List Firebase iOS apps

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

No annotations are provided, so the description carries the full burden. It never states that this is a read-only operation, that results may be paginated, how the default project is resolved, or anything about the response shape.

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?

One tight, front-loaded sentence with no filler. It is efficient, though the terseness contributes to the gaps in other dimensions rather than being a model of well-scoped brevity.

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, and an undocumented pagination parameter, the description leaves an agent guessing about paging behavior, default project resolution, and return contents. It is not complete enough for correct invocation beyond the trivial case.

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 only 50%: projectId is documented in the schema, but pageToken has no description anywhere. The description adds no parameter meaning at all, so it fails to compensate for the coverage gap on pagination.

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 specific verb ('Lists') and resource ('iOS apps registered under a Firebase project'), which cleanly separates it from the android/web listing siblings by platform. It does not explicitly name those siblings, so it stops short of the 5-level differentiation.

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?

The purpose implies when it applies (enumerating registered iOS apps for a project), but there is no explicit guidance, no prerequisites, and no mention of the sibling listing tools an agent might confuse it with. Minimum viable for an obvious list operation.

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