list_tracks

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds only a list of returned fields and says nothing about pagination, whether all tracks are returned or only filtered ones, or what open-world access entails.

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 short sentence with no filler, but it is a fragment that omits the verb and the filtering behavior, so its brevity comes at the cost of specification rather than in service of it.

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 output schema, two undocumented optional parameters, and no annotation beyond read-only, the description should clarify default scope and filtering. It does not, leaving the agent unable to know what a call with no arguments returns.

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 0%, so the two optional parameters (edit_id, package_name) are completely undocumented anywhere. The description never mentions either parameter or explains whether omitting both returns all tracks across all edits.

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 (release tracks) and enumerates returned fields (releases, version codes, status, rollout fraction), but it is a noun phrase with no verb and never says it 'lists' anything. An agent can infer purpose from the name list_tracks only, and nothing distinguishes it from siblings like set_track_release or list_listings.

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 statement of when to use this tool, no prerequisites, and no mention of alternatives such as set_track_release or list_listings. The agent must infer that this is the read path for tracks.

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