Struct Skill 

pub struct Skill<'a> { /* private fields */ }

A reusable instruction that gets injected into LLM prompts.

Skills provide persistent context — domain rules, coding conventions, or any instruction the LLM should follow across all prompts.

Implementations

impl<'a> Skill<'a>

pub fn new() -> Self

Create a new empty skill.

pub fn instruct(self, label: &'a str, instruction: &'a str) -> Self

Add an instruction with default priority (128).

pub fn instruct_at( self, label: &'a str, instruction: &'a str, priority: u8, ) -> Self

Add an instruction with explicit priority (lower = earlier in prompt).

pub fn instruct_owned(self, label: String, instruction: String) -> Self

Add an instruction from owned strings with default priority (128).

pub fn instruct_owned_at( self, label: String, instruction: String, priority: u8, ) -> Self

Add an instruction from owned strings with explicit priority.

pub fn render(&self) -> String

Render all instructions into a prompt section.

Instructions are sorted by priority (lowest first). Returns an empty string if there are no instructions.

pub fn instruct_if( self, cond: bool, label: &'a str, instruction: &'a str, ) -> Self

Conditionally add an instruction.

Only adds the instruction if cond is true.

pub fn merge(self, other: &Skill<'a>) -> Self

Merge another skill into this one.

Instructions from other are appended. If other has an instruction with the same label as one already in self, the one from other replaces it (last-writer-wins).

pub fn len(&self) -> usize

Number of instructions.

pub fn is_empty(&self) -> bool

Check if there are no instructions.

Trait Implementations

impl<'a> Default for Skill<'a>

fn default() -> Self

Returns the “default value” for a type.
