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

Beyond the annotations, the description discloses the single most important behavioral trait: this tool opens nothing by itself and only returns instructions, so the agent must chain into cotlet_browser_* to actually act. It also specifies what the returned guidance contains (screens, buttons, fields) and confirms scope to the user's own account. This is exactly the kind of chaining and side-effect disclosure annotations cannot express.

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?

Three sentences, front-loaded with the action and followed by the critical 'opens nothing by itself' caveat. Minor wasted space in 'from ChatGPT, Claude or any AI agent' and the parenthetical API-check date, neither of which changes how an agent invokes the tool.

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 and does so: it explains the return content (step-by-step screens, buttons, fields), states the absence of side effects, and names the follow-up tool family. Remaining ambiguity — how the absence list is scoped or filtered, and what to do if the user lacks permission to view colleague absences — is minor for a zero-argument guide tool.

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 score of 4 applies and the description has no parameter meaning to add or omit. The empty schema is consistent with a guide-style tool that needs no arguments.

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 states a specific verb and resource (list colleague absences in Officient) and labels the domain as the user's own Officient account. It falls short of a 5 because the opening line suggests it retrieves absence data, while the second sentence reveals it actually returns step-by-step instructions for doing it in Officient — the agent must read past the first sentence to learn the real output. Sibling differentiation is only partial: officient_list_colleagues is a close name, but the 'absences' qualifier does most of the separating work.

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?

The description gives a clear execution path: call this tool, then perform the action with cotlet_browser_* tools in the user's Officient Cloud Browser. It also explains why this route exists (Officient has an API but no official MCP server), which helps the agent understand this is the intended access pattern rather than a workaround. It does not explicitly say when to choose a different sibling (for example, officient_request_time_off or officient_approve_absence_request), so it stops short of a 5.

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