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

The annotations already declare a safe, read-only, closed-world operation, so the description only needs to add context. It usefully discloses the exact usage dimensions reported (posts written, AI generations, scheduled posts) and that remaining allowance is included, which is valuable since no output schema exists.

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?

A single, front-loaded sentence that contains no filler. It efficiently covers the metric scope and the 'what is left' outcome without unnecessary detail.

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, read-only tool without an output schema, the description sufficiently explains what is returned: usage against allowance plus remaining amounts. It does not specify response formatting, but that is a minor gap given the tool's 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?

With zero parameters, the baseline is 4. The description cannot add parameter meaning, and none is needed for this tool.

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 ('Show'), resource ('workspace's allowance'), scope ('this period'), and the exact metrics covered, so an agent knows it reports usage/quota rather than plan details. It does not explicitly distinguish itself from nearby tools such as get_analytics or get_current_plan, which prevents a perfect score.

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?

There is no explicit when-to-use guidance, no named alternatives, and no exclusions. The purpose implies it is used when checking allowance consumption, but the description provides no routing logic against siblings like get_analytics or get_current_plan.

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