Guides/Abilities Marketplace

Abilities Marketplace

A curated collection of Claude Code plugins covering the full agent lifecycle — from scaffolding and onboarding to deployment, scheduling, and ongoing operations.

Concepts

•Plugin marketplace — A registry of versioned plugin packages hosted at github.com/abilityai/abilities. Claude Code's /plugin marketplace add command connects to it.

•Plugin — A named package of skills installed into your Claude Code session. Skills become available as /plugin-name:skill-name commands.

•Skill — A single SKILL.md file defining a workflow Claude executes when you invoke it.

•abilities — The specific marketplace hosted by Ability.ai, containing 5 plugins for the agent development lifecycle.

The Four-Step Agent Workflow

Scaffold            Develop                     Deploy           Iterate
/create-agent:*     /agent-dev:create-playbook  /trinity:onboard /trinity:sync
                    /agent-dev:add-memory                        git push
                    /agent-dev:add-backlog                       /create-agent:adjust

Scaffold

Pick a wizard or use /create-agent:custom. Get a fully wired agent in one session.

Develop

Add skills, memory systems, and task management as the agent's role expands.

Deploy

Run /trinity:onboard to deploy to your Trinity instance. It runs 24/7 from there.

Iterate

Push changes with git push or /trinity:sync. Use /create-agent:adjust to audit and improve over time.
