Retrieve input schema

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, fully covering the safety profile. The description's only behavioral claim ("Read operation") merely echoes readOnlyHint, adding no new context such as auth/account coupling or scoping behavior.

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?

It is short and front-loaded, but the second line "Read operation" is pure redundancy with the annotations and earns no place. Brevity here reflects under-specification rather than 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?

For a 4-parameter tool (with required saved_item_id and an account/user/project identity choice) and no output schema, the description says nothing about what an 'input schema' contains or how the identity parameters interact. It is too thin to guide correct invocation.

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 description coverage is 100%, so all four parameters (account, user_id, project_id, saved_item_id) are documented in the schema itself, including the user_id/project_id mutual requirement. The description adds nothing, but the baseline is 3 when the schema carries the load.

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 "Retrieve input schema" only restates the tool name and title without adding scope, format, or distinctions from siblings like list_mcp_server_tools or get_evaluation_config. An agent learns nothing beyond what the name already says.

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?

"Read operation" is a safety statement, not usage guidance. There is no indication of when to call this versus alternatives, no prerequisites, and no conditions for use.

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