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 mentions 'close a presentation' and a 'save' parameter, but doesn't explain what closing does (e.g., ends editing session, releases resources, potential data loss if not saved), permissions required, or error conditions, leaving significant gaps.

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 appropriately sized with a clear header and bullet points for args and returns, making it easy to scan. It avoids unnecessary fluff, though the 'Returns' line is redundant given the output schema, slightly reducing efficiency.

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?

Given 2 parameters with 0% schema coverage and no annotations, the description provides basic parameter semantics and states the tool's purpose. However, as a mutation tool (implied by 'close'), it lacks details on behavioral traits, error handling, and interaction with siblings, making it minimally viable but incomplete. The output schema mitigates the need to explain return values.

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 0%, so the description must compensate. It adds basic meaning by explaining 'presentation_id' as 'ID of the presentation' and 'save' as 'Whether to save changes before closing', which clarifies intent beyond the schema's titles. However, it doesn't provide format details (e.g., ID format) or deeper context (e.g., default behavior implications), resulting in adequate but incomplete coverage.

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 the verb ('close') and resource ('presentation'), which provides a basic understanding of the tool's function. However, it doesn't differentiate from sibling tools like 'save_presentation' or explain what 'closing' entails versus saving or other operations, making it somewhat vague.

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?

No guidance is provided on when to use this tool versus alternatives such as 'save_presentation' or 'open_presentation'. The description lacks context about prerequisites (e.g., must the presentation be open first?) or exclusions, leaving usage unclear.

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