sc-standardize-inputLoad when an external single-cell h5ad/h5/loom/mtx needs to be canonicalised onto the OmicsClaw AnnData contract before downstream scRNA skills run.
Sc Standardize Input is an agent skill from TianGzlab/OmicsClaw. Load when an external single-cell h5ad/h5/loom/mtx needs to be canonicalised onto the OmicsClaw AnnData contract before downstream scRNA skills run. Skip when data already came from sc-count (already canonical); bulk RNA-seq (use bulkrna-qc); spatial (use spatial-preprocess).
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `_api.py`, `examples/example_step.py` and `references/methodology.md`).
It sits in Research & Science, covering Bioinformatics. It works with AnnData. The repository describes itself as: Conversational & memory-enabled AI research partner for multi-omics analysis. CLI + Desktop App (installers in Releases). From biological idea to full research paper. The licence is Apache-2.0.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 90a3bec. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Sc Standardize Input loads about 1.4k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 538 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

standardize(adata, *, species: str='auto')Return a canonical copy with count-like X, layers['counts'] and raw.
Select counts from layers['counts'], aligned raw or X, in that order; harmonize feature names and record the matrix and input contracts.
:param adata: AnnData with at least one count-like expression matrix. :param species: 'auto' uses infer_species; 'human' or 'mouse' overrides it. :returns: A new AnnData. run_info reports the selected matrix and warnings. :raises ValueError: The species is invalid or no count-like matrix is present.
infer_species(adata) -> strInfer human or mouse from feature names, defaulting to human.
:param adata: AnnData whose feature names or gene-symbol metadata are examined. :returns: The species hint used by standardize(species="auto").
run_info(adata, *, keep: bool=True) -> dictRead standardization diagnostics stored as JSON in adata.uns.
:param adata: The AnnData returned by standardize. :param keep: False removes these diagnostics after reading; default True. :returns: A dictionary, or an empty dictionary before standardize runs.
<!-- api:end -->
species="auto" uses the existing gene-name heuristic; use human or
mouse when the organism is known. infer_species exposes that heuristic.
Counts are selected from layers["counts"], aligned raw, then X.
run_info reports the chosen source and any warnings. This method has no
random state or optional backend.

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add TianGzlab/OmicsClaw --skill sc-standardize-input -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sc-standardize-input, .gemini/skills/sc-standardize-input, .github/skills/sc-standardize-input and .opencode/skills/sc-standardize-input in your project.
Going by SKILL.md and its folder, Sc Standardize Input needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Sc Standardize Input is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.1k tokens, read only when the agent opens those files.
