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

The description goes beyond the annotations by specifying the data fields that will be returned, such as 'number of tasks, start and calculated finish.' This provides valuable behavioral context about the output data structure.

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 highly efficient, covering purpose, output detail, and primary use case in a single, structured statement. There is no wasted language.

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 simple read-only list operation with a single boolean flag, the definition is complete. It clearly defines what the agent retrieves and the scope of the list.

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?

Since the schema coverage is 100%, the baseline score of 3 is appropriate. The description does not add semantic meaning or constraints specifically to the 'includeArchived' parameter.

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 action (lists) and the resource (projects accessible by the account). While it is specific about the data returned (id, role, tasks, etc.), it does not explicitly reference a sibling tool to distinguish its scope.

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 functional guidance by stating the tool is used 'to find the projectId that the other tools need.' However, it offers no explicit guidance on when not to use this tool compared to other project-related list tools.

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