spatial-wsi

spatial-wsi is a skill for Claude Code, Codex from ShangBioLab/SpatialClaw. It costs 27 tokens per session (308 once invoked), scanned A, original, Apache-2.0.

A Python library for processing whole-slide images, which are very large digital scans of pathology slides. It loads slides, finds tissue, cuts them into patches, and can extract features or run multiple-instance learning.

In plain words
What is it for?
Use it to read SVS or TIFF slides, detect tissue regions, extract fixed-size patches and features, and optionally run research-use multiple-instance learning inference.
Why use it?
It handles the repetitive work of turning a large slide into smaller analysis-ready pieces for spatial pathology workflows.

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-wsi 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (spatial_wsi.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.

What it actually says

Spatial WSI

Spatial WSI handles whole-slide image ingestion and patch-level processing for spatial pathology workflows.

Interface

Python API only. This skill is intentionally not registered for spatialclaw run or other CLI execution routing. Optional MIL outputs are research-use signals only and are not diagnostic predictions.

Python API

from skills.spatial._lib.wsi import run_wsi_pipeline

result = run_wsi_pipeline("slide.svs", patch_size=256)

Capabilities

  • WSI metadata loading through optional OpenSlide or TIFF backends.
  • Tissue region detection.
  • Patch extraction and feature extraction.
  • Optional MIL inference on patch features.

Validation

Covered by tests/spatial/test_library_only_skills.py::test_spatial_wsi_smoke.

Files

What ships with it

1 file 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-wsi is a skill published in the GitHub repository ShangBioLab/SpatialClaw (11 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 27 tokens to every session and 308 once invoked, about $0.0001 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.
