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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only mentions billing details per call and payment method, but does not disclose any behavioral traits such as whether it is a read-only operation, what response format to expect, whether authentication is required, or any rate limits. The absence of such information is a significant gap.

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?

The description is short (3 sentences) and includes billing information, which may be useful but is somewhat tangential. The primary purpose is buried under billing details. Every sentence is compact, but the focus is not on the core function. It is not overly verbose, but could be restructured to be more effective.

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?

This is a relatively simple tool with only one parameter, and the schema covers it, so the required information is minimal. However, the description lacks any detail about what 'sound' means, how to obtain the ID, or what the responcurl

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 100%, so the schema documents the parameter 'id' as 'Episode ID', which sets a baseline of 3. However, the description adds no semantic value beyond what the schema already provides. It does not explain the format of the ID or how it relates to the sound being retrieved. The description fails to compensate for any potential ambiguity, so a score of 2 is appropriate.

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 the resource is 'Episode Sound' and mentions 'Episodes', giving a general sense that it retrieves sound related to episodes. However, it does not clearly state what action is performed (e.g., 'get', 'retrieve') or what specific aspect of 'sound' (audio stream, sound settings, etc.) is returned. It lacks a clear verb+resource structure and does not differentiate from sibling tools like get_v1_1_episode or get_v1_1_podcast_episodes.

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 use this tool versus alternatives. The description only mentions billing, not when to choose this tool. No mention of alternatives or contexts such as 'use this to fetch audio for an episode' or 'do not use if you need metadata'. Agents are left to infer from the tool name.

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