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

Annotations already declare readOnlyHint=true, openWorldHint=false, destructiveHint=false, so the safety profile is covered. The description goes beyond that by disclosing what the tool actually returns (wizard explanation, post-submission behavior, direct link), which is proprietary content rather than restated structured data. It stops short of describing output format or length, so not a 5.

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?

Two sentences, both earning their place: the first front-loads what the tool produces, the second carries scope and the sibling routing rule. No filler, no repetition of the title.

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?

No output schema and no parameters, so the description must carry the burden — and it does, by telling the agent what content it will yield and where the boundary with start_project lies. Nothing needed for correct invocation is missing.

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?

Zero parameters, so the baseline is 4 per the rubric. Nothing in the description is needed to clarify inputs, and it correctly implies this is a no-argument informational call.

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?

States a specific verb+resource ('Explains how getting quotes ... works') and enumerates the substantive content: the free project-submission wizard, post-submission flow, and the direct link. It also names the sibling it is not (start_project), so the agent can disambiguate immediately.

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?

Gives explicit when-to-use (general how-does-it-work questions, scoped to Chicago area / Northwest Indiana / Southern Wisconsin) and explicit when-not-to-use with the alternative ('when the user has already described a specific project, use start_project instead'). This is a model routing rule, not an inference.

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