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

With no annotations, the description carries the full burden. It does declare 'Read-only' and discloses a scope limit ('No per-slide drop-off'), which is valuable. It says nothing about permissions, rate limits, or pagination of the 'recent sessions' list, which matters for a no-annotation analytics call.

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?

Two dense sentences, front-loaded with purpose, then the default-mode behavior, then the alternate mode, then scope caveats. Every clause carries information; nothing is filler.

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?

No output schema exists, so the description usefully lists the returned fields for both views, which is exactly what's needed. The remaining gap is the undocumented 'id' parameter and lack of permission/pagination context.

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 coverage is 75% and the description adds meaning beyond it: it explains which metrics each 'view' enum value yields and that date_from/date_to apply to the period view. The required 'id' is only documented in the schema ('from list_agents'), so it is not reinforced here.

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?

'Slide Presenter analytics' names a specific resource, and the description enumerates the exact metrics returned for each view mode, so the agent knows precisely what it gets. It stops short of differentiating itself from nearby siblings like get_presentation or get_analytics_agents.

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?

It states that 'summary' is the default and that 'period' requires date_from/date_to, which is real guidance for choosing a mode. It gives no guidance about when to prefer this tool over other presentation/analytics siblings, and no exclusions beyond the parenthetical.

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