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

With no annotations provided, the description carries full burden. It discloses the critical behavioral trait: requires user approval via confirm=True. However, it doesn't mention other important behaviors like whether this is a destructive operation, what permissions are needed, rate limits, or what happens to existing slide decks. The description adds some value but leaves 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 and well-structured: purpose statement first, then parameter details in a clear format. Every sentence earns its place by providing essential information. Minor improvement possible by integrating the confirm requirement more seamlessly with the purpose statement.

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 7 parameters with 0% schema coverage and no annotations, the description does a good job explaining parameter semantics. The presence of an output schema means return values don't need explanation. For a content generation tool with user approval requirement, the description covers the essential context, though could better address behavioral aspects like what 'generate' entails operationally.

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 provides meaningful semantics for all 7 parameters: explains notebook_id is a UUID, source_ids default behavior, format options, length options, language codes, focus_prompt purpose, and confirm requirement. This adds substantial value beyond the bare schema, though some details like BCP-47 code examples could be more complete.

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's purpose: 'Generate slide deck' specifies the verb and resource. It distinguishes from siblings like 'infographic_create' or 'report_create' by focusing on slide decks specifically. However, it doesn't explicitly differentiate from other content generation tools beyond the resource name.

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 usage context: 'Requires confirm=True after user approval' indicates when to use it (after approval) and implies a prerequisite interaction. It doesn't explicitly mention when NOT to use it or name specific alternatives among siblings, but the approval requirement provides practical guidance.

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