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 | $0.00034 | $0.02044 |
| Opus 5 | $0.00017 | $0.01022 |
| Sonnet 5 | $0.00007 | $0.00409 |
| Haiku 4.5 | $0.00003 | $0.00204 |
Grade A, and why
nma-methodology 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 8d 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.

Network Meta-Analysis Methodology
Comprehensive methodological guidance for conducting rigorous network meta-analysis following NICE DSU and PRISMA-NMA guidelines.
When to Use This Skill
- Planning a network meta-analysis
- Assessing transitivity and consistency
- Interpreting treatment rankings
- Choosing between frequentist and Bayesian NMA
- Designing NMA sensitivity analyses
- Reviewing NMA code or results
Fundamental Assumptions
1. Transitivity Assumption
Definition: If we can estimate A vs B directly and B vs C directly, we can estimate A vs C indirectly, provided the studies are sufficiently similar.
Requirements:
- Studies comparing different treatments should be similar enough to have been included in the same RCT
- Effect modifiers should be balanced across comparisons
- No important differences in study-level characteristics
Assessment:
For each comparison in network, check:
├── Population similarity
│ - Age, sex, disease severity
│ - Biomarker status, prior treatments
├── Outcome definitions
│ - Same definition of response/event
│ - Same time point of assessment
├── Treatment definitions
│ - Dose, duration, route
│ - Concomitant medications
└── Study design
- Randomization, blinding
- Follow-up duration
Presenting Transitivity Assessment:
- Create table of study characteristics by comparison
- Highlight any systematic differences
- Use forest plots stratified by comparison
2. Consistency Assumption
Definition: Direct and indirect evidence for the same comparison should agree (within random variability).
Relation to Transitivity:
- Transitivity is untestable (conceptual)
- Consistency is testable (statistical)
- Consistency violations suggest transitivity violations
Consistency Assessment
Global Consistency Tests
Design-by-Treatment Interaction
# netmeta
decomp.design(nma_result)
# Tests overall consistency across network
# Q statistic partitioned into within-design and between-design
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.

nma-methodology is a skill published in the GitHub repository choxos/BiostatAgent (11 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 2,044 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 2026-08-30.
