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

Annotations already cover read-only/idempotent/non-destructive, so the bar is lower; the description adds real domain behavior: that 'Uncertain' does not equal delivered and that owner received/cancel declarations do not rewrite network outcomes. It also discloses the tickets:read auth requirement. It stops short of describing payload size or retention limits.

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?

Four compact sentences, front-loaded with what the tool returns, then pagination and semantic caveats. Dense but each sentence carries distinct information; the terse style borders on cryptic but no sentence is wasted.

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 and 4 undocumented parameters at 0% coverage, the description should do more: the return payload shape, the limit/default behavior, and the exact cursor parameter names used on input are left unaddressed. The semantic caveats partially compensate, but key calling details are missing.

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 0%, so the description must carry the load. It explains the pagination model (attempts and recoveries paged independently), but it names cursors 'next_before_attempt'/'next_before_recovery_id' while the schema properties are 'before_attempt'/'before_recovery_id', and it never mentions limit, defaults, or the UUID format. This adds partial meaning but introduces a naming ambiguity.

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 gives a specific verb+resource: inspecting the retained notification payload and delivery state for a single delivery, including attempt and recovery histories. It is clearly distinct from the list_attention_notification_deliveries sibling, though it never names siblings or states the by-ID retrieval scope 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?

It implies usage context (paging attempts/recoveries separately, interpreting 'Uncertain' vs delivered) but never says when to choose this over get_attention_notification_receipt, get_delivery_timeline, or reconcile/retry siblings. A reader must infer the routing decision.

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