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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: the tool performs no browser action, produces step-by-step UI guidance, and explains why browser automation is required (no official MCP server, API gaps around approving, offering shifts, attesting hours, publishing).

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 behavior (returns instructions, opens nothing) is front-loaded in the second sentence, with the browser handoff immediately after. The closing sentence about Quinyx's REST API is longer than needed and its "checked 22 Oct 2026" date is odd, but it does justify why browser automation is the path.

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 guidance tool with rich annotations and no output schema, the description covers what the agent needs: what it returns, that it is side-effect free, and which tool family to use next. It could go further by specifying the shape of the returned steps or noting whether results are cached, but nothing essential for correct invocation is missing.

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, which sets the baseline at 4; there is nothing for the description to disambiguate. The description correctly implies the scope is fixed to the authenticated user's own account rather than requiring an account or request identifier.

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 names a specific verb and resource ("List approval requests in the user's own Quinyx account") and then explicitly corrects the natural misreading by stating it "Returns how to do it in Quinyx step by step (screens, buttons, fields) and opens nothing by itself." That makes the tool's real output (instructions, not data) unambiguous, though the leading verb "List" still invites the wrong first impression before the correction lands.

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 gives a clear next action: "then do it with the cotlet_browser_* tools in the user's Quinyx Cloud Browser," which tells the agent this is a first step in a two-stage flow. It stops short of naming when not to call it, e.g. that quinyx_approve_request or quinyx_deny_request should be preferred when a direct action tool exists.

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