Module context 

Context Provider Extension Point

This module provides the extension point for integrating context databases like OpenViking into the agent loop. Context providers can supply memory, resources, and skills to augment the LLM’s context.

Usage

Implement the ContextProvider trait and register it with a session:

use a3s_code::context::{ContextProvider, ContextQuery, ContextResult};

struct MyProvider { /* ... */ }

#[async_trait::async_trait]
impl ContextProvider for MyProvider {
    fn name(&self) -> &str { "my-provider" }

    async fn query(&self, query: &ContextQuery) -> anyhow::Result<ContextResult> {
        // Retrieve relevant context...
    }
}
