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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, and the description is consistent with them, explicitly stating it 'opens nothing by itself'. It adds useful context beyond the annotations: what the response contains (screens, buttons, fields) and the follow-up execution path. The note about FreeScout's API being gated behind a paid module further explains why browser automation is required.

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 core behavior and follow-up path are front-loaded in the first sentence, which is good. However, the trailing sentence about FreeScout's official REST API, the paid API & Webhooks module and the 'checked 23 Oct 2026' verification date is justification narrative that does not help an agent select or invoke the tool, and the second sentence is a long run-on mixing several ideas.

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?

With no input schema and no output schema, the description carries the burden of describing the return value, and it does so ('step by step (screens, buttons, fields)'). Combined with the execution handoff to cotlet_browser_*, an agent has enough to call it correctly. Only minor gaps remain, such as whether the guidance is app-specific or conversation-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 there is no parameter meaning to convey and the baseline is 4. The description correctly implies no input is needed, since the target is 'the user's own FreeScout account'.

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 makes clear this does not perform the action: it 'Returns how to do it in FreeScout step by step (screens, buttons, fields) and opens nothing by itself'. That disambiguates the misleadingly action-oriented name and points to the cotlet_browser_* tools as the execution path. It stops short of naming which sibling guide tools (e.g. cotlet_app_guide) to prefer, so it is clear but not sibling-differentiated.

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 a concrete usage pattern: call this to get the step-by-step procedure, then carry it out with the cotlet_browser_* tools in the FreeScout Cloud Browser. That is clear context for when to use it. There is no explicit when-not or a named alternative for cases where a direct API-based FreeScout tool exists, so it falls short of full routing guidance.

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