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 reinforces this by stating it 'opens nothing by itself' — a meaningful disclosure that no side effect occurs. It also discloses the return content type (step-by-step screens/buttons/fields) and the required follow-up tooling. What it omits is whether the guidance is static or fetched live.

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 follow-up workflow are front-loaded and useful, but the trailing sentence about Officient having an API but no official MCP server (with a checked date) reads as provenance/marketing filler that does not help an agent select or invoke the tool. The middle clause about cotlet_browser_* tools could be tightened.

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 and no output schema, the description carries the burden of explaining what comes back, which it does (step-by-step instructions). It also explains the execution path via browser tools. Complete enough for an agent to call it correctly, with only minor gaps around how current the instructions are.

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 baseline is 4. Nothing in the description conflicts with the empty schema, and no parameter explanation is needed.

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 pairs a specific verb and resource (request time off in Officient) with the crucial clarification that the tool only returns step-by-step instructions (screens, buttons, fields) rather than performing the action. This resolves the ambiguity created by the mutating-sounding name. It does not explicitly distinguish itself from cotlet_app_guide, but the Officient-specific framing makes its scope clear.

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 workflow: call this tool to get instructions, then execute with the cotlet_browser_* tools in the user's Officient Cloud Browser. The condition for use (need Officient-specific steps) is implied well enough to act on. It does not state when not to use it or how it relates to cotlet_app_guide.

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