Fields

tool_output_mode: ToolOutputMode

Tool output display mode (“compact” or “full”)

tool_output_max_lines: usize

Maximum number of lines to display in tool output (prevents transcript flooding)

tool_output_spool_bytes: usize

Maximum bytes of output to display before auto-spooling to disk

tool_output_spool_dir: Option<String>

Optional custom directory for spooled tool output logs

allow_tool_ansi: bool

Allow ANSI escape sequences in tool output (enables colors but may cause layout issues)

inline_viewport_rows: u16

Number of rows to allocate for inline UI viewport

reasoning_display_mode: ReasoningDisplayMode

Reasoning display mode for chat UI (“always”, “toggle”, or “hidden”)

reasoning_visible_default: bool

Default visibility for reasoning when display mode is “toggle”

status_line: StatusLineConfig

Status line configuration settings

keyboard_protocol: KeyboardProtocolConfig

Keyboard protocol enhancements for modern terminals (e.g. Kitty protocol)

layout_mode: LayoutModeOverride

Override the responsive layout mode

display_mode: UiDisplayMode

UI display mode preset (full, minimal, focused)

show_sidebar: bool

Show the right sidebar (queue, context, tools)

dim_completed_todos: bool

Dim completed todo items (- [x]) in agent output

message_block_spacing: bool

Add spacing between message blocks

minimum_contrast: f64

Minimum contrast ratio for text against background (WCAG 2.1 standard)

• 4.5: WCAG AA (default, suitable for most users)
• 7.0: WCAG AAA (enhanced, for low-vision users)
• 3.0: Large text minimum
• 1.0: Disable contrast enforcement

bold_is_bright: bool

Compatibility mode for legacy terminals that map bold to bright colors. When enabled, avoids using bold styling on text that would become bright colors, preventing visibility issues in terminals with “bold is bright” behavior.

safe_colors_only: bool

Restrict color palette to the 11 “safe” ANSI colors portable across common themes. Safe colors: red, green, yellow, blue, magenta, cyan + brred, brgreen, brmagenta, brcyan Problematic colors avoided: brblack (invisible in Solarized Dark), bryellow (light themes), white/brwhite (light themes), brblue (Basic Dark). See: https://blog.xoria.org/terminal-colors/

color_scheme_mode: ColorSchemeMode

Color scheme mode for automatic light/dark theme switching.

• “auto”: Detect from terminal (via OSC 11 or COLORFGBG env var)
• “light”: Force light mode theme selection
• “dark”: Force dark mode theme selection

Trait Implementations

impl Clone for UiConfig

fn clone(&self) -> UiConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UiConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UiConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UiConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for UiConfig

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for UiConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
