What this skill does

# Academic Literature Search

Multi-source academic search with deduplication, DOI resolution, and journal filtering.

**Always read `${CLAUDE_SKILL_DIR}/../google-scholar/domain-knowledge.local.md` before presenting results.**

## IRON LAW: Always Use the Script

**NEVER run the sources manually in sequence. ALWAYS use the research script. This is not negotiable.**

```bash
uv run python3 "${CLAUDE_SKILL_DIR}/scripts/research.py" "<query>" [--n 50] [--min-citations N]
```

The script parallelizes all sources and DOI resolution automatically. Doing it manually serializes everything and triples wall time.

## Sources

| Source | Tool | Strength | Default |
|--------|------|----------|---------|
| `scholar lookup` | Keyword/citation-ranked | Finance classics, foundational papers | ✅ |
| `consensus` CLI | Empirical corpus, sorted by citations | Accounting/finance empirical literature | ✅ |
| Paperpile bib | Personal library (`My Library.bib`) | Papers already in your collection | ✅ |
| `scholar search` | NL semantic | Law reviews, conceptual literature | opt-in (`--scholar-search`) |

`scholar search` is opt-in because it shares rate limits with `scholar lookup` and 429s when run in parallel. Add `--scholar-search` when you specifically want semantic/NL results.

## Output Schema

The script outputs a JSON array. Each paper has:

```json
{
  "title": "...",
  "authors": ["..."],
  "year": 2023,
  "journal": "...",           // original journal label (may be SSRN)
  "journal_resolved": "...",  // CrossRef-resolved journal (present if SSRN label was resolved)
  "doi": "...",
  "citations": 150,
  "takeaway": "...",
  "url": "...",
  "sources": ["lookup", "consensus"]  // all sources that returned this paper
}
```

## LLM Review Step (After Script)

After running the script, read `${CLAUDE_SKILL_DIR}/../google-scholar/domain-knowledge.local.md` and cross-reference each paper's effective journal (use `journal_resolved` if present, else `journal`) against the trusted list:

- ★ = journal matches trusted list
- Papers in `sources: ["lookup", "consensus"]` (multiple sources) = higher confidence
- Papers from `bib` source = already in user's library (flag with 📚)

### Presentation Format

```
★ [Title](url) — Authors (Year), *Journal*, N citations  [sources]
  > Takeaway: ...

📚 ★ [Title](url) — Authors (Year), *Journal*  [in your library]
  > Takeaway: ...
```

Trusted papers first (sorted by citations desc), then non-trusted in a collapsed table.

## Red Flags — STOP If You Catch Yourself:

| Action | Why Wrong | Do Instead |
|--------|-----------|------------|
| **Running sources manually instead of using the script** | Serializes work, triples wall time | `uv run python3 research.py "<query>"` |
| **Using `mcp__consensus__search`** | Rate-limited to 3 results | Script uses CLI binary automatically |
| **Presenting before reading domain-knowledge.local.md** | User expects ★ signals | Read it first, always |
| **Using `journal` field when `journal_resolved` is present** | SSRN label hides real venue | Always prefer `journal_resolved` |

## Common Patterns

```bash
# Standard search
uv run python3 "${CLAUDE_SKILL_DIR}/scripts/research.py" "mandatory disclosure"

# With citation floor
uv run python3 "${CLAUDE_SKILL_DIR}/scripts/research.py" "poison pill" --min-citations 50

# More results from Consensus
uv run python3 "${CLAUDE_SKILL_DIR}/scripts/research.py" "corporate governance" --n 100

# Disable streaming (wait for all sources, output pretty-printed JSON)
uv run python3 "${CLAUDE_SKILL_DIR}/scripts/research.py" "mandatory disclosure" --no-stream
```

## Streaming Mode (default)

Without `--stream`, the script waits for all four sources before emitting anything — Consensus takes ~60s, so fast sources (bib <1s, Scholar ~10s) sit idle.

With `--stream`, the script emits one NDJSON line per event as it happens:

```json
{"event": "source", "source": "bib", "papers": [...]}
{"event": "source", "source": "scholar-lookup", "papers": [...]}
{"event": "source", "source": "scholar-search", "papers": [...]}
{"event": "source", "source": "consensus", "papers": [...]}
{"event": "final", "papers": [...]}
```

- `source` events: raw papers from each source as it completes (may have duplicates across sources)
- `final` event: deduplicated + CrossRef-resolved unified set

Process `source` events as they arrive to present early results; use `final` for the complete deduplicated list. Pass `--no-stream` for batch mode (pretty-printed JSON after all sources complete).
