push_setup_apns

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

No annotations are provided, so the description carries the full burden of explaining side effects. It only says 'Generate... setup' but does not disclose whether files are written, credentials are required, existing configuration is modified, or what the output is. 'Pro feature' adds a gating detail but no behavioral context.

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?

The description is a single short sentence with no filler and the core purpose is front-loaded. It is under-specified, but as pure conciseness it is efficient.

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 annotations, no output schema, only one documented parameter, and a sparse description, an agent lacks enough context to know what will be created, modified, or required. The description is barely sufficient for a simple setup tool.

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 only 50% because api_key lacks any description. The description does not explain what api_key represents or how directory is used beyond 'Project directory' already present in the schema, leaving the purpose of the key ambiguous.

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 states a concrete resource ('Apple Push Notification setup') and a generating/setup action, so an agent can tell this concerns APNs. It differentiates enough from the sibling tools push_setup_fcm and push_setup_web because 'Apple' is explicit, though it does not name those alternatives.

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 is given about when to use this tool versus push_setup_fcm, push_setup_web, or other setup tools. The phrase '(Pro feature)' hints at entitlement but not at when this tool is the correct choice.

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