Tako: Search

tako_search
Read-onlyIdempotent

Search Tako's data graph and the live web in one call: many results at once, as structured cards plus web results, with the top card rendered inline as a chart.

It finds data; tako_contents fetches it. Each card carries a headline value, node ids, and a url — pass the url to tako_contents for rows (exportable: true cards) or a web result's full page text. When exportable is false the rows are locked — read the headline value from the card's description.

Best for: breadth — fan out several narrow queries in parallel. Each query resolves one metric — for one entity, or a comparison set ("Apple revenue", "Nvidia vs AMD gross margin"); several metrics or topics in one query retrieve poorly. To learn what Tako covers, or a metric's canonical name, run tako_available_data first, then search on the canonical name it returns.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
queryYesNatural-language search query (e.g. "US GDP growth", "Intel vs Nvidia revenue"). Double-quote a multi-word name to keep it one entity ("tesla motors" club revenue); an unpaired quote disables quoting. Website-traffic data is keyed by domain — query "openai.com monthly visits", not "OpenAI website visits".
localeNoBCP-47 locale tag for language and formatting. Omit it and the server uses en-US. Set it to localize for the user.
sourcesNoWhich corpora to search; default is both. Narrow to ["data"] once `tako_available_data` confirms coverage; narrow to ["web"] only for news or page text — website traffic is in the data graph.
country_codeNoISO 3166-1 alpha-2 country code for localized results. Omit it and the server uses US. Set it to localize for the user.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
cardsYesThe data cards. Fetch an exportable card's rows with tako_contents on its url.
usageYesCost-plus usage for this request (null when not metered).
guidanceNoZero-card responses only: what this response is evidence about, and the one next action.
web_resultsYesWeb results.
source_notesNoWhat each source is and how it builds its data, keyed by source name.
metric_definitionsNoWhat each metric means (unit, basis, caveats), keyed by metric name, deduped across cards.

TDQS

A5/5.0
Behavior5/5

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

Annotations (readOnlyHint, openWorldHint, idempotentHint) already establish safety, and the description adds meaningful behavioral detail: exportable true/false row-locking behavior, direct instruction to read headline value from card.description when locked, and the top-card chart rendering. These are not visible in annotations or schema, and nothing contradicts the annotations.

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 front-loaded with the core action, then progresses to result interpretation, best-for usage, and setup steps. Every paragraph serves a distinct purpose with no filler or redundancy, and the length is justified by 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 an output schema exists and annotations cover the safety profile, the description covers the remaining needed context: how to interpret cards, when rows are locked, and how to chain with `tako_contents` and `tako_available_data`. No critical guidance gap remains for selecting and invoking the tool correctly.

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

Parameters5/5

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

Schema description coverage is 100%, so the baseline is 3, but the description adds substantial guidance beyond the schema: it explains query strategy ('Each query resolves one metric'), recommends using canonical names from `tako_available_data`, and describes when to narrow sources (web only for news/page text, website traffic is in data graph). This meaningfully improves correct invocation.

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 action ('Search Tako's data graph and the live web') and describes the result shape (structured cards plus web results, top card rendered as chart). It explicitly differentiates from siblings by noting 'It finds data; `tako_contents` fetches it,' so an agent can distinguish it without opening other tool definitions.

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?

Provides explicit when-to-use guidance: 'Best for: breadth — fan out several narrow queries in parallel' and warns against combining several metrics in one query. It also routes to `tako_available_data` for canonical names and to `tako_contents` for fetching, naming alternatives and conditions clearly.

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