Skills for opening and driving agent-controllable visualization components in the Pantheon UI sidebar — interactive viewers the agent can open, control, and read back. Viewers: Vitessce (spatial / single- cell omics), Viv (bioimage / microscopy), volume3d (3D image volumes — MIP/ISO), spatial3d (3D spatial transcriptomics), Mol*, IGV, Gosling, Cytoscape, MSA, RDKit, phylotree, plus agent-generated apps.
General-purpose skills for data analysis infrastructure: workspace file organization, environment management, parallel computing, and performance.
Skills for single-cell and spatial omics data analysis. Best practices, code snippets, and workflows for the scverse ecosystem.
Aesthetic guidelines and output-type recipes for scientific figure production. Supports lightweight default-agent use through SKILL.md + one outputType recipe, with optional venue-specific style guides when requested.
Query the Virtual Embryo knowledge graph (mouse/human developmental biology: genes, anatomy, Theiler/Carnegie stages, gene expression, diseases, papers) and its 3D atlas catalog (anatomical OPT/light-sheet volumes + 3D spatial- transcriptomics datasets), and visualise those datasets in 3D with the volume3d / spatial3d live-view viewers. Public read-only HTTP API at https://kg.virtualembryo.ai — no auth, no key needed for reads. Use when the user asks about mouse/human embryo development, where a gene is expressed, an anatomical structure, a developmental stage, or wants to see/visualise the Virtual Embryo atlas or spatial-transcriptomics data.
Skills for rare disease case support: ontology-first normalization/retrieval and the clinical genetics consult report format contract (structure + theme). Load the relevant skill file when performing the matching task.

Instance segmentation tools for cells and nuclei in microscopy images. Use the tool selection guide below to choose the right method, then load the corresponding skill file for detailed usage.
| Goal | Recommended Tool | Speed | Tested |
|---|---|---|---|
| Best overall accuracy | Cellpose-SAM (v4.x) | Moderate (~310s/1024px CPU) | ✅ 955 cells |
| Fastest inference | InstanSeg | Fast (~7s/1024px CPU) | ✅ 586 cells |
| Low quality / noisy images | Cellpose 3 (image restoration) | Moderate | ✅ |
| Round nuclei only | StarDist | Fastest (~0.5s) | ✅ 150 cells |
| Whole-cell (nucleus + membrane) | Mesmer / DeepCell | Moderate | ⚠️ install issues |
| Interactive annotation / 3D / tracking | micro-sam | Slow | ⚠️ Python 3.10+ |
| Fully automatic, no prompts | CellSAM | Moderate | ⚠️ Python 3.10+ |
[!TIP] Start with Cellpose (default in v4.x) for most tasks. It has the best generalization. Switch to InstanSeg if speed matters or you need simultaneous nuclei + cell masks.
[!WARNING] Environment isolation is important. These tools have conflicting dependencies. Cellpose/InstanSeg use PyTorch; StarDist/Mesmer use TensorFlow; SAM-based tools need Python 3.10+. Create separate virtual environments for each tool family:
venv-cellpose: Cellpose + InstanSeg (both PyTorch)venv-stardist: StarDist (TensorFlow,numpy<2)venv-deepcell: Mesmer/DeepCell (TensorFlow, strict numpy version)venv-sam: micro-sam / CellSAM (Python 3.10+)
General-purpose cell and nucleus segmentation using Cellpose v4.x (includes Cellpose-SAM with ViT-L backbone). Image restoration, fine-tuning, and 3D segmentation.
Skill file: cellpose.md
When to use: Default choice for most segmentation tasks.
Fast cell and nucleus segmentation with dual output (nuclei + cells simultaneously). Supports multiplexed images via ChannelNet.
Skill file: instanseg.md
When to use: Speed-critical workflows, multiplexed images, QuPath integration.
Nuclear segmentation using star-convex polygon prediction. Extremely fast but assumes round/convex nuclei.
Skill file: stardist.md
When to use: Round nuclei in fluorescence images where speed matters.
Whole-cell segmentation using both nuclear and membrane markers. TissueNet-trained PanopticNet architecture.
Skill file: mesmer.md
When to use: Tissue images with both nuclear and membrane/cytoplasm markers.
Cell segmentation using SAM adaptations: CellSAM (automatic), micro-sam (interactive + 3D), SAMCell (label-free).
Skill file: sam_based.md
When to use: Interactive annotation, 3D/tracking, or label-free brightfield.
