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

The annotations (readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=false) already declare a safe, side-effect-free read, and the description is consistent with them while adding real value: it describes the return content (step-by-step screens, buttons, fields), states it opens nothing, and names the tool family required to actually execute. It omits whether a Gladly tab must already be open in the browser context before the follow-up calls.

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 essential information (what it returns, that it does nothing itself, and which tools to use next) is front-loaded and clear. The closing sentence about Gladly's REST API and the absence of an official MCP server is tangential to invoking this tool, and the 'checked 20 Oct 2026' date is noise, but neither is disruptive.

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 parameters, no output schema, and rich annotations, the description supplies nearly everything an agent needs: the return shape, the non-executing behavior, and the browser-tool handoff. The only gap is the prerequisite state of the browser/Gladly session needed for the subsequent cotlet_browser_* calls.

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 add and the schema is fully self-describing. Nothing in the description contradicts or muddies the empty input contract.

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 resource (Gladly topics) and, crucially, clarifies that the tool does not perform the action itself: it 'Returns how to do it in Gladly step by step (screens, buttons, fields) and opens nothing by itself.' That resolves the otherwise misleading name. It does not distinguish itself from the other gladly_* siblings (add_note, assign_conversation, etc.), which is the only reason it falls 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 clearly routes the agent: use this to get the procedure, then 'do it with the cotlet_browser_* tools in the user's Gladly Cloud Browser.' That is explicit guidance on the follow-on alternative and the condition for using it. It does not say when to prefer this over other Gladly guidance tools, but the core use/next-step contract is clear.

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