Gdelt

gdelt

Response language: match user input.

⚠️ GDELT is a rolling recent-window API, not a historical event archive. Time windows are anchored to absolute timestamps (UTC) for reproducibility — the same query asked tomorrow will return different results.

⚠️ 5-second throttle between requests (enforced). Plan batches accordingly.

When to use

Trigger phrases:

• 全球新闻 / 全球事件 / 多语种新闻
• 媒体 tone / sentiment trend / 国际关系
• geopolitical / event tone
• GDELT

Useful for "what is the world saying about X right now" — i.e. retrieving articles from non-English / non-financial sources that don't surface in Longbridge's curated newsfeed.

Workflow

1. Build a query in GDELT DSL (the user's term, optionally with operators like domain:bloomberg.com, sourcelang:eng).
2. Pick a mode:
   • artlist — list of articles (default).
   • timelinetone — per-15-min tone time series (-10 = very negative, +10 = very positive).
   • timelinevol / timelinevolinfo — article volume over time.
   • tonechart — tone histogram.
3. Specify the window — prefer --start/--end (absolute), fall back to --timespan. The script converts relative timespans to absolute timestamps before the call and echoes them in meta.window so the journal can be re-run.

CLI examples

# Articles about Nvidia in the last 24h
python3 .claude/skills/gdelt/scripts/doc.py "Nvidia"

# 7-day window, English + Chinese articles about TSMC
python3 .claude/skills/gdelt/scripts/doc.py "TSMC OR \"Taiwan Semiconductor\"" --timespan 7d --lang eng,zho

# Tone timeline for Federal Reserve over 30 days
python3 .claude/skills/gdelt/scripts/doc.py "Federal Reserve" --mode timelinetone --timespan 30d

# Absolute window
python3 .claude/skills/gdelt/scripts/doc.py "AI chips" --start 20260501000000 --end 20260528000000

Error handling

Known limitations

• 5-second minimum between requests; batch tone + artlist queries must be sequenced.
• --max-records cap is 250.
• GDELT's tone metric is a heuristic — useful for direction-of-narrative, not ground truth.
• Results are not cached (window-sensitive).
