dismech: Skill for Claude Code

.claude/skills/microbiome-curation/SKILL.md

microbiome-curation is a skill for Claude Code from monarch-initiative/dismech. It costs 85 tokens per session (2,831 once invoked), scanned A, original, BSD-3-Clause.

A guide for adding microbiome disease mechanisms to a knowledge base. The microbiome is the community of microorganisms living in and on the body, and pathophysiology describes how disease develops and affects the body.

In plain words
What is it for?
Curating links between microbial diversity, metabolites, host effects, and diseases such as inflammatory bowel disease and C. difficile infection.
Why use it?
It helps turn broad claims about microbial imbalance into smaller, linked cause-and-effect entries supported by ecological concepts and research literature.

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

microbiome-curation 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 1mo 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.

Microbiome Curation Skill

Overview

Curate microbiome-related pathophysiology entries with ecological depth beyond simple taxa +/- lists. Focus on:

  • Ecological concepts (diversity, stability, keystone taxa)
  • Causal chains from dysbiosis to clinical manifestations
  • Metabolic consequences (SCFA, bile acids)
  • Integration with BugSigDB and primary literature

When to Use

  • Adding microbiome dysbiosis entries to disorders
  • Curating pathophysiology for IBD, C. diff, obesity, metabolic diseases
  • Decomposing "microbiome dysbiosis" into causal graph nodes
  • Adding ecological concepts (Anna Karenina, colonization resistance)
  • Linking microbial metabolites to host pathophysiology

Key Principle: Graph Structure Over Monolithic Entries

DO NOT create single entries bundling all microbiome effects:

# BAD - monolithic entry
- name: Microbiome Dysbiosis
  description: >
    Reduced diversity with depletion of Firmicutes and expansion of pathobionts,
    leading to decreased SCFA and barrier dysfunction.

DO decompose into atomic nodes with downstream edges:

# GOOD - causal graph
- name: Loss of Microbial Diversity
  downstream:
  - target: Loss of Keystone SCFA Producers
  - target: Increased Microbial Community Instability

- name: Loss of Keystone SCFA Producers
  downstream:
  - target: Decreased Butyrate Production

- name: Decreased Butyrate Production
  downstream:
  - target: Impaired Colonocyte Energy Metabolism

- name: Impaired Colonocyte Energy Metabolism
  downstream:
  - target: Epithelial Barrier Dysfunction

This enables:

  1. Shared nodes across disorders
  2. Explicit feedback loops
  3. Targeted therapeutic entry points
  4. Evidence on specific causal steps

Ecological Dimensions of Dysbiosis

Beyond Taxa +/-

BugSigDB captures increased/decreased taxa, but ecology is richer:

Dimension What it captures Example
Taxonomic Which species +/- Faecalibacterium, E. coli
α-Diversity Richness/evenness Shannon index
β-Diversity Inter-individual variability Anna Karenina effect
Functional Pathway capacity Butyrate synthesis genes
Metabolic Actual output Fecal SCFA concentrations
Network Community structure Keystone taxa, modularity
Stability Resilience Alternative stable states

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.

microbiome-curation is a skill published in the GitHub repository monarch-initiative/dismech (69 stars, last pushed today), licensed BSD-3-Clause. It adds 85 tokens to every session and 2,831 once invoked, about $0.0003 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 2026-09-15.
