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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile needs no restating. The description adds that results are id/name/state tuples, but says nothing about pagination, ordering, or whether the list is company-scoped beyond "the company's".

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 short fragments, zero filler, with the return fields and the follow-up tool front-loaded. Slightly telegraphese, but every clause earns its place.

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 no-param, read-only list tool with annotations covering safety and no output schema, the description supplies enough: what comes back, where it comes from, and what to do with the ids. Only pagination/size expectations are missing.

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 no parameters, so the baseline is 4; the description correctly signals a parameterless list call rather than implying hidden filters.

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?

Names the resource (company overtime rules) and enumerates the returned fields (id, name, state), plus the endpoint GET /v1/OvertimeRules. The verb is only implied by the tool name/title, but the scope is unambiguous and no sibling tool covers overtime rules.

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?

"Use the ids with bilflo_update_contract_job" gives concrete downstream usage, which is genuinely helpful. However, it never states when an agent needs overtime rules or that there is no filtering/parameter variant; usage is implied rather than framed as a when/when-not decision.

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