Arena trap data

forge_traps
Read-onlyIdempotent

Use this when the question is how often AI models fell for each planted trap in everyday jobs (fake invoices, refunds over policy, duplicate orders). Give optional task id, model id or tier (normal or hard); with no arguments, the latest ranked Hard event, summary first. Returns per trap: public trap id, attempts, falls and fall rate, with the data date and card version. Pass rates per model and job: arena_results.

Input Schema

taskNoOne Arena task; all tasks of the tier if omitted
tierNonormal or hard (normal when only a model is given); a task id sets its own tier; no arguments at all gives the latest ranked Hard event
modelNoOne model id; all models if omitted

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, closed-world and non-destructive, so the safety profile is covered. The description adds genuinely new behavior: the zero-argument default resolves to the latest ranked Hard event with the summary first, plus the returned fields (public trap id, attempts, falls, fall rate, data date, card version). It stops short of covering pagination or ordering across multiple traps, which keeps it from a 5.

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

Conciseness4/5

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

Two dense sentences, front-loaded with the trigger condition, then filtering, then return fields. The field enumeration is slightly list-like but every clause carries information an agent needs.

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

Completeness5/5

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

An output schema exists, so return values needn't be fully explained, and annotations carry the safety profile. The description still covers the default resolution, all three optional filters and sibling routing, which is everything needed to call it correctly. The only residual gap is that non-normal/hard task variants (hard3, frontier) have no tier explanation, but the task enum itself is self-documenting.

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 description coverage is 100% and the schema already documents task, tier and model, including the precedence rules ('a task id sets its own tier', 'normal when only a model is given'). The description restates those same interactions rather than adding new meaning, so the baseline 3 applies.

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 states a concrete verb and resource: 'how often AI models fell for each planted trap' and names the actual trap categories (fake invoices, refunds over policy, duplicate orders). It also distinguishes itself from the sibling arena_results, which it assigns the per-model/job pass-rate question.

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

Usage Guidelines5/5

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

'Use this when the question is how often AI models fell for each planted trap' gives an explicit trigger condition, and 'Pass rates per model and job: arena_results' names the alternative and the case that selects it. The no-argument default behavior is also spelled out, leaving nothing to inference.

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