# Research Acquire Command

Download research papers from public repositories and extract metadata.

## Instructions

When invoked, perform automated paper acquisition:

1. **Identify Source**
   - Parse DOI, arXiv ID, or URL
   - Determine paper hosting location
   - Check if paper already exists in `.aiwg/research/sources/`

2. **Download Paper**
   - Attempt direct PDF download from source
   - Try fallback sources (arXiv mirror, Unpaywall, PMC)
   - Save to `.aiwg/research/sources/[ref-id].pdf`
   - Verify download integrity (file size, PDF structure)

3. **Extract Metadata**
   - Parse PDF metadata (title, authors, year)
   - Query CrossRef/Semantic Scholar for enhanced metadata
   - Extract abstract, keywords, citation count
   - Determine source type (journal, conference, preprint)

4. **Generate Frontmatter**
   - Create YAML frontmatter per @agentic/code/frameworks/sdlc-complete/schemas/research/frontmatter-schema.yaml
   - Assign REF-XXX identifier
   - Calculate PDF checksum (SHA-256)
   - Set initial GRADE baseline from source type

5. **Create Finding Document**
   - Generate `.aiwg/research/findings/REF-XXX-[slug].md` from template
   - Populate frontmatter with extracted metadata
   - Add placeholder sections for key findings
   - Update fixity manifest

6. **Post-Acquisition**
   - Log acquisition in `.aiwg/research/acquisition-log.yaml`
   - Update corpus index
   - Suggest next steps (quality assessment, documentation)

## Arguments

- `[identifier]` - DOI, arXiv ID, or URL (required)
- `--output [path]` - Custom output location (default: auto-generate)
- `--ref-id [REF-XXX]` - Specific REF-XXX identifier (default: auto-assign)
- `--extract-text` - Extract full text to `.txt` file for analysis
- `--no-metadata` - Skip metadata enrichment
- `--force` - Re-download even if paper exists

## Examples

```bash
# Acquire by DOI
/research-acquire 10.48550/arXiv.2308.08155

# Acquire by arXiv ID
/research-acquire arXiv:2308.08155

# Acquire with custom identifier
/research-acquire https://arxiv.org/pdf/2308.08155.pdf --ref-id REF-022

# Acquire with full text extraction
/research-acquire 10.1145/3377811.3380330 --extract-text
```

## Expected Output

## Provenance Tracking

All acquisitions create provenance records:

```yaml
# .aiwg/research/provenance/records/REF-022-acquisition.yaml
entity:
  id: "urn:aiwg:artifact:.aiwg/research/sources/REF-022.pdf"
  type: "research_paper"

activity:
  id: "urn:aiwg:activity:acquisition:REF-022:001"
  type: "acquisition"
  started_at: "2026-02-03T12:00:00Z"
  ended_at: "2026-02-03T12:00:15Z"

agent:
  id: "urn:aiwg:agent:acquisition-agent"
  type: "aiwg_agent"

source:
