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

Annotations already declare readOnlyHint=true and destructiveHint=false with a closed-world scope, so the safety profile is covered. The description usefully adds the 'newest first' sort order, but says nothing about the default page size, whether results are capped or truncated, or what happens when no limit is given.

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, and the ordering constraint sits right where the agent needs it. It is arguably under-specified rather than over-long, but nothing in it is wasteful.

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 read-only list tool with one optional parameter and no output schema, the description covers the essentials of what is returned. It stops short of stating default page size, truncation behavior, or the shape of returned items, which matters given the 50-item maximum.

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% and the single parameter 'limit' has only min/max bounds and no description. The description never mentions 'limit' at all, so it fails to compensate for the coverage gap — an agent cannot tell whether limit means items per page, total items, or how it interacts with the 'newest first' ordering.

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 (drawings in the library) and adds the ordering contract (newest first), which is enough to distinguish it from get_drawing (single item) and create_drawing (write). The verb 'list' is only implied via title/name rather than stated, but the intent is unambiguous.

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 statement of when to use this versus siblings such as get_drawing or status, and no mention of pagination behavior or how to continue past the 50-item cap. The agent is left to infer that this is the browse-all entry point.

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