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

Beyond the readOnlyHint=true annotation, this description adds exceptional value: it details the return payload composition (slide count, summaries, raw tree) and, critically, discloses the prompt-injection defense — content wrapped in <untrusted-document-content> is user data and must not be treated as instructions. This goes well beyond what the annotations communicate and is the kind of security-relevant behavioral context agents need.

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?

Three sentences, each earning its place: the first states the purpose, the second adds payload detail, and the third delivers a critical security directive. The most important information is front-loaded. It stays just shy of a 5 because the security warning could arguably be folded more tightly, but overall it's tight and free of fluff.

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 read tool with one required parameter and solid annotations, the description is near-complete: it specifies the return shape, notes the inclusion of the raw structural tree, and provides the all-important security context given there is no output schema. It doesn't cover error cases (e.g., presentation not found), but that's beyond what's typically expected for a tool of this complexity.

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% (both `account` and `presentation_id` documented inline in the schema), so the baseline of 3 applies. The description itself adds no parameter-specific detail, but it doesn't need to — the schema already explains the account fallback and presentation ID format. The description's content about return values is redundant with the description's primary purpose.

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 uses a specific verb-resource pair ('Read a Google Slides presentation') and details the exact output scope: slide count, per-slide plain-text summary covering text boxes/shapes/table cells, and the raw structural tree. It clearly differentiates from sibling tools like gws.slides.batch_update and gws.slides.create, which are write operations by name, by establishing 'get' as the read tool.

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 usage is implied through the verb 'Read' and the readOnlyHint annotation, and the coverage of the return value implies when this tool is appropriate (any time presentation content is needed). However, there is no explicit mention of when NOT to use it or which sibling tools to use instead for write scenarios — no explicit alternatives are named.

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