System message = agent identity (role prompt + output format instruction)
User message = moderator speech (task + edge prompt + history)
This reflects the workflow's core model: moderator speaks to agent
via the graph's edge prompt. Previously all content was in a single
system message with no user message, causing Claude API 400 errors.
- buildBuiltinPrompt now returns { system, user } instead of string
- agent.ts sends system + user as separate messages
- Tests updated accordingly
@uncaged/workflow
A stateless workflow engine driven by a single-step CLI. Workflows are YAML definitions with roles, JSONata routing conditions, and a directed graph. Threads are immutable CAS-linked chains — each uwf thread step runs one moderator→agent→extract cycle and exits.

Quick Start
# 1. Configure provider and model
uwf setup
# 2. Register a workflow from YAML
uwf workflow put examples/solve-issue.yaml
# 3. Start a thread
uwf thread start solve-issue -p "Fix the login redirect bug"
# 4. Execute steps (one at a time, until done)
uwf thread step <thread-id>
