News Event Detector

News Event Detector Workflow

Compose the named atomic skills without adding sentiment-scoring logic here.

Inputs

Provide the ticker/universe and the lookback window.

Steps

Step 0: web-search [skill: web-search]

Invoke $web-search with the workflow inputs to locate candidate news events for the universe.

Expected: news_source_packet

Step 1: web-crawler [skill: web-crawler] [depends_on: Step 0]

Invoke $web-crawler with news_source_packet to fetch the full content of the detected articles.

Expected: raw_news_documents

Step 2: citation-auditor [skill: citation-auditor] [depends_on: Step 1]

Invoke $citation-auditor with raw_news_documents to audit reachability and sourcing.

Expected: citation_audit

Output

Return raw_news_documents and citation_audit. Does not classify sentiment or place trades.

Execution

• Run first: Step 0 — $web-search.
• After level 0: Step 1 — $web-crawler.
• After level 1: Step 2 — $citation-auditor.

Execution: If graph-os is reachable, offload the whole DAG via graph_orchestrate action=execute_workflow (or the kg-delegate skill) for true parallel/swarm execution. Otherwise execute the steps natively in dependency order: run steps with no unmet depends_on in parallel, then their dependents.
