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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.04704 |
| Opus 5 | $0.00030 | $0.02352 |
| Sonnet 5 | $0.00012 | $0.00941 |
| Haiku 4.5 | $0.00006 | $0.00470 |
Grade A, and why
clinical-research-analysis-framework 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 580 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Statistical Analysis Framework
Overview
This skill provides a consultation-first workflow for statistical and machine learning analyses. Rather than jumping to implementation, it guides users through structured decision-making to ensure:
- Research intent is fully captured before any code runs
- Method selection is informed by trade-offs, not defaults
- Assumptions and limitations are explicitly acknowledged
- Execution is stepwise with checkpoints for user feedback
- All work is reproducible with complete audit trails
When to Use This Skill
- Planning a new analysis on MIMIC, eICU, or similar data
- Choosing between statistical inference vs predictive modeling
- Needing guidance on appropriate methods for a research question
- Executing analyses with reproducibility requirements
- Validating ML models or statistical findings
Guiding Philosophy
This Skill Guides, Not Limits
The methods and checklists in this skill are starting points, not boundaries. Claude's statistical knowledge extends far beyond what is explicitly listed here. When a user's problem calls for a method not covered in the references — whether that's g-computation, Bayesian hierarchical models, causal forests, doubly robust estimation, joint longitudinal-survival models, or something else entirely — Claude should:
- Suggest it with clear explanation of why it fits better
- Explain the intuition so the user understands the approach
- Compare it to simpler alternatives with trade-offs
- Let the user decide based on understanding, not just trust
The Collaboration Model
User describes problem
↓
Claude suggests methods (from full knowledge, not just this skill)
↓
Claude explains: "Here's why this fits your situation..."
↓
User asks questions, pushes back, explores alternatives
↓
Claude refines: "Given that concern, consider instead..."
↓
User makes informed choice
↓
Proceed with understanding, not blind execution

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.

clinical-research-analysis-framework is a skill published in the GitHub repository hannesill/m4 (43 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 4,704 once invoked, about $0.0003 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 2026-08-30.
