get_track_num_sends

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears the full burden. It implies a read-only accessor but says nothing about error behavior for an invalid track_index, whether the count includes disabled/inactive sends, or what format the number takes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no waste. It is efficient, though its brevity is achieved partly by omitting information that would be useful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations, no output schema, and an undocumented parameter, the description leaves key gaps: it does not explain the track_index, the semantics of the returned count, or failure modes. For a tool this terse, more was needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the single required parameter track_index is undocumented in both schema and description. The description does not clarify whether the index is zero-based, refers to the track list position, or must correspond to an existing track.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Get') and resource ('number of sends from a track'), so an agent knows it is a read accessor for send count. It is not tautological, but it does not distinguish itself from near siblings like get_track_count or create_send/delete_send beyond the obvious noun 'sends'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to call this rather than the related send tools (create_send, delete_send, set_send_volume) or how the returned count relates to them. Usage is only implied by the verb 'Get'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
