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

Annotation Contradiction: readOnlyHint is true, but the description describes activating, installing, publising a challenge, and applying a script—all state-changing actions. An agent relying on the annotation would be misled about whether calling this tool mutates the storefront.

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 roughly 180 words for a zero-parameter menu tool and includes promotional and proof-of-concept detail, such as the exact eqbuilder.dev verification and script ID, that does not help invocation. It is not front-loaded with a direct statement of what the tool does; key caveats are buried in a long paragraph.

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?

It includes some useful caveats—not all 57 widgets are installed, and a workflow start is not a completed install—but the central invocation semantics are muddled. The description does not clearly connect the title's 'Open menu' action to when an agent should invoke this tool, and the read-only annotation contradiction further undermines completeness.

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?

The input schema has zero parameters and 100% coverage, so there is no parameter burden for the description to carry. The baseline for a 0-param tool is 4, and no additional parameter explanation is needed.

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 conveys an identifiable function—browsing/selecting from 57 widgets and installing one—but never clearly says the tool opens a menu or what its own exact verb/resource is. It also mixes in an example proof and cautionary caveats, so the purpose is discernible but not crisp.

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?

It gives useful usage context: call storelayer_recommend first, show the match to the operator, and start installation only after approval. It also states a prerequisite (site-edit authority) and a limitation (EQBuilder cannot edit arbitrary sites), which helps an agent decide when this workflow applies.

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