Reinstallation

Custom agents are automatically reinstalled when you run bmad init --quick. Your personalization choices are preserved in .bmad/_cfg/custom/agents/.

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):

# From your project root
cp node_modules/bmad-method/src/modules/bmb/reference/agents/stand-alone/commit-poet.agent.yaml \
   .bmad/custom/agents/

For expert agents (folder with sidecar files):

# 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: Install and Personalize

npx bmad agent-install
# or: bmad agent-install

The installer will:

Find the copied template in .bmad/custom/agents/
Prompt for personalization (name, behavior, preferences)
Compile and install with your choices baked in
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

Place your .agent.yaml files in .bmad/custom/agents/. Use the reference agents as templates.

Key sections in an agent YAML:

metadata: name, title, icon, type
persona: role, identity, communication_style, principles
prompts: reusable prompt templates
menu: numbered menu items
install_config: personalization questions (optional, at end of file)

See the reference agents for complete examples with install_config templates and XML-style semantic tags.
