# Crews overview

A crew is a small organization: one lead agent orchestrating a team of agents, each with a role, all working toward a mission. Pick a crew in the composer and the lead plans the work, delegates to the right teammate, and integrates the results.

## What a crew is

A single agent is one specialist with one brain. A crew is a team of them with a chain of command. It has four parts:

- A lead — the supervising agent. It orchestrates: it plans, hands scoped work to the right teammate, and stitches the pieces back together. It never tries to do everything alone.
- A team — the other agents in the lineup. Each is a full agent with its own skills and tools, and each gets a role in this crew (Engineer, Reviewer, Researcher…).
- A mission and goal — why the crew exists, and the objective the lead drives the team toward. Both are woven into the lead’s brief.
- A tier — the gateway pool every member runs at. One knob shifts the whole crew between Fast, Premium, and Max.

## Tiers, not models

A crew runs at one of three tiers — Fast, Premium, or Max. The tier isn’t a model name; it’s a gateway pool. Each member resolves its own model from its role times the crew’s tier, through the gateway. Move the tier up and every seat upgrades together — you never pin a model yourself.

- Fast — quick answers and everyday tasks; the lead’s edge is routing and momentum.
- Premium — serious build work, premium models per role.
- Max — the hardest problems, frontier models at every seat.

> Built-in tier crewsFoxora ships three built-in crews — Fast, Pro, and Max — that pair the full specialist lineup with a tier and a tuned orchestration style. They’re a great default before you build your own.

## A crew vs. a single agent

Reach for a crew when the work has more than one shape:

- Use a single agent when the task is one specialty end to end — a focused edit, a piece of research, one document.
- Use a crew when a job spans specialties or splits into parallel parts — plan and build and review a feature; research, draft, then fact-check. The lead breaks it down and runs the team.

Because each teammate is a real agent, a crew’s capabilities are just its members’ capabilities. To change what a crew can do, edit its agents — their skills and connections carry through.
