[8FXCEswvdK] catch_insects tool rejects valid N with misleading 'N must be positive' error

[flexus-teams]

Problem Summary:\nThe catch_insects tool returned "Error: N must be positive" even when called with positive values of N that were less than or equal to the remaining tongue_capacity. This caused the assistant to make extra calls and batch the requests, and produced confusing error messages in the conversation.\n\nEvidence:\n- Thread id: 8FXCEswvdK (feedback dir: feedback/kL3FL6ixCS)\n- messages.json shows multiple catch_insects tool calls and responses:\n - call_55474874: catch_insects({"N":4}) -> tool: "Error: N must be positive. Capacity: 4/4 left." (message index ftm_num=7)\n - call_21303140: catch_insects({"N":3}) -> tool: "Error: N must be positive. Capacity: 3/4 left." (message index ftm_num=11)\n - call_90446100: catch_insects({"N":2}) -> tool: "Error: N must be positive. Capacity: 3/4 left." (message index ftm_num=13)\n - Later calls of N=1 succeed: tool returns "Insect!" (ftm_num=9,15,16,17)\n- thread.json shows catch_insects is defined to require integer N and is limited by tongue_capacity (4).\n\nRoot cause (hypothesis):\nThe tool validation appears to compute an incorrect 'remaining capacity' or incorrectly validate N relative to capacity. The error message "N must be positive" is misleading: the provided N values are positive, but the tool likely checks for N > capacity_remaining or uses wrong sign/threshold logic and maps that failure to the wrong error text. Specific suspicious behavior:\n - The first call with N=4 was rejected while Capacity: 4/4 left. That suggests the code may be checking strictly N < capacity_remaining instead of N <= capacity_remaining, or it may be using a sign-inverted comparison (e.g., capacity_remaining - N < 0 but reversed).\n - Later a call with N=3 was rejected while Capacity: 3/4 left — inconsistent state reporting indicates capacity tracking may be wrong (reporting 3/4 left when it should be 4-1=3 after one success, but was earlier rejected).\n\nNext steps / Recommended fix:\n1) Inspect the catch_insects implementation, particularly input validation around N and remaining capacity. Look for off-by-one errors or inverted comparisons and correct the error text to accurately reflect the cause (e.g., "N exceeds remaining capacity" or "N must be between 1 and ").\n2) Add unit tests for boundary cases: N=capacity, N=capacity+1, N=0, N=-1, and sequential calls that fill capacity. 3) Update the tool's error messages to be descriptive and include current capacity values when rejecting a call.\n\nPlease assign to the tool-owner for investigation and add tests to prevent regressions.
