This Skill helps you represent computations that may succeed partially by returning both a value and an error, instead of forcing an all-or-nothing Result.
Use the tsentials/these skill to design a validation pipeline that collects warnings as errors while still returning successfully parsed values.

Use the These data structure to pair successful values with error information in one unified object. This lets you continue computation despite recoverable issues while still surfacing them for later inspection.
Railway-oriented programming in TypeScript structures functional pipelines to track both values and errors simultaneously. Use it for validation and rule-evaluation scenarios requiring partial success instead of all-or-nothing Result types.
Collect warnings while returning parsed values by mapping and flatMapping over a These structure. Transform either side while preserving the other, then pattern-match left, right, and both cases to extract the final outcomes.
Domain-driven design validation does not require all-or-nothing Result types. You can return both errors and values together using These constructors, enabling partial success modeling for complex rule-evaluation flows.
Convert a These structure into a Result by pattern-matching left, right, and both cases. Apply strict semantics to fail on any errors, or lenient semantics to return the value while ignoring accompanying recoverable issues.
Avoid partial success modeling when operations require hard failures or unrecoverable errors. If computation cannot safely proceed with recoverable issues, use standard Result types instead of These to halt the pipeline immediately.
