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

Annotations declare readOnlyHint=true and destructiveHint=false, and the description is consistent: it says it opens nothing and returns instructions instead of acting. It adds context beyond annotations, explaining that Connecteam's official MCP server cannot act on the account and the REST API needs Expert plan or higher, which explains why the browser fallback exists.

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 behavior and the handoff to cotlet_browser_* tools are front-loaded in the first sentence, which is good. The trailing note about Connecteam's REST API plans and official MCP server is background justification that is somewhat verbose for a tool description and dilutes the actionable content.

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 tool with no output schema, the description covers what the tool returns (step-by-step screens, buttons, fields) and what it does not do (open anything). It lacks any hint about how the agent should locate the target request before invoking the browser steps, which is the main remaining gap.

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?

Zero input parameters, so there is no schema semantics to compensate for; baseline 4 applies. The description is silent on how the specific request to approve is identified, but no parameter exists to carry that, so nothing is left misdocumented.

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 ("Approve time off request in Connecteam") and immediately clarifies the real mechanic: it returns step-by-step instructions rather than performing the approval. That distinguishes it from connecteam_approve_timesheet, though it never names that sibling explicitly.

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 tells the agent what to do next: "opens nothing by itself; then do it with the cotlet_browser_* tools in the user's Connecteam Cloud Browser." That is a clear usage path. It stops short of stating when to prefer this over a direct browser flow without this guide.

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