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

Goes well beyond the annotations (readOnly, idempotent, non-destructive, closed-world) by disclosing the auth model and required scope, the credential-derived workspace scoping, and the important partial-disclosure behavior that webhook addresses are never returned whole. That masking detail is exactly the kind of behavior an agent cannot infer from structured fields and would otherwise misreport.

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?

Information-dense with little true padding, but the first sentence is a verbless fragment ('With your trooth.co sign-in, or the workspace's agent key with the settings area'), so the actual purpose is not front-loaded and the opening reads awkwardly before the agent learns what the tool returns.

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?

Complete for a zero-parameter read tool with an output schema: auth, scoping, the masked-field behavior, and a summary of returned structure are all present. An agent has everything needed to call it and report results correctly without further discovery.

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?

Zero parameters, so the baseline is 4; the schema is empty and cannot carry meaning. The description adds genuine semantic value by stating that workspace comes from the sign-in or key and never from an argument, which prevents an agent from inventing a workspace parameter or asking the user for one.

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?

States a concrete resource ('Settings, Notifications') and enumerates exactly what is returned: alert destinations with id, kind, events, enabled state, routable events, and weekly reminder field coverage. This distinguishes it implicitly from trooth_notifications_list (event feed) and trooth_notifications_update (mutation) by content, but never names a sibling explicitly.

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?

Prerequisites are unusually well covered: it states the two acceptable credential types (trooth.co sign-in or workspace agent key with settings access, Bearer tra_...) and that workspace scope is derived from credentials, never an argument. However, it gives no explicit routing guidance for when to prefer this over trooth_notifications_update, trooth_webhooks, or trooth_alert_destination_add/remove — 'Read only' only implies the write alternative.

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