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

With no annotations provided, the description carries the full burden, and it excels by disclosing that no request body is typical, parameters are top-level fields with camelCase/snake_case aliases, and authentication is required. This goes beyond the schema and annotations (which are absent), providing valuable behavioral context.

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 reasonably concise at five sentences, with the main purpose front-loaded. There is mild redundancy between the first two sentences ('Get the auth url' and 'Raw Vikunja REST proxy for...'), but it is not distracting and the overall structure is effective.

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 GET endpoint with no output schema and no annotations, the description is remarkably complete. It covers purpose, usage flow, parameter conventions, authentication, and the next step (using the auth code). This is sufficient for an agent to invoke the tool correctly.

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 properties, so the baseline is 4. The description adds useful parameter conventions (top-level, aliases) even though no parameters exist for this endpoint, which helps understand similar tools. It does not add semantics for specific parameters because there are none.

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 clearly states the specific action: 'Get the auth url from todoist' and identifies the exact endpoint 'GET /migration/todoist/auth'. This is a specific verb and resource, and the purpose is unambiguous even among sibling migration tools.

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 provides clear context: this returns the auth URL for Todoist migration, and the resulting code is used to migrate data. It does not explicitly mention alternatives or when-not-to-use, but the usage scenario is evident. The lack of exclusions prevents a 5.

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