How does this skill handle missing or optional JSON fields?

The skill provides patterns using `opt_mem` to handle optional fields and `Option.value` to provide defaults, as well as `skip_unknown` to safely ignore extra fields in a JSON object.

What is the OCaml jsont skill for?

It is a specialized capability that helps Claude generate OCaml code for encoding and decoding JSON using the jsont library, ensuring your data mappings are type-safe and idiomatic.

Does it support custom OCaml types like enums?

Absolutely. It utilizes `Jsont.map` to transform basic JSON types into custom OCaml variants or enums during the decoding process.

Can I use this for complex, nested JSON objects?

Yes, the skill includes patterns for composing smaller codecs into larger, nested structures, making it easy to model complex API responses.

API Development

Generates and manages type-safe JSON encoding and decoding for OCaml record types using the jsont library.

About

The jsont skill empowers Claude to assist OCaml developers in building robust, type-safe JSON interfaces using Daniel Bünzli's jsont library. It streamlines the creation of complex codecs for OCaml record types, handles nested structures, and provides implementation patterns for optional fields and backwards-compatible parsing. This skill is essential for OCaml developers building REST APIs, CLI tools, or any application requiring reliable data serialization without sacrificing OCaml's strong type guarantees.

Key Features
