The Aggregate — LLM benchmark aggregate

Search models

search_models
Read-onlyIdempotent

Find ranked models by (partial) name or provider. Returns rank, Aggregate Rating and the model page URL. One row per model by default, fused across reasoning-effort settings.

Input Schema

NameRequiredDescriptionDefault
limitNoMax results (1-25, default 10).
queryYesModel or provider name fragment, e.g. "opus" or "deepseek".
include_variantsNoReturn each reasoning-effort variant separately (e.g. "Claude Opus 4.6 (High)") instead of one fused row per model. Default false.

TDQS

A3.8/5.0
Behavior4/5

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

Annotations already declare this a safe read (readOnlyHint=true, idempotentHint=true, destructiveHint=false), so the bar is lower. The description adds real behavioral context beyond them: the returned fields (rank, Aggregate Rating, page URL) and the default de-duplication/fusion across reasoning-effort settings, which explains why a caller may see fewer rows than expected.

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?

Three short sentences, front-loaded with the capability and followed by return shape and the default row behavior. Nothing is repetitive or decorative; every sentence carries information.

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?

With no output schema, the description correctly takes on the return-value burden by naming the returned fields and the one-row-per-model default. It stops short of covering result ordering/pagination specifics, though limit is already documented in the schema.

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%, so the schema already documents query, limit and include_variants. The description reinforces the variant-fusion semantics of include_variants and the partial-match nature of query, but adds no syntax or format detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb and resource plus the matching key (partial name or provider), so the agent knows exactly what comes back: ranked models. It does not name or distinguish itself from siblings like get_model or compare_models, which is the only thing keeping it from a 5.

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?

Usage is implied by the description (search when you have a name/provider fragment), but there is no explicit when-to-use, when-not-to-use, or pointer to an alternative such as get_model for an exact single-model lookup. Minimum viable guidance.

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