What it does
Tooluniverse Clinical Trial Design is an agent skill from wu-yc/LabClaw. Strategic clinical trial design feasibility assessment using ToolUniverse. Evaluates patient population sizing, biomarker prevalence, endpoint selection, comparator analysis, safety monitoring, and regulatory pathways. Creates comprehensive feasibility reports with evidence grading, enrollment projections, and trial design recommendations. Use when planning Phase 1/2 trials, assessing trial feasibility, or designing biomarker-driven studies.
Its SKILL.md is about 11k 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. The repository describes itself as: LabClaw – Operating Layer for LabOS (Stanford-Princeton AI Co-Scientists).
When your agent uses it
- Planning Phase 1/2 trials
- Assessing trial feasibility
- Designing biomarker-driven studies
Example prompts
- “/tooluniverse-clinical-trial-design”
Requirements
- Python 3
Workflow steps
12 steps, taken from the step headings in SKILL.md.
- Report-First Approach (MANDATORY)
- Evidence Grading System
- Feasibility Score (0-100)
- Executive Summary
- Disease Background
- Patient Population Analysis
- Biomarker Strategy
- Endpoint Selection & Justification
- Comparator Analysis
- Safety Endpoints & Monitoring Plan
- Enrollment & Site Strategy
- Regulatory Pathway
What it can do on your machine
Read from SKILL.md and the folder at commit df37802. 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 (its code samples are markdown and python).
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):
zitniklab.hms.harvard.edufda.govclinicaltrials.govjoin.slack.com
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
Tooluniverse Clinical Trial Design loads about 11k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 1,304 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 1,304 words (~10,735 tokens).
“Systematically assess clinical trial feasibility by analyzing 6 research dimensions. Produces comprehensive feasibility reports with quantitative enrollment projections, endpoint recommendations, and regulatory pathway analysis.”
