# Custom Agent Installation
BMAD agents and workflows are now installed through the main CLI installer using a `custom.yaml` configuration file or by having an installer file.
## Quick Start
Create a `custom.yaml` file in the root of your agent/workflow folder:
```yaml
code: my-custom-agent
name: 'My Custom Agent'
default_selected: true
```
Then run the BMAD installer from your project directory:
```bash
npx bmad-method install
```
Or if you have bmad-cli installed globally:
```bash
bmad install
```
## Installation Methods
### Method 1: Stand-alone Folder with custom.yaml
Place your agent or workflow in a folder with a `custom.yaml` file at the root:
```
my-agent/
├── custom.yaml # Required configuration file
├── my-agent.agent.yaml
└── sidecar/ # Optional
└── instructions.md
```
### Method 2: Installer File
For more complex installations, include an `installer.js` or `installer.yaml` file in your agent/workflow folder:
```
my-workflow/
├── workflow.md
└── installer.yaml # Custom installation logic
```
## What It Does
1. **Discovers** available agents and workflows from folders with `custom.yaml`
2. **Installs** to your project's `.bmad/custom/` directory
3. **Creates** IDE commands for all your configured IDEs (Claude Code, Codex, Cursor, etc.)
4. **Registers** the agent/workflow in the BMAD system
## Example custom.yaml
```yaml
code: my-custom-agent
name: 'My Custom Agent'
default_selected: true
```
## Installing Reference Agents
The BMAD source includes example agents you can install. **You must copy them to your project first.**
### Step 1: Copy the Agent Template
**For simple agents** (single file):
```bash
# From your project root
mkdir -p .bmad/custom/agents/my-agent
cp node_modules/bmad-method/src/modules/bmb/reference/agents/stand-alone/commit-poet.agent.yaml \
.bmad/custom/agents/my-agent/
```
**For expert agents** (folder with sidecar files):
```bash
# Copy the entire folder
cp -r node_modules/bmad-method/src/modules/bmb/reference/agents/agent-with-memory/journal-keeper \
.bmad/custom/agents/
```
### Step 2: Create custom.yaml
```bash
# In the agent folder, create custom.yaml
cat > .bmad/custom/agents/my-agent/custom.yaml << EOF
code: my-agent
name: "My Custom Agent"
default_selected: true
EOF
```
### Step 3: Install
```bash
npx bmad-method install
# or: bmad install (if BMAD installed locally)
```
The installer will:
1. Find the agent with its `custom.yaml`
2. Install it to the appropriate location
3. Create IDE commands for immediate use
### Available Reference Agents
**Simple (standalone file):**
- `commit-poet.agent.yaml` - Commit message artisan with style preferences
**Expert (folder with sidecar):**
- `journal-keeper/` - Personal journal companion with memory and pattern recognition
Find these in the BMAD source:
```
src/modules/bmb/reference/agents/
├── stand-alone/
│ └── commit-poet.agent.yaml
└── agent-with-memory/
└── journal-keeper/
├── journal-keeper.agent.yaml
└── journal-keeper-sidecar/
```
## Creating Your Own
Use the BMB agent builder to craft your agents. Once ready to use, place your `.agent.yaml` files or folders with `custom.yaml` in `.bmad/custom/agents/` or `.bmad/custom/workflows/`.
