Slime Code Review Preferences
Apply these lightweight review heuristics when changing slime code.
Prefer Direct APIs Over Thin Wrappers
- Remove helper layers that only rename a call, format one path, or forward arguments without owning meaningful behavior.
- Prefer calling the concrete reusable API directly, for example a
*_to_path helper when the caller already knows the destination path.
- Keep a wrapper only if it owns a real boundary: compatibility, validation, nontrivial error policy, lifecycle management, metrics/logging semantics, async/retry behavior, or cross-module ownership.
- Avoid moving a redundant wrapper's body into another file just to preserve the wrapper shape. Inline the simple call at the natural ownership site.
- When removing a wrapper, search for sibling wrappers and nearby helpers with
rg and delete confirmed dead functions in the same pass.
- Treat single-use convenience functions as suspicious when their only job is path formatting plus forwarding. Prefer the caller owning that one line.
Make Branches Explain Themselves
- Order conditionals by semantic precedence: special transport/lifecycle modes first, then explicit mode choices, then default paths.
- Prefer predicates that fully describe the branch, such as
mode == "full" and transport == "disk", over a broad predicate followed by an assert that explains what the branch really meant.
- Use asserts as invariants for impossible states after validation, not as a substitute for clear branch conditions.
Keep Abstractions Honest
- Add an abstraction only when it removes real duplication, hides fragile mechanics, or clarifies ownership.
- When a review comment points out repeated indirection, look for a smaller public surface rather than adding another alias.
- Preserve existing behavior intentionally. If cleanup changes error handling, logging, or failure visibility, call that out in the final response.
