Function enhance_prompt_with_llm 

pub async fn enhance_prompt_with_llm(
    prompt: &str,
    config: &AppConfig,
    context: Option<PromptContext>,
) -> Result<String, AppError>

Enhance a user prompt using the configured LLM provider

This function takes a user’s prompt and uses an LLM to improve it by:

• Adding relevant context and specificity
• Structuring complex requests into clear steps
• Including success criteria when appropriate
• Maintaining the user’s original intent and tone
• Leveraging provided context (session history, files, project info)

Arguments

• prompt - The original user prompt to enhance
• config - Application configuration (for LLM provider selection)
• context - Optional context information (session history, files, etc.)

Returns

Returns the enhanced prompt as a String, or an error if enhancement fails.

Example

use gestura_core::prompt_enhancement::{enhance_prompt_with_llm, PromptContext};
use gestura_core::config::AppConfig;
use gestura_core::AppConfigSecurityExt;

let config = AppConfig::load_async().await;
let original = "fix the bug";

// Without context
let enhanced = enhance_prompt_with_llm(original, &config, None).await?;

// With context
let context = PromptContext::new()
    .with_session_history(vec![
        ("user".to_string(), "I'm working on the login feature".to_string()),
        ("assistant".to_string(), "I can help with that".to_string()),
    ]);
let enhanced = enhance_prompt_with_llm(original, &config, Some(context)).await?;

println!("Enhanced: {}", enhanced);
