Each tool clearly targets a distinct operation: transcribe_start creates a job, transcribe_status queries one job, transcribe_list lists all recent jobs, and check_setup validates the environment. There is no overlap or ambiguity in purpose.

All tool names use consistent snake_case with a predictable verb_noun structure (transcribe_list, transcribe_start, transcribe_status, check_setup). The shared transcribe_ prefix for core operations and distinct check_setup for setup are logically organized.

Four tools is well-scoped for a focused background transcription service: one for environment check, one to start jobs, one to list jobs, and one to check status. No unnecessary tools and no obvious thinness for the core workflow.

The core lifecycle (setup check, start job, list jobs, poll status) is fully covered. Minor gaps exist, such as cancelling/deleting jobs or directly retrieving subtitle content via MCP, but agents can work around these by using returned file paths.
