Format Cell Text

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

Annotations provide only a title, so description bears full burden. It does not disclose side effects (e.g., overwriting existing formatting), supported formatting options, or any behavioral traits beyond the basic action.

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?

One sentence, but it is incomplete rather than concise. The description sacrifices necessary detail for brevity, making it insufficient.

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?

With 11 parameters (4 required), no output schema, and a one-sentence description, the tool is severely under-documented. It fails to explain cell location parameters or formatting options, leaving agents guessing.

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 coverage is 0%, and description adds no meaning to parameters. While parameter names like 'bold' and 'italic' are somewhat self-explanatory, the description should explicitly mention supported formatting fields.

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 it formats text within a specific table cell, defining the action (format) and resource (text in a cell). While somewhat vague on 'format', it distinguishes from siblings like 'format_table' and 'format_text'.

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 or exclusions provided. The description lacks context for optimal usage.

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