Smithers · v0.23.0

# Describe a workflow.
Smithers builds it.

The new create-workflow metaworkflow turns a plain-English ask into a runnable workflow: clarify the spec, design the graph, scaffold real files, verify until it compiles, then write the skill that documents it.
clarify→ design→ scaffold→ verify→ document
$ bunx smithers-orchestrator init # seeds create-workflow

New · Persistence

## Run Smithers on Postgres.

your hand-written SQL →
SQLite bun:sqlite PGlite embedded, in-process PostgreSQL managed, production
One dialect seam runs that exact SQL across all three with no query rewrites. Develop against an in-process PGlite, deploy against managed Postgres, same code.

Agents

## Any agent. Any MCP server.

Claude Code Codex Gemini Antigravity Hermes Vibe (Mistral)
Every agent runs behind the same durable engine. New this release: a Vibe (Mistral) agent and a corrected Antigravity CLI. And createMcpToolset connects any stdio MCP server, projecting its tools straight into an SDK agent.
const { tools } = await createMcpToolset({ command, args })

New · Custom Workflow UIs

## Workflows ship their own UI.

A workflow registers a browser UI through the Gateway, served at /workflows/<key> with live run, event, and node-output hooks over real RPC.
gateway.register({ ui: { entry } })
UltraGrill is the showcase: an open-ended real-time collaboration workflow with a live custom UI, launched with one command.
$ bun .smithers/scripts/ultragrill.ts "ship the landing page"

New · Human in the loop

## Let an agent stop and ask a person.

blocked→ ask_human→ waits→ answer→ resumes
When an agent is blocked, uncertain, or about to do something irreversible, it raises a durable request and blocks until a human answers. Available as the ask-human CLI and the ask_human MCP tool.
$ bunx smithers-orchestrator ask-human "Which DB should I target?" --choices sqlite,postgres

New · Zero-install VCS

## jj, bundled.

darwin-arm64 darwin-x64 linux-arm64 linux-x64 win32-x64
Smithers ships a jj binary per platform, so worktree snapshots and forks work with no system install. A package manager pulls only the one matching your host, and the doctor tells you up front when no usable git or jj is present.
$ bunx smithers-orchestrator workflow doctor # vcs: ok
