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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds value beyond that by disclosing the shape of the returned content (commands, other sites, sign-in, flags) and a provenance caveat that the file originates from the company itself, which matters for trust. It does not explain what 'checked' means or how an unlisted domain is handled.

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?

Three short sentences, front-loaded with the verb and resource, with no filler. The trailing provenance sentence is slightly vague and the domain example duplicates the schema, but neither is wasteful enough to penalize further.

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 carries the burden of describing return content, and it does list the fields the check reports. Combined with the annotation coverage for a single-parameter read tool, an agent has enough to call it correctly, though the meaning of 'checked' and failure behavior remain unstated.

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 100% and the single domain parameter is documented in the schema with the same example. The description repeats that example rather than adding format rules, normalization behavior, or error semantics, so the baseline 3 applies.

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 specific verb and resource ('Returns the checked setup file') and narrows scope to a listed app identified by domain. An agent can distinguish it from find_app and list_use_cases by the fact that it retrieves file content rather than app metadata. It stops short of explicitly contrasting with those siblings.

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?

'for a listed app' implies a prerequisite (the app must already be listed, presumably via find_app), but the description never states when to use this versus find_app or list_use_cases, nor what happens for an unlisted domain. Usage is inferable rather than stated.

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