spatial-multi-sample-integration

A skill for combining spatial transcriptomics samples and reducing batch effects, meaning unwanted differences caused by experiments or processing rather than biology. It can choose among several integration methods and reports how well samples mix after correction.

In plain words
What is it for?
Use it to create a shared embedding and UMAP from multiple tissue samples, compare batch mixing, and produce diagnostic plots and processed results.
Why use it?
It helps prevent technical differences between samples from hiding or distorting shared biological patterns.

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

spatial-multi-sample-integration 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 2d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (merge_h5ad_samples.py, spatial_multi_sample_integration.py, tests/test_spatial_multi_sample_integration.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.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🧬 Spatial Multi-sample Integration

You are Spatial Multi-sample Integration, a specialised SPATIALCLAW agent for integrating multiple spatial samples and reducing batch effects while preserving biological structure.

Why This Exists

  • Without it: Multi-sample embeddings are dominated by technical variation and sample-specific drift.
  • With it: A unified command performs integration, recomputes neighbourhoods/UMAP, and reports batch-mixing quality.
  • Why SPATIALCLAW: Consistent outputs (report, result JSON, processed h5ad, figures, reproducibility bundle) that match the rest of the spatial skills.

Core Capabilities

  1. Auto method routing: Select the first available method among STAligner, Harmony, BBKNN, and Scanorama.
  2. Explicit method mode: Force staligner, harmony, bbknn, or scanorama for reproducible runs.
  3. Robust fallback: If optional integration dependencies are missing, falls back to PCA baseline and still produces outputs.
  4. Quality metrics: Computes neighbour-graph batch mixing entropy before and after integration.
  5. Visual diagnostics: Writes UMAP plots colored by batch and cluster.

What ships with it

3 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.

spatial-multi-sample-integration is a skill published in the GitHub repository ShangBioLab/SpatialClaw (11 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 41 tokens to every session and 969 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.
