@united-workforce/cli

uwf CLI — thread lifecycle, workflow registry, CAS inspection, and setup.

Overview

Layer 4 entry point for the workflow engine. The uwf binary orchestrates one step per invocation: load thread head from threads.yaml, run the moderator, spawn the configured agent CLI, run extract, append a CAS step node, and update the head pointer (or archive when $END).

Four-Layer Architecture

workflow → thread → step → turn
模板定义   执行实例   单步结果   agent内部交互

• Workflow (layer 1): YAML template with roles and routing graph
• Thread (layer 2): Single workflow execution instance
• Step (layer 3): One moderator→agent→extract cycle
• Turn (layer 4): Agent-internal interactions (use step show or CAS to inspect)

This package has no library src/index.ts — it is consumed as a CLI binary only.

Dependencies: @ocas/core, @ocas/fs, @united-workforce/util-agent, @united-workforce/protocol, @united-workforce/util, commander, dotenv, mustache, yaml

Installation

Included as the uwf binary when you install @united-workforce/cli:

bun add -g @united-workforce/cli
# or from the monorepo:
bun link packages/cli

Thread (Layer 2: Execution Instances)

Command	Description
uwf thread start <workflow> -p <prompt>	Create a thread without executing
uwf thread exec <thread-id> [--agent <cmd>] [-c <count>] [--background]	Execute one or more moderator→agent→extract cycles
uwf thread show <thread-id>	Show thread head pointer
uwf thread list [--status <status>] [--all] [--after <date>] [--before <date>] [--skip <n>] [--take <n>]	List threads (defaults to active: idle + running). Use --all to include completed/cancelled/suspended, or --status to filter explicitly (idle, running, suspended, completed, cancelled, active, or comma-separated). Supports time range and pagination.
uwf thread read <thread-id> [--quota N] [--before <hash>] [--start]	Render thread as readable markdown

thread read, step list, and step show work on both active and completed threads. | uwf thread stop <thread-id> | Stop background execution (keep thread active) | | uwf thread cancel <thread-id> | Cancel thread (stop + archive to history) |

Examples:

uwf thread start solve-issue -p "Fix the login redirect bug"
uwf thread exec 01ARZ3NDEKTSV4RRFFQ69G5FAV
uwf thread exec 01ARZ3NDEKTSV4RRFFQ69G5FAV -c 3 --agent uwf-builtin
uwf thread exec 01ARZ3NDEKTSV4RRFFQ69G5FAV --background
uwf thread list
uwf thread list --all
uwf thread list --status running
uwf thread list --status active
uwf thread list --status idle,completed
uwf thread list --after 7d --take 10
uwf thread read 01ARZ3NDEKTSV4RRFFQ69G5FAV --quota 8000
uwf thread stop 01ARZ3NDEKTSV4RRFFQ69G5FAV

Step (Layer 3: Single Cycle Results)

Command	Description
uwf step list <thread-id>	List all steps in a thread chronologically
uwf step show <step-hash>	Show step metadata and frontmatter
uwf step read <step-hash> [--quota <chars>]	Read a step's turns as human-readable markdown
uwf step fork <step-hash>	Fork a thread from a specific step
uwf step ask <step-hash> -p <prompt> [--agent <cmd>] [--no-fork]	Ask a follow-up question to a historical step's agent (read-only; no thread mutation)

Examples:

uwf step list 01ARZ3NDEKTSV4RRFFQ69G5FAV
uwf step show 32GCDE899RRQ3
uwf step read 32GCDE899RRQ3 --quota 2000
uwf step fork 32GCDE899RRQ3
uwf step ask 32GCDE899RRQ3 -p "Why did you choose this approach?"
uwf step ask 32GCDE899RRQ3 -p "Summarise the key findings" --no-fork

Workflow (Layer 1: Templates)

Command	Description
uwf workflow add <file.yaml>	Register a workflow from YAML
uwf workflow show <name-or-hash>	Show workflow definition
uwf workflow list	List registered workflows

CAS

Use the ocas CLI for direct CAS operations (~/.ocas/ store, shared with uwf):

Command	Description
ocas get <hash> [--timestamp]	Read a CAS node
ocas put <type-hash> <data>	Store a node, print hash
ocas has <hash>	Check existence
ocas refs <hash>	List direct references
ocas walk <hash>	Recursive traversal
ocas reindex	Rebuild type index
ocas schema list	List registered schemas
ocas schema get <hash>	Show a schema

Setup

uwf setup
uwf setup --provider openai --base-url https://api.openai.com/v1 \
  --api-key sk-... --model gpt-4o --agent hermes

Config: ~/.uwf/config.yaml (includes API keys).

Skill

Command	Description
uwf skill cli	Print markdown reference of all uwf commands (for agent skills)

Log

Command	Description
uwf log list	List log files with sizes
uwf log show [--thread <id>] [--process <pid>] [--date YYYY-MM-DD]	Show filtered log entries
uwf log clean [--before YYYY-MM-DD]	Delete old log files

Migration Guide

Breaking Changes (v0.x → v1.x)

The CLI was reorganized to clarify the four-layer architecture. No backward compatibility — old commands have been removed.

Renamed Commands

Old Command	New Command	Notes
workflow put	workflow add	More intuitive verb
thread step	thread exec	Eliminates ambiguity with "step" noun
thread list --all	thread list --status completed	Unified status filtering

Removed Commands (Merged)

Old Command	New Command	Notes
thread running	thread list --status running	Merged into unified list

Removed Commands (Split)

Old Command	New Commands	Notes
thread kill	thread stop or thread cancel	stop keeps thread active, cancel archives it

Moved Commands

Old Command	New Command	Notes
thread steps	step list	Moved to step layer
thread step-details	step show	Moved to step layer
thread fork	step fork	Moved to step layer (forks are step-based)

Deprecation Errors

Old commands now show helpful error messages:

$ uwf thread step 01ARZ3NDEKTSV4RRFFQ69G5FAV
Error: Command 'thread step' has been removed.
Use 'thread exec' instead.
