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

No annotations are provided, so the description carries the full burden. It does add real value by disclosing ordering/scope ('most recent', 'your') and by enumerating the status values that aren't in the schema. However, it says nothing about result limits, pagination, or the default number of documents returned.

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; the scope and the filter come first. Every clause earns its place.

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?

With no annotations, no output schema, and 0% schema coverage, the description should close more gaps. It omits the meaning and default of `limit`, pagination behavior, and what a returned document contains, so an agent still has to guess on several fronts.

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% with two parameters. The description fully compensates for `status` by enumerating the five valid values, which the schema leaves as an unconstrained string. It says nothing about `limit`, leaving half the parameters 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?

States a specific verb+resource ('list documents') plus the scope ('your most recent documents'), which distinguishes it from the single-resource get_document sibling. It does not explicitly name siblings, but the plural/list framing makes the boundary obvious.

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?

'optionally filtered by status' implies when the filter applies, but there is no guidance on when to reach for this versus get_document or other siblings, no note about default behavior when no status is supplied, and no prerequisites.

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