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

Crucially discloses that the tool 'opens nothing by itself' and only returns instructions, which reconciles the alarming 'delete and block' name with the readOnlyHint=true / destructiveHint=false annotations. It also notes the actual mutation happens via browser tools, giving the agent the full picture beyond the annotations.

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 purpose and the 'returns instructions, opens nothing' clarification are front-loaded and valuable. However, the trailing fragment 'Brand24's official API: Yes' is cryptic and ambiguous, and the crowded semicolon-separated structure makes the sentence harder to parse than necessary.

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, no-output-schema tool whose annotations cover the safety profile, the description covers what it returns (step-by-step instructions) and the follow-up execution path. It could be slightly more explicit about the format of the returned guidance, but the essential information is present.

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 no parameters, so there is no schema semantics to add; baseline applies. The description does not introduce undocumented inputs or hidden configuration.

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 action on a specific resource ('Delete and block mentions in the user's own Brand24 account') and immediately clarifies that it returns step-by-step instructions rather than performing the action. This lets an agent distinguish it from the cotlet_browser_* tools that actually execute the deletion.

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?

Provides a clear workflow: call this first to get the screens/buttons/fields, then perform the action with cotlet_browser_* tools in the user's Brand24 Cloud Browser. It does not, however, contrast against sibling brand24_* mention tools (e.g. tag_mentions, change_mention_sentiment), so the agent must infer which mention operations belong here.

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