spatial-register

spatial-register is a skill for Claude Code, Codex from TianGzlab/OmicsClaw. It costs 62 tokens per session (1,796 once invoked), scanned A, original, Apache-2.0.

A tool for aligning multiple spatial transcriptomics tissue slices into one shared coordinate system. This makes positions from different slices comparable.

In plain words
What is it for?
Use it with multi-slice Visium or Xenium AnnData data, optionally using histology images, through PASTE or STalign.
Why use it?
It helps combine or compare slices when each one was measured in its own physical coordinate frame.

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-register 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 yesterday.

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

When to use

The user has a multi-slice spatial AnnData (slices stacked into one object with a --slice-key column) and wants the slices registered into a shared coordinate frame so a downstream analysis can use the common axes. Two methods:

  • paste (default) — PASTE optimal-transport alignment based on gene expression similarity + spatial proximity (--paste-alpha, --paste-dissimilarity). Requires paste-bio + pot (+ optional torch for GPU).
  • stalign — STalign image-aware diffeomorphic registration; best when histology images are available (--stalign-niter, --stalign-image-size, --stalign-a). Requires STalign + torch.

For expression-space batch correction across slices use spatial-integrate. For aligning a single slice to a reference atlas use the same skill with that atlas as the reference slice.

Inputs & Outputs

Inputs

  • Modalities: visium, xenium
  • File types: .h5ad
  • Requires a preprocessed AnnData (X normalised, PCA/neighbours present)

Outputs

  • tables/registration_disparities.csv
  • tables/registration_metrics.csv
  • tables/registration_points.csv
  • tables/registration_run_summary.csv
  • tables/registration_shift_by_slice.csv
  • tables/registration_summary.csv
  • figures/registration_disparities.png
  • figures/registration_shift_by_slice.png
  • figures/registration_shift_distribution.png
  • figures/registration_shift_map.png
  • figures/slices_after.png
  • figures/slices_before.png
  • processed.h5ad
  • report.md
  • result.json
  • Processed AnnData (saves_h5ad) — adds obsm: spatial_aligned, spatial, X_spatial

Flow

  1. Load AnnData (--input) or build a multi-slice demo via the bundled spatial-preprocess runner (chains across slices).
  2. parser.error validates numeric flag ranges (--paste-alpha ∈ [0, 1]; --stalign-niter/-image-size/-a > 0).
  3. Resolve --slice-key (auto-pick from slice / sample / library_id if unset); raise if < 2 slices.
  4. Pick a reference slice (largest by default) and align all others to it.
  5. For PASTE: compute pairwise transport plans using --paste-alpha (gene-vs-spatial weight); apply translations.
  6. For STalign: run iterative image-aware diffeomorphism with --stalign-niter iterations.
  7. Save processed.h5ad (registered coords in obsm["spatial_aligned"]; original obsm["spatial"] preserved unchanged), tables, figures, report.md, result.json.

What ships with it

8 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-register is a skill published in the GitHub repository TianGzlab/OmicsClaw (160 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 62 tokens to every session and 1,796 once invoked, about $0.0003 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 2026-09-03.
