style_tablix_row

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

With no annotations, the description carries the full burden and does well: it explains that style is applied to every cell, lists row specifiers (integer, 'header', 'details', etc.), mentions delegation to set_textbox_style_bulk, and specifies the return value structure. It lacks details on error behavior or permissions, but for a style application tool, this is adequate.

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 well-structured and concise. Each sentence adds value: purpose, replacement pattern, row parameter details, style kwargs, delegation, and return value. No unnecessary words, and the information is front-loaded with the primary purpose first.

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 complexity (21 parameters, row specifiers, delegation), the description covers the key aspects: purpose, row types, style kwargs, and return. It does not detail each parameter but references set_textbox_style. The return value is described despite no output schema. Overall, it provides enough context for 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 very low (5%), putting burden on the description. The description lists many style kwargs in parentheses and explains row values, but does not individually define each parameter. It references set_textbox_style for full details, which helps but is not exhaustive. The description compensates partially but could be more complete.

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 tool's purpose: 'Apply the same style kwargs to every cell in a tablix row in ONE call.' It specifies the verb (apply) and resource (tablix row), and explicitly distinguishes it from the pattern of making 12 individual set_textbox_style calls, helping the agent know when to choose this 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?

The description provides clear usage context by stating the tool replaces a multi-call pattern (12-individual-set_textbox_style-calls-per-row). It details the row parameter options and refers to set_textbox_style for style kwargs. However, it does not explicitly state when not to use it or mention alternatives for styling individual cells, but the context is sufficient.

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