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

With no annotations provided, the description carries the transparency burden and does a solid job: it discloses authentication requirements, the fact that a request body is usually not required, parameter naming conventions (camelCase and snake_case aliases), and the top-level parameter convention. It does not detail error behavior or exact response structure, but it clearly indicates this is a read-only status check.

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 compact but information-dense, front-loading the core purpose immediately. Every sentence contributes useful operational details (endpoint, response meaning, use case, body requirements, parameter aliasing, authentication), with no filler or redundancy.

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 status endpoint with no output schema, this description is remarkably complete: it states what the endpoint does, which specific migration it applies to, how results should be interpreted, when to use it, authentication requirements, and body conventions. An agent can correctly select and invoke this tool without additional documentation.

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, so the schema itself covers all parameter documentation. The description adds useful context about path/query parameters being top-level fields and the acceptance of camelCase and snake_case aliases, which explains the tool's overall invocation behavior beyond the empty schema.

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 tool's purpose with a specific verb and resource: 'Get migration status' and names the exact endpoint 'GET /migration/todoist/status'. It also explains the return semantics ('Returns if the current user already did the migation or not'), and the explicit Todoist endpoint distinguishes it from the many 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?

The description provides a clear use case: 'This is useful to show a confirmation message in the frontend if the user is trying to do the same migration again.' It also notes authentication is required and that a request body is usually not needed. However, it does not explicitly mention when not to use this tool or name alternatives, so it stops short of a 5.

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