## What it does

The skill treats a Scenario workflow as one document, `editor_info`, holding `nodes`, `edges` and `inputKeys`. There are no per-node editing tools, so every change is a read, modify, write of the whole graph through `workflow_create` or `workflow_update`. Never hand-write `flow`: `workflow_publish` compiles it from `editor_info` and flips the status to `ready`.

Before writing any graph, the skill sends you to `references/editor-info.md` for the node type vocabulary, the edge direction rule and a minimal validated example. Templates are found with `search` using `target="workflows"`, `public=true` and `limit=3`, then fetched with `workflow_get` — search hits are summaries, not graph documents. Create, update, publish, copy and delete sit in the tool catalog, while `workflows_list`, `workflow_get` and `workflow_run` are direct tools.

Watch out for `workflow_create`: it is two calls underneath, so a failed create may still have made a draft whose id appears in the error. Recover with `workflow_update` on that id, because re-creating duplicates the workflow. The other trap is wiring a batch of assets straight into a model's reference field — that is one generation over every item at once. When each item needs its own result, put the model inside a `forEach`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-workflow-authoring -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scenario-workflow-authoring/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scenario-workflow-authoring/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-workflow-authoring -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scenario-workflow-authoring/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-workflow-authoring -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scenario-workflow-authoring/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scenario-labs/skills scenario-workflow-authoring
```

2. **Manually: put the files in place**
- File: `.github/skills/scenario-workflow-authoring/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-workflow-authoring -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scenario-labs/skills --path skills/scenario-workflow-authoring
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scenario-workflow-authoring/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-workflow-authoring -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- build a Scenario app from a written brief
- add a model or approval gate node to a graph
- turn a prompt chain into a published app
- migrate a pipeline built in ComfyUI or Weavy
- import an exported workflow JSON

## Example prompts
- Build a Scenario workflow that turns text into an image and publish it
- Add a model node to this graph and validate it with dry_run
- Migrate this ComfyUI export into a Scenario graph

# Scenario Workflow Authoring

## Overview

A workflow has two representations: `editor_info` (the editable node graph: `nodes`, `edges`,
`inputKeys`) and `flow` (the compiled runnable form). Authoring through MCP means writing the whole
`editor_info` document: there are no per-node editing tools; every change is a read, modify, write
of the full graph through `workflow_create` or `workflow_update`. Never hand-write `flow`:
`workflow_publish` compiles `editor_info` into it and flips status to `ready`. Editing a ready
workflow's `editor_info` leaves the stale `flow` running until you publish again.

Read [references/editor-info.md](references/editor-info.md) before writing any graph: it holds the
node type vocabulary, the node choice doctrine (when an `llm` node is legitimate), the edge
direction rule, per-node data contracts, and a validated minimal example. Create, update, publish,
copy and delete live in the tool catalog (`scenario_tools_search` plus the matching executor, see
the `scenario` skill). `workflows_list`, `workflow_get` and `workflow_run` are direct tools: scope
and `dry_run` go in their top-level arguments, never an executor wrapper. Running and pricing: the
`scenario-workflows` skill. If a sibling skill named here is missing from your available skills, ask
the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed
from tool schemas and flag the gap.
