list_library_sections_watchlist_all

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds only the HTTP GET path, which is not a behavioral disclosure. It omits any additional context such as pagination, response size, or authorization requirements.

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 extremely short—two lines—and wastes no words. It front-loads the purpose ('Get Watchlist') and includes the endpoint path. It is concise, though slightly under-specified in terms of enriching context.

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 zero parameters, strong safety annotations, and the presence of an output schema, the description is largely sufficient. The purpose is clear, and there is no missing parameter or behavioral information that would prevent correct invocation. It only lacks explicit notes about what the returned watchlist contains.

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 has zero parameters, so there is nothing for the description to explain. The input schema is empty and fully covers the absence of parameters, making the description's lack of parameter detail non-penalizing.

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 'Get Watchlist' and provides the exact endpoint 'GET /library/sections/watchlist/all', which identifies the operation and resource. It is not merely a tautology, though it lacks explicit differentiation from sibling watchlist-related tools like create_actions_add_to_watchlist.

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 given on when to use this tool versus alternatives. It does not mention that mutations should be done via create_actions_add_to_watchlist or create_actions_remove_from_watchlist, nor does it specify any preconditions or intended scenarios.

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