set_bookmark_options

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

No annotations are provided, so the description carries full responsibility. It explains what each flag does (suppressData turns DATA off, etc.), clarifies the partial update behavior ('Only the supplied options change'), and defines targetVisuals semantics. It does not discuss error handling or return values, which is a minor gap.

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 three sentences long, front-loads the main purpose, and every sentence adds necessary detail. There is no fluff or redundancy.

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 no output schema and no annotations, the description covers all key parameters and the partial-update behavior. It omits context on reportSessionId and return values, but for a setter tool it is largely self-contained and understandable.

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 coverage is 83%, so the baseline is 3. The description adds meaningful conceptual mappings beyond the schema, such as linking suppressData to DATA and explaining targetVisuals as a JSON array. This deepens understanding, though reportSessionId remains unclear.

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 starts with a specific verb and resource ('Set a bookmark's OPTIONS') and clearly enumerates the Data/Display/Current-page/Selected-visuals toggles. It distinguishes itself from sibling tools by focusing solely on bookmark options, avoiding confusion with set_bookmark_data_state or update_bookmark.

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?

The description provides context about what the tool does but never explicitly states when to use it versus alternatives like set_bookmark_data_state or update_bookmark. Usage is implied through the option names, yet no exclusions or alternative references are given.

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