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

Annotations already declare readOnly, idempotent, non-destructive behavior, and the description is consistent with them while adding real value: it clarifies the URL is opened by the user and the tool writes nothing, plus it discloses the interactive fallback of asking the user to pick a category when none is supplied. It stops short of describing where the URL leads or any auth prerequisites.

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?

Three short sentences, front-loaded with the core action and outcome, with no filler. The write-nothing clause is useful but slightly restates the readOnly annotation, keeping it just shy of a 5.

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, zero-required-parameter tool with an output schema, the description covers the return value, side-effect profile, and the interactive no-category path, so an agent can call it confidently. The only real gap is the undocumented client_class parameter, which is a parameter-level rather than behavioral omission.

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%, so the description must carry parameter meaning. It refers abstractly to a "technology category" (mapping loosely to vertical_id with its enum of tms, dock-scheduling, etc.) but never names the parameter, and it says nothing at all about client_class or its default of "other", leaving half the parameters unexplained.

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 states a specific verb and outcome: it returns a URL the buyer opens to start an assessment for a chosen technology category, and clarifies the tool itself performs no write. This is clearly distinguishable from siblings like list_verticals or my_assessment_status, which do not hand back a launch URL.

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?

Usage context is implied (use it to kick off an assessment in a given category) and it handles the no-category case by prompting the user. However, it never names an alternative or states when NOT to use it (e.g., versus describe_platform or list_verticals to browse categories first), so the agent must infer routing.

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