# Module LittleGhost::Content

Documentation version: Edge

Canonical HTML: https://littleghostai.org/docs/LittleGhost/Content.html

Content gives messages a shared vocabulary for text, attachments, tool calls,
tool results, and model reasoning. The same blocks move between agents,
providers, tools, and sessions without leaking a provider's wire format.

    block = LittleGhost::Content::Text.new(text: "Hello")
    LittleGhost::Content.normalize("Hello") == block # => true

Every block serializes through
[Content.serialize](Content.md#method-i-serialize). Binary data uses
strict base64 encoding in the serialized form.
