close_file

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

The description discloses that the tool is destructive (consistently with annotations) and adds crucial context about requiring explicit confirmation for closing all sessions. This goes beyond the annotations and clearly informs about potential data loss.

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, using two short sentences that front-load the action and key variants. Every word adds value, and there is no unnecessary information.

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 has 4 parameters, no output schema, and moderate complexity. The description covers basic usage but lacks details on return values, error conditions, or behavior when both file_path and google_doc_id are provided. Given the lack of output schema, more completeness would be beneficial.

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 50% schema description coverage, the description adds context about the 'clear_all' and 'confirm' parameters through the phrase 'close all sessions with explicit confirmation'. However, it does not elaborate on parameter behavior beyond that, leaving some ambiguity for the undocumented parameters.

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 action ('Close') and the resource ('file session'), and distinguishes between single session and all sessions. It also specifies supported file types, making the purpose specific and distinct from siblings like 'save' or 'read_file'.

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 indicates when to close a single file vs. all sessions with explicit confirmation. While it does not explicitly list alternatives or when not to use, the guidance is clear and sufficient for most use cases.

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