Module baseline 

Baseline agent — the canonical RustFn worker for bootstrap and smoke tests.

The library-layer source of truth that structurally removes the pattern of each binary (server / MCP adapter / one-shot runner) inlining its own “let’s just wire up a quick echo” duplicate. Same shape as enhance/blueprint.rs:

• Export the agent name as a role-literal const (AG_IDENTITY). The naming reflects the function itself — an identity / passthrough of ctx — and deliberately avoids demo / echo framing.
• Bake the real implementation (extend_with_baseline). Not a false-positive fake — a straightforward passthrough that returns the input prompt in the value field, so callers can build smoke tests around “the baseline agent exists”.
• A builder (extend_with_baseline) that adds the RustFn to an existing RustFnInProcessSpawnerFactory. Same shape as enhance::blueprint::extend_factory.

Usage

use mlua_swarm_engine_core::baseline::{extend_with_baseline, AG_IDENTITY};
use mlua_swarm_engine_core::RustFnInProcessSpawnerFactory;

let factory = extend_with_baseline(RustFnInProcessSpawnerFactory::new());
// The factory now has a RustFn registered under fn_id = AG_IDENTITY ("identity").

Blueprint flows reference it as spec: {"fn_id": baseline::AG_IDENTITY} (or the literal "identity").

Constants

AG_IDENTITY

The baseline RustFn agent name — "identity".

Functions

extend_with_baseline

Builder that adds the baseline RustFn to a base factory.
