Data & Search MIT E1 · source linked

`server/index.ts` is a small Bun server that serves `dist/` and the `/api/jev` proxy, which uses the same forwarding code as dev (`server/jev-upstream.ts`). Because the live proxy spends real credits, it only accepts same-origin POSTs from the app, pins the model, caps request size, and rate-limits each IP.

Creative Tools MIT E1 · source linked

TypeSafe's `/v1/systemone` endpoint classifies text — it returns a `choice`, a `score`, or a probability. It does not generate prose. This library makes it generate prose anyway: every word of the answer is a separate `choice` question over a vocabulary, and the loop feeds its own output back in as the prefix.

Security & Guardrails MIT E1 · source linked

When FarHand is active, the agent's commands run on a remote host through the `farhand_remote_shell` MCP tool instead of `shell`. OpenCode's permission request for an MCP tool carries no arguments, so the plugin takes the command (and its `cwd`) from the `execute.before` hook, which OpenCode runs first.
