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

With no annotations, the description carries full burden. It thoroughly explains the tracked parameter behavior (default creates tracked changes, false overwrites directly) and notes the author field. However, it omits side effects like document protection or error handling for out-of-bounds indexes.

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 front-loaded with the core purpose and then provides a paragraph on tracked behavior followed by a parameter list. It is reasonably concise for the complexity, though the docstring could be shortened or separated to improve readability.

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?

The description covers the main functionality and parameter details. An output schema exists but the description does not mention return values, though the rule says it need not. Missing error handling context, but overall sufficient for a tool with 7 parameters and a focused behavior.

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 input schema has 0% description coverage, but the description provides a full docstring for all 7 parameters, including defaults, usage context (e.g., author used only when tracked=True). This adds significant meaning beyond the schema's bare names and types.

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 modifies a table cell, with a specific verb and resource. It includes detailed behavior for tracked changes, distinguishing it from sibling tools like delete_text or get_cell_text. The purpose is immediately understandable.

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 implies use for changing cell text but does not explicitly state when to use it over alternatives (e.g., replace_text). No guidance on prerequisites or when not to use it, leaving the agent to infer based on name and parameter context.

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