- Lock study design and mandatory prospective registration for a Lancet clinical manuscript — trial registration before enrollment

What it does
Lancet Study Design is an agent skill from franklee16/academic-research-skills. Use to lock study design and mandatory prospective registration for a Lancet clinical manuscript — trial registration before enrollment, protocol + statistical analysis plan, and design rigor (randomization, allocation concealment, blinding, pre-specified endpoints, power, ITT). Covers observational design choices too.
Its SKILL.md is about 1.2k 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 Statistics. 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
- Lock study design and mandatory prospective registration for a Lancet clinical manuscript — trial registration before enrollment
- Protocol + statistical analysis plan
- Design rigor (randomization
- Allocation concealment
Example prompts
- “/lancet-study-design”
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
Links to these hosts (documentation or services it may open):
clinicaltrials.govisrctn.comtrialsearch.who.int
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
Lancet Study Design loads about 1.2k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 417 words of instructions outside code blocks.
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 417 words (~1,157 tokens).
“The Lancet follows ICMJE: clinical trials must be registered prospectively — before the first participant is enrolled — in a WHO-ICTRP primary registry or ClinicalTrials.gov.”
