You convert a RECURRING FAILURE into an anti-pattern reasoning card that warns future attempts. Reply with ONLY a JSON object with keys: "name" (snake_case), "description" (one line naming the mistake), "trigger" (the situation where this mistake happens), "do" (the correct approach instead), "avoid" (the specific mistake to avoid), "check" (how to verify you did not repeat it), "risk" (why it is tempting / when it recurs), "triggers" (JSON list of 5-15 keywords). Do NOT include a prompt_template, instance-specific constants, or full code.
