create_podcasts_by_id_match_episodes

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

Annotations already cover idempotency, read-only, and destructive hints, so the description doesn't need to restate them. The description adds the 'override' behavior (override existing details if set to 1), which is a meaningful behavioral disclosure. It also characterizes the operation as 'quick match,' but this is vague. Overall, it adds some value beyond annotations but lacks richer details like side effects or authorization requirements.

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 exceptionally concise: a one-line summary, the HTTP endpoint, and three clearly labeled arguments. It front-loads the core purpose and avoids any fluff or repetition. Every sentence earns its place, making it easy to scan.

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?

For a tool with a simple parameter set and an output schema, the description is mostly sufficient, but the body parameter is a significant gap. The agent is told to 'read the matching GET or the /schema endpoint first' without specifying which GET or what fields to expect. This is an external dependency that may not be accessible to the agent. Annotations provide safety context, but the ambiguity around the payload prevents full completeness.

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%, so the description is the sole explanatory source. It does provide semantics for each parameter: id as a path parameter, body as a payload with a pointer to the matching GET or /schema endpoint, and override as 'override existing details if set to 1.' This adds meaning beyond the bare schema, but the body description is not self-contained—it defers to external endpoints rather than summarizing expected fields.

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 action ('match') and resource ('podcast episodes'), which clearly differentiates it from siblings like create_items_by_id_match (which targets items). However, 'Quick match' is somewhat vague—it doesn't explain what matching entails or whether it creates associations or metadata. Still, the verb+resource is identifiable and distinguishes from most siblings.

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. There is no mention of conditions, exclusions, or comparisons to related tools like create_items_by_id_match or get_podcasts_by_id_search_episode. The only contextual hint is to read the matching GET or /schema endpoint for body fields, which is about parameter usage, not tool selection.

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