save_workbook_as

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

No annotations are provided, so the description carries the full burden. It discloses that the session points to the new file after saving, which is a key behavioral trait. However, it does not mention permissions, overwrite behavior, or error handling, which are important for a file save operation.

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 a single concise sentence that includes the action, the target (absolute path), and the side effect (session points to that file). Every word adds value.

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?

For a simple tool with 2 parameters and no output schema, the description is largely complete. It explains the core behavior and the session change. It could mention return value or errors, but not essential given the tool's simplicity.

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%, so the description must compensate. It adds meaning for 'new_path' by specifying it must be an absolute path. However, it does not describe the 'session_id' parameter beyond its name. This partial compensation earns a 3.

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 saves a workbook to a new absolute path, with the additional behavioral note that the session then points to that file. This distinguishes it from the sibling 'save_workbook' which likely saves to the current path.

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 when to use this tool (to save to a different path) and distinguishes it from the sibling 'save_workbook'. However, it does not explicitly state when not to use it or mention alternatives like 'save' vs 'save as'.

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