id: 29 title: Auto-Approve Empty-Array Tool Invocations status: Not started # one of: Not started, Started, Needs manual review, Done, Cancelled summary: Automatically approve tool-use requests where the command array is empty, bypassing the approval prompt. goal: | In rare cases the model may emit a tool invocation event with an empty command: []. These invocations cannot succeed and continually trigger errors. Automatically treat empty-array tool requests as approved (once), suppressing the approval UI, to allow downstream error handling rather than perpetual prompts. ## Acceptance Criteria - Detect tool requests where command: [] (no arguments). - Do not open the approval prompt for these cases; instead, automatically approve and allow the tool pipeline to proceed (and eventually handle the error). - Include a unit test simulating an empty-array tool invocation that verifies no approval prompt is shown and that a ReviewDecision::Approved is returned immediately. ## Implementation How it was implemented
- In the command-review widget setup (ApprovalRequest::Exec), check for command.is_empty() before rendering; if empty, directly send ReviewDecision::Approved and mark the widget done. - Add a Rust unit test for UserApprovalWidget to feed an Exec { command: vec![] } request and assert automatic approval without rendering the select mode. ## Notes - This is a pragmatic workaround for spurious empty‑command tool calls; a more robust model‑side fix may replace this later.
