@uncaged/workflow-util-agent

Shared helpers for CLI-backed workflow agents: assemble prompts from thread context and spawn subprocesses with timeouts.

Used by @uncaged/workflow-agent-cursor and @uncaged/workflow-agent-hermes. Depends on @uncaged/workflow for CAS reads (getContentMerklePayload) and Result typing.

Install

bun add @uncaged/workflow-util-agent @uncaged/workflow

In this monorepo: workspace:* for both packages.

Usage

import { buildAgentPrompt, spawnCli } from "@uncaged/workflow-util-agent";

const prompt = await buildAgentPrompt(agentContext);
const result = await spawnCli("my-cli", ["--json"], { cwd: "/tmp", timeoutMs: 60_000 });
if (!result.ok) { /* handle SpawnCliError */ }
const stdout = result.value;
