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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, and the description is consistent with them. Beyond the annotations it adds the non-obvious behavior that the tool only returns procedural guidance and performs no action itself, plus the API-key prerequisite context that explains why browser automation is the path. It stops short of describing the shape or granularity of the returned steps.

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 critical mechanic (returns instructions, opens nothing) is placed mid-sentence after a long clause, and 'from ChatGPT, Claude or any AI agent' is marketing filler that does not help an agent decide. The closing note on API key provisioning is relevant but reads as an aside bolted onto the end.

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 annotations already covering the safety profile, the remaining burden is explaining the unusual guide-then-browser workflow, which the description does. What is missing is any indication of what the returned step-by-step content looks like or how much detail to expect before handing off to the browser tools.

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; the baseline for a parameterless tool applies. The description correctly implies no inputs are needed to obtain the guidance.

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 definition names a specific verb and resource (list activities in the user's Recruiterflow account) and then clarifies the real mechanic: it returns step-by-step instructions rather than activity data, and 'opens nothing by itself.' That correction is essential, though the leading sentence still reads like a data-returning list tool, creating a brief mismatch an agent must reconcile. It does not explicitly differentiate from sibling list tools such as recruiterflow_list_candidates.

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 tells the agent what to do next ('then do it with the cotlet_browser_* tools in the user's Recruiterflow Cloud Browser'), which is genuine routing guidance. However, it gives no when-not-to-use conditions and no explicit comparison against the other recruiterflow_list_* siblings, so the choice among them is left to inference.

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