get_track_tree

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

The annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered and the bar is lower. The description contributes content scope (what fields are included) but says nothing about ordering, nesting depth, or whether hidden/collapsed tracks are included — useful behavioral detail for a tree structure that is left out.

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 clause with zero filler, and the key content (group membership, fold, freeze) is front-loaded. It reads as a sentence fragment rather than a statement of action, which is the only structural weakness.

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?

With no parameters, an output schema present, and read-only annotations, this is a low-complexity tool that needs little prose. The description covers what the call returns, which is the main thing an agent needs; only the relationship to get_track_info is unaddressed.

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 takes no parameters, so there is nothing for the description to clarify beyond what the empty schema shows; baseline 4 applies. The description correctly avoids restating input details that do not exist.

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 names the resource precisely and enumerates the payload contents (group membership, fold and freeze state), which is more specific than a generic 'get tracks'. It lacks an explicit verb ('returns'/'lists') and does not contrast itself with the close sibling get_track_info, so an agent must infer the distinction from the 'tree' framing.

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 when-to-use or when-not-to-use guidance, and no mention of the obvious alternatives in the sibling list such as get_track_info or get_session_info. The only cue is implicit: fold and grouping data suggests it is for inspecting session structure rather than per-track detail.

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