carbon-cycle-scientist

carbon-cycle-scientist is a plugin for Claude Code from K-Dense-AI/scientific-agents. Its manifest loads nothing; the 1 agent it bundles cost 114 tokens per session together, scanned A, original, MIT.

An expert profile for tracking carbon as it moves between the atmosphere, land, oceans, and other reservoirs over different timescales. It works with measurements, carbon budgets, atmospheric models, and chemical signatures in carbon isotopes.

In plain words
What is it for?
It is for building and checking carbon budgets, processing ecosystem gas-exchange data, comparing atmospheric-inversion results, using isotope data to identify sources, and evaluating Earth-system models.
Why use it?
It helps prevent mismatched definitions, signs, time periods, or missing flows from making a carbon budget appear to balance when it does not. It also separates measured values from estimates produced by models or gap-filling.

Plugin for Claude Code

Written for Claude Code: a Claude Code plugin manifest.

Security

Grade A, and why

carbon-cycle-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 5d 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 — 114 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

carbon-cycle-scientist is a plugin published in the GitHub repository K-Dense-AI/scientific-agents (168 stars, last pushed 20d 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.
