check_quota

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

With no annotations provided, the description carries the full burden. It discloses cost ($0.0005 USDC) and service provider (ratelord), which are useful behavioral traits. However, it does not mention other aspects like rate limits, permissions needed, or what happens if quota is insufficient, leaving gaps in transparency.

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?

The description is front-loaded and concise, consisting of a single sentence that efficiently conveys the purpose, cost, and service. Every part earns its place without unnecessary details.

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?

Given the complexity of a quota-checking tool with no annotations and no output schema, the description is incomplete. It lacks details on parameter meanings, return values, error handling, and behavioral constraints, making it insufficient for full agent understanding.

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 schema description coverage is 0%, so the description must compensate. It does not explain the parameters (agent_id, api_name, calls_needed) at all, failing to add meaning beyond the bare schema. This is a significant gap given the low coverage.

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 clearly states the tool's purpose with a specific verb ('Check') and resource ('rate limit quota'), and it distinguishes from siblings by specifying the exact function of verifying quota availability before API calls. It also mentions the cost and service provider, adding specificity.

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?

The description provides clear context on when to use this tool ('before making an API call'), but it does not explicitly state when not to use it or name alternatives. It implies usage for pre-checking quota, which is helpful but lacks exclusion criteria or direct sibling comparisons.

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