Code Review
This pull request prevents bare backend names, such as 'cargo' or 'gem', from being incorrectly identified as implicit tools. The logic in BackendArg and install_state.rs was updated to use split_once(':'), ensuring that a backend type is only recognized when a colon separator is present. New E2E and unit tests were added to verify these changes. I have no feedback to provide.
Greptile SummaryThis PR fixes a long-standing implicit-resolution bug where bare backend names like
Confidence Score: 5/5The change is safe to merge — it narrows an over-eager implicit resolution and is well-guarded by both unit and e2e tests. The logic change is minimal and symmetric across both call sites, directly mirroring the existing BackendType::guess contract. Existing installed tools whose stored full value already contains a colon are unaffected; only bare names that should never have matched now correctly fall through to BackendType::Unknown. No files require special attention — the changed surface is small and the new tests cover the critical paths.
