Read references/tiangong-data-requirement.json.
Use the caller- or workspace-resolved stable CLI. The requirement declares compatible capability and operation contract majors; it does not select a package build.
Run data describe with that same CLI. Continue only when the capability ID and required contract majors match, and copy the exact current capability/operation versions from that response into the run request.
Immediately inspect manifest.availability and discovery.availability. If either does not report available, stop before constructing a request and report its exact reasonCode, description, and resume criteria. Do not bypass suspension with a direct provider request. Route to GDELT Web NGrams only when the caller accepts its different literal phrase-search semantics.

tiangong-ai data describe gdelt.doc-search --json

Use the returned Discovery Metadata to confirm current source coverage, freshness, restrictions, provides, and doesNotProvide. Do not substitute facts remembered from an older Skill revision.

Prepare the request

Build a tiangong.data.run-request.v1 envelope. Replace the two version placeholders with the exact versions from the same data describe response. This example requests an article list for one bounded absolute UTC window:

{
  "schemaVersion": "tiangong.data.run-request.v1",
  "capabilityId": "gdelt.doc-search",
  "capabilityVersion": "<describe.manifest.capabilityVersion>",
  "operationId": "search",
  "operationVersion": "<describe.manifest.operations[0].operationVersion>",
  "input": {
    "query": "(\"climate change\" OR pollution) sourcecountry:us",
    "mode": "artlist",
    "absoluteWindow": {
      "from": "2026-03-01T00:00:00Z",
      "to": "2026-03-07T23:59:59Z"
    },
    "maxRecords": 75,
    "sort": "hybridrel"
  }
}

Use the operation input schema returned by the same data describe response to select a supported mode and its mode-specific fields. Use at most one time-window form; omitting both uses the provider default window. Never silently widen a supplied window or pass arbitrary DOC parameters absent from the schema.

The CLI lints every effective query before network access. Wrap boolean OR groups in parentheses and use exactDomains (domainis:) or domains (domain:), never site: or inurl:. Repeated domains become separate bounded batches. Set continueOnQueryError only when a partial merged result is useful and retain batchQueries plus queryErrors.

Run

tiangong-ai data run gdelt.doc-search search \
  --input /absolute/path/to/request.json --json

The command emits a tiangong.data.run-result.v1 envelope. Preserve its contract, warnings, errors, and receipt with data when handing the result to another workflow.

Result boundaries

Persistent DOC throttling is unavailable retrieval, not zero coverage. When literal topic discovery fits the task, consider the separately described gdelt-web-ngrams-search Skill as an explicit change of retrieval method. It does not support DOC operators or reproduce DOC aggregate timelines.
Treat article-list results as source metadata and links, not downloaded article bodies, verified claims, or independent evidence units.
Treat timelines, tone, language, and source-country outputs as automated aggregates whose meaning depends on the selected mode; do not compare unlike measures or infer causality from them.
In tonechart, articleCount is the count assigned to a tone bin, not the tone score itself and not a public-sentiment estimate.
GDELT source coverage and automated extraction can be uneven. Do not treat counts, tone, or rankings as representative measurements of public opinion, media prevalence, event truth, or sentiment ground truth.
Surface partial, truncation warnings, and empty results. Never reinterpret them as complete absence of coverage.
Use a dedicated GDELT Events, GKG, or Mentions Skill when structured feed rows are required: GKG supplies document annotations, Events supplies coded events, and Mentions links events to documents. This Skill must not invoke or combine them automatically, and their statistics are not interchangeable with DOC.
Cross-source comparison, full-text acquisition, persistence, polling, and research evidence admission belong to the caller or Auto Research.
