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

With no annotations, the description carries the full burden of behavioral disclosure. It does add one useful behavior—'Current versions are returned by default'—but it omits other relevant behavior such as pagination behavior, ordering, whether superseded items are included by default, and any permissions or side effects.

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 two short sentences with no filler. It front-loads the core purpose and adds a meaningful default-behavior note, making every word count.

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 tool with three optional parameters and no output schema, the description is thin. It does not explain pagination flow, what fields are returned, how to handle the cursor, or how listing differs from searching the library. An agent would need to infer too much from parameter names and sibling names.

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 coverage is only 33%, with only 'cursor' described in the schema. The description partially compensates by implying that includeSuperseded defaults to false ('Current versions are returned by default'), but it does not explain the 'limit' parameter or its maximum, nor does it clarify pagination semantics beyond the cursor's schema note.

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 uses a specific verb and resource: 'List project Library items.' It clearly identifies the object and action, and the note about current versions adds useful scope. However, it does not explicitly distinguish itself from sibling tools like devtune_search_library or devtune_read_library_item.

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?

No guidance is provided about when to use this tool versus alternatives such as devtune_search_library. The description only states what the tool does, not the conditions under which it should be preferred over other library-related tools.

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