Randomization Gen

RCT randomization table generator.

Use Cases

• Clinical trial design
• Animal study randomization
• Blocked randomization
• Stratified allocation

Parameters

Parameter	Type	Required	Description
n_subjects	int	Yes	Total sample size
n_groups	int	Yes	Number of arms/groups
block_size	int	Yes	Block size (must be multiple of n_groups)
--output	string	No	Output file path (default: randomization.txt)

Returns

• Randomization sequence
• Block assignments
• Allocation concealment ready

Example

Input: n=120, 3 groups, block=6 Output: Sealed randomization list

Risk Assessment

Risk Indicator	Assessment	Level
Code Execution	Python/R scripts executed locally	Medium
Network Access	No external API calls	Low
File System Access	Read input files, write output files	Medium
Instruction Tampering	Standard prompt guidelines	Low
Data Exposure	Output files saved to workspace	Low

Security Checklist

• No hardcoded credentials or API keys
• No unauthorized file system access (../)
• Output does not expose sensitive information
• Prompt injection protections in place
• Input file paths validated (no ../ traversal)
• Output directory restricted to workspace
• Script execution in sandboxed environment
• Error messages sanitized (no stack traces exposed)
• Dependencies audited

Prerequisites

No additional Python packages required.
