Claude ran destructive `docker compose down --remove-orphans` when asked only to "close and reload" (restart)

Summary

I asked Claude Code (Opus 5, desktop app) to "completly close and reload lab docker instances and its predeccessors" — i.e. restart my local Docker lab stack. Instead of a restart, Claude ran docker compose down --remove-orphans, which removed the containers — destroying their logs and any non-volume container data — and it did this to my stopped astro-spa / fotovmag-astro-spa containers too, which I never asked it to touch.

I never wrote the words delete, remove, down, or -v. "Close and reload" is a restart, not a teardown.

It then told me "every container you had still exists" when it had no basis for that: the pre-restart docker ps had hung, so the only container list it ever saw was taken after the destructive step.

My exact prompt

completly close and reload lab docker instances and its predeccessors

What Claude did, in order

1. docker desktop stop (hung), then force-killed Docker Desktop / com.docker.backend / com.docker.build, then wsl --shutdown.
2. Relaunched Docker Desktop, waited ~55s for the engine.
3. docker compose --profile astro --profile setup --profile cli down --remove-orphans -t 20 ← the destructive step. compose down removes containers. A restart must never do this.
4. docker compose up -d (which does not start --profile astro services, so my astro containers stayed gone until step 5).
5. Only later recreated astro-spa / fotovmag-astro-spa.

Claude's own reasoning at the time

• It read "close" as docker compose down (remove) rather than stop / restart (preserve).
• After the fact it asserted volumes were safe and "every container you had still exists" — but the only docker ps it ever saw was post-down, so that reassurance was unfounded.

Why this is a problem

• "Reload / restart" is not "remove." A restart must use docker restart or stop + start, which preserve the container, its logs, and its writable layer. docker compose down destroys all of that.
• Container logs and non-volume data were lost (e.g. Mailpit has no volume → its captured inbox is gone). Not recoverable.
• It acted outside the scope of the request (--remove-orphans, plus the stopped astro containers I never mentioned).
• It then stated a reassuring falsehood ("everything still exists") with no evidence.

Request

Destructive Docker operations — compose down, down -v, rm, --remove-orphans — should require explicit confirmation and must never be substituted for a "restart / reload" request. An assistant that destroys user data outside the literal scope of an instruction, and then misreports the result, is a serious safety issue — including under EU consumer-protection / GDPR expectations.
