create

A command for creating or selecting a Sprites.dev cloud sandbox, which is a remote computer environment for running code.

In plain words
What is it for?
Use it to list existing sandboxes, create a new one, or select one for the current project.
Why use it?
It gives a project an active remote environment where later commands can run code away from the local machine.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Create or Select a Sprite

Create a new Sprites.dev cloud sandbox or select an existing one as the active sprite for this project.

Behavior

If a sprite name is provided:

  1. Check if sprite exists with sprite list
  2. If it exists, set it as active with sprite use <name>
  3. If it doesn't exist, create it with sprite create <name> then set as active

If no sprite name is provided:

  1. List existing sprites with sprite list
  2. Show the list to the user
  3. Ask if they want to use an existing sprite or create a new one

Commands to Use

# List sprites
sprite list

# Create new sprite
sprite create <name>

# Set active sprite for current directory
sprite use <name>

# Check current active sprite
sprite use

Output

After completing, report:

  • Sprite name
  • Whether it was created or already existed
  • Confirm it's set as active

Tips

  • Sprite names should be lowercase, alphanumeric with hyphens
  • Sprites auto-hibernate after 30 seconds of inactivity (no cost when idle)
  • Sprites have persistent filesystems - data survives hibernation
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
