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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that results are report definitions with an emailed-by-default flag and that results are paged, but it doesn't state ordering, whether an empty list is possible, or what a caller gets when the form has no reports.

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?

Two short sentences with no filler, and the key identity of the resource is front-loaded. The trade-off is that the telegraphic fragment style omits an explicit verb, making it slightly less readable than a full sentence would be.

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 small read-only listing tool with full schema coverage and an annotation-declared safety profile, this is nearly sufficient. Because there is no output schema, the field enumeration (id, name, format, emailed default) usefully compensates, though the relationship to sibling form/report tools remains unstated.

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%, so both form_id and page are fully documented in the schema, including the 1-based paging and 100-per-page behavior. The description adds nothing parameter-specific beyond the schema, so the baseline 3 applies.

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?

Names a specific resource — the report/PDF definitions attached to a form — and enumerates the fields returned, which clearly separates it from get_form and the other list_* tools. The verb is only implied by the fragment phrasing rather than stated, so it falls just short of a full verb+resource statement.

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 guidance on when to call this versus gocanvas_get_form or gocanvas_list_forms, no prerequisites (e.g. that form_id must exist), and no exclusions. An agent must infer usage entirely from the name and schema.

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