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

Annotations already cover read-only, idempotent, non-destructive, and closed-world, so the safety bar is low. The description adds real value beyond that: secrets are masked in the output, a position index is included for remove_notification, and the level's notification format/title/body are returned — non-obvious details an agent could not infer from the schema.

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?

It is a single short sentence with no padding, which is good, but it is a grammatically incomplete fragment whose clauses ('that level's notification format') are hard to parse. The key facts — what is returned and why the position matters — are buried mid-sentence rather than front-loaded.

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 carries the burden of explaining returns, and it does list secrets-hidden URLs, positions, format, title and body. It still leaves gaps: what 'that level' refers to, ordering, and whether an empty result means no notifications or an invalid tag/monitor.

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 description coverage is 100%, so both parameters are already documented, including the 'instead of the global settings' framing. The description restates the same three-way scoping choice without adding syntax or format detail, so it neither helps nor harms beyond the schema baseline.

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 (Apprise notification URLs) and its three scopes (global settings, tag, monitor), but it is a sentence fragment with no verb — it never says 'list' or 'retrieve'. It also does not distinguish this from the sibling notification_services, which an agent could plausibly confuse with it.

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 implicitly signals usage by noting the position number is meant 'for remove_notification', which hints at a read-then-mutate workflow. However, there is no explicit statement of when to pick this tool over notification_services or when to omit tag/watch, leaving selection to inference.

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