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

The annotations already declare this as a non-destructive, read-only operation, and the description adds useful context by stating the required `projects:read` permission and that results are paginated. It stops short of explaining pagination behavior or response format, but it provides meaningful operational context beyond the annotations.

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 short and front-loads the main action before adding pagination and permission details. The initial 'List projects' line slightly duplicates the following sentence, but overall there is little wasted text.

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 tool with annotations covering safety, the description gives the essential context: organization scope, pagination, and permission requirements. However, with no output schema and no explanation of the returned project representation or pagination mechanics, it is only minimally sufficient for an agent to invoke and interpret the tool confidently.

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 for undocumented parameters. It only says the list is paginated, which hints at the nested `page` and `pageSize` fields but does not explain their defaults, constraints, or usage, leaving most parameter semantics to inference from property names.

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 states a clear verb and resource: listing projects in the organization. It is understandable without opening the schema, but it does not explicitly distinguish this operation from sibling tools such as projects-retrieve or projects-duplicate.

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 implied by the phrase 'List the projects in the organization', which is appropriate for retrieval of all projects. However, the description does not state when to use this tool instead of projects-retrieve for a single project, nor does it mention any exclusions or edge cases.

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