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 mentions 'Create a dashboard' which implies a write operation, but fails to detail permissions, side effects, or what happens on success/failure. No information on rate limits, idempotency, or response format is included, leaving significant gaps.

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, efficient sentence that directly states the tool's function without unnecessary words. It is front-loaded with the core action, making it easy to grasp quickly.

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 tool has 5 parameters with 0% schema coverage and no annotations, the description is insufficiently complete—it lacks parameter details and behavioral context. However, the presence of an output schema mitigates the need to describe return values, keeping it from being completely inadequate.

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 by explaining parameters. It mentions 'combining multiple worksheets', which hints at 'worksheet_names', but doesn't clarify the purpose of 'dashboard_name', 'width', 'height', or 'layout'. This leaves most parameters semantically unclear beyond what the schema titles provide.

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 action ('Create a dashboard') and the resource ('combining multiple worksheets'), making the purpose immediately understandable. It distinguishes from siblings like 'add_worksheet' or 'create_workbook' by focusing on dashboard creation with worksheets, though it doesn't explicitly contrast with them.

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?

No guidance is provided on when to use this tool versus alternatives like 'create_workbook' or 'add_worksheet', nor does it mention prerequisites such as needing existing worksheets. The description only states what it does, not when or why to use it.

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