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 fully covered. The description adds genuine value by enumerating what each record reports (target, schedule, next occurrence, paused flag), which annotations cannot convey. It stops short of stating ordering, pagination, or whether paused requests are included or excluded.

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 single sentence with no filler, and the item fields are front-loaded where an agent will read them. It is a fragment rather than a complete clause, but nothing is wasted and nothing is buried.

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?

With no output schema, the description usefully maps the expected return shape and annotations cover safety, so an agent can call it. Gaps remain around volume, ordering, and pagination behavior for a list tool, plus whether paused items are filtered, which matter for interpreting results.

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?

Only one parameter with 100% schema description coverage ('Workspace ID'), so the schema carries the burden and a baseline 3 applies. The description's possessive 'a client's' loosely reinforces that the list is scoped to the given workspace, but adds no format or syntax detail.

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 names the resource (a client's recurring requests) and the attributes of each item (what it opens, schedule, next opening day, paused state), so the content is discernible. But it is a noun-phrase fragment with no verb ('List'), and it draws no line against sibling list_requests or get_request, which an agent must choose between.

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 guidance on when to call this instead of list_requests, get_request, or inbox. The only scoping hint is 'a client's', which implies workspace context but never states that workspaceId selects the client or what happens if the workspace has none.

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