cognitive-scientist

cognitive-scientist is a plugin for Claude Code from K-Dense-AI/scientific-agents. Its manifest loads nothing; the 1 agent it bundles cost 79 tokens per session together, scanned A, original, MIT.

A cognitive-science expert for studying how people perceive, remember, decide, and solve problems through experiments and computational models.

In plain words
What is it for?
Use it to design behavioural experiments, analyse response speed and accuracy, evaluate decision models, and plan studies in tools such as PsychoPy, a program for running psychology experiments.
Why use it?
It helps separate hidden mental processes from the observable results of a task, such as reaction time and accuracy, and helps detect misleading effects or poorly designed comparisons.

Security

Grade A, and why

cognitive-scientist 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 3d 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.

What it installs

The manifest is a name and a version. 1 agent travel with it, and installing the plugin installs all of them — 79 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

cognitive-scientist is a plugin published in the GitHub repository K-Dense-AI/scientific-agents (168 stars, last pushed 19d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-09-03.
