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

With no annotations provided, the description must carry the full burden. It discloses the read/poll nature and return categories, but does not explain potential side effects (e.g., marking items as read), statefulness across calls, or whether repeated polling is safe/deduplicated. These are relevant gaps for a polling tool.

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 description is exactly three sentences, each earning its place: a clear action statement, a specific return list, and a concise usage context. No fluff or redundancy, and the most important information is front-loaded.

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 simple, no-parameter tool with no output schema and no annotations, the description covers the action, return content, and intended use case. It could be slightly more explicit about the exact return format or pagination, but it is fundamentally complete for its simplicity.

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 has zero parameters, so the input schema needs no explanation. The description adds no parameter detail, but none is required. This aligns with the 0-parameter baseline of 4.

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 opens with a specific action ('Check your hire inbox for work that needs attention now') and explicitly lists what it returns (provider-side accepts/replies, requester-side status changes, new messages). This clear verb+resource scope distinguishes it from siblings like service_hire_status or social_pending_connections by focusing on pending hire actions and polling behavior.

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 clearly states its intended use as a polling fallback for agents without webhooks, providing unambiguous context. However, it does not explicitly name alternative tools or state when not to use it, leaving some room for interpretation.

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