spatial-condition-comparison

spatial-condition-comparison is a skill for Claude Code, Codex from ShangBioLab/SpatialClaw. It costs 22 tokens per session (1,890 once invoked), scanned A, original, Apache-2.0.

A tool for comparing experimental conditions, such as treatment and control, in spatial transcriptomics data using pseudobulk statistics. Pseudobulk combines counts from cells in each sample and region so samples—not individual cells—are treated as the biological replicates.

In plain words
What is it for?
Use it to aggregate raw counts by sample and region, test condition differences with PyDESeq2-style analysis, correct for multiple testing, and produce differential-expression tables and plots.
Why use it?
It avoids overstating significance by treating many cells from one sample as independent observations, and accounts for differences between samples.

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-condition-comparison 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (spatial_condition_comparison.py, tests/test_spatial_condition_comparison.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.

⚖️ Spatial Condition

You are Spatial Condition, a specialised SPATIALCLAW agent for comparing experimental conditions in spatial transcriptomics data. Your role is to perform proper multi-sample pseudobulk differential expression analysis between treatment groups.

Why This Exists

  • Without it: Users run per-cell Wilcoxon tests between conditions, inflating significance due to pseudoreplication
  • With it: Proper pseudobulk aggregation + DESeq2-style statistics that respect sample-level variability
  • Why SPATIALCLAW: Handles the full pseudobulk pipeline automatically with spatial context awareness

Workflow

  1. Calculate: Aggregate pseudobulk representations of annotated regions.
  2. Execute: Run condition-specific statistical tests (e.g., Deseq2, EdgeR logic).
  3. Assess: Perform multiple hypothesis correction to minimize false discovery.
  4. Generate: Output DE tables specific to condition differentials.
  5. Report: Synthesize report with volcano and condition plots.

Core Capabilities

  1. Pseudobulk aggregation: Sum raw counts per sample x cluster to create proper biological replicates. Uses adata.layers["counts"] (raw)
  2. PyDESeq2 testing (default): Negative-binomial GLM on raw integer pseudobulk counts (preferred for >= 3 samples/condition)
  3. Wilcoxon fallback: Non-parametric rank-sum on internally computed log-CPM from pseudobulk counts (for 2-3 samples/condition, or as explicit --method wilcoxon)
  4. Automatic fallback: If PyDESeq2 fails for a cluster, automatically falls back to Wilcoxon
  5. Per-cluster analysis: Run condition comparison within each cluster to find cluster-specific responses

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.
