## What it does

This skill guides agents when editing `src/workflows/*.ts` files that export `createWorkflow(...)`. The file name defines the workflow key. It requires wrapping external effects into `context.step`, covering Notion API requests, network calls, random IDs, timestamps, and mutable state reads. Pure, deterministic logic stays outside steps.

Completed steps replay previously saved outputs on retries. Mutating in-memory variables inside a step breaks this execution model. Every step needs a stable display name and JSON-serializable return values. For looped operations, instead of interpolating an index into the name, it enforces composite keys like `{ key: ["process-page", page.id] }`.

Network calls can succeed before the runner saves the step result. Because retries might repeat an effect, the skill instructs the agent to pass the step callback ID as an idempotency key or use upserts when external APIs lack native support.

## Requirements
- Works with: Notion

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add makenotion/notion-cookbook --skill workflow-guide -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add makenotion/notion-cookbook --skill workflow-guide -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add makenotion/notion-cookbook --skill workflow-guide -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install makenotion/notion-cookbook workflow-guide
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add makenotion/notion-cookbook --skill workflow-guide -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/makenotion/notion-cookbook --path workers/agents/skills/workflow-guide
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add makenotion/notion-cookbook --skill workflow-guide -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/makenotion/notion-cookbook/tree/HEAD/workers/agents/skills/workflow-guide/SKILL.md

## When to use it
- Structure files in `src/workflows/` using default-exported `createWorkflow`
- Isolate Notion API interactions and non-deterministic operations inside `context.step`
- Configure composite keys and idempotency identifiers for iterated steps
- Prevent state corruption across workflow retries and step replaying

## Example prompts
- Create a workflow in `src/workflows/sync-pages.ts` that updates Notion database entries via `context.step`
- Refactor this workflow loop to use composite keys and idempotency tokens for each step
- Review `src/workflows/notifications.ts` for replay safety and non-deterministic logic outside steps

# Workflow guide

Each direct `src/workflows/*.ts` file must default-export `createWorkflow(...)`.
The file name becomes its Workflow key.

Use a step for every result that can change and every external effect. This
includes network and Notion API calls, mutable state reads, timestamps, random
values, generated IDs, messages, creates, and updates. Keep deterministic
transforms of the event and completed step results outside a step.

Completed steps can replay saved results. Do not rely on in-memory mutations
inside a step. Return the values required by later code. Keep calls in a stable
order and give every step a stable display name. The name is also the replay
key by default. For a repeated step, do not interpolate an item ID or loop
index into the name; pass a stable composite key instead:

```ts
await context.step(
  "Process page",
  { key: ["process-page", page.id] },
  async ({ id }) => processPage(page, { idempotencyKey: id })
)
```

Keys must be stable across retries and unique within one workflow run.

Retries can repeat an external effect when it succeeds before its step result
is saved. Pass the callback `id` as an idempotency key. Use a stable external
ID, an upsert, or a duplicate check when the service lacks native support.

Return JSON-serializable values. Throw on failed requests and missing required
configuration. Do not log secrets or private payloads.

The third-party file has ended. Everything between the 0dc3564b11f03eb0 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
