Update Generic Tool Item Response

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

Annotations (readOnlyHint=false, destructiveHint=false) already indicate safe mutation. The description adds that it performs a partial update and returns the modified object. It does not mention permissions, error cases, or rate limits, but the annotations carry much of the burden.

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 somewhat verbose with redundant information (e.g., 'Update attributes' and 'Updates the specified Custom - Configurable Tools'). It includes a link, required parameter list, and endpoint path. While not overly long, it could be tighter.

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 a simple update tool with 5 parameters, no output schema, and annotations present, the description adequately explains the action, partial update behavior, and return value. It is complete enough for an AI agent to use correctly.

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?

Input schema has 100% coverage with descriptions for all 5 parameters. The description repeats the required parameters but adds no additional semantic meaning beyond the schema. 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 clearly states the verb 'Update' and the resource 'attributes on a generic tool item response'. It also specifies that only supplied fields are changed. However, it does not differentiate this tool from siblings like batch_update_generic_tool_items or create_generic_tool_item_response.

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 indicates to use this for updating an existing tool item response and lists required parameters. It mentions partial updates ('only the supplied fields are changed'). However, it provides no guidance on when not to use this tool versus alternatives, such as batch operations.

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