list_me_bookmarks

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

The description adds no behavioral information beyond the annotations. Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, and the description merely repeats the HTTP GET method. It does not add context like whether all bookmarks are returned, pagination, or authentication 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 concise: one short sentence and an endpoint line. It front-loads the core meaning and contains no filler or redundant phrasing.

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-only tool with no parameters, an output schema, and full annotation coverage, the description is nearly adequate. However, it leaves the meaning of 'me' slightly implicit and does not clarify that this lists the current user's bookmarks in contrast to the per-item sibling, so a small completeness gap remains.

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 clarify. Baseline 4 applies because parameter semantics are moot when no parameters 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 'Get me bookmarks' clearly identifies the verb (get) and resource (bookmarks) scoped to the current user, and the endpoint reinforces it. It does not explicitly distinguish from the sibling get_me_bookmarks_by_library_item_id, but the list prefix and simple wording make the general intent clear.

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 get_me_bookmarks_by_library_item_id. There is no mention of context, prerequisites, or conditions that would steer an agent toward or away from this tool.

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