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

Adds substantial context beyond the annotations: explains pagination via next_cursor, and discloses the setup_required fallback response including eligible workspaces and steps to create a project. The annotations already cover read-only and idempotency; the description contributes the non-obvious edge behavior an agent could not infer.

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?

Five tight sentences, front-loaded with purpose and usage, then edge behavior and pagination. No sentence is filler.

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?

Given three optional params, no output schema, and rich annotations, the description covers purpose, pagination, and the setup_required branch well. It omits detail on the shape of returned project objects and the limit/workspaceId semantics, which would complete the picture.

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?

Schema description coverage is 0%, so the description must compensate; it maps cursor to 'next_cursor' follow-up and implies workspace scoping via 'within one workspace'. It doesn't document limit bounds or that workspaceId is a UUID filter, leaving some gap.

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?

States a specific verb and resource ('List accessible Replo projects') with scope (optionally one workspace), and distinguishes it from siblings like get_project and list_workspaces by naming the resolution purpose. An agent can tell this apart from create_project and get_project without opening either schema.

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?

Gives a clear when-to-use trigger: 'resolve the project for the user's Replo request'. It also states a negative boundary ('Listing does not create a project'), implicitly routing creation to create_project, but doesn't name that sibling explicitly.

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