# claude-workflow

Runs an agent through states declared in YAML, with transitions, nested sub-workflows and a dashboard on localhost:3100. Useful when you want a fixed order of steps instead of open-ended chat.

## What it does

The plugin wires an MCP server into Claude and keeps the session inside a finite state machine. You describe a workflow in YAML — states, transitions, prompts — and the engine holds the current state, checks each move and maintains a stack of nested sub-workflows up to depth 10. When a nested one finishes, control returns to its parent.

Definitions load from three tiers: bundled templates, global files under `~/.claude/workflows/` and project files under `.claude/workflows/`. They are snapshotted when a session starts, so editing YAML mid-run leaves the running session untouched. Every state change is persisted to JSON atomically, using a temp file, a rename and a lockfile. The package ships 20 workflows and 28 skills, provisioned on first run by a SessionStart hook.

A state does not have to be a prompt. Type `exec` fires a shell command, `fetch` sends an HTTP request, and the engine picks the next branch from the exit code or HTTP status on its own. For the agent to begin with a workflow at all, `~/.claude/CLAUDE.md` needs a call to `mcp__plugin_workflow_wf__start()`. Installing from the git repository is not supported: `build/` is gitignored, so a git-sourced install has no compiled MCP server to launch.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install claude-workflow@claude-community
```

## When to use it
- force a fixed sequence of steps on an agent
- declare a development process in YAML with states and transitions
- nest one workflow inside another and return to the parent on completion
- run tests from a state and branch on the exit code
- watch a session graph live in the dashboard

## Example prompts
- Start the workflow with `mcp__plugin_workflow_wf__start()` and walk me through the states
- List the available workflows with `mcp__plugin_workflow_wf__list`
- Move to the `write_code` state and show me the new prompt

A Claude Code plugin that drives agents through YAML-defined state machines. The engine tracks state, enforces guards, manages nested sub-workflow stacks, and visualizes everything in a web dashboard.

## Features

- **FSM-based state machines** — define workflows in YAML with states, transitions, and prompts
- **Stack-based sub-workflows** — states can push nested workflows (max depth 10), auto-pop on completion
- **Three-tier loading** — bundled templates < global (`~/.claude/workflows/`) < project (`.claude/workflows/`)
- **Snapshot isolation** — workflow definitions frozen at session start; hot-reloads don't affect running sessions
- **Runtime overlays** — modify workflows on the fly without touching YAML files
- **Action states** — `exec` runs shell commands, `fetch` makes HTTP requests, with auto-routing by exit code or HTTP status
- **Web dashboard** — real-time session monitoring with DAG graph visualization
- **20 bundled workflows** — complete agent lifecycle from routing to reflection, including long-running batch orchestration and a text-only `docs` route
- **28 bundled skills** — reusable knowledge modules auto-provisioned on first run
- **SessionStart hook** — auto-provisions missing skills and injects workflow context

## Quick Start

### From Community Plugins (recommended)

The plugin is listed in the [claude-plugins-community](https://github.com/anthropics/claude-plugins-community/) catalog:

```bash
/plugin marketplace add https://github.com/anthropics/claude-plugins-community
/plugin install workflow
```

### From npm

Create a `marketplace.json` and add it as a source, or install directly:

```bash
# 1. Add a marketplace with this plugin
/plugin marketplace add <marketplace-with-workflow>

# 2. Install
/plugin install workflow@<marketplace-name>
```

See [Creating a marketplace](https://code.claude.com/docs/en/plugin-marketplaces) for how to set up an npm-based marketplace with this plugin:

```json
{
  "name": "workflow",
  "source": { "source": "npm", "package": "claude-mcp-workflow" }
}
```

### Manual (for development)

```bash
git clone https://github.com/AxGord/claude-workflow.git
cd claude-workflow
npm install
npm run build
claude --plugin-dir ./
```

### Install channels

Supported marketplace sources: the **npm package** (`claude-mcp-workflow`) and a **local directory**. A marketplace entry that points at the git repository (git URL as a plugin source) is **not** supported — `build/` is gitignored, so a git-sourced install has no compiled MCP server to run. (Cloning for development works — see above — because you run `npm run build` yourself.)

## Recommended CLAUDE.md Snippet

The engine only helps when the agent actually starts a workflow. Add this to your `~/.claude/CLAUDE.md`:

```markdown
- **ALWAYS** start every conversation by calling `mcp__plugin_workflow_wf__start()` (no arguments) before doing anything else, including answering the user
  - **EXCEPTION**: If you are a sub-agent spawned by the Task tool, do NOT call `start()` without arguments — the parent agent manages the workflow session. Follow the start instructions from the parent's preamble instead
```

## Recommended Permissions

Auto-allow the workflow tools so the agent is not interrupted with a permission prompt on every transition. In `~/.claude/settings.json`:

```json
{
  "permissions": {
    "allow": [
````
