Agentic Graph Specification for Rust

Native Rust support for Agentic Graph Specification 1.0. The crate provides the same conformance-level-0 surface as the Python, TypeScript, and Go libraries:

• YAML 1.2 and JSON parsing with duplicate-key rejection;
• embedded JSON Schema plus semantic and AGX dataflow validation;
• RFC 8785 canonical JSON and SHA-256 graph identities;
• AGX parsing with function-call and reference collection;
• effective-edge calculation and deterministic topological ordering;
• deterministic, non-executing Level 0 plans; and
• the ags-validate CLI.

The MSRV is Rust 1.85.0 and the crate uses edition 2024.

use agentic_graph_spec::{load, graph_digest, plan_graph, validate};

let graph = load("graph.agraph.yaml")?;
let report = validate(&graph);
assert!(report.ok, "{:?}", report.errors);
println!("{}", graph_digest(&graph)?);
println!("{:?}", plan_graph(&graph)?.order);
# Ok::<(), Box<dyn std::error::Error>>(())

cargo install agentic-graph-spec --version 1.0.3
ags-validate --strict graph.agraph.yaml

This library validates and plans graphs; it does not execute them.
