Struct SkillTool 

pub struct SkillTool {
    pub name: String,
    pub description: String,
    pub kind: String,
    pub command: String,
    pub args: HashMap<String, String>,
    pub target: Option<String>,
    pub locked_args: HashMap<String, String>,
}

A tool defined by a skill (shell command, HTTP call, etc.)

Fields

name: String

description: String

kind: String

“shell”, “http”, “script”, “builtin”, “mcp”

command: String

The command/URL/script to execute (unused for builtin/mcp kinds)

args: HashMap<String, String>

target: Option<String>

For kind = "builtin": the name of the built-in tool to delegate to. For kind = "mcp": the prefixed MCP tool name {server}__{tool} (e.g. images__generate).

locked_args: HashMap<String, String>

For kind = "builtin" / kind = "mcp": arguments fixed by the skill manifest. These are locked — they are applied on top of the caller-supplied args and cannot be overridden by the model. This is what scopes a delegated tool (e.g. target = "composio" + locked_args = { action_name = "TEXT_TO_PDF" } exposes exactly one action). Accepts the legacy key default_args for compatibility.
