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

Annotations declare readOnlyHint=true and destructiveHint=false, which would superficially look contradictory for an "approve" tool; the description pre-empts that by explicitly saying it "opens nothing by itself" and only returns guidance. It also discloses the handoff mechanism (cotlet_browser_* in the user's own browser session), which is behavior an agent could not infer from annotations alone.

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 purpose and the browser handoff are front-loaded and useful, but two clauses earn little: "from ChatGPT, Claude or any AI agent" adds no selection value, and the "Officient has an API but no official MCP server (checked 22 Oct 2026)" note is metadata rather than invocation guidance.

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 advisory tool with no output schema, the description covers what it returns, what it does not do, and how the agent should complete the action. The one missing piece is what the returned steps look like or how the target absence request is conveyed, but the essential workflow is complete.

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 and there is nothing for the description to disambiguate at the parameter level. A minor gap remains: nothing explains how the absence request is identified if no input is accepted, but with an empty schema that is inherent rather than a description failure.

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 absence request") scoped to the user's own Officient account, and immediately clarifies the tool's actual nature: it returns step-by-step instructions rather than performing the approval. That distinguishes it from both the sibling officient_* data tools and the cotlet_browser_* action tools without needing the schema.

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?

Gives clear sequencing guidance: call this to get the screens/buttons/fields, then execute with cotlet_browser_* in the Officient Cloud Browser. It does not state exclusions (e.g., what to do if the user just wants to see absences, which would be officient_list_colleague_absences), so it stops short of full when-not guidance.

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