Write Rust code so its intent is clear at a glance and responsibilities are placed correctly. Apply this checklist: - Remove redundant comments when the code is already self-explanatory. - Keep functions/logic in the module that owns the responsibility (avoid “leaking” unrelated behavior into unrelated files). - Reduce duplicated branching: collapse overlapping `if edit && fork` / `else if` shapes into a single flow that reuses the right helper methods. - Refactor hard-to-read expressions by introducing well-named intermediate variables. - Replace “magic numbers” with named constants and prefer shared utilities over local re-implementations. Example pattern for readability (intermediate variables + simplified conditions): ```rust let requested_budget = thinking_budget_tokens(model_config); let max_thinking_budget = max_tokens.saturating_sub(MIN_ANSWER_TOKENS); let budget_tokens = requested_budget.min(max_thinking_budget); if budget_tokens >= MIN_THINKING_BUDGET_TOKENS { // build the thinking config using budget_tokens } ```
