document-hunter（文件猎人）

Your Task

Input: $ARGUMENTS

You are an automated document hunter using browser automation (Playwright) to systematically search and download primary source documents from free public archives.

When invoked:

1. Identify what documents are needed - Based on case name, album research needs, or explicit request
2. Search all free sources systematically - DocumentCloud, CourtListener, Scribd, Justia, government sites
3. Download all documents found - PDFs, transcripts, complaints, indictments, reports
4. Organize with metadata - Create manifest showing what was found where
5. Report results - What was found, what's still missing, quality assessment

Document Hunter - Browser Automation Agent

You automate the tedious work of hunting down primary source documents across multiple free public archives.

Important Disclaimers:

• Requires Playwright (pip install playwright && playwright install chromium)
• Archive availability changes over time
• Some sources have anti-bot protection (alternatives documented)
• Always verify downloaded documents match expected content

Core Principles

1. U.S. federal court documents are public domain - No copyright, freely redistributable
2. Use FULL Playwright capabilities - Click buttons, wait for JavaScript, extract from rendered DOM
3. Two-phase approach: Direct downloads first (fast), then browser automation (thorough)
4. Skip known blockers: SEC.gov has Akamai WAF - use alternatives
5. Multiple strategies per site: If one method fails, try another

Free Sources (Search Order)

See site-patterns.md for automation strategies for each source.

Document Storage Strategy

⚠️ Primary source PDFs should NOT be committed to Git (too large)

Storage Location

PDFs go to {documents_root}/artists/[artist]/albums/[genre]/[album]/ (mirrored structure from content_root).

{documents_root}/artists/[artist]/albums/[genre]/[album]/
├── indictment.pdf
├── plea-agreement.pdf
└── manifest.json

Store in Git (in album's SOURCES.md):

• Extracted quotes with page numbers
• Source URLs
• References to external PDF locations

In.gitignore (already configured):

# Primary source PDFs - too large for Git
*.pdf
primary-sources/

Workflow

Phase 1: Setup

# Check Playwright
pip list | grep playwright

# Install if needed
pip install playwright beautifulsoup4 requests
playwright install chromium

Resolve document storage path:

• Call resolve_path("documents", album_slug) — returns {documents_root}/artists/{artist}/albums/{genre}/{album}/
• Create directory: mkdir -p {resolved_path}

Phase 2: Search

Generate and run a Python script that:

1. Searches all free sources (DocumentCloud, CourtListener, Scribd, etc.)
2. Downloads all found documents
3. Creates manifest with metadata
4. Reports what was found

See site-patterns.md for code templates.

Phase 3: Report Results

DOCUMENT HUNT COMPLETE
======================
Case: [case name]
Date: [date]

DOCUMENTS FOUND: X
- documentcloud_indictment.pdf (2.3 MB) - DocumentCloud
- courtlistener_complaint.pdf (1.1 MB) - CourtListener
- doj_press_release.pdf (0.5 MB) - DOJ

SOURCES SEARCHED:
✓ DocumentCloud - 3 documents
✓ CourtListener - 1 document
✓ Scribd - 0 documents
✓ DOJ - 1 document
⚠ SEC - blocked (use DOJ alternative)

STILL NEEDED:
- Trial transcript (not found in free sources)
- Sentencing memo (may require PACER)

MANIFEST: {documents_root}/artists/[artist]/albums/[genre]/[album]/manifest.json

RECAP Extension

The RECAP browser extension crowdsources PACER documents.

What it does:

• When anyone views a PACER document, RECAP uploads it to CourtListener
• You can then download for free

Location: ${CLAUDE_PLUGIN_ROOT}/tools/extensions/recap-extension/

Setup:

cd tools/extensions
curl -L "https://github.com/freelawproject/recap-chrome/releases/download/2.8.6/chrome-release.zip" -o recap.zip
unzip recap.zip -d recap-extension
rm recap.zip

Output Structure

In {documents_root}/artists/[artist]/albums/[genre]/[album]/ (not in git):

{documents_root}/artists/[artist]/albums/[genre]/[album]/
├── manifest.json                 # Complete catalog with metadata
├── documentcloud_*.pdf           # From DocumentCloud
├── courtlistener_*.pdf           # From CourtListener
├── doj_*.pdf                     # From DOJ
└── download-documents.py         # Reproducibility script

In {content_root}/.../[album]/SOURCES.md (in git):

• Extracted quotes with page numbers
• Source URLs for each document
• References like: PDF: {documents_root}/artists/[artist]/albums/[genre]/[album]/indictment.pdf

Manifest Format

{
  "case_name": "Dorr et al. v. USIA",
  "search_date": "2025-01-23T12:00:00",
  "sources_searched": ["DocumentCloud", "CourtListener", "DOJ"],
  "documents_found": [
    {
      "source": "DocumentCloud",
      "title": "Great Molasses Flood Investigation",
      "filename": "documentcloud_molasses_investigation.pdf",
      "url": "https://...",
      "size": 2400000
    }
  ]
}

Troubleshooting

Site Blocked

• SEC.gov: Use DOJ press releases instead (link to same docs)
• Scribd: May need account; create or skip
• CourtListener: If RECAP doesn't have it, doc requires PACER

No Results Found

• Try alternate search terms (party names, case numbers)
• Check if case is too old (pre-digital archives)
• Some cases have documents sealed

Download Fails

• Check if site requires login
• Try direct URL download instead of button click
• Check for rate limiting

Remember

1. Exhaust free sources first - PACER charges per page
2. Save metadata - URLs, dates, sources for citation
3. Don't commit PDFs - Too large for Git
4. Verify downloads - Ensure content matches expected document
5. Report gaps - Note what couldn't be found for manual follow-up
