gws-mcp__slides_create

Create a new Google Slides presentation. Returns the presentationId and a placeholder_map for each slide mapping placeholder types (TITLE, BODY, SUBTITLE) to their objectIds — use these with slides_batch_update insertText.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.2/5.0
Behavior4/5

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

Annotations only declare that this is a non-read-only, non-destructive write. The description adds genuinely new behavioral context by disclosing the return payload (presentationId and a per-slide placeholder_map keyed by TITLE/BODY/SUBTITLE), which matters because there is no output schema. It does not mention where the file lands in Drive or permission/account implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the action and followed by the return contract. Every clause carries information an agent needs; nothing is redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter creation tool with no output schema, the description covers the action and the return shape well. Minor gaps remain around the account parameter's effect and where the presentation is stored, but nothing essential to invoking it correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for both parameters (title and account), so the schema already carries the parameter meaning. The description adds no format, constraint, or default details beyond that, making the baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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'), which cleanly separates it from siblings like slides_get, slides_batch_update, and slides_delete. An agent can identify the operation without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description routes the agent forward by naming slides_batch_update insertText as the consumer of the returned placeholder_map, which is clear next-step guidance. It does not state when not to use this tool (e.g., creating from a template or copying an existing deck), so it stops short of full when/when-not coverage.

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