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 action ('Insert') but doesn't mention whether this is a write operation (implied), what permissions are required, if it's destructive to existing content, or details about error handling. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 front-loads the core action and key parameters without any wasted words. It's appropriately sized for the tool's complexity and gets straight to the point.

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's moderate complexity (4 required parameters), 100% schema coverage, and the presence of an output schema (which handles return values), the description is reasonably complete. However, it lacks behavioral context (e.g., permissions, error cases) and usage guidelines, which are notable gaps for a mutation tool with no annotations.

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 description mentions 'specified dimensions' (hinting at rows/columns) and 'at a given index', which aligns with the input schema parameters. Since schema description coverage is 100%, the schema already fully documents all parameters, so the description adds minimal value beyond restating what's in the schema, meeting the baseline of 3.

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 ('Insert'), resource ('a new table'), and key parameters ('with specified dimensions at a given index'), making the purpose immediately understandable. However, it doesn't explicitly distinguish this tool from sibling tools like 'insert_table_column' or 'insert_table_row', which would require a 5.

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 'create_google_doc' (for initial document creation) or other table-related tools (e.g., 'insert_table_column'). It lacks context about prerequisites, such as needing an existing document, or exclusions, like not being for modifying existing tables.

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