What
The startup message a session sends can now carry a worker generation number, taken from CLAUDE_CODE_WORKER_EPOCH, which changes each time the session's cloud worker restarts. A claude --cloud client that has already acknowledged one generation re-registers its device hooks and tool announcements only when the number differs.
Details
Optional field; emitted only on workers where the remote-tools gate tengu_violin_wood is on, and that gate falls back to off when no server value is present.
Evidence
CLAUDE_CODE_WORKER_EPOCH
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added sinceA small documentation edit on Environment variables touched a line naming --cloud after this was published.| `CCR_FORCE_BUNDLE` | Set to `1` to force [`claude --cloud`](/docs/en/claude-code-on-the-web#send-local-repositories-without-github) to bundle and upload your local repository instead of cloning from its remote |env-varssee the edit
Confirmed sinceAnthropic's documentation has since written up --cloud, on Use Claude Code on the web.`--cloud` works with a single repository at a time. The task runs in the cloud while you continue working locally. The older `--remote` spelling still works as a deprecated alias for `--cloud`.claude-code-on-the-websee the edit
What has happened since
Flag reading movedThe flag server now returns off for tengu_violin_wood, read as this account.A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
