# Collecting Sources Phase 1 of two-phase research: discover, evaluate, and store sources with metadata. Synthesis (Phase 2) and fact-checking (Phase 3) are separate phases — this skill ends at handoff. Everything lands in the task workspace: ``` work/<task-id>/ ├── source_index.md # human-readable catalogue └── sources/ ├── papers/ # academic papers (.txt from CORE/Unpaywall, .pdf from arXiv) ├── web/ # web pages (Markdown) ├── blogs/ # blog posts (Markdown) └── docs/ # documentation (Markdown/HTML) ``` Every source file has a `.meta.yaml` companion conforming to schema v1.0 — fields, missing-data conventions, and a complete example in `references/source-metadata-schema.md`. ## 1 — Setup - `mkdir -p work/<task-id>/sources/{papers,web,blogs,docs}` - Source IDs are sequential and zero-padded: `src_001`, `src_002`, … - If `source_index.md` exists from a previous collection, load it for duplicate detection. ## 2 — Discovery **Detect the domain** from the research question: - **Academic**: "paper", "study", "peer-reviewed", "journal"; biomedical (clinical, drug, patient), CS/physics (algorithm, neural network, quantum), social sciences (policy, governance, economics); academic URLs given (arxiv.org, doi.org, pubmed.gov) - **General web**: "tutorial", "guide", "how-to", documentation focus, no academic terminology **Academic research** — discovery finds papers and extracts **identifiers** (DOI, arXiv ID, PubM
