## Summary - When `langgraph deploy` prompts for the deployment name interactively, persist it as `LANGSMITH_DEPLOYMENT_NAME` in the `.env` file so subsequent deploys pick it up automatically - Extracted `_resolve_env_path()` helper from `_parse_env_from_config()` to share env file path resolution logic - Skips writing when env vars are configured as an inline dict in `langgraph.json` (no file to write to) - **CI fix**: CLI integration tests were using `pip install` but `setup-uv` with caching enabled, so the post-step cache save failed on a non-existent directory — switched to `uv pip install` ## Test plan - [x] All 207 existing unit tests pass - [ ] Manual: run `langgraph deploy` without `--name`, enter a name at prompt, verify `.env` now contains `LANGSMITH_DEPLOYMENT_NAME=<name>` - [ ] Manual: run `langgraph deploy` again, verify the name is picked up from `.env` without re-prompting - [x] CI integration test cache fix (broken on main since Feb 2026)
