Get Pulse Verity Account Status

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

Goes well beyond the readOnly/idempotent annotations: the monthly allowance is account-wide across keys and apps, perMinute applies per key, the call does not consume allowance, and the key itself is never returned. Those are exactly the semantics an agent needs before reasoning about quota state, and none are visible in the annotations.

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?

Front-loaded with purpose, then quota semantics, then auth. The field enumeration is somewhat dense and partially redundant with the output schema, but it is compact and every sentence carries new information. Minor trimming of the field list would make it tighter.

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 tool with an output schema, the description covers scope, quota accounting rules, cost of the call, and authentication. Nothing an agent needs in order to call it correctly or interpret the response is 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?

Zero parameters, so there is nothing to disambiguate and the baseline of 4 applies. The description usefully explains that the key is supplied via PULSE_API_KEY environment/host configuration rather than as a parameter, which reinforces why the schema is empty.

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 (read) and resource (this developer key's Pulse Verity plan and usage) and even gives the endpoint path /api/index/v1/account. Nothing in the sibling list (price, batch, assets, print, history, feedback) overlaps with an account/quota read, so an agent can route here unambiguously.

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?

It makes the use case implicit but clear: check plan, remaining quota, per-key rate and batch limits. It also states prerequisites ('Needs a developer key (PULSE_API_KEY) or the hosted server') and that the call is free of charge. It does not explicitly name alternative tools or when-not-to-use, which keeps it below a 5.

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