export_to_excalidraw_url

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It states the action but does not reveal side effects (e.g., whether a public link is created, if the canvas is modified, or if external service calls are made). The absence of any mention of persistence or access permissions is a notable gap.

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 description is a single, well-constructed sentence that front-loads the action and destination. Every word contributes meaning, with no redundancy or filler.

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 zero-parameter tool with no output schema and no annotations, the description is adequate: it names the action, subject, and output format. However, it leaves out details about the nature of the URL (e.g., whether it's temporary or requires authentication), which would enhance completeness. Still, the simplicity of the tool makes this a minor gap.

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?

The input schema has zero parameters, and the description correctly references an implicit context ('current canvas'). With no parameters to document, the description fully satisfies this dimension, and the baseline of 4 for zero-param tools is exceeded by the clear contextual mention.

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 ('Export') and clearly identifies both the resource ('current canvas') and the destination ('shareable excalidraw.com URL'). It distinguishes itself from sibling tools like export_to_obsidian and export_scene, which target different outputs.

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 a clear use case (when you want to share the canvas via a link) but does not explicitly differentiate from alternatives such as export_scene or export_to_obsidian. No exclusions or conditions are mentioned, leaving the agent to infer when this tool is preferred.

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