The two tools have clearly distinct purposes: one lists voice references (a read-only operation), and the other generates speech (a synthesis operation). There is no overlap or ambiguity between these functions, making it easy for an agent to select the correct tool.

Both tools follow a consistent snake_case naming pattern with a 'fish_audio_' prefix, followed by a descriptive verb_noun combination (list_references and tts). This uniformity enhances readability and predictability across the tool set.

With only two tools, the server feels under-scoped for a TTS API domain. Key operations like managing references (e.g., create, update, delete) or configuring TTS parameters are missing, limiting the server's utility and forcing agents to work around gaps.

The tool set is severely incomplete for a TTS API. While it covers listing references and generating speech, it lacks essential CRUD operations for references (e.g., create, update, delete) and configuration tools (e.g., set parameters, list voices). This will likely cause agent failures in common workflows.
