Package Exports

@yuaone/core
@yuaone/core/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@yuaone/core) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

import { AgentLoop, createAgentLoop } from "@yuaone/core";

const loop = createAgentLoop({
  provider: "anthropic",
  apiKey: process.env.ANTHROPIC_API_KEY,
  model: "claude-sonnet-4-6",
  workDir: process.cwd(),
});

for await (const event of loop.run("refactor auth.ts to async/await")) {
  if (event.kind === "agent:token") process.stdout.write(event.content);
  if (event.kind === "agent:completed") break;
}

`ContinuationEngine`	Checkpoint every 3 iters, recovery on error
`ReflexionEngine`	Per-iteration self-reflection & insight injection
`WorldStateCollector`	Tracks file changes across iterations
`QAPipeline`	Quick + thorough quality checks post-execution
`Governor`	Safety/security scanning before tool execution
`AutoFix`	Automatic lint/type error repair
`ContextManager`	Token budget management & compaction
