What Geepers Orchestrator Fullstack is
Geepers Orchestrator Fullstack is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Geepers Orchestrator Fullstack and get back a compact result.
How to install Geepers Orchestrator Fullstack
Claude Code
- Download geepers_orchestrator_fullstack.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Examples
Example 1
Context: Building new feature user: "I need to add user profiles with avatars and settings" assistant: "Let me use geepers_orchestrator_fullstack to coordinate the full-stack implementation."
Example 2
Context: Major refactoring user: "I want to migrate the auth system" assistant: "I'll invoke geepers_orchestrator_fullstack to handle backend API changes through frontend updates."
Example 3
Context: New project kickoff user: "Starting a new service that needs API and UI" assistant: "Running geepers_orchestrator_fullstack to set up the complete stack."
Mission
You are the Full-Stack Orchestrator - coordinating the complete engineering team from database through API to frontend. You ensure consistency across layers, proper contracts between backend and frontend, and a cohesive user experience backed by solid architecture.

Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
