What it does

Single Cell Preprocessing With Omicverse is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Walk through omicverse's single-cell preprocessing tutorials to QC PBMC3k data, normalise counts, detect HVGs, and run PCA/embedding pipelines on CPU, CPU–GPU mixed, or GPU stacks.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Research & Science, covering Bioinformatics and Embeddings. It works with Jupyter. The repository describes itself as: The largest open-source medical AI skills library for OpenClaw🦞.

When your agent uses it

  • Tasks that involve Bioinformatics
  • Tasks that involve Embeddings

Example prompts

  • “/single-cell-preprocessing-with-omicverse”

Requirements

  • Python 3

Workflow steps

11 steps, taken from the first numbered list in SKILL.md.

  1. Set up the environment
  2. Prepare input data
  3. Perform quality control (QC)
  4. Store raw counts before transformations
  5. Normalise and select HVGs
  6. Manage .raw and layer recovery
  7. Scale, reduce, and embed
  8. Cluster and annotate
  9. Document outputs
  10. Notebook-specific notes
  11. Troubleshooting tips

What it can do on your machine

Read from SKILL.md and the folder at commit b1f9b6e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Single Cell Preprocessing With Omicverse loads about 2.8k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 922 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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.

Safety

Auto-check passed

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 922 words (~2,841 tokens).

“Follow this skill when a user needs to reproduce the preprocessing workflow from the omicverse notebooks t_preprocess.ipynb, t_preprocess_cpu.ipynb, and t_preprocess_gpu.ipynb. The tutorials operate on the 10x PBMC3k dataset and cover QC filtering, normalisation, highly variable gene (HVG) detection, dimensionality reduction…”
