Apply Alternating Row Colors

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

Annotations lack readOnlyHint or destructiveHint, so the description carries full burden. It states a mutation (applying colors) but does not disclose reversibility, side effects, or that the operation modifies the document. Minimal 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 extremely concise at eight words and one sentence. It communicates the core function without any redundancy. Every word serves a purpose.

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 simple schema and lack of output schema, the description is incomplete. It does not mention the return value (likely void), file existence requirements, or handling of invalid inputs. The tool is underspecified for a reliable agent call.

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% and the description provides no parameter details. The agent gets no help understanding what filename, table_index, color1, or color2 mean or how to use them correctly. The defaults are in the schema but not explained.

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 (apply) and the resource (alternating row colors) with a purpose (better readability). However, it does not distinguish from sibling tools like format_table or set_table_cell_shading, leaving the agent uncertain about when to choose this specific tool.

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 on when to use this tool versus alternatives. No prerequisites, exclusions, or examples provided. The description is too brief to inform decision-making among many table-related sibling tools.

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