Notification status

notification_status

Read-onlyIdempotent

Check a notification's delivery status: queued, sending, sent, or failed. Note that 'sent' does not confirm the recipient has read it.

Instructions

Read queued/sending/sent/failed status. 'sent' does not confirm the user read it.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is covered. The description adds a valuable behavioral nuance: 'sent' does not confirm the user read it, which clarifies the semantic limits of the status field. This goes beyond what annotations express.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two tight sentences. The core action is front-loaded with a concise list of statuses, followed by a single caveat that adds real value. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only tool with one parameter, an output schema already present, and a clear sibling contrast, the description covers the essential behavior. The caveat about 'sent' prevents a common misinterpretation. Nothing critical for invoking the tool correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description bears the burden of explaining the parameter, but it does not mention notification_id at all. The schema only provides the name and type, leaving the agent to infer what the ID refers to. This is a clear gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Read') on a well-defined resource (notification status) and enumerates the possible states ('queued/sending/sent/failed'). This clearly distinguishes it from the sibling tool 'notify', which presumably creates/sends notifications. An agent can immediately tell what this tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this is for checking delivery status, likely after using 'notify', but it does not explicitly say when to use this tool versus alternatives or mention any exclusions. The usage context is inferable from the read-vs-write contrast with 'notify', but the guidance is not explicit.

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