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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool 'Changes the name' and 'Returns: Updated item information', which implies a mutation operation with a response, but lacks details on permissions, side effects, error conditions, or whether the change is reversible. For a mutation tool, this is insufficient behavioral context.

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 efficiently structured with three bullet-like statements, each adding distinct value: the core action, usage scope, and return information. There is no wasted text, and key information is front-loaded.

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 mutation tool with no annotations, 0% schema coverage, but an output schema exists, the description is moderately complete. It covers purpose and scope well, but lacks behavioral details like permissions or side effects. The output schema reduces the need to describe return values, but more context on the mutation's impact would improve completeness.

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 0%, so the description must compensate. It implies 'item_id' identifies the target and 'new_name' is the updated name, but doesn't explain ID formats, name constraints, or validation rules. The description adds minimal semantic value beyond what the parameter names suggest, meeting the baseline for low coverage.

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 specific action ('Changes the name') and resource ('any inventory item'), distinguishing it from siblings like 'renameDocumentOrNotebookEntry' which handles different resource types. It explicitly lists the applicable item types (samples, subsamples, containers, templates), making the scope unambiguous.

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 clear context for when to use this tool ('Rename samples, subsamples, containers, or templates'), but does not explicitly state when not to use it or name alternatives. For example, it doesn't contrast with 'renameDocumentOrNotebookEntry' for non-inventory items, though the 'Universal' statement implies broad applicability within inventory.

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