@uncaged/workflow-agent-claude-code

uwf-claude-code agent — spawns the Claude Code CLI and captures session detail.

Overview

Layer 3 agent implementation. Spawns the claude CLI with a composed system prompt (role definition, task, prior steps, edge prompt). Parses stream or JSON stdout, caches session IDs for multi-turn continuation, and stores raw output plus structured detail in CAS.

Dependencies: @uncaged/json-cas, @uncaged/workflow-util-agent

Installation

Included as the uwf-claude-code binary when you install @uncaged/workflow-agent-claude-code:

bun add -g @uncaged/workflow-agent-claude-code

Requires the claude CLI on PATH.

CLI Usage

Invoked by uwf thread step:

uwf-claude-code <thread-id> <role>

Configure or override the agent:

uwf setup --agent claude-code
uwf thread step <thread-id> --agent uwf-claude-code

Environment variables set by the engine:

| Variable | Purpose | |----------|---------| | UWF_EDGE_PROMPT | Moderator edge instruction for this step |

API

All exports come from src/index.ts.

Agent factory

function createClaudeCodeAgent(): () => Promise<void>
function buildClaudeCodePrompt(ctx: AgentContext): string

Session detail

function parseClaudeCodeStreamOutput(stdout: string): ClaudeCodeParsedResult | null
function parseClaudeCodeJsonOutput(stdout: string): ClaudeCodeParsedResult | null
function storeClaudeCodeDetail(
  store: Store,
  parsed: ClaudeCodeParsedResult,
  sessionId: string,
): Promise<string>
function storeClaudeCodeRawOutput(store: Store, rawOutput: string): Promise<string>

Usage (library)

import { createClaudeCodeAgent, buildClaudeCodePrompt } from "@uncaged/workflow-agent-claude-code";

const main = createClaudeCodeAgent();
void main();

Configuration

Uses session caching from @uncaged/workflow-util-agent (getCachedSessionId / setCachedSessionId). No separate config file — relies on the Claude Code CLI's own authentication.

Maximum turns per invocation: 90 (constant in claude-code.ts).
