Slime Code Review Preferences

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.
