A sandbox fits any agent that should act with money without being trusted
with a key. The pattern is the same each time: fund only what the job needs,
turn on only the programs the job uses, and cap how fast it can spend.

The examples below describe the shape of the rules. Which programs you can
turn on depends on what the registry supports during the alpha; the rules
builder lists them.

## A trading agent

An agent that trades tokens on one venue from a research loop.

- **Fund:** the amount you are willing to see traded, and lost.
- **Programs:** the venue's program, with only its buy and sell instructions.
- **Spend limit:** a daily limit on that program, so a bad loop can only
  spend so much before you notice.
- **Allowlist:** empty. Proceeds stay in the sandbox or come back to you.
- **Grant:** `invoke`. Swaps are `invoke` too: the venue's own instructions,
  or a Jupiter route's (see [Swaps](/sandboxes/actions/#swaps)).

Exits stay allowed whatever the limits: the agent can always sell what it
bought.

## Dollar-cost averaging

An agent that buys a fixed amount of a token on a schedule.

- **Programs:** one swap venue.
- **Spend limit:** the size of one buy per window, so a scheduler bug can't
  buy twice in the same window.
- **Grant:** `invoke` only.

## Research and monitoring

An agent that only watches: positions, prices and activity on the programs you
care about.

- **Fund:** nothing, or a token amount.
- **Grant:** no actions. The agent uses the read side only: the sandbox's
  holdings and history, and [program reads and live views](/sandboxes/read-scope/)
  for the programs in its rules.

## Wind down

Any of the agents above can be told to exit. Grant `withdraw` and the agent
can send SOL back to your wallet, the only destination a withdraw can have.
Revoke the grant and it stops at its next call.
