Exa AI-Powered Web Search

Search query: $ARGUMENTS

Role & Positioning

Exa is the **broad web search** source with built-in content extraction:

| Skill | Best for | |------|----------| | `/arxiv` | Direct preprint search and PDF download | | `/semantic-scholar` | Published venue papers (IEEE, ACM, Springer), citation counts | | `/deepxiv` | Layered reading: search, brief, section map, section reads | | `/exa-search` | Broad web search: blogs, docs, news, companies, research papers — with content extraction |

Use Exa when you need results beyond academic databases, or when you want content (highlights, full text, summaries) extracted alongside search results.

Constants

• **EXA_FETCHER** — canonical name `exa_search.py`, resolved per

[`shared-references/integration-contract.md`](../shared-references/integration-contract.md) §2 (Policy D1 — standalone `/exa-search` has no documented fallback, so unresolved helper terminates with an explicit error).

• **MAX_RESULTS = 10** — Default number of results to return.

> Overrides (append to arguments): > - `/exa-search "RAG pipelines" — max: 5` — top 5 results > - `/exa-search "diffusion models" — category: research paper` — research papers only > - `/exa-search "startup funding" — category: news, start date: 2025-01-01` — recent news > - `/exa-search "transformer" — content: text, max chars: 8000` — full text mode > - `/exa-search "transformer" — content: summary` — LLM-generated summaries > - `/exa-search "transformer" — domains: arxiv.org,huggingface.co` — domain filter > - `/exa-search "https://arxiv.org/abs/2301.07041" — similar` — find similar pages

Setup

Exa requires the `exa-py` SDK and an API key:

pip install exa-py

Set your API key:

export EXA_API_KEY=your-key-here

Get a key from [exa.ai](https://exa.ai).

Workflow

Step 1: Parse Arguments

Parse `$ARGUMENTS` for:

• **query**: The search query (required) or a URL (for `find-similar` mode)
• **similar**: If present, use `find-similar` mode instead of search
• **max**: Override MAX_RESULTS
• **category**: `research paper`, `news`, `company`, `personal site`, `financial report`, `people`
• **content**: `highlights` (default), `text`, `summary`, `none`
• **max chars**: Max characters for content extraction
• **type**: Search type — `auto` (default), `neural`, `fast`, `instant`
• **domains**: Comma-separated include domains
• **exclude domains**: Comma-separated exclude domains
• **include text**: Phrase that must appear in results
• **exclude text**: Phrase to exclude from results
• **start date**: ISO 8601 date — only results after this
• **end date**: ISO 8601 date — only results before this
• **location**: Two-letter ISO country code

Step 2: Locate Script

Resolve `$EXA_FETCHER` via the canonical strict-safe chain (see [`shared-references/integration-contract.md`](../shared-references/integration-contract.md) §2). Policy D1 cascade: there is no native inline fallback for Exa (retrieval requires the `exa-py` SDK + API key, which lives in the fetcher), so unresolved helper means the SKILL cannot produce its primary output — fail with explicit remediation.

cd "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" || exit 1
if [ -z "${ARIS_REPO:-}" ] && [ -f .aris/installed-skills.txt ]; then
    ARIS_REPO=$(awk -F'\t' '$1=="repo_root"{print $2; exit}' .aris/installed-skills.txt 2>/dev/null) || true
fi
if [ -z "${ARIS_REPO:-}" ] && [ -f "$HOME/.aris/repo" ]; then
    ARIS_REPO=$(cat "$HOME/.aris/repo" 2>/dev/null) || true
fi
EXA_FETCHER=".aris/tools/exa_search.py"
[ -f "$EXA_FETCHER" ] || EXA_FETCHER="tools/exa_search.py"
[ -f "$EXA_FETCHER" ] || { [ -n "${ARIS_REPO:-}" ] && EXA_FETCHER="$ARIS_REPO/tools/exa_search.py"; }
[ -f "$EXA_FETCHER" ] || {
  echo "ERROR: exa_search.py not resolved at .aris/tools/, tools/, \$ARIS_REPO/tools/, or via ~/.aris/repo." >&2
  echo "       Fix: rerun bash tools/install_aris.sh or smart_update.sh (refreshes ~/.aris/repo), export ARIS_REPO, or copy the helper to tools/." >&2
  echo "       Also ensure 'exa-py' is installed: pip install exa-py" >&2
  exit 1
}

Step 3: Execute Search

**Standard search:**

python3 "$EXA_FETCHER" search "QUERY" --max 10 --content highlights

**With filters:**

python3 "$EXA_FETCHER" search "QUERY" --max 10 \
  --category "research paper" \
  --start-date 2025-01-01 \
  --content text --max-chars 8000

**Find similar pages:**

python3 "$EXA_FETCHER" find-similar "URL" --max 5 --content highlights

**Get content for known URLs:**

python3 "$EXA_FETCHER" get-contents "URL1" "URL2" --content text

Step 4: Present Results

Format results as a structured table:

| # | Title | Authors | Venue/Publisher | URL | Date | Key Content |
|---|-------|---------|-----------------|-----|------|-------------|

For each result:

• Show title and URL
• Show published date if available
• Show highlights, text excerpt, or summary depending on content mode
• Flag particularly relevant results
• **For `category: "research paper"` hits only** — also record authors

(from Exa's `author`/`authors` fields, or fallback: parse from the result snippet) and venue/publisher (from `publisher`, `source`, or the domain hosting the paper). These are needed by Step 6's wiki hook; if either is unavailable for a given hit, skip wiki ingest for that one hit and log a note.

Step 5: Offer Follow-up

After presenting results, suggest:

• **Deepen**: "I can fetch full text for any of these results"
• **Find similar**: "I can find pages similar to any result"
• **Narrow**: "I can re-search with domain/date
