gdelt_tv_wordcloud

Read-only

Return a frequency-ranked word/label record cloud for a required station and channel (transcript, caption, concept, onscreen_text, or visual). Use the same include/exclude operators and time-window rules as gdelt_tv_search; TV coverage may lag by 24-48 hours. Use gdelt_tv_search for matching clips or gdelt_tv_timeline for airtime volume.

Input Schema

Name	Required	Description
`to`	No	End of an absolute time window. Same formats as from.
`from`	No	Start of an absolute time window. Accepts YYYY-MM-DD, RFC3339, or GDELT's raw YYYYMMDDHHMMSS. Cannot be combined with timespan.
`show`	No	Limit to an exact show name.
`visual`	No	Search visual object/activity labels from computer vision (GDELT's visual: operator), e.g. VOLCANO, POLICE. Repeatable -- multiple values are OR'd together.
`caption`	No	Search human-provided closed captioning (GDELT's cap: operator). Repeatable -- multiple values are OR'd together.
`channel`	Yes	Required. Which match channel to build a word cloud from. Allowed values: transcript, caption, concept, onscreen_text, visual.
`concept`	No	Search Google Knowledge Graph concepts extracted from captioning, by MID code (GDELT's capnlp: operator), e.g. /M/0d063v. Repeatable -- multiple values are OR'd together.
`station`	Yes	Required. Station to search. Allowed values: CNN, MSNBC, FOXNEWS, BBCNEWS, KGO (ABC San Francisco), KPIX (CBS San Francisco), KNTV (NBC San Francisco). See gdelt-tv-stationdetails for GDELT's own current list.
`timespan`	No	Relative time window ending now, e.g. 1h, 7d, 3m, 1y. Cannot be combined with from/to. GDELT's TV archive starts July 6, 2010.
`transcript`	No	Search machine-generated speech-to-text transcripts (GDELT's asr: operator). Repeatable -- multiple values are OR'd together. Short phrases only (GDELT caps each at 5 words).
`day_of_week`	No	Limit to a day of week, 0 (Sunday) through 7 (Saturday), PST.
`onscreen_text`	No	Search OCR'd onscreen text/chyrons (GDELT's ocr: operator). Repeatable -- multiple values are OR'd together. Short phrases only (GDELT caps each at 5 words).
`exclude_visual`	No	Exclude clips whose visual labels match this value (GDELT's -visual: operator). Repeatable; every value must be absent (AND'd exclusions).
`exclude_caption`	No	Exclude clips whose closed captioning matches this value (GDELT's -cap: operator). Repeatable; every value must be absent (AND'd exclusions).
`exclude_concept`	No	Exclude clips whose extracted concepts match this MID code (GDELT's -capnlp: operator). Repeatable; every value must be absent (AND'd exclusions).
`exclude_transcript`	No	Exclude clips whose speech-to-text transcript matches this value (GDELT's -asr: operator). Repeatable; every value must be absent (AND'd exclusions).
`exclude_onscreen_text`	No	Exclude clips whose OCR'd onscreen text matches this value (GDELT's -ocr: operator). Repeatable; every value must be absent (AND'd exclusions).

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds a genuine behavioral caveat beyond the annotations: TV coverage may lag 24-48 hours, and the operator semantics mirror gdelt_tv_search. It stops short of describing return shape or pagination, but the output schema exists.

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 sentences, front-loaded with the core purpose, then behavior, then routing. No filler; every sentence carries distinct 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?

With an output schema present and annotations covering the safety/open-world profile, the description's job is to situate the tool and flag data quirks. It does both, including the coverage lag and cross-tool routing, so nothing material is missing.

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 every parameter including the exclude_* operators, time window rules, and channel values is already documented in the schema. The description restates the channel enum and required station/channel, adding little semantic value beyond the structured data. 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 and output ('frequency-ranked word/label record cloud') plus the two required params and the channel enumeration. It explicitly differentiates itself from gdelt_tv_search (matching clips) and gdelt_tv_timeline (airtime volume), so an agent can place it precisely among its siblings.

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?

Names two alternative tools with the exact condition that selects each: gdelt_tv_search for clips, gdelt_tv_timeline for airtime volume. It also tells the agent to reuse the include/exclude operators and time-window rules of gdelt_tv_search, which is explicit routing guidance.

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