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 by stating the tool 'opens nothing by itself'. That is a real behavioral disclosure beyond the annotations: it prevents the agent from assuming the approval is performed. It adds the return shape (screens, buttons, fields) but says nothing about failure modes or what happens if the user is not logged in.

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 content is two efficient sentences with the 'returns steps, does nothing' point front-loaded. The closing line about Bizneo's REST API ('checked 22 Oct 2026') is unrelated to invoking this tool and consumes space without helping the agent decide or call. Trimming that would make the definition tight.

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 no-parameter, no-output-schema guide tool, the description covers what it produces and how it fits into the browser workflow, which is what an agent needs to act. The remaining gap is the unaddressed question of how the target request is scoped with zero inputs, plus the extraneous API-status sentence.

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 the schema carries no semantics to supplement and the baseline is 4. The description does not address the absence: it never explains how the specific remote work request is identified without any input, which is a notable omission for an 'approve' action even if the answer is that the guide is generic.

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 specifies verb and resource (approve a remote work request in Bizneo) and, critically, corrects the misleading title by stating it 'Returns how to do it in Bizneo step by step (screens, buttons, fields)'. That reframes the tool as a guide generator rather than an executor, which an agent needs. It is slightly self-correcting rather than front-loaded, so the agent must read past the name to learn what actually happens.

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?

Explicit handoff is given: use this to get steps, 'then do it with the cotlet_browser_* tools in the user's Bizneo Cloud Browser'. That tells the agent this is the first half of a two-step workflow. It does not name when to skip it (e.g., an alternative direct-action path), but no sibling offers the same action, so the guidance is adequate.

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