create_rate_alert

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

No annotations are provided, so the description carries the burden of disclosing behavior. It does disclose the plan requirement and the alert delivery mechanism, but omits other relevant traits such as the response shape, whether repeated calls create duplicate alerts, or whether it consumes API quota. It is adequate but incomplete.

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 two sentences with no filler. The core purpose ('Create a rate alert') is front-loaded, followed by the condition and plan requirement. Every phrase earns its place.

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 mutation tool with no output schema and no annotations, the description should ideally mention what the call returns (e.g., alert ID) or how to verify creation. It covers the plan prerequisite and basic alert behavior, but the missing return-value information leaves an agent without full guidance. The schema handles parameter documentation, so this is mostly a functional-completeness gap.

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 input schema already describes all five parameters with 100% coverage, so the baseline is 3. The description adds no extra parameter-level meaning; it references 'pair' and 'threshold' but does not elaborate on syntax, units, or formats beyond what the schema provides.

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 creates a rate alert, including the notification mechanism (email and optional webhook) and the trigger condition (when a pair crosses a threshold). This distinguishes it from sibling tools like list_rate_alerts and delete_rate_alert, which are read/delete operations, and from rate querying tools like get_pair_rate.

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 useful context: it fires on threshold crossing and requires a Business plan or higher. However, it does not explicitly name alternatives or situations where one would prefer another tool, and does not offer when-not-to-use guidance. The usage is implied rather than direct.

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