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

Annotations already declare this a read-only, idempotent, non-destructive operation, so the description only needs to add context. It does add the non-obvious behaviors that it returns the last ten versions and accepts an optional version cursor, but it is silent on cursor semantics (does it page further back? what happens at the end?) and on what occurs when neither identifier is supplied.

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 front-loaded sentence with no filler. The result scope (project plus last ten versions) and the cursor come first, which is the information an agent most needs before calling.

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?

With no output schema, no parameter descriptions, and three identifier/cursor parameters that are all optional, the description is not complete enough. It never resolves which identifier to pass or how the returned version list is truncated, both of which an agent needs to call this correctly.

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% across three parameters, so the description carries the full burden and largely fails it. It clarifies only that versionsCursor is optional; the slug vs projectId distinction and the fact that zero parameters are required (which identifier is needed for a lookup) are left entirely unaddressed.

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?

States a specific verb (read) and resource (one visible project plus its last ten versions), and the scope detail 'visible' plus the version-list side effect separates it from list_projects and get_account. An agent can distinguish this from its siblings without opening a schema.

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 explicit when-to-use or when-not-to-use guidance and no alternative tool is named. The phrase 'visible project' hints at an access constraint but never states the condition that selects this tool over list_projects or get_account.

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