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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered. The description adds useful scope context ('writer-approved public' implies filtering to approved, public-facing assets rather than all assets), but says nothing about result size, pagination, or ordering.

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 slightly redundant in phrasing ('writer-approved ... for a writer'), which keeps it just short of ideal.

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 one-parameter read tool with full annotation coverage and no output schema, the description is adequate and even characterizes the return content as share URLs. It nonetheless omits pagination/size behavior, which an agent listing 'all' assets would want to know.

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 there is one required parameter, writerSlug. The description implies the parameter identifies the writer whose assets are listed, which is a reasonable mapping, but it adds no format, slug-shape, or validation detail beyond the schema's type declaration.

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 names a specific verb ('List') and a precise resource ('writer-approved public share URLs for a writer'), which is more informative than the title alone. It does not, however, differentiate itself from plausible siblings like get_writer_profile or list_project_assets, so an agent must infer the distinction from the names.

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?

There is no explicit when-to-use or when-not-to-use guidance. The phrase 'for a writer' hints that writerSlug is the required selector but gives no indication of when this is preferable to get_writer_profile or list_project_assets.

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