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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful scope context ('YOUR presentations', 'you or your agents sent') and the default/scope behavior of include_decided, but does not disclose pagination or filtering behavior.

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?

A short, front-loaded single sentence that leads with the default value and follows with the alternative. It is efficient, though it spends its length duplicating the schema rather than adding new routing information.

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 explained, and the default behavior is disclosed. However, for a list tool sitting among many siblings, the absence of any when-to-use or alternative-tool guidance leaves a real gap.

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 both parameters are already documented in the schema. The description largely restates the enum semantics already present, adding only the 'YOUR presentations' emphasis. Baseline 3 is appropriate when the schema does the heavy lifting.

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 makes clear this lists access requests and splits them into incoming vs outgoing with a stated default. It is specific about the resource and scope, though it never states the verb outright and does not distinguish itself from siblings like get_access or answer_access_request.

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 explains what the two directions mean but gives no when-to-use guidance, no prerequisites, and no routing to alternatives such as answer_access_request (responding) or get_access. The agent must infer usage entirely.

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