spatial-xenium

Xenium platform branch of the spatial transcriptomics workflow — load and validate the platform's cell-level matrix for downstream analysis. Use when the user's data is 10x Xenium output (cell_feature_matrix.h5, cell-level h5ad, or transcripts.csv + segmentation). Produces a cell-level h5ad, then stops for review.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by QING1105 on GitHub. Read the source before you install it.

Installation

Install the Spatial Xenium AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/QING1105/ezST/tree/master/plugins/spatial-transcriptomics/skills/spatial-xenium
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/QING1105/ezST.git /tmp/ezST
mkdir -p .claude/skills
cp -r /tmp/ezST/plugins/spatial-transcriptomics/skills/spatial-xenium .claude/skills/spatial-xenium

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Spatial Xenium in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Spatial Xenium on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Spatial Xenium is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Xenium Branch — Cell-Level Loading & Validation

Goal

Load Xenium data as a cell-level matrix. Xenium is an imaging-based in situ platform that outputs cell barcodes with platform-provided segmentation — no re-segmentation and no deconvolution needed.

Prerequisites

Xenium output, one of:
- cell_feature_matrix.h5 (standard Xenium output; cells × genes)
- cell-level h5ad with obsm['spatial']
- transcripts.csv (transcript-level) + segmentation boundaries
Python: scanpy

Steps

Load cell matrix
- sc.read_10x_h5(cell_feature_matrix.h5) — cells × genes, sparse.
- Attach coordinates: Xenium outputs have pxl_col_in_fullres / pxl_row_in_fullres or obsm['spatial'].
Validate platform segmentation
- Confirm cell boundaries exist (nucleus or cell segmentation from Xenium pipeline).
- Do NOT re-segment unless the user explicitly asks.
QC & sanity check
- Report: number of cells, median genes/cell, median counts/cell.
- Flag: very low counts (possible empty cells), very high counts (possible doublets), abnormal spatial distribution.

Outputs

results/01_loading/<sample>_cells.h5ad — cell-level AnnData
results/01_loading/QC_plots.png — QC violin plots

Biological Interpretation

Report total cells and QC stats.
Note tissue type and expected cell composition.
Flag any platform QC warnings.

Stop for Review

Present interpretation using the template from the parent spatial-transcriptomics skill. Wait for 通过 / 调整 / 跳过 before proceeding to shared downstream.

Notes

Xenium segmentation comes with the platform — treat as ground truth unless the user asks otherwise.
Deconvolution is NOT needed for Xenium — cells are already resolved.

Frequently asked questions

What does the Spatial Xenium AI skill do?

Why use Spatial Xenium on TypingMind?

Because you install it once and use it with any model. Spatial Xenium is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Spatial Xenium in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/QING1105/ezST/tree/master/plugins/spatial-transcriptomics/skills/spatial-xenium. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Spatial Xenium?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Spatial Xenium?

As many as you like. As long as a model supports skills, you can use Spatial Xenium with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Spatial Xenium AI skill free?

Yes. It is published on GitHub by QING1105 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
