Struct Skill 

pub struct Skill {
    pub name: String,
    pub description: String,
    pub template: String,
    pub disable_model_invocation: bool,
    pub user_invocable: bool,
    pub argument_hint: Option<String>,
    pub allowed_tools: Vec<String>,
    pub skill_dir: PathBuf,
    pub source_path: PathBuf,
}

A loaded skill parsed from a SKILL.md or legacy .md file.

Fields

name: String

Command name without leading slash, e.g. “commit” or “superpowers:brainstorming”.

description: String

Human-readable description (frontmatter > first paragraph of template).

template: String

Raw template content (everything after the frontmatter block).

disable_model_invocation: bool

If true, hidden from Claude’s context — user must invoke manually via /name.

user_invocable: bool

If false, hidden from the / menu — Claude can still invoke automatically.

argument_hint: Option<String>

Autocomplete hint shown next to the skill name, e.g. “[issue-number]”.

allowed_tools: Vec<String>

Tools auto-approved when this skill is active.

skill_dir: PathBuf

Directory containing the skill file (used for ${CLAUDE_SKILL_DIR} substitution).

source_path: PathBuf

Source file path, for diagnostics.

Implementations

impl Skill

pub fn expand(&self, arguments: &str, session_id: &str) -> String

Expand the template, applying all substitutions in order:

1. $ARGUMENTS[N] → positional argument by 0-based index
2. $N → shorthand for $ARGUMENTS[N]
3. $ARGUMENTS → all arguments (appended as ARGUMENTS: … if absent)
4. ${CLAUDE_SESSION_ID} → the provided session id
5. ${CLAUDE_SKILL_DIR} → absolute path of the skill’s directory
6. !`command` → preprocess: run shell command, insert stdout
