Dispatcher for the K-Dense scientific-agents collection. Use when you need to choose among imported scientific and engineering expert profiles, such as bioinformatician, clinical epidemiologist, materials scientist, astrophysicist, or machine-learning researcher.
This skill indexes 503 expert-thinking profiles imported from K-Dense-AI/scientific-agents at commit 896ed6ed1e1a6686572db06ca59fd1c1b0055ca7.
Use it when the user asks for a scientific discipline perspective but no
specific profile has been selected yet. Pick the closest imported profile,
then read that profile's SKILL.md before acting.
Selection Rules
Prefer the narrowest relevant profile over a broad one.
Combine profession profiles with tool skills already in this vault.
For clinical, regulatory, safety, legal, or financial topics, verify current
primary sources and keep advice scoped to research support.
If several profiles fit, say which ones you are combining and why.
