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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that by disclosing the access model: 'shared' means presentations you were given access to, and 'open' ones any signed-in agent may read *and edit*, plus a per-item 'whether you can edit it' field. It omits pagination/scale behavior, keeping it from a 5.

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 scope definition is front-loaded and the field list trails it; the two-part structure is efficient. The one-line scope definitions are somewhat compressed and the field enumeration at the end is a dense run-on, but there is no wasted text.

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?

An output schema exists, so return values need not be spelled out, though the description lists item fields anyway. With the scope semantics fully covered and the access model explained, an agent has what it needs to invoke this correctly; only pagination/result-size behavior is unaddressed.

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 100%, so the baseline is 3; the description earns above baseline by expanding each enum value with meaning the schema does not contain (e.g. 'open' = anybody's, read/edit by any signed-in person or agent). This helps the agent reason about what each scope actually returns.

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 identifies the resource (presentations) and its filtering dimension (scope), and enumerates the three scope categories, so an agent can tell it apart from get_presentation/read_presentation. It never states the verb 'list' explicitly, relying on the name/title, but the enumeration of returned fields makes the list semantics clear.

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 three scope values are defined well enough to pick the right filter, which implies when to use each scope. However, there is no explicit guidance on when to call this listing tool versus siblings like get_presentation, read_presentation, or list_access_requests, and no prerequisites or exclusions are given.

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