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

Annotations already establish readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered elsewhere. The description adds nothing beyond that — no mention of pagination behavior, ordering, default filtering to open items, or how results relate to the sibling resolve/ack tools.

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 short, but shortness here is under-specification, not conciseness — a single six-word phrase that earns no information beyond the tool name. There is nothing front-loaded because there is nothing to load.

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 needn't be explained, but with four undocumented parameters, four closely related notification siblings, and zero annotation-independent context, the description is far from sufficient for an agent to invoke this correctly.

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 0% across four parameters, and the description compensates for none of it. Nothing explains what 'status', 'severity', 'limit', or 'cursor' mean or what values they accept — the non-obvious default status='open' is left entirely undocumented.

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 verb and resource ('List ... notifications'), which is more than a tautology, but 'TaskTools notifications' is opaque and the description does nothing to distinguish it from siblings like notifications_scan or notifications_summary, which plausibly also read notification data.

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 use this versus notifications_scan, notifications_summary, or notifications_ack. The default status='open' filter exists in the schema but the description never hints at scope or when a plain listing is the right call.

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