bio-logic

bio-logic is a skill for Claude Code from fmschulz/omics-skills. It costs 36 tokens per session (2,078 once invoked), scanned A, original, MIT.

A framework for checking scientific claims, study methods, bias, and the strength of supporting evidence.

In plain words
What is it for?
Critiquing papers, evaluating study designs and analyses, assessing causal claims, and revising hypotheses during exploratory work.
Why use it?
It helps separate what a study shows from what it merely suggests, while identifying missing tests and alternative explanations.

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-logic 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 23d 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.

Bio-Logic: Scientific Reasoning Evaluation

Use structured frameworks to evaluate scientific claims, methodology, and evidence strength.

Instructions

  1. Identify the task (claim assessment, paper critique, study design review, project interpretation, or hypothesis revision).
  2. For project work, maintain a hypothesis register with at least 5 distinct active hypotheses until the project is no longer exploratory.
  3. After each major intermediate result, reflect on what changed, revise hypothesis status, and identify the next discriminating check.
  4. When findings need context, pair this reasoning with a literature-search skill such as /polars-dovmed, then revise hypotheses against the literature.
  5. Select the study-type profile before applying a checklist. Do not grade a computational benchmark, phylogenetic analysis, or evolutionary inference as if it were an intervention trial.
  6. Structure output using the provided format.

Study-Type Profiles

Profile Main evidence checks Rating language
Intervention allocation, controls, adherence, attrition, estimand, harms GRADE when the review question and evidence synthesis support it
Observational or quasi-experimental identification assumptions, temporality, confounding, negative controls, sensitivity analyses risk-of-bias plus causal-confidence statement
Computational or machine learning data provenance, leakage, splits, baselines, calibration, external validation, reproducibility computational evidence confidence
Evolutionary or comparative genomics orthology, taxon/reference sampling, model fit, support, contamination, topology sensitivity phylogenetic/comparative evidence confidence
Descriptive or exploratory omics sampling, measurement, multiple testing, effect sizes, replication, alternative explanations descriptive confidence; avoid causal labels

Project Hypothesis Loop

Use this loop for omics projects, unexpected results, exploratory analyses, and any request that asks what results mean.

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-logic is a skill published in the GitHub repository fmschulz/omics-skills (11 stars, last pushed 23d ago), licensed MIT. It adds 36 tokens to every session and 2,078 once invoked, about $0.0001 per session on Opus 5.5. 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.
