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 | $0.00107 | $0.04231 |
| Opus 5 | $0.00053 | $0.02116 |
| Sonnet 5 | $0.00021 | $0.00846 |
| Haiku 4.5 | $0.00011 | $0.00423 |
Grade A, and why
bio-data-visualization-forest-funnel-plots 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 7d 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
92% identical to bio-data-visualization-forest-funnel-plots — 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 — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Version Compatibility
Reference examples tested with: metafor 4.4+, forestplot 3.1+, ggforestplot 0.1+ (subgroup forests), ggforest from survminer 0.4.9+, MendelianRandomization 0.10+.
Before using code patterns, verify installed versions match. If versions differ:
- R:
packageVersion('<pkg>')then?function_name
If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.
Forest and Funnel Plots
"Summarize effects across studies / subgroups" -> Render each effect estimate (HR, OR, RR, β) as a square (size = inverse variance / weight), horizontal bar (95% CI), and label, with an optional summary diamond at the bottom from a meta-analysis pool (fixed-effect or random-effects). The funnel plot diagnoses publication bias by plotting effect size vs precision; asymmetry indicates missing small-study-with-null-result publications (Egger 1997).
- R:
metafor::forest,metafor::funnel,forestplot::forestplot,survminer::ggforest(Cox HR forests),MendelianRandomization::mr_forest
The Single Most Important Modern Insight -- Heterogeneity Is the First Question
A pooled effect estimate is meaningless if the underlying studies are heterogeneous. The Higgins I² statistic (Higgins-Thompson 2002 Stat Med 21:1539) quantifies between-study variance; the conventional 25/50/75% interpretation tiers come from the Cochrane Handbook §10.10.2 (Higgins et al editors), NOT the original Higgins-Thompson paper which cautioned against rigid cutoffs. A meta-analysis with I² > 75% and a pooled effect must explain the heterogeneity (subgroup analysis, meta-regression) — pooling without explanation is statistically defensible but biologically unhelpful.
A forest plot's bottom must report: pooled estimate + 95% CI + I² + τ² (between-study variance) + Q-test p-value. Without these, the plot is a list of effects, not a meta-analysis.

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.
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-data-visualization-forest-funnel-plots is a skill published in the GitHub repository PKU-YuanGroup/OpenAI4S (403 stars, last pushed today), licensed MIT. It adds 107 tokens to every session and 4,231 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to bio-data-visualization-forest-funnel-plots, differing in 12 lines, and is treated as a copy.
