What it does

Clinical Variant Prioritizer is an agent skill from ClawBio/ClawBio. Screen a genotype set (array or WGS-derived) against OMIM-morbid, ACMG-SF and Hereditary-Cancer gene panels and prioritise carried variants by ClinVar significance, gnomAD frequency, inheritance model and zygosity, following the pathogenicity-screening method of Corpas et al. 2021 (Whole Genome Interpretation for a Family of Five).

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `api.py`, `prioritize.py` and `tests/test_api.py`).

It sits in Research & Science, covering Bioinformatics. The repository describes itself as: 🦖 ClawBio - The first bioinformatics-native AI agent skill library. Local-first. Reproducible. Open. Free. The licence is MIT.

When your agent uses it

  • Tasks that involve Bioinformatics

Example prompts

  • “/clinical-variant-prioritizer”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit dece754. 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

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • 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

Clinical Variant Prioritizer loads about 962 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 326 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~962

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.

clinical-variant-prioritizer

Turn a genotype set into a prioritised list of clinically relevant variants, the way a clinical genome analyst would: screen catalogued disease-gene panels, then rank what is carried by how much it matters, not by how loud the raw ClinVar label is.

This skill implements the pathogenicity-screening stage of Whole Genome Interpretation for a Family of Five (Corpas et al., Front Genet 2021): variants are filtered through OMIM-morbid, ACMG-SF and Hereditary-Cancer panels, intersected with ClinVar significance and gnomAD population frequency, and classified by inheritance model and zygosity.

Why it is not a raw ClinVar lookup

A raw lookup reports a label. This skill reports actionability. The same "pathogenic" allele means very different things depending on context:

ContextCategory
Dominant / risk gene, allele carriedactionable
Recessive gene, homozygousaffected
Recessive gene, heterozygouscarrier (reproductive-risk only)
Uncertain / conflicting ClinVaruncertain (flagged, not acted on)
Benign allele carriedbenign
Variant not carriedreference

A heterozygous carrier of a common, recessive, benign-spectrum allele is not an actionable finding, even when ClinVar shows "pathogenic" submissions. Saying so plainly is the point.

Interface

python
from api import run

result = run(
    {"rs28941785": "CT", "rs1800562": "GG"},   # rsid -> genotype
    options={"panel_path": "..."},              # optional custom panel
)

run() returns:

  • summary: panel_size, loci_tested, loci_carried, reference, not_tested, and per-category counts (actionable, affected, carriers, uncertain, benign).
  • findings: ranked list (highest priority first); each carries gene, HGVS, consequence, genotype, zygosity, ClinVar significance + review status, gnomAD frequency, condition, inheritance, panel membership, category and a plain-language rationale.
  • headline, method, disclaimer.

Panel

data/clinical_panel.json is a curated set of catalogued clinical loci, each shipping its ClinVar significance, ClinVar review status, gnomAD frequency, consequence, condition and inheritance model, so the screen is deterministic and offline-reproducible (no per-call ClinVar/gnomAD/VEP network round-trips). Extend it by adding entries; keys may be rsids or stable variant ids for WGS-only variants not present on arrays.

Limitations

Array-based input covers only catalogued loci and misses most rare variants; a clean screen is not a clean genome. Heterozygous calls do not establish phase. Confirm any finding with an accredited clinical assay. Research and educational use only; not a clinical diagnosis.
