analyze_sheet_structure_tool

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

With no annotations, the description carries full burden. It clearly indicates it is a read-only analysis by listing what it returns (sheet info, tables, charts, etc.) without mentioning any side effects or destructive actions. It could be improved by noting any performance impact or permissions needed.

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 with a front-loaded purpose, a bullet list of contents, and separate Args/Returns sections. It is efficient, though the Args section is redundant with the schema.

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 simplicity and the presence of an output schema, the description covers all relevant aspects: sheet info, tables, charts, slicers, drawings, developer metadata, and a summary. It is complete for its purpose.

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 repeats parameter names and descriptions already present in the input schema (100% coverage), adding no new semantics beyond what the schema provides.

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 'Analyze a specific sheet's structure - quick overview' and lists the types of elements it covers (tables, charts, slicers, etc.), distinguishing it from sibling tools that focus on specific data retrieval or modification. The tool's purpose is uniquely about structural analysis.

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 usage for a quick structural overview but does not explicitly state when to use it over alternative tools like get_table_metadata or get_sheet_cells. No guidance on when not to use or alternatives is provided.

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