What it does

Gcb Study Design is an agent skill from franklee16/academic-research-skills. Use when designing the study behind a Global Change Biology (GCB) manuscript — manipulative experiments, observational/gradient studies, or process modelling of biological responses to global change. GCB reviewers probe scale, replication, realism, and causal inference. Guides design choices; it does not collect or simulate data.

Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Research & Science, covering Experimental design and Database administration. The repository describes itself as: Comprehensive collection of Claude Code skills for academic research in economics, finance, and social sciences.

When your agent uses it

  • Designing the study behind a Global Change Biology (GCB) manuscript — manipulative experiments
  • Observational/gradient studies
  • Process modelling of biological responses to global change

Example prompts

  • “/gcb-study-design”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Manipulative experiments (OTC/infrared warming, FACE/eCO2, rainfall manipulation, N addition,
  2. Observational / gradient & long-term studies (space-for-time, latitudinal/elevational gradients,
  3. Process / ecosystem & distribution models (DGVMs, soil-C, crop, SDM/niche). Document **version,
  4. Evidence synthesis / meta-analysis. Pre-specify the search protocol (PRISMA-style), inclusion

What it can do on your machine

Read from SKILL.md and the folder at commit 9a4b2db. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gcb Study Design loads about 894 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 304 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~894

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 304 words (~894 tokens).

“GCB reviewers are experts in ecology, biogeochemistry, and ecosystem/Earth-system modelling. They will probe whether the design can actually support a driver → biological-response claim at the stated scale. This skill covers design choices and their tradeoffs; analysis lives in gcb-data-analysis.”
