set_multiple_annotations

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

With no annotations to rely on, the description bears full responsibility for behavioral disclosure. It only says 'parallelly,' which is vague and does not mention whether annotations are created or updated, how failures are handled, or the relationship between the parent nodeId and per-annotation nodeId. This is insufficient for a mutation tool.

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 a single sentence with no filler, front-loading the verb and object. It is concise and direct, though 'parallelly' is slightly awkward and the brevity leaves out useful detail. Still, it earns high marks for efficiency.

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 the complexity of the nested annotations array and lack of output schema or annotations, the description is too minimal. It fails to explain key behaviors like whether annotationId indicates update mode, what properties are for, or how errors are returned. The schema helps but does not compensate for the missing contextual guidance.

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 schema has 100% coverage with detailed parameter descriptions, so the description does not need to add much. However, it adds nothing beyond the schema—no examples, no clarification of the nested annotation structure, or hints about required fields. Baseline 3 is appropriate.

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 uses a clear verb ('Set') and specific resource ('multiple annotations') with a location ('in a node'), effectively conveying the batch operation. However, it does not explicitly distinguish itself from the sibling tool 'set_annotation', relying on the word 'multiple' as the differentiator.

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 no guidance on when to use this tool versus alternatives like 'set_annotation'. It does not mention scenarios such as updating existing annotations, creating new ones, or when parallelism is beneficial, leaving usage context entirely implied.

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