todoist_test_connection

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

The description indicates a read-only, side-effect-free operation (testing), but does not explicitly state that no data is modified or that it's safe to call repeatedly. With no annotations, the description should explicitly label it as read-only.

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 with no fluff. Every word earns its place, conveying purpose and scope efficiently.

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, no-output-schema tool, the description is mostly complete. However, it could mention expected results (e.g., success/failure indication) to reduce ambiguity.

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?

No parameters exist, so schema coverage is 100% by default. The description adds no extra meaning but is not required to. Baseline 4 is appropriate.

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 tests the Todoist API connection and validates token authenticity. This verb-resource pair is specific and distinct from sibling test tools like 'todoist_test_all_features' and 'todoist_test_performance'.

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?

No guidance on when to use this tool versus alternatives. While the description implies it's for initial setup or troubleshooting, it does not explicitly mention typical usage context, prerequisites, or when to prefer sibling test tools.

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