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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real value by disclosing the access-scoped result set (only projects the caller can open) and that each entry carries the caller's role. However, it says nothing about pagination behavior despite the presence of limit/cursor, which is the main undisclosed trait.

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 tight sentence with no filler, front-loaded on the verb and scope. Nothing redundant and nothing padding the definition.

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 paginated list tool with no output schema and two undocumented parameters, the description is too thin: it never explains paging, result ordering, or what fields accompany the role. It covers the what but leaves the agent without enough to call it correctly on a large project set.

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?

Both parameters (limit with a 1-100 range, cursor) have 0% schema description coverage, so the description carries the full burden of explaining them — and it mentions neither. An agent gets no signal about default page size, maximum of 100, or how to continue with a cursor.

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 gives a specific verb and resource ('Lists the projects'), plus a scope qualifier ('the caller can open') and a hint at the payload ('the caller's role in each'). That distinguishes it from get_project (single project) and list_project_members (members rather than projects), though it does not name any sibling explicitly.

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?

Usage is only implied by the 'projects the caller can open' framing, which suggests it's the entry-point enumeration before drilling into a project. There is no explicit when-to-use, no statement of when to prefer get_project or search_workspace, and no mention of prerequisites or exclusions.

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