jump_to_playlist_index

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

The description lacks details on the behavioral impact beyond the fact it is not read-only (as indicated by annotations). It does not specify whether playback starts, if the playlist state changes, or any side effects, leaving ambiguity.

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, clear sentence with no extraneous words. It efficiently conveys the core purpose.

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 the tool's simplicity and lack of output schema, the description should clarify the effect of jumping (e.g., whether it starts playing or just selects). It fails to provide sufficient context for an agent to fully understand the tool's behavior.

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%, with both 'playerId' and 'index' described in the schema. The description adds no additional meaning or constraints beyond what the schema already 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 clearly states the action ('jump') and the resource ('specific track index in the current playlist'). It effectively distinguishes from sibling tools like 'play_track' (which uses track ID) or 'seek' (which seeks within the current track).

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 provided on when to use this tool versus alternatives, such as 'play_track' or 'seek'. The description simply states the action without context for appropriate use.

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