Country breakdown

query_countries

Read-only

Use this when the user asks how search traffic splits by country. Returns per-country performance (clicks, impressions, CTR, position) over a date range. Country codes are ISO 3166-1 alpha-3. Not for the device split: use query_devices. Rows are sorted by clicks, highest first; ctr is a 0-100 percentage. Quote totals from coverage.siteTotals, or coverage.filteredTotals when coverage.scope is "filtered", not summed rows. Served from the ClickHouse warehouse when available, else the live Search Console API (see dataSource). Date range is optional: omit startDate/endDate to analyze the last 28 settled days (data lags ~2-3 days).

Input Schema

Name	Required	Description	Default
`brand`	No	Optional. Narrow to queries matching the property's branded keywords ('branded') or to all others ('non_branded'). Needs branded keywords set (update_site brandedKeywords); see get_filter_options.
`limit`	No	Rows to return per call (default 100, max 1000).
`offset`	No	Rows to skip. Use pagination.nextOffset from a previous call to get the next page.
`endDate`	No	Optional. Window end as YYYY-MM-DD (e.g. 2026-05-31). You do NOT need to know today's date or the latest available date: omit this and the server uses the latest settled Search Console date (data lags ~2-3 days behind today). Never pass null or the string "null".
`siteUrl`	Yes
`startDate`	No	Optional. Window start as YYYY-MM-DD (e.g. 2026-05-03). You do NOT need to know today's date. Omit BOTH startDate and endDate to analyze the last 28 settled days automatically (Search Console data lags ~2-3 days). Never pass null or the string "null".
`searchType`	No	Search type: web (default), image, video, news (the News tab), discover, googleNews (news.google.com), or all (web + image + video + news + discover combined, position impression-weighted, like the app's "All" filter). Discover and googleNews carry no query dimension, so query-level results for them are empty, and no position: it reads null, not 0.	web
`contentGroupId`	No	Optional. Narrow to pages in this content group (id from get_filter_options or list_content_groups). Groups whose rules cannot be applied as a filter are refused; get_filter_options says which.
`topicClusterId`	No	Optional. Narrow to queries in this topic cluster (id from get_filter_options or list_topic_clusters). Clusters whose keywords cannot be applied as a filter are refused.

Output Schema

Name	Required	Description
`note`	No
`range`	No
`scope`	No
`thenBy`	No
`listKey`	No	Name of the top-level field that holds the rows sortedBy describes.
`siteUrl`	No
`warning`	No
`coverage`	No	How much of the property total the rows cover, totals inline. Quote totals from here; do not sum rows.
`ordering`	No
`sortedBy`	No
`countries`	No
`sortOrder`	No
`thenOrder`	No
`dataSource`	No
`pagination`	No
`partialDays`	No
`dataMaturity`	No
`settledThrough`	No
`coverageUnavailable`	No	Why coverage is null, when it is.
`warehouseLatestDate`	No

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnlyHint, destructiveHint=false, openWorldHint), and the description adds real operational context: row sort order, ctr as a 0-100 percentage, the ClickHouse-vs-live-API fallback surfaced via `dataSource`, and the data lag. It also warns not to sum rows but to quote `coverage.siteTotals`/`coverage.filteredTotals` depending on `coverage.scope`, though it could be clearer about what happens when a filter narrows the scope.

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?

Six sentences, each carrying distinct information (trigger, return fields, exclusion, sort/format, totals caveat, data source/lag). The trigger and the sibling exclusion are front-loaded where an agent will read them first.

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 an output schema present the description needn't explain return shapes, yet it usefully flags the coverage totals pitfall and the data source field. For a 9-parameter read tool with 89% schema coverage this is nearly complete; only the filter parameters (brand, contentGroupId, topicClusterId) go unmentioned in the description.

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 89%, so the schema already documents the date defaults, limit/offset, searchType enums and filter ids in detail. The description reinforces the date-range default and ISO alpha-3 country codes, but adds little that isn't already in 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.

Purpose5/5

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

States a specific verb+resource ('how search traffic splits by country') and enumerates the metrics returned (clicks, impressions, CTR, position). It explicitly names the sibling it is not for ('Not for the device split: use query_devices'), so the agent can disambiguate without opening either 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?

Gives the triggering user question verbatim, names the exclusion and the alternative tool (query_devices), and explains the date-range default (omit both dates → last 28 settled days, ~2-3 day lag). Nothing about when to select this tool is left to inference.

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