Initial import of all source code, config, and README assets: the packages workspace (cli, core, server, web, docs, landing, skills), build scripts, tooling config, and CI workflows. Includes the data-layout revision made on this branch: the local data root defaults to ~/.penguin/data (PENGUIN_HOME still overrides; the installer keeps its binaries in ~/.penguin), and every Agent lives under <project>/agents/<agent>/ — path helpers, the three agent-enumeration scans, the system prompt, built-in Skills, tests and docs all follow the new layout.

# @prismshadow/penguin-core
|
|
|
|
The PenguinHarness SDK and execution engine: the ReAct loop (`context_engine`), the OmniMessage protocol, the LLM / Environment interface contracts, Agent State and append-only Traces.
|
|
|
|
The engine speaks only OmniMessage and delegates everything else through two swappable interfaces — `LLMInterface` (models, via the [`@prismshadow/agenthub`](https://www.npmjs.com/package/@prismshadow/agenthub) gateway) and `EnvironmentInterface` (tool execution). The SDK caller is the Human boundary: one entry point, `session.run`, streams the whole loop.
|
|
|
|
```ts
|
|
import { createAgent, isCompleteModelMessage, userText } from "@prismshadow/penguin-core";
|
|
|
|
const agent = await createAgent({ agentId: "default_agent" });
|
|
const session = await agent.createSession({ workspaceDir: process.cwd() });
|
|
|
|
for await (const output of session.run([userText("Create hello.txt containing hi")], {
|
|
approve: async () => "allow", // per-tool-call approval
|
|
})) {
|
|
if (isCompleteModelMessage(output) && output.payload.type === "text") {
|
|
console.log(output.payload.text);
|
|
}
|
|
}
|
|
```
|
|
|
|
A single `run` drives a complete Task: streaming output, per-call approvals, concurrent tool execution, interrupt carry-over, automatic reconnect and context compaction. State lives under `~/.penguin/data` (`PENGUIN_HOME`); every Session restores fully from its Trace.
