A small CLI for checking nested tool calls, streaming, and the next turn
I'm the author of toolcall-check, a small Python CLI for checking chat completions compatible endpoints. It exercises two forced function calls, two streamed calls, and one two turn round trip that returns a local result and checks the exact normal answer. Nested argument values retain JSON types, and failures keep sanitized traces in a private HTML report. The included demo runs against a synthetic local fixture through the actual HTTP path, so it demonstrates report behavior rather than compatibility with a real model.
CompatCanary already covers a broad compatibility scan with forced calls, streaming, and structured output. I focused this tool on nested argument integrity, streamed fragment reconstruction, the return trip, and evidence. I have not tested against remote models yet. Feedback on the fixed probes and strict \[DONE\] requirement would be useful.
