BedrockNews

Discover BedrockNews stories with GRIN-aware filters. Filter by verdict ('extractive' | 'mixed' | 'generative'), plumb range (0-100 analytical-clarity score), editorialMode ('grin' news/politics | 'culture' | 'research' | 'ledger'), category (see list_categories), date window (since/before, ISO 8601), or a title search (substring match on titles, not full text). Sorted newest first; paginated via cursor. Returns compact story briefs — use get_article for full analysis.

Fetch one BedrockNews story by id. Returns the transformed article plus its full structured analysis (GRIN scores, extraction graph, key stats, trajectory, what-to-watch). Pass fields:'grin' to get just the analysis payload without the heavy body text. Story ids contain slashes (e.g. 'ledger/2026/apr/06/iran-war-math-doesnt-work') — pass them verbatim.

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "description": "The story id, verbatim (ids contain slashes)"
    },
    "fields": {
      "type": "string",
      "description": "Optional projection: 'grin' for the analysis-only view"
    }
  },
  "required": [
    "id"
  ]
}

Return a story's extraction map as a real graph — nodes + edges data, not a picture. This is the load-bearing artifact for agents: re-render it in any style, or analyze who extracts value from whom. 'Not found' can mean the story has no graph (culture/research modes, or older transforms).

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "description": "The story id, verbatim (ids contain slashes)"
    }
  },
  "required": [
    "id"
  ]
}

The BedrockNews category taxonomy: ids (valid values for list_stories' category filter), display names, and which editorial framework each category runs (grin | culture | auto).

BedrockNews metadata: what the site is, how the GRIN/CLAIMS/NOVEL frameworks work, terms of use + attribution, and every machine-readable surface. Also returns the full capability map (every tool, prompt, and resource) — call this first.
