Struct Skill 

pub struct Skill {
    pub name: String,
    pub description: String,
    pub prompt: String,
    pub arguments: Vec<SkillArgument>,
    pub config: Option<SlotConfig>,
    pub scope: SkillScope,
    pub argument_hint: Option<String>,
    pub skill_dir: Option<PathBuf>,
}

A reusable skill template.

Fields

name: String

Unique skill name (e.g. “code_review”, “write_tests”).

description: String

Human-readable description of what this skill does.

prompt: String

Prompt template. Use {arg_name} placeholders for arguments.

arguments: Vec<SkillArgument>

Argument definitions (name -> description).

config: Option<SlotConfig>

Per-skill config overrides (model, effort, etc.).

scope: SkillScope

Where this skill is intended to run (advisory).

argument_hint: Option<String>

Hint shown in skill listings to indicate expected arguments.

Follows the Agent Skills standard argument-hint field. Example: "[issue-number]", "<file> [--verbose]".

skill_dir: Option<PathBuf>

Path to the skill’s directory on disk.

Set when loaded from a SKILL.md folder (project or global skills). Used for ${CLAUDE_SKILL_DIR} substitution in prompts, allowing skills to reference bundled scripts and supporting files. None for builtins and runtime-added skills.

Implementations

pub fn render(&self, args: &HashMap<String, String>) -> Result<String>
