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

The description implies a read-only listing operation, but readOnlyHint is false, indicating the tool is not read-only. This is an annotation contradiction. The phrase 'with what each one is building' adds some return-content context, but the conflicting annotation is a serious transparency issue.

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 filler. It efficiently conveys the action, scope, and the useful detail of what each project is building.

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 parameterless list tool with an output schema available, the description provides the essential invocation context: list projects in the workspace and their purpose. No pagination, filtering, or return-format details are needed because there are no arguments and the output schema can describe the response.

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 tool has zero parameters and the schema fully documents that with an empty properties object and 100% coverage. There is nothing for the description to clarify about parameters, so the zero-parameter baseline applies.

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?

Clearly states the action ('List') and resource ('projects in this workspace'), and previews the content ('what each one is building'). This distinguishes it from sibling project-management tools like create_project, archive_project, delete_project, and list_roadmap.

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 makes the use case evident: get an overview of projects and their purpose in the current workspace. It does not explicitly state when not to use it or point to alternatives for status/roadmap details, but for a simple list tool the context is clear.

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