1. Sign up
Create an Archal account and open Dashboard > Setup. New self-serve accounts receive 15 arrives when the first sandbox is ready to use. No card is required, and the credit does not renew.2. Copy the setup prompt
Choose Claude Code, Codex, Cursor, Windsurf, or the portable skill target. The dashboard creates a short-lived pairing prompt for that target. Paste the full prompt into your coding agent. Treat it like a temporary secret. Do not commit it, put it in an issue, or paste it into CI logs. The agent will:- exchange the pairing code for a protected Archal credential
- install exactly five verified skills in the repository
- verify access to the full environment catalog
- report readiness only after every checksum passes
3. Ask for one real test
Give the coding agent a concrete workflow. For example:4. Review what the agent returns
For a useful first run, expect:- the sandbox ID and selected environment IDs
- the sample ID and SHA-256 hash, or the validated custom state file
- readiness and expiry
- the application configuration changed to use returned provider URLs
- one provider-shaped read and mutation
- an explicit state diff
- reset or teardown confirmation
- redacted credentials
