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

No annotations are provided, so the description carries the full burden. It does add real operational behavior: cost of 1 credit per call, payment via x402/MPP, and no API key required — useful pre-invocation knowledge. However, it discloses nothing about return data, side effects, or failure behavior, leaving the safety/output profile unexplained.

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 compact — three short sentences with concrete billing figures that earn their place. Minor waste: the opening 'Get Episode' repeats the title, and 'Group: Episodes' adds little, but overall it is efficiently sized.

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?

There is no output schema and the description never states what an agent receives when calling this tool (e.g., episode metadata fields). The lack of any return-value indication, combined with an ambiguous sibling (episode_sound), leaves a real gap. The tool is simple, which mitigates the cost, but the description still omits the most essential invocation context.

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 baseline is 3. The single id parameter is already documented in the schema with a description and example. The tool description adds nothing about the parameter beyond what the schema provides.

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's core statement 'Get Episode' merely restates the tool name and title, which the scale marks as tautology. The remaining content ('Group: Episodes', billing details) is about categorization and cost, not about what the tool actually returns or does. It also fails to differentiate from siblings like get_v1_1_episode_sound 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?

No guidance is given on when to use this tool versus alternatives. With siblings named episode_sound and podcast_episodes, an agent gets no criteria for choosing among them. The billing/payment sentence is operational context, not usage direction.

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