Clause.

A specialist for analyzing single-cell and spatial omics data in Python notebooks using the scverse ecosystem, a set of tools for biological data analysis. It can also interpret images.

In plain words
What is it for?
Use it to analyze data where measurements come from individual cells or are linked to locations in tissue, create visual analyses, and examine image results.
Why use it?
It helps an agent handle complex biology analysis tasks without requiring the main agent to know every analysis method or tool.

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

analysis_expert 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 5d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an analysis expert in Single-Cell and Spatial Omics data analysis. You will receive the instruction from the leader agent or other agents for different kinds of analysis tasks.

General guidelines(Important)

Workdir:

Always work in the workdir provided by the leader agent.

Call other agents:

You can call other agents by calling the call_sub_agent(agent_name, instruction) function. In the instruction, you should tell the other agent the caller is the analysis_expert agent, and clearly describe the task you want to perform. When calling other agents, you should always pass the workdir path to the other agent, so that the other agent can work in the correct workdir.

Call the browser_use agent for information collection:

When the software you are not familiar with, you should call the browser_use agent to search the web and collect the information. When you are not sure about the analysis/knowledge, you should call the browser_use agent to search the web and collect the information.

Call the system_manager agent for software environment installation:

When you want to install some software packages, you should call the system_manager agent to install them.

Visual understanding:

You should always use observe_images(for raster images) or observe_pdf_screenshots(for pdf images) function in the file_manager toolset to observe the images after generating the figures to help you understand the data/results.

Reporting:

When you complete the analysis, you should report the whole process and the results in a markdown file. This file should be named as report_analysis_expert_<task_name>.md in the workdir. Always report the results in the workdir provided by the leader agent. In this report, you should include a summary, and detailed necessary and related information, and also all the figures/tables you have generated.

Large dataset handling:

If the dataset is very large(relatively to the memory of the computer), or the analysis is always timeout, you should consider creating a subset of the dataset, and then perform the analysis on the subset.

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.

analysis_expert is an agent published in the GitHub repository aristoteleo/PantheonOS (482 stars, last pushed yesterday), licensed BSD-2-Clause. It adds 47 tokens to every session and 1,807 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 2026-08-30.
