rh-skills: Skill for Claude Code

.agents/skills/reasonhub-semantic-snomed/SKILL.md

reasonhub-snomed-semantic is a skill for Claude Code, Codex from reason-healthcare/rh-skills. It costs 118 tokens per session (6,391 once invoked), scanned A, original, no licence file.

A clinical knowledge tool that uses SNOMED CT relationships to answer questions about medical concepts. SNOMED CT is a system for representing clinical findings, disorders, procedures, and their connections.

In plain words
What is it for?
Use it to find concepts by attributes such as body site or cause, navigate broader and narrower concepts, and build filtered groups of related concepts.
Why use it?
It helps explore medical concepts by their meaning and relationships instead of relying only on exact code names.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is reason-healthcare/rh-skills's own configuration. It tells Claude Code and Codex how to work on rh-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rh-skills configures →

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

reasonhub-snomed-semantic scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
