Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00168 | $0.11505 |
| Opus 5 | $0.00084 | $0.05752 |
| Sonnet 5 | $0.00034 | $0.02301 |
| Haiku 4.5 | $0.00017 | $0.01150 |
Grade A, and why
bio-causal-genomics-transcriptome-wide-association 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 13d 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.
This is a copy
97% identical to bio-causal-genomics-transcriptome-wide-association — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 472 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Version Compatibility
Reference examples tested with: FUSION (head of gusevlab/fusion_twas, scripts dated 2023+), MetaXcan / S-PrediXcan / S-MultiXcan 0.7.5+ (hakyimlab/MetaXcan), PrediXcan model files from PredictDB (GTEx v8 elastic-net + MASHR), UTMOST (head of Joker-Jerome/UTMOST), pyfocus 0.8+ (bogdanlab/focus), MA-FOCUS (head of mancusolab/ma-focus), TIGAR-V2 (head of yanglab-emory/TIGAR), PLINK 1.9 + PLINK 2.0, R 4.3+, Python 3.9-3.11.
Before using code patterns, verify installed versions match. If versions differ:
- R:
Rscript --version; for FUSION scripts inspect--helpflags directly in the source - Python:
pip show pyfocus(MetaXcan is git-cloned, not on PyPI) thenSPrediXcan.py --help,SMulTiXcan.py --help,focus finemap --help - CLI:
plink2 --version; FUSION ships as R scripts not a binary
If a script throws an error about an argument that has moved (e.g. --gwas_file vs --gwas-file) or a model database schema change, introspect the installed script with --help and adapt rather than retrying. PredictDB model file paths change with GTEx version; pin the version explicitly in scripts.
Transcriptome-Wide Association
"Find genes whose predicted tissue expression is associated with my GWAS trait" -> Train SNP -> expression prediction models on a reference eQTL panel, apply the per-gene SNP weights to GWAS summary statistics or genotypes, and produce a gene-level Z-score equivalent to a weighted sum of SNP Z-scores. The output is a gene-by-tissue association, but TWAS is NOT direct evidence of causal mediation: an LD-tagged eQTL signal produces the same statistical association as a truly causal one, and the dominant failure modes are LD-induced false positives at gene-dense loci, tissue mis-specification, and ancestry mismatch between GWAS and prediction weights.

What ships with it
3 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.
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-causal-genomics-transcriptome-wide-association is a skill published in the GitHub repository PKU-YuanGroup/OpenAI4S (407 stars, last pushed yesterday), licensed MIT. It adds 168 tokens to every session and 11,505 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to bio-causal-genomics-transcriptome-wide-association, differing in 12 lines, and is treated as a copy.
