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

Beyond the annotations, the description discloses the exact return shape, explains that the returned link carries no access token, warns that opening it may show a status page and require a signed-in Padlet browser session, and clarifies that the tool prepares the link rather than starting the export. These are important behavioral details an agent could not infer from the annotations alone.

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?

The definition is front-loaded with purpose and supported formats, then uses bullets for caveats and parameter notes. It is somewhat long and repeats a few details already in the schema, such as the spreadsheet/XLSX mapping and PDF page options, but the structure keeps the key information scannable.

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?

Even without an output schema, the description supplies the return contract as success with export_url and format or failure with message. Combined with annotations and a fully described input schema, it gives the agent enough information to invoke the tool correctly and understand the main limitations.

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 already 100%, so the schema carries the core parameter documentation. The description still adds useful semantics, especially format-specific constraints like page_size and orientation applying only to PDF, spreadsheet meaning XLSX, zip_attachments refusal conditions, and the absence of id lookup for wall_url.

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 and resource: 'Export a padlet' and immediately enumerates the supported output formats. No sibling tool performs exports, so the action is clearly distinguishable from list/get/update tools even without naming one.

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?

It gives clear context for when to use the tool: to prepare a plain download or status link, and explicitly notes that it does not start the export. It also provides important constraints such as sandbox export being unsupported and zip_attachments being refused when there are no downloadable attachments. It does not explicitly name an alternative tool, but none of the siblings is an export equivalent.

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