list_projects

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

The annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds nothing beyond that — no mention of pagination, result ordering, or whether all projects or only ones the caller can see are returned.

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?

It is short and front-loaded, which is appropriate, but the second sentence ("GET /projects.") conveys nothing an agent can act on and is effectively redundant with the name. Concise but one of the two sentences does not earn its place.

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 zero-parameter read tool with complete annotations and no output schema, the description is minimally sufficient to invoke it. However, with no output schema the description could reasonably say what is returned (id/name fields) or whether results are paginated, and it does neither.

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 takes zero parameters, so the baseline is 4: there is nothing for the description to compensate for, and the schema fully covers the (empty) input.

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?

"Get projects" essentially restates the tool name and the raw HTTP route (GET /projects), adding no verb specificity beyond the name. It does not distinguish this list-all operation from the sibling get_project (singular) or list_recent_project_events, so an agent gets no disambiguation signal.

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 such as get_project for a single project, and no note about filtering or scope. The default assumption (list everything) is left to inference rather than stated.

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