get_playlist

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

With no annotations supplied, the description carries the full behavioral burden and does not meet it. It implies a read via 'Get', but says nothing about required permissions, behavior when an ID does not exist, or whether 'entries' means full track objects or summaries.

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?

A single front-loaded sentence with no filler, which is well-sized for a simple two-parameter read tool. It loses a point only because the trailing 'including its entries' clause is vague rather than informative.

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 read tool with no output schema and no annotations, the description is minimally viable: it tells the agent what comes back in broad terms. But it leaves unresolved whether 'entries' duplicates get_playlist_tracks and gives no error or permission context.

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 100%, so station_id and playlist_id are already documented in the schema; the description adds no format, range, or sourcing detail. Baseline 3 is appropriate when the schema does the heavy lifting.

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 clear verb ('Get') and resource ('playlist'), and the word 'single' plus the plural sibling get_playlists distinguishes it from list-style retrieval. However, 'including its entries' overlaps ambiguously with the sibling get_playlist_tracks, so the boundary is not fully drawn.

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?

There is no explicit when-to-use guidance, no prerequisites, and no mention of alternatives such as get_playlists or get_playlist_tracks. The agent must infer from the name alone that this fetches one playlist by ID.

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