gdocs_append_content

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a mutating operation (appends to the doc) but does not state whether write access is required, whether existing content is preserved beyond 'end', how formatting is interpreted, or any side effects. The insert_line_break default behavior is left entirely to the schema.

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?

A single sentence that front-loads the action and resource, with zero superfluous words. It is appropriately sized for the tool's simplicity.

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 append operation, the description covers the core action and the schema handles parameter detail. However, it lacks usage context (when to choose this over alternatives), prerequisites (valid document ID, write permissions), and any behavioral caveats. It is adequate but not fully complete.

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 description coverage is 100%, so the schema already documents all four parameters and their defaults. The description adds only minimal semantic value ('formatted or plain text' hints at formatting, 'end' mirrors the append concept) but does not explain nuances like how formatting interacts with document styles or how insert_line_break affects output. Baseline 3 is appropriate.

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 states a specific verb ('Appends'), a specific resource ('Google Document'), a location ('to the end'), and content types ('formatted or plain text'). This distinguishes it clearly from sibling tools like gmail_send_email and gdocs_get_document_info, and goes beyond the tool name by specifying the positioning.

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 no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. Although the siblings are in different domains, an agent deciding between append and other document operations (e.g., replace or create) receives no direction.

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