spotify_podcasts_episode

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

With no annotations, the description does well by disclosing data source (Pathfinder), fallback mechanisms (episode page, embed, oEmbed), and that metadata is public. It is implicitly read-only. No contradictions.

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?

Three sentences, front-loaded with the core purpose, no fluff. Every sentence adds value.

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 simple tool, it covers purpose, parameters, and fallbacks. However, it does not describe the returned metadata fields or handling of invalid inputs, which could be helpful given no output schema.

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 coverage is 100%, but the description adds context: optionality, exclusivity (either uri or id), and default behavior. This goes beyond the schema's field descriptions.

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 clearly states it retrieves Spotify podcast episode details, specifies the data source (Pathfinder) and fallbacks, and the name matches. It is distinct from sibling tools like search or show listing.

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?

It tells how to use parameters (uri or id) and mentions default behavior, but does not contrast with alternatives like spotify_episodes_search or spotify_podcasts_show_episodes, nor when not to use it.

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