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

The annotations already establish read-only, idempotent, non-destructive, closed-world behavior. The description adds useful behavioral scope by saying it returns only approved metadata fields and excludes secrets, contacts, and original files.

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 short, front-loaded, and mostly free of waste. The phrase “through the existing application” is vague and adds little, but the overall structure 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?

For a read tool with no output schema and no schema descriptions, the description is too thin. It does not explain what branding metadata fields are returned, how query filtering works, or how limit/offset affect results.

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?

There are three parameters and schema description coverage is 0%, so the description must compensate. It does not mention limit, query, offset, filtering, or pagination at all, leaving parameter meaning entirely undocumented.

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 gives a clear verb and resource: reading authorised branding metadata. It does not explain how this differs from the many sibling metadata tools, but the resource itself is specific enough to distinguish it in practice.

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?

It states a scope constraint, approved metadata only, but gives no guidance on when to use this tool versus alternatives or siblings. No prerequisites or exclusions beyond data sensitivity are described.

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