Show this account's remaining compute credits. One credit runs one standard environment for one minute; paused environments use no compute credits.

Create a persistent development environment: a filesystem and processes that survive between calls. Optionally clone a git repository into it. Returns the environment id used by every other tool.

List this account's environments, with how many forks each has.

What an environment resumes from: its head snapshot, how far its log had got, and its fork tree. Every start is a cold boot from the head snapshot: files survive, running processes do not.

Run one command in an environment and get its exit code and output. Not a shell: pass argv as a list, and ask for a shell explicitly with ["/bin/sh","-lc","…"] if you want one. A paused environment resumes to serve this.

Fork an environment from its last sealed snapshot into a new one. The original is untouched. This is how you try several approaches from one prepared state — the fork costs a delta, not a rebuild.

Archive an environment, freeing the plan slot it holds. Nothing is deleted: its snapshots and history survive, it simply stops counting as live and can no longer be used.
