Randomization Gen

RCT randomization table generator.

Use Cases

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

Parameters

Parameter	Type	Required	Description
INLINECODE0	int	Yes	Total sample size
INLINECODE1

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.

Evaluation Criteria

Success Metrics

• [ ] Output meets quality standards
• [ ] Handles edge cases gracefully
• [ ] Performance is acceptable

Test Cases

1. 1. Basic Functionality: Standard input → Expected output
2. Edge Case: Invalid input → Graceful error handling
3. Performance: Large dataset → Acceptable processing time

Lifecycle Status
