v0.3.13 switched ENTRYPOINT to ["webclaw"] to make `docker run IMAGE https://example.com` work. That broke a different use case: downstream Dockerfiles that `FROM ghcr.io/0xmassi/webclaw` and set their own CMD ["./setup.sh"] — the child's ./setup.sh becomes arg to webclaw, which tries to fetch it as a URL and fails: fetch error: request failed: error sending request for uri (https://./setup.sh): client error (Connect) Both Dockerfile and Dockerfile.ci now use docker-entrypoint.sh which: - forwards flags (-*) and URLs (http://, https://) to `webclaw` - exec's anything else directly Test matrix (all pass locally): docker run IMAGE https://example.com → webclaw scrape ok docker run IMAGE --help → webclaw --help ok docker run IMAGE → default CMD, --help docker run IMAGE bash → bash runs FROM IMAGE + CMD ["./setup.sh"] → setup.sh runs, webclaw available Default CMD is ["webclaw", "--help"] so bare `docker run IMAGE` still prints help.
