Run deterministic multi-step agent workflows in Codex - fan-out, parallel, schema-validated structured output - via the codex-workflow MCP orchestrator (run_workflow), with native in-chat fallbacks. Use when you want Claude-Code-Workflow-style orchestration in Codex: 'run a workflow', 'fan out subagents', 'review each file in parallel', 'orchestrate these steps'. Triggers: 'codex-workflow', 'run_workflow', 'orchestrate in codex'.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex Workflow
Deterministic multi-agent orchestration in Codex - the analog of Claude Code's Workflow tool. Pick the right level for the job.
## Three levels (cheapest first)
| Need | Use | Determinism |
|---|---|---|
| Ad-hoc "spawn one agent per X, summarize" in a chat | **native NL spawn** | low (model decides) |
| Fixed fan-out over a worklist (one worker per row, schema'd) | **`spawn_agents_on_csv`** | medium |
| Collision-free parallel *implementation* | **`worktree + codex exec &`** | high (isolated) |
| Scripted multi-step pipeline with structured output you parse | **`run_workflow`** (the orchestrator MCP) | high |
Reach for `run_workflow` when you'd otherwise hand-wire `codex exec` calls; reach for the native paths for quick in-session work.
## `run_workflow` - the orchestrator
Installed as the `codex-workflow` MCP extension (`vd mcp install codex-workflow`). Call the `run_workflow` tool with a spec:
```jsonc
{
"steps": [
{ "id": "scan", "prompt": "List changed files vs main.", "output_schema": {"type":"object","properties":{"files":{"type":"array"}}} },
…Read the whole file at its exact version.
How to install
mdr add vanducng/skills/codex-workflow@sha256:aeca107e45bcf07cThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
