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

The description adds real context beyond the annotations: it 'opens nothing by itself' and returns screens/buttons/fields guidance, consistent with readOnlyHint=true and openWorldHint=false. The API-availability note explains why no direct API path exists. However, it says little about the shape of the returned guidance (length, whether it varies by plan/location, what happens if settings are already configured), so behavioral disclosure is useful but incomplete.

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 purpose and the execute-via-browser handoff are front-loaded, which is good. The closing research note about 404 URLs with a hard-coded date is lengthy and will age poorly; it justifies the design but is detail the agent rarely needs in full.

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 zero-parameter, read-only, no-output-schema guidance tool, the description covers what the agent needs: what it returns, that it performs no mutation, and which tools do the actual work. Minor gap: no guidance on whether the returned steps are account-, location-, or plan-specific.

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 tool takes zero parameters, so the schema carries no semantics to explain and the baseline of 4 applies. The description correctly implies no inputs are required, though it could have noted that no account/location targeting parameter 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 names the specific resource (booking settings and booking forms) and, after an initial framing that sounds like it performs the configuration, clarifies that it actually returns step-by-step instructions. The sibling set confirms booking settings/forms is a distinct configuration area. It does not explicitly differentiate this from near-neighbors such as member sign-up forms or lead forms, which keeps it short of a 5.

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 states the usage pattern clearly: call this to get the Gymdesk UI walkthrough, then perform the change with the cotlet_browser_* tools. That is a concrete when-to-use workflow. It stops short of a 5 because it gives no exclusions or disambiguation against related configuration/form siblings that an agent might pick instead.

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