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

Annotations already disclose readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful scope by saying it produces AI ASO advice and works with any scraper output. It does not add auth, input-format, or result-format details beyond that.

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 repeats the same core sentence twice and includes a broken ellipsis in the first copy. This duplication wastes space and makes the definition look malformed. The core message is front-loaded, but the structure is not clean.

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?

There is no output schema, so the description should explain return values; it does so at a high level by naming keyword gaps, title rewrites, and positioning. However, it gives little detail about what the input object should contain, even though the schema itself is minimal. For this wrapper-style tool, the description is adequate but clearly incomplete.

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 100%, but the single input object is only described by a link to the actor page. The description says 'Works with any app scraper output,' which loosely characterizes the input, but does not specify expected structure or required fields. Baseline 3 is appropriate because the schema is the primary documentation.

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 clear verb and resource: turning App Store or Google Play scraper results into AI ASO advice. It also lists concrete outputs such as keyword gaps, title rewrites, and positioning. However, it does not explicitly distinguish itself from related siblings like app_store_intelligence or app_review_intelligence.

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 phrase 'Works with any app scraper output' implies usage when the user has scraper results and wants ASO advice. It gives context but no explicit when-not conditions or named alternatives. An agent can infer the context, but routing between ASO-specific and broader app intelligence tools remains ambiguous.

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