Rust implementation status
AGL 0.6 is implemented by the native Rust compiler, checker, runtime, CLI, adapters, and embedding API. Rust is the sole language implementation.

Extension boundary
Rust accepts the checked-in .agent examples and is the implementation used by the conformance and regression suites. Applications extend it through Registry, ToolRegistry, and the extension traits in agl::extension.
Embedding
use agl::{check_program, execute_pipeline, parse_program, Registry};
use agl::context::ExecutionContext;
use std::collections::BTreeMap;
let program = parse_program(source)?;
check_program(&program)?;
let registry = Registry::default();
let value = execute_pipeline(
&program,
"pipeline_name",
BTreeMap::new(),
®istry,

The live-provider tests are intentionally ignored in ordinary runs because they require credentials and make billable network calls. Run them manually or through .github/workflows/live-smoke.yml before a provider release.
