bio-structure-annotation

bio-structure-annotation is a skill for Claude Code from fmschulz/omics-skills. It costs 40 tokens per session (764 once invoked), scanned A, original, MIT.

A workflow for predicting protein shapes and using those shapes to infer protein functions, domains, interactions, or binding behavior. It can screen sequences and search predicted or experimentally measured structures.

In plain words
What is it for?
Use it to screen candidate proteins, predict structures, compare them with known structures, identify remote similarities, and investigate domains or molecular complexes.
Why use it?
It helps when the protein sequence alone does not provide enough evidence to understand how the protein works.

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

bio-structure-annotation 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/run_structure_annotation.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Bio Structure Annotation

Structure prediction and structure-based annotation.

Instructions

Tool guides and versions: docs/README.md.

  1. Run a fast embedding screen with TM-Vec to triage candidate proteins by remote homology before incurring structure-prediction cost.
  2. Predict structures on a GPU node. AlphaFold3 is intentionally not part of this stack (non-commercial license, large VRAM footprint, no clear quality gap for the workflows in this repo). Use:
    • Boltz-2 (MIT license; CUDA; NVIDIA cuEquivariance kernels) as the default predictor — joint structure-and-affinity, ~1000× faster than FEP for binding-affinity estimation, comparable accuracy to AF3 on benchmarked complexes.
    • ColabFold v1.5.5+ with an MMseqs2-GPU MSA backend when a wider MSA than Boltz-2 builds is required (≈31.8× faster MSA generation versus the standard AF2 pipeline; Nature Protocols 2025, DOI: 10.1038/s41596-024-01060-5).
    • ESMFold for fast monomer pre-screening only (15–20 GB VRAM; lower accuracy than Boltz-2).
  3. Search predicted or experimental structures with Foldseek v9+. Use --gpu 1 on CUDA Turing or newer for the ProstT5-backed search (4–27× speedup). Consider Foldseek-Multimer when complex-vs-complex search is needed.
  4. Annotate hits and route high-value unknowns back to /bio-annotation for sequence-side context, or to comparative analyses via /bio-protein-clustering-pangenome.
  5. Build and validate commands with scripts/run_structure_annotation.py. Public MSA services receive biological sequences; --use-msa-server is rejected unless the user explicitly approved upload with --approve-public-msa-upload.

What ships with it

8 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.

bio-structure-annotation is a skill published in the GitHub repository fmschulz/omics-skills (7 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 764 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.
