Struct CapabilitiesConfig 

pub struct CapabilitiesConfig {
    pub enable_subagents: bool,
    pub enabled_tools: Option<Vec<BuiltinTools>>,
    pub disabled_tools: Option<Vec<BuiltinTools>>,
    pub compaction_threshold: Option<usize>,
    pub image_model: String,
    pub finish_tool_schema_json: Option<String>,
}

Agent capability toggles: tool allowlists, subagent support, and compaction.

Fields

enable_subagents: bool

Whether this agent can spawn subagents.

enabled_tools: Option<Vec<BuiltinTools>>

If set, only these built-in tools are available (allowlist).

disabled_tools: Option<Vec<BuiltinTools>>

If set, these built-in tools are removed (denylist).

compaction_threshold: Option<usize>

Token threshold that triggers conversation compaction.

image_model: String

The model to use for image generation.

This setting is a shorthand for GeminiConfig.models.image_generation.name. If both are specified, the value in GeminiConfig takes precedence and this field is ignored.

finish_tool_schema_json: Option<String>

Optional JSON schema string for the finish tool’s structured output.

Implementations

impl CapabilitiesConfig

pub fn with_tools(tools: Vec<BuiltinTools>) -> Self

Create a capabilities config with only the specified tools enabled.

Subagent support is enabled by default.

pub fn full() -> Self

Create a capabilities config with all tools and subagent support.

pub fn read_only() -> Self

Create a capabilities config for read-only agents with subagent support.

pub fn custom_tools_only() -> Self

Create a capabilities config with no builtin tools — only custom tools.

Subagent support is still enabled.

pub const fn validate(&self) -> Result<(), &'static str>

Errors

Returns an error if enabled_tools and disabled_tools are both provided.
