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

No annotations are supplied, so the description carries the full burden, and it discloses very little. The word 'draft' hints the result is not published or shared, but the description never says whether the presentation lands in a default folder, whether it is shared with anyone, whether the call is idempotent, or what identifier is returned to reference the new file.

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 with the action verb front-loaded and no filler. It is efficient, though its brevity is the source of the completeness gaps noted elsewhere rather than a virtue in itself.

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 create tool with no annotations and no output schema, the description should at minimum indicate what comes back (presentation ID or URL) since the agent needs that handle for follow-up calls. It also omits where the file is created and any permission requirements, leaving the definition inadequate for a mutation with real side effects.

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% and the nested slide structure (title plus bullet_points) is fully documented in the schema, so the baseline of 3 applies. The phrase 'structured slides' loosely signals that slides are passed as objects rather than raw text, but adds no constraint or format detail beyond the schema.

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?

States a specific verb and resource: 'Create a new Google Slides presentation draft with structured slides.' An agent can tell this is a creation tool for Slides, distinct from drive_search_files. It stops short of naming an alternative or stating the scope of what 'structured slides' means in practice.

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?

There is no guidance on when to use this versus other creation tools (e.g., gmail_create_draft, github_create_pr_draft) or versus searching existing files. No prerequisites, no mention of required Drive/Slides permissions or whether a target folder can be chosen. The agent is left to infer everything about selection.

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