open-genome-agent: Skill for Claude Code

.agents/skills/annotate-variants/SKILL.md

annotate-variants is a skill for Claude Code, Codex from 45ck/open-genome-agent. It costs 32 tokens per session (295 once invoked), scanned A, original, MIT.

A genetics-analysis step that adds information about what changes in DNA may do to genes and transcripts. It uses tools such as VEP, which predicts variant consequences, and records the exact tools and commands used.

In plain words
What is it for?
Use it after DNA variants have been normalized and before ranking them. It produces structured annotation data, tool-version records, and command logs.
Why use it?
It makes later variant ranking traceable and repeatable instead of relying on undocumented tool runs. It also keeps incomplete results, mismatched reference builds, and other failures visible.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is 45ck/open-genome-agent's own configuration. It tells Claude Code and Codex how to work on open-genome-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything open-genome-agent configures →

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

annotate-variants 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 6d 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.

What it actually says

Annotate variants

Annotate variants with deterministic tools such as VEP and preserve exact tool versions and command provenance. Use after normalization and before prioritization.

When to use

  • gene/transcript consequences are needed
  • you need a structured annotation file for later ranking

Do not use when

  • you only need simple file QC

Expected outputs

  • annotations.tsv
  • tool_versions.json
  • commands.jsonl

Goal

Produce a structured annotation layer that downstream agents can rank and report.

Procedure

  1. Confirm build and normalization state first.
  2. Run the selected annotation tool with explicit version capture.
  3. Preserve raw command lines and output paths in commands.jsonl.
  4. Emit a stable tabular or JSON annotation artifact.
  5. Keep tool failures visible and non-silent.

Guardrails

  • Annotation is not interpretation.
  • Do not collapse multiple transcripts into a single unqualified claim.
  • Record exact tool and cache versions when available.

Escalate when

  • required annotation caches are missing
  • reference build does not match tool expectations
  • command output suggests truncation or partial failure

References

See references/README.md for durable notes and scripts/ for deterministic helpers.

Files

What ships with it

2 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.

annotate-variants is a skill published in the GitHub repository 45ck/open-genome-agent (4 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 295 once invoked, about $0.0002 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 2026-08-31.
