xiaoju 54dc8fcb39 fix(validate): support enum-based multi-exit and upgrade json-cas to 0.5.3
Two fixes for 'uwf thread start solve-issue' failures:

1. json-cas 0.5.2 (npm) was missing oneOf in ALLOWED_SCHEMA_KEYS.
   Published json-cas 0.5.3 with the fix, bumped all packages to ^0.5.3.

2. Semantic validator only recognized oneOf-based multi-exit schemas.
   Roles using $status with enum (e.g. enum: [approved, rejected]) were
   incorrectly treated as single-exit. Added isEnumMultiExit() support.

Changes:
- validate-semantic.ts: isEnumMultiExit(), getEnumStatuses(), checkSingleExitMustache()
- All package.json: @uncaged/json-cas ^0.5.2 → ^0.5.3
- validate-semantic.test.ts: 5 new enum multi-exit tests (Suite 3b)
- solve-issue-tea-worktree.test.ts: updated for current workflow structure

@uncaged/workflow-agent-hermes

uwf-hermes agent — spawns Hermes chat via ACP and captures session detail.

Overview

Layer 3 agent implementation. Wraps the Hermes CLI using the Agent Client Protocol (ACP). On first visit to a role it sends a composed prompt (role definition, task, history, edge prompt); on continuation it resumes the cached session. Session transcripts and raw output are stored as CAS detail nodes.

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

Installation

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

bun add -g @uncaged/workflow-agent-hermes

Requires the hermes CLI on PATH.

CLI Usage

Invoked by uwf thread step (not typically run directly):

uwf-hermes <thread-id> <role>

Environment variables set by the engine:

Variable Purpose
UWF_EDGE_PROMPT Moderator edge instruction for this step

Configure as the default agent via uwf setup --agent hermes.

Override per step:

uwf thread step <thread-id> --agent uwf-hermes

API

All exports come from src/index.ts.

Agent factory

function createHermesAgent(): () => Promise<void>
function buildHermesPrompt(ctx: AgentContext): string

ACP client

class HermesAcpClient {
  // Spawns hermes, handles JSON-RPC over stdio
}

Usage (library)

import { createHermesAgent, buildHermesPrompt } from "@uncaged/workflow-agent-hermes";

// CLI entry (src/cli.ts):
const main = createHermesAgent();
void main();

Configuration

Uses workflow config from ~/.uncaged/workflow/config.yaml (via agent-kit). Hermes session files are stored under the workflow storage root (see session-detail.ts).

Set UWF_HERMES_NO_RESUME=1 to disable session resume (see isResumeDisabled in session-cache.ts).
