Select YAML values with a bounded path

Navigate mapping keys and sequence indexes with a deliberately small path language, then serialize the selected value for inspection.

What this tool does

Strict, bounded, local processing

This route is deterministic property navigation, not a general expression evaluator. It accepts no functions, predicates, scripts, or regular expressions.

A small selector keeps behavior inspectable

Property segments select mapping values and numeric index segments select sequence items. Bracket notation handles keys that cannot be represented safely as simple dot segments.

The engine reports a missing segment with its safe path location. It does not evaluate arbitrary code or turn scalar content into another expression.

Selection does not mutate the source

The chosen value is serialized into a separate result. Use the merge or flatten routes when the desired job is to create a changed document rather than inspect one location.
