list_versions

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is fully covered by structured data. The description adds the useful scoping note that shared versions are included, which is real context beyond the annotations. It does not mention pagination or return shape, so it adds only moderate value.

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 single sentence is short and front-loaded with no wasted words. However, it is a bare noun phrase fragment with no verb, and the brevity comes at the cost of specification rather than being genuinely efficient prose.

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 read-only paginated list tool, the annotations cover safety and the schema covers parameters, so the minimal description is close to sufficient. It still leaves the scope of returned version data and the pagination behavior unmentioned, which an agent calling this tool would benefit from knowing.

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 limit, offset, and project are already fully documented in the schema, including the next_offset pagination hint. The description adds no additional parameter meaning beyond what the schema provides, so the baseline of 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 names the resource (versions/milestones/releases of a project) and clarifies they include shared ones, so the agent knows what is returned. However, there is no explicit verb and no differentiation from sibling listing tools such as list_projects or list_wiki_pages; the agent has to infer 'list' from the tool name. Adequate but vague about scope compared to a fully formed verb+resource statement.

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?

The description gives no when-to-use guidance, no prerequisites, and names no alternative or sibling. The phrase 'of a project' only hints that a project is required, which the schema already enforces. No exclusions or routing advice is present.

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