intelligence_assess_risk

Assess fraud risk for a phone number by receiving a score from 0 to 1000 and a recommendation to allow, flag, or block the transaction.

Instructions

Get fraud risk score (0-1000) for a phone number. Returns recommendation: allow/flag/block. See docs://telesign/intelligence for score interpretation.

Behavior3/5

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

No annotations exist, so the description must disclose all behavioral traits. It mentions the output (score and recommendation) but lacks details on error handling, rate limits, prerequisite authentication, or what happens with invalid input.

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?

Two sentences, front-loaded with purpose. No extraneous information. Every sentence earns its place.

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 simple risk assessment tool with no output schema, the description explains the return values (score and recommendation) and points to docs for interpretation. It could mention error handling or rate limits but is reasonably complete.

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

Parameters3/5

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

Schema coverage is 100%, so baseline is 3. The description does not add meaning beyond the schema; it only references the phone number without additional context on the other parameters.

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

Purpose5/5

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

The description clearly states it gets a fraud risk score for a phone number with a specific range (0-1000) and returns a recommendation (allow/flag/block). This is distinct from sibling tools like phoneid, verifyapi, messaging, and docs.

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?

No explicit guidance on when to use this tool vs alternatives, though it's the only risk assessment tool among siblings. A pointer to external documentation is provided but no when/why context.

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