 - [ ] `pnpm run build` (last sanity check after tests)
 - [ ] `pnpm release:check` (verifies npm pack contents)
 - [ ] `pnpm test:install:smoke` (Docker install smoke test; required before release)
+  - If the immediate previous npm release is known broken, set `CLAWDBOT_INSTALL_SMOKE_PREVIOUS=<last-good-version>` or `CLAWDBOT_INSTALL_SMOKE_SKIP_PREVIOUS=1` for the preinstall step.
 - [ ] (Optional) Installer E2E (Docker, runs `curl -fsSL https://clawd.bot/install.sh | bash`, onboards, then runs real tool calls):
   - `pnpm test:install:e2e:openai` (requires `OPENAI_API_KEY`)
   - `pnpm test:install:e2e:anthropic` (requires `ANTHROPIC_API_KEY`)
