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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuine context beyond that — ordering (newest first), workspace scoping, and that each item carries an editor link. However, it says nothing about pagination or how the 'latest' set is bounded by the limit parameter, leaving a behavioral gap.

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 sentence that front-loads the resource and workspace scope, then appends ordering and return contents. No filler; every clause carries information.

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, the description compensates well by describing what each returned item contains (an editor link). With only one optional parameter and read-only annotations, this is nearly complete; a note on pagination/limit behavior would close the remaining gap.

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 100% with a single optional limit parameter (1-50, default 20) fully documented in the schema. The description's 'latest' hints at recency but adds no syntax or meaning beyond the schema, so the baseline 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 precisely ('the member's latest Creadal designs in the connected workspace'), states ordering (newest first), and describes the return shape (a link to open each in the editor). It is clearly distinguishable from siblings such as list_templates, list_themes, and get_design, though the list verb itself is only implied.

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 guidance, no exclusions, and no pointer to alternatives like get_design for a single design or list_templates for reusable templates. The agent must infer from the resource name alone that this is the browse-my-designs entry point.

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