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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is covered elsewhere. The description adds nothing beyond that: it says nothing about pagination, default page size, whether all projects are returned at once, or the shape of the result, which is the value a description should add when annotations exist.

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?

One short sentence, front-loaded with the verb and resource, with no filler. It is efficient, though the extreme brevity edges toward under-specification rather than ideal sizing for a seven-parameter listing tool.

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?

There is no output schema, seven optional parameters, and pagination behavior that the description never addresses. An agent cannot tell from the description whether results are paginated by default, how filtering interacts, or what a project record contains, so the definition is incomplete for a tool of this complexity.

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 100%, so all seven parameters (page, type, expand, status, per_page, created_after, created_before) are already documented in the schema. The description contributes no additional meaning about filtering or pagination semantics, so the baseline 3 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?

The description gives a specific verb and resource ('List ... projects') and scopes it to 'this community's', so an agent knows it retrieves a collection rather than a single item. It does not, however, distinguish itself from siblings like get_project or list_templates, so it lands at a clear-but-undifferentiated 4.

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?

There is no when-to-use guidance, no mention of alternatives (get_project for a single project, create_project for creation), and no indication of prerequisites. The agent is left to infer usage purely from the name.

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