dismech: Skill for Claude Code

.claude/skills/noncoding-variant-impact/SKILL.md

noncoding-variant-impact is a skill for Claude Code from monarch-initiative/dismech. It costs 45 tokens per session (2,113 once invoked), scanned A, original, BSD-3-Clause.

A research skill for recording how noncoding genetic variants may affect disease mechanisms. It keeps physical DNA changes, affected regions, gene regulation, expression changes, and confidence as separate claims.

In plain words
What is it for?
Use it to curate or review regulatory single-nucleotide variants and structural variants, including possible effects on splicing, RNA stability, translation, and noncoding RNA.
Why use it?
It prevents a variant's location or overlap with a gene from being treated as proof of a regulatory effect. It also helps preserve the evidence behind uncertain biological conclusions.

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

noncoding-variant-impact 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 1mo ago.

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.

Curating noncoding variant impact

Use the existing fields in the schema. Keep classifications small and optional; preserve evidence-specific detail in descriptions. A noncoding location alone does not establish a regulatory mechanism. Splicing, RNA stability, translation, and noncoding-RNA defects may require different causal steps. An SV can also overlap coding genes while acting primarily through regulation.

Keep the claims separate

Claim Where to record it
Physical alteration Variant.variant_type; initiating node's genetic_context.variant_type
Sequence features overlapped genomic_contexts on either of those objects
Named affected region and its position affected_regions on Variant, GeneticContext, or a regional Genetic record
Gene whose expression is affected or proposed to be affected Variant.regulatory_target_gene; gene annotation on the downstream expression node
Element and direct molecular effect functional_effects[].regulatory_element_type, regulatory_mechanism, and description
Expression pattern regulatory_category on Variant, FunctionalEffect, or Pathophysiology, when supported
Quantitative process change Biological-process descriptor modifier: INCREASED or DECREASED
Downstream consequences Separate, evidence-backed pathophysiology nodes and causal edges

variant_type and genomic_contexts use human-readable static enum values, such as deletion, single nucleotide variant, intron, or "5' UTR". The Sequence Ontology mappings live in the schema; do not add ID/label pairs to these fields. Gene and process annotations still use their normal descriptors.

Contexts can overlap and depend on the transcript. Identify the relevant genes/transcripts in description; an intronic host gene may differ from the regulatory target. Prefer the appropriate UTR context when the overlap is known to be untranslated sequence of a protein-coding transcript, including a wholly untranslated exon such as APC exon 1B. Use noncoding exon for an entire exon without codons when no more specific UTR context applies. Omit unknown contexts. Only put contexts shared by the represented alleles on a shared initiating node. These classifications neither identify an enhancer nor encode genomic coordinates.

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.

noncoding-variant-impact is a skill published in the GitHub repository monarch-initiative/dismech (69 stars, last pushed today), licensed BSD-3-Clause. It adds 45 tokens to every session and 2,113 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-23.
