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

Annotations already establish readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description's 'fetch' behavior is consistent and sufficient on the safety front. The description adds a little context by specifying what is fetched (build state, result URL), but it does not disclose any additional behavior such as polling implications or possible states.

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 a single sentence that front-loads the action and the key outputs. Every word contributes: verb, resource, and parameter scope.

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 one-parameter, read-only status tool backed by a full output schema and strong annotations, this is essentially complete. It could add a sentence about expected use after create/publish, but such context lives partly in the parameter description and is not essential for correct invocation.

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?

The input schema has 100% description coverage and the only parameter is well documented as the presentationId returned by create_presentation or publish_narrated_presentation. The tool description merely repeats the parameter name without adding extra format, lifecycle, or constraint details, so it stays at the baseline.

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 ('fetch') and names a concrete resource aspect ('build state and result URL') scoped by presentationId, so an agent knows what the tool returns. It does not explicitly call out sibling tools, but the focus on build state/result URL is enough to distinguish it from analytics, context, and spec tools.

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 explicit guidance is given about when to use this tool instead of get_presentation_analytics, get_presentation_context, get_presentation_spec, or list_presentations. The intended use is only implied by the tool name and the short description.

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