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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile needs no further explanation. The description adds the scope of returned data, but since an output schema exists, enumerating return fields adds little beyond what structured data provides; no cost, rate-limit, or auth context is offered.

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 listing the returned items, followed by a short confirming clause. The final sentence is slightly redundant given the empty input schema, but overall the description is economical.

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?

Annotations cover the safety profile, the input schema is empty, and an output schema documents return values, so the description only needs to convey scope — which it does. It could be marginally better by distinguishing itself from the other ops_* integration tools.

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, and the statement 'No parameters required' reinforces rather than contradicts the empty schema. Nothing further is needed on parameter semantics.

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 uses a specific verb ('Show') and enumerates exactly what is returned: plan, trial status, daily tool call usage, integrations, upgrade link. This clearly distinguishes it from most siblings, though it does not explicitly separate 'configured integrations' from the separate ops_list_integrations tool, which is a minor ambiguity.

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?

Usage is only implied — the phrase 'your current plan' suggests a self-diagnostic call, but there is no explicit when-to-use statement and no mention of alternatives such as ops_list_integrations or ops_execution_budget. For a zero-parameter informational tool this is largely self-evident, but the guidance is not stated.

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