nexalayer_get_budget

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds the useful detail that the payload includes pause state and next daily reset timing, but says nothing about auth requirements, rate limits, or freshness of the spend figure.

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 with no filler; every listed item (limits, spend, pause state, reset) is meaningful content rather than restated metadata.

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 full annotation coverage, the description is nearly sufficient, and since no output schema exists, enumerating the returned fields is genuinely valuable. It stops short of explaining reset cadence/format or whether the read is account- or workspace-scoped.

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 zero parameters, so the baseline of 4 applies. The description correctly avoids inventing parameter semantics and instead spends its words on the returned fields.

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 enumerates the exact resource contents returned: spend limits, current spend, pause state, and next daily reset. This clearly separates it from nexalayer_get_balance, but the description never names or contrasts a sibling, so differentiation is left to inference.

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 statement of when to call this versus nexalayer_get_balance, nexalayer_set_budget, or nexalayer_usage_alerts, and no prerequisites or exclusions are given. An agent must infer usage purely from the resource list.

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