STORM long-form research article

Use the four phase workflow from Stanford STORM: research, outline, write, and polish. The workflow is runtime-neutral and uses whatever search, fetch, prompt, and worker capabilities are actually available. Read references/engine.md before any phase; it is the shared contract for artifacts, resumption, retrieval, and citations.

The default deliverable is a source-grounded article. A user-provided local corpus may be the only source pool when --docs-only is selected. A user who asks for an unsourced creative article should be routed to ordinary writing instead of using this skill.

Invocation and phases

For a complete run, accept:

storm <topic> [--max-perspective N] [--max-turns N]
  [--output-dir PATH | --save] [--docs DIR] [--docs-only]
  [--force] [--retriever mcp|web|local]

Honor a request for one phase (research, outline, write, or polish) and operate only on its existing run directory. The phase references define their arguments and prerequisites:
