Improve reasoning (dev score 83.3)
A short, task-aware reasoning protocol will reduce indexing, changing-base percentage, and ordering errors without the cost of a separate planner or review call. Calendar arithmetic should be delegated to date_calc after deriving the correct elapsed-day offset.
The visible reasoning failure is an off-by-one error in a work/rest cycle calendar problem (35th working day answered as 2028-01-15 instead of 2028-01-14). The current genome has an empty system prompt and 'direct' strategy, so the model produces the answer without showing intermediate state. Many reasoning-family items (two-warehouse percentage transfers, ordering seven people, duty cycles) fail through skipped bookkeeping, not missing knowledge. A compact, task-agnostic protocol should help: (a) work out the structure first, (b) convert counting problems to closed-form index arithmetic (for a cycle of W work days and R rest days, the n-th working day is at offset ((n-1) div W)*(W+R) + ((n-1) mod W) from the first working day), (c) use date_calc add_days rather than mental calendar math, (d) re-verify by sanity-checking the first and last items and by re-deriving with a different metho…
Lowering temperature from 0.7 to 0.0 eliminates stochastic reasoning errors and benchmark variance (which caused wide confidence intervals in Experiments #1-#3). Simultaneously enabling date_calc and text_inspect alongside calculator, upgrading memory retrieval to hybrid (topK=10), and adding a compact verification protocol in system.md for 0-indexed cycle/calendar offsets, sequential state tracking, and sequence-ordered memory resolution will directly fix calendar-cycle reasoning failures (like reasoning:05) while lifting tool_use and memory in a single high-signal, single-pass update.
Switching the reasoning strategy from 'direct' to 'plan_and_execute' and enabling a structured planner will prevent off-by-one errors in multi-step reasoning tasks (like the robot work-cycle problem) by forcing the agent to explicitly map out the sequence of events before calculating the final date.
