check_budget

Read-onlyIdempotent

Check your current event quota and recorded cost summaries to see if your agent is near its budget limit before proceeding.

Instructions

Read-only hosted event-quota health check. Combines dashboard event quota and recorded cost summaries. This is not SDK BudgetGuard, not a provider invoice cap, and it does not refuse the next model call.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

  "jsonrpc": "2.0",
  "method": "tools/call",

    "name": "check_budget"
  }

A3.9/5.0
Behavior4/5

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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds useful context beyond those annotations, notably that it does not refuse the next model call and that it combines two data sources. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences with no fluff. It front-loads the core purpose and then efficiently adds exclusions that prevent misuse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a no-argument read-only health check, the description provides enough context for correct selection and invocation. It lacks an explicit description of the return format, but this is a minor gap given the tool's simplicity and the absence of an output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so there is no parameter semantic burden on the description. The schema coverage is effectively complete, and no parameter explanation is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as a read-only health check for hosted event quota and states it combines quota and cost summary data. It is specific about what it does, though it does not explicitly distinguish itself from sibling tools like get_usage or get_costs.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for checking hosted event quota health and includes negative guidance (not SDK BudgetGuard, not a provider invoice cap). However, it does not explicitly state when to use this tool over alternatives or name sibling tools as fallbacks.

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