Usage

import { parse, parseSections, advance } from "@darkhorseprojects/circuitry";

const { definition, body } = parse(fs.readFileSync("agent.md", "utf8"));
const state = { document: input };
for (const [k, v] of Object.entries(parseSections(body))) state[k] = v;
while (await advance(definition, state, new Map())) {}

| Field | Description | |---|---| | source | Executable to run — path or global command. | | in | Inputs resolved from state. Supports $variable and $"## Heading". | | out | Template matched against the response, validated, then bound. | | url | Metadata for external update tooling. Ignored by the runner. |
