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

Goes beyond the annotations by disclosing the return shape (screens, buttons, fields) and that the tool 'opens nothing by itself', which is a real behavioral detail an agent needs to plan a two-step flow. This is consistent with readOnlyHint=true and destructiveHint=false, though it omits whether the procedure requires specific Brand24 permissions or plan level.

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 two-sentence workflow is front-loaded and useful, but 'from ChatGPT, Claude or any AI agent' is promotional filler and the trailing fragment 'Brand24's official API: Yes.' adds no actionable meaning. Trimming those would sharpen an otherwise compact definition.

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 zero parameters and no output schema, the description carries the burden and does explain conceptually what comes back (a step-by-step Brand24 procedure) and how to act on it. Minor gaps remain around prerequisites and identifying the mention, but the definition is sufficient to select and invoke the tool correctly.

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 baseline is 4. The description correctly does not pretend otherwise, though it also does not explain how the target mention is conveyed to the browser step that follows.

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 ('Change mention sentiment in the user's own Brand24 account') and immediately clarifies that it returns step-by-step guidance rather than performing the change. It does not distinguish itself from sibling Brand24 tools such as brand24_tag_mentions or brand24_list_mentions, so an agent must infer which guidance tool applies to its task.

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?

Explicitly routes the agent: call this to get the procedure, then execute with the cotlet_browser_* tools inside the user's Brand24 Cloud Browser. It gives clear context for the intended workflow but states no exclusions or prerequisites, such as needing an open Cloud Browser session or how to identify the target mention first.

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