A3.5/5.0

Behavior3/5

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

No annotations are attached, so the description must carry behavioral disclosure. It does provide a concrete operational constraint (90s timeout) and implies an installed-app prerequisite, which is useful. However, it doesn't disclose side effects on the device, permission/auth requirements, or failure behavior, so the burden is only partially met.

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?

Two short sentences, front-loaded with the operation and followed by the one critical constraint. Every word earns its place.

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

Completeness3/5

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

Given a very large schema (18 params) and no annotations, the description provides only the core action and timeout; it leaves side effects, usage context, and device-selection nuance to the schema. The rich schema and output schema offset some gaps, but the absence of any behavioral or usage context beyond the timeout makes the description only minimally complete.

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

Parameters3/5

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

Schema description coverage is high (~89%), so the baseline is 3. The description names the two central concepts (app, payload) but adds no detail on payload shape or selector semantics; the schema already carries those details. Since app has no schema description and payload has only a type oneOf, a little more explicit parameter context would improve it.

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 sentence identifies a concrete operation ('Deliver push notification payloads') and a target ('an installed app'), so an agent can distinguish this push-notification tool from unrelated generic actions like install or click. No sibling tool appears to cover push notifications, so the description's specificity resolves the otherwise ambiguous name.

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

Usage Guidelines2/5

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

No guidance about when to choose push over alternatives or when not to use it. The description only states what it does and the timeout; the intended selection context is left to inference. With no comparable sibling, at least a note on prerequisites or when to use it would be needed.

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