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

Adds two facts annotations cannot convey: file contents are not downloaded (metadata only) and the exact return shape { count, next_skip, items }, which is important since there is no output schema. Pagination mechanics are spelled out. It does not address scoping/visibility or error behavior, so not a 5.

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?

Five short clauses, each carrying distinct information, with the most decision-relevant facts (no contents, return shape, paging) up front. No filler or restated title.

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?

Covers everything an agent needs for this 6-parameter, zero-required list tool: what is returned, how to page, how to fetch one record, and how to filter. With readOnly/openWorld annotations already present and no output schema, nothing material is left dangling.

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%, so baseline is 3, but the description earns extra by clarifying the pagination contract (next_skip -> skip) and framing the filters-vs-query split. It does not explain when to prefer filters over query, or whether id is mutually exclusive with the rest.

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 (list) and resource (file records) and enumerates the record fields (name, size, folder, sharing). The sibling tools are nearly all create/list, but this description never explicitly contrasts itself with plutio_list_folders, which an agent could plausibly confuse it with.

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?

Gives concrete routing: 'Pass id to read one record' and 'Filter with exact-match fields or a MongoDB-style query', plus the paging loop via next_skip. It stops short of any exclusion or prerequisite (what happens if id and filters are combined, what permissions are needed).

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