Comprehensive skill for the Literal Ruby gem (https://literal.fun) by Joel Drapper. Use when writing or reviewing Ruby code that uses Literal - typed properties via `prop`/`prop?`, runtime type matchers `_Array`/`_Union`/`_Map`/etc., structured objects (`Literal::Struct`, `Literal::Data`), value objects (`Literal::Value`, `Literal::Delegator`), enums (`Literal::Enum`), bitfield flags (`Literal::Flags`), generic collections (`Literal::Array(...)`, `Set`, `Hash`, `Tuple`), result monads (`Literal::Result`, `Success`, `Failure`), or JSON-style serialization. Also use when designing typed APIs in plain Ruby without external type checkers.

From the source SKILL.md

Literal is a runtime type system for Ruby. It checks types when objects are constructed and when methods are called - no separate type checker needed. The library also provides building blocks for structured objects (Struct/Data), value objects, enums, flags, generic collections, and result monads.

What this skill does

Literal is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/literal/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when writing or reviewing Ruby code that uses Literal - typed properties via `prop`/`prop?`, runtime type matchers `_Array`/`_Union`/`_Map`/etc., structured objects (`Literal::Struct`, `Literal::Data`), value objects (`Literal::Value`, `Literal::Delegator`), enums (`Literal::Enum`), bitfield flags (`Literal::Flags`), generic collections (`Literal::Array(.

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Literal skill?
Use Literal when your Claude Code task falls under the General category — specifically in the general misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Literal" or describe the task and let Claude pick). Browse related skills at /category/general/.
What is a Claude Code skill and how does the Literal skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Literal is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
