trends___get_time_series

Read-onlyIdempotent

Full historical series for one keyword and one source (0-100 values, plus volume when available). Suited for charting or custom math. Live 'what's trending now' boards are on get_top_trends. get_growth answers most growth questions with less data. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior. The description adds valuable behavioral context beyond those: it discloses that a plan-limit message is returned when rate limited or when the monthly quota is exhausted, and it describes the return values (0-100 plus volume). It does not cover authentication or any series-length/pagination behavior, leaving a minor gap.

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?

The description is four sentences with zero waste: purpose first, then usage alternatives, then rate-limit behavior. It is front-loaded and appropriately sized for the tool's complexity.

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?

Given the rich 100%-covered input schema and the absence of an output schema, the description is complete enough for correct invocation. It covers return format, rate-limit/quota behavior, and sibling alternatives, while the schema handles source-specific keyword formats and optional filters.

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 provides detailed parameter semantics for keyword, source, country, language, and resolution. The description only reinforces the one-keyword/one-source constraint and does not add syntax or conditional rules beyond what the schema already states.

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 specific verb and resource: 'Full historical series for one keyword and one source', and it clarifies the return shape (0-100 values, plus volume). It explicitly distinguishes itself from get_top_trends and get_growth, so an agent can identify its role without opening the schema.

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?

It names the alternative for live 'what's trending now' boards (get_top_trends) and the alternative for most growth questions (get_growth), making the routing conditions explicit. This is exactly the when-to-use-this-vs-alternatives guidance needed.

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