The Agent Development Workflow

Abilities supports a four-step workflow:

1. Scaffold              2. Develop                    3. Deploy              4. Iterate
/create-agent:*          /agent-dev:create-playbook    /trinity:onboard       /trinity:sync
                         /agent-dev:add-memory         trinity deploy .       git push
                         /agent-dev:add-backlog                               /create-agent:adjust
1.Scaffold - Use a wizard like /create-agent:prospector or /create-agent:custom to get a fully configured agent
2.Develop - Use /agent-dev:create-playbook to add capabilities, /agent-dev:add-memory for persistence
3.Deploy - Run /trinity:connect once to authenticate, then /trinity:onboard per agent
4.Iterate - Push changes with git push or /trinity:sync. Use /create-agent:adjust to audit

What Wizard-Created Agents Include

Every agent created with the wizards includes:

CLAUDE.md - Identity and behavioral instructions
Initial skills - 2-4 playbooks based on agent purpose
Onboarding system - onboarding.json + /onboarding skill
