Resume playback

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

No annotations provided, so the description bears full burden. It only states the action without explaining behavior in edge cases (e.g., already playing, errors, prerequisites). For a 0-param tool, more context is needed.

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 a single 5-word sentence, perfectly front-loaded with no wasted words. It conveys the essential meaning efficiently.

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?

Given 0 parameters and no output schema, the description is minimally adequate. However, it lacks details on behavior when already playing, error conditions, or state requirements, which would improve completeness for a simple tool.

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?

There are 0 parameters, and schema coverage is trivially 100%. Per calibration, baseline is 4, and the description adds the purpose of the tool without repeating any schema details.

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 explicitly states it resumes paused playback, with verb 'Resume' and resource 'paused neteasecli/mpv playback'. This clearly differentiates from siblings like pause, play_song, and next_song.

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?

Usage is implied (after pausing), but no explicit guidance on when to use versus alternatives. For example, if playback is already playing, the behavior is unclear, and no contrast with play_song for starting new playback is given.

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