save_document

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 explains the optional file_path parameter and default behavior (saves to current path if not specified), but does not disclose whether the operation overwrites, requires confirmation, or what happens if the document is unsaved. This is adequate but not rich.

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 extremely concise: two sentences plus an Args/Returns section. Every sentence earns its place with no fluff. The structure is front-loaded with the core purpose.

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 save tool with one parameter and an output schema, the description covers the essential behavior. It explains the parameter and return value. However, it could describe what 'current path' implies (e.g., must have been opened or saved before) for full completeness.

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 schema description coverage is 0%, so the description must compensate. It clearly explains the 'file_path' parameter: 'Optional new path to save as (uses current path if not specified).' This adds meaning beyond the schema's type and default, making it easy for an agent to use correctly.

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 document,' which is a specific verb+resource. It distinguishes from siblings like open_document, close_document, copy_document, and convert_document by implying persistence of the current state.

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 provides clear context: this tool is for saving the current document. While it does not explicitly state when not to use it or list alternatives, the usage is straightforward and implied by the verb 'Save'. No exclusions are needed.

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