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

The description preempts the biggest misread an "update" name would otherwise create by stating flatly that it "opens nothing by itself" and only returns screens, buttons and fields. That is fully consistent with readOnlyHint=true, idempotentHint=true and destructiveHint=false, and it adds return-content detail the annotations cannot convey.

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 front-loaded sentences that move from what it does, to what it returns, to what to run next. The closing note on the official API is mildly tangential but short enough to earn its place as context for why browser automation is needed.

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 guidance tool with no output schema, the definition covers purpose, return content, and follow-up action adequately. It does not explain how the walkthrough targets a specific client form given there are no inputs, which is a small 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?

Zero parameters and 100% schema coverage, so there is nothing to document and the baseline applies. The description adds the useful note that the response is narrative guidance rather than structured data.

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 and resource ("Update client form response") and immediately clarifies that the tool does not perform the update itself but returns step-by-step instructions. That reframing disambiguates it from true mutation siblings like paired_plus_send_client_form, though it never explicitly names a sibling to route to.

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 concrete next-step guidance: call this to get the walkthrough, then execute with cotlet_browser_* tools in the Paired Plus Cloud Browser. It also explains why the browser route is required (no self-serve API key found). It stops short of stating when a caller should prefer this over a fully automated sibling.

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