# `Lightning.AiAssistant.ChatMessage.Segment`
[🔗](https://github.com/OpenFn/lightning/blob/main/lib/lightning/ai_assistant/chat_message.ex#L36)

One entry in an assistant reply's display timeline: a chunk of answer
text, or a completed-action status ("Added step send-to-gmail...") woven
between texts in stream order. Display-only — the flat `content` field
stays the canonical answer.

# `t`

```elixir
@type t() :: %Lightning.AiAssistant.ChatMessage.Segment{
  content: String.t(),
  steps: [Lightning.AiAssistant.ChatMessage.Segment.Step.t()],
  summary: String.t() | nil,
  type: :text | :status
}
```

# `max_content_length`

Maximum length of a single segment's content (matches `content`'s cap).

# `max_step_field_length`

Maximum length of a step's key or name.

# `max_steps`

Maximum number of steps recorded against one status segment.
