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

The annotations already state readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral context by enumerating what the tool returns—fields, roles, options, and an example—which is especially valuable because there is no output schema.

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 definition is one compact sentence that front-loads the returned content and then enumerates both form variants. It is appropriately sized for a simple one-parameter lookup tool, though the noun-phrase opening is slightly less direct than an explicit verb-led statement.

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 simple read-only metadata lookup with one required enum parameter and no output schema, the description is largely complete: it identifies the available forms and the kinds of content returned. The main missing piece is explicit guidance on when to use this tool versus the sibling registration tools.

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%, and the single form parameter has an enum with descriptions for both values. The description restates the same form meanings but does not add syntax or format guidance beyond the schema, so the baseline score of 3 is appropriate.

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 specifies the resource clearly: the fields, roles, options, and example for one of two named GCS registration forms. It also distinguishes the two form variants by audience. However, it does not use an explicit verb such as 'returns' and does not explicitly contrast this retrieval tool with the sibling registration actions.

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 description implies the tool is for inspecting registration form content, but it gives no explicit when-to-use guidance. It does not mention when to call this instead of siblings like register_for_gcs or register_as_media, nor does it state prerequisites or exclusions.

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