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

Adds context beyond the annotations: the data comes from a read-only OData warehouse refreshed nightly, so today's entries may lag until tomorrow — a real caveat an agent would otherwise not know. Missing any statement about response size limits or failure behavior, but the freshness warning is the key disclosure.

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?

One tight paragraph, purpose front-loaded, followed by filters, data-source caveat, pagination, and endpoint. No redundant or throwaway sentences.

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?

No output schema exists, but the description enumerates the returned fields, explains the pagination contract (next_skip), and flags data latency. That is everything an agent needs to call it correctly and interpret the results.

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?

Schema coverage is 100%, so every parameter is already documented in the schema. The description restates the filter dimensions but adds no format or behavioral detail beyond what the schema provides, so baseline 3 applies.

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 ('List time off requests') and enumerates the row fields returned (employee, plan, dates, hours, status, comments, manager), which clearly separates it from the sibling balance/approval list tools. An agent can identify what it retrieves without opening 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 concrete conditions — filter by status, person, or start-date range — and explains pagination via skip/next_skip. It does not name an alternative (e.g., exaktime_query_odata) for ad-hoc queries, so this lands just 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.
