Expand description

Applies simple transformations to prompt templates.

Implementations§

Source§

impl PromptMutator

Source

pub fn paraphrase(template: &str, seed: u64) -> String

Replace 2–3 common words with synonyms and return the modified template.

Uses a small hardcoded thesaurus. Deterministic for a given seed.

Source

pub fn add_instruction(template: &str, instruction: &str) -> String

Prepend an instruction to the template.

Source

pub fn trim_to_budget(template: &str, max_tokens: usize) -> String

Truncate the template to approximately max_tokens tokens (1.3 tokens/word).
