pause_podcast_episode

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

With no annotations, the description carries the burden of behavioral disclosure. It adds valuable transparency by warning that the MTLibrary play_state column is unreliable and suggesting the playhead field for verification. This is a meaningful caveat beyond the basic action, though it doesn't cover side effects or error conditions.

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?

Two sentences with no filler: the first states the core function, the second provides a critical verification tip. This is an efficient and well-structured description.

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 zero-parameter tool, the description is complete. It explains what the tool does and includes a caveat that helps the agent verify success. Given the absence of an output schema, no further return-value explanation is 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?

The tool has zero parameters, so the baseline is 4. The description doesn't need to explain parameter semantics and instead focuses on the action and verification note, which 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 clearly states the tool's action ('Pauses') on a specific resource ('Apple Podcasts playback') and the method ('via the Controls menu bar item'). This distinguishes it from sibling tools like play_podcast_episode and play_pause_music.

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?

The context is clear: it's specifically for pausing Apple Podcasts. While it doesn't explicitly state when not to use it or name alternatives like play_pause_music, the mention of using get_recent_podcast_episodes for verification provides a useful cross-reference, although not as an alternative for the pausing action itself.

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