UnverifiedPerforming a global search on suspicious parameters to distinguish whether they are returned by the server or generated by the frontend, and prioritizing by the order of "server-issued parameters reuse directly, frontend-generated parameters need reverse engineering" can systematically reduce invalid workload67% similarUnverifiedTruncation strategies across frameworks include dropping the oldest messages, dropping the middle, preferentially dropping large tool outputs, and keeping the system prompt plus the latest N tokens, among which "dropping the middle" is the most dangerous.67% similarUnverifiedThe stripping strategy (generate first and then truncate) may corrupt already-generated content, so the mainstream approach is pre-emptive masking rather than post-hoc truncation.67% similarUnverifiedWhen a tool call is triggered three times, it could be the model retrying itself, the framework's retry policy, or the tool registry's idempotency handling—all three layers are suspects but they cannot be distinguished in the logs.64% similarUnverifiedA failed attempt returns to the queue with the verification output and goes into the next prompt; after three failures, the task goes into the inbox along with its worktree.64% similar
