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

Annotations already carry the full safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description adds genuinely useful behavioral context beyond them: the key is returned masked, and the payload includes observed SDK config and first-report signals — non-obvious content that also hints the unmasked value lives elsewhere (reveal_sdk_key).

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?

A single front-loaded sentence with no filler. It is somewhat dense and comma-stacked, but every clause identifies real returned content rather than padding.

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?

An output schema exists so return-value detail is not required, and the read-only annotations cover the safety story. For a one-parameter read tool the description is nearly sufficient; only the appId semantics and sibling routing are left unaddressed.

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 0% and the description never mentions the single required 'appId' parameter. The name and pattern make it largely self-explanatory, but the description does nothing to compensate for the documentation gap (e.g., that it is the app UUID rather than a name).

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 ('Inspect') and resource ('an app') and even enumerates the returned facets (masked SDK key, reporter settings, SDK config signals). It does not distinguish itself from siblings such as get_sdk_setup, get_report, or list_apps, which is the main gap.

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 when-to-use, when-not-to-use, or alternative routing is given. An agent must infer from the name that this is the ID-based single-app read versus list_apps for enumeration or reveal_sdk_key for the unmasked key. Nothing in the text names those alternatives.

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