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

With no annotations, the description carries the full burden and does well: it discloses dual-mode behavior, an auth prerequisite (linked account via transport auth), and the downstream meaning of the data. It omits error/empty behavior, but core behavioral traits are covered.

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?

Three dense sentences with the dual-mode behavior front-loaded and zero filler. Every sentence adds routing, data meaning, or a prerequisite.

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 no-annotation, single-param, no-output-schema tool, it supplies purpose, mode behavior, data provenance, and auth requirements. Return shape is only loosely sketched ('exact files'), a minor gap given no output schema exists.

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 the schema already documents the single name parameter and its omit-to-list semantics. The description reinforces this but adds no syntax or format detail beyond the schema, matching the baseline for fully-covered schemas.

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 (lists admin page set names / returns a set's exact files) with dual-mode scope. It also distinguishes itself from siblings by naming purchase_scaffold and explaining the relationship via the admin_page_set param.

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?

Explicitly tells the agent when to omit name (list set names) versus pass name (get one set's files). Context for broader usage is given via the purchase_scaffold reference, though the sibling set_adminpageset is not addressed.

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