canva_export_design

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

No annotations are present, so the description carries the burden. It usefully discloses that the tool returns download links and supports multiple formats, but it does not mention potential asynchronous behavior, long export times, permission requirements, or any errors that might occur. This is adequate but not highly transparent.

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 states the action, resource, supported formats, and result. There is no filler or redundant content; every part 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?

For a simple export tool, the description plus the fully documented schema is basically usable: provide a design ID and format, get download links. However, without annotations or an output schema, the definition does not mention timing, side effects, auth prerequisites, or how the tool relates to sibling tools. It is complete enough for a basic call but leaves gaps for an autonomous agent.

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 the schema fully documents all four parameters. The description adds no real parameter semantics beyond listing some formats, and it even omits gif and mp4, which the schema's enum allows. This does not contradict the schema, but it does not add value either.

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 uses a specific verb ('exporta'), names the resource ('diseño de Canva'), and states the outcome (returns download links). This clearly distinguishes the tool from siblings like canva_get_design, canva_list_designs, and canva_create_design.

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?

The description implies use when a downloadable file export is needed, but it never explicitly states when to use this tool versus alternatives like canva_get_design or canva_list_designs. No exclusions or conditions are provided, so the agent must infer usage from the name and description.

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