save_workbook

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

No annotations are provided. The description implies writing to disk but does not disclose overwrite behavior, permissions, or format support. For a simple save, it is minimally 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?

Two sentences, no unnecessary words. Efficiently conveys purpose and default behavior.

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 tool is simple. Description covers the essentials. An output schema exists but is not needed for understanding. Could mention return value, but not critical.

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?

With 0% schema coverage, the description adds value by explaining the default behavior when file_path is omitted, which is not in the schema other than default=null.

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 'Save the current workbook to an xlsx file', specifying the verb and resource. This distinguishes it from sibling tools like create_workbook or load_workbook.

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 explains the default behavior when file_path is omitted, providing useful guidance. However, it lacks explicit when-to-use vs alternatives, but sibling context makes it clear.

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