Deepxiv Agent Skill

DeepXiv Paper Search & Progressive Reading

Search topic or paper ID: $ARGUMENTS

Role & Positioning

DeepXiv is the progressive-reading literature source:

| Skill | Source | Best for |

|-------|--------|----------|

| /arxiv | arXiv API | Batch search, PDF download, metadata |

| /deepxiv | DeepXiv SDK | Progressive section-level reading |

| /semantic-scholar | S2 API | Published venue metadata, citation counts |

| /alphaxiv | alphaxiv.org | Instant LLM-optimized summary of one paper, with LaTeX source fallback |

Use DeepXiv when you want to inspect papers incrementally instead of loading the full text immediately.

Constants

• DEEPXIV_FETCHER — canonical name deepxiv_fetch.py, resolved per

shared-references/integration-contract.md §2

(Codex-side chain: $ARIS_REPO/tools/ → tools/ → ~/.codex/skills/deepxiv/).

Policy D1 — if unresolved (canonical chain exhausted), fall back to raw deepxiv CLI.

• MAX_RESULTS = 10 — Default number of search results.

> Overrides (append to arguments):

> - /deepxiv "agent memory" - max: 5

> - /deepxiv "2409.05591" - brief

> - /deepxiv "2409.05591" - head

> - /deepxiv "2409.05591" - section: Introduction

> - /deepxiv "trending" - days: 14 - max: 10

> - /deepxiv "karpathy" - web

> - /deepxiv "258001" - sc

Setup

DeepXiv is optional:

pip install deepxiv-sdk

On first use, deepxiv auto-registers a free token and stores it in ~/.env.

Workflow

Step 1: Parse Arguments

Parse $ARGUMENTS for:

• a paper topic, arXiv ID, or Semantic Scholar ID
• - max: N
• - brief
• - head
• - section: NAME
• - trending
• - days: 7|14|30
• - web
• - sc

If the input looks like an arXiv ID and no explicit mode is provided, default to brief.

Step 2: Locate the Adapter

Resolve $DEEPXIV_FETCHER via the canonical strict-safe Codex chain

(see shared-references/integration-contract.md §2):

if [ -z "${ARIS_REPO:-}" ] && [ -f .aris/installed-skills-codex.txt ]; then
    ARIS_REPO=$(awk -F'\t' '$1=="repo_root"{print $2; exit}' .aris/installed-skills-codex.txt 2>/dev/null) || true
fi
DEEPXIV_FETCHER=""
[ -n "${ARIS_REPO:-}" ] && [ -f "$ARIS_REPO/tools/deepxiv_fetch.py" ] && DEEPXIV_FETCHER="$ARIS_REPO/tools/deepxiv_fetch.py"
[ -z "$DEEPXIV_FETCHER" ] && [ -f tools/deepxiv_fetch.py ] && DEEPXIV_FETCHER="tools/deepxiv_fetch.py"
[ -z "$DEEPXIV_FETCHER" ] && [ -f ~/.codex/skills/deepxiv/deepxiv_fetch.py ] && DEEPXIV_FETCHER="$HOME/.codex/skills/deepxiv/deepxiv_fetch.py"

# Smoke test (optional): resolved-but-non-functional adapter is not currently auto-demoted.
if [ -n "$DEEPXIV_FETCHER" ]; then
  echo "DeepXiv adapter resolved at: $DEEPXIV_FETCHER" >&2
else
  echo "DeepXiv adapter unresolved (canonical chain exhausted); raw deepxiv CLI fallback will be used." >&2
fi

If the adapter is unresolved, fall back to raw deepxiv commands.

Step 3: Execute the Minimal Command

[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" search "QUERY" --max MAX_RESULTS
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" paper-brief ARXIV_ID
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" paper-head ARXIV_ID
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" paper-section ARXIV_ID "SECTION_NAME"
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" trending --days 7 --max MAX_RESULTS
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" wsearch "QUERY"
[ -n "$DEEPXIV_FETCHER" ] && python3 "$DEEPXIV_FETCHER" sc "SEMANTIC_SCHOLAR_ID"

Fallbacks:

deepxiv search "QUERY" --limit MAX_RESULTS --format json
deepxiv paper ARXIV_ID --brief --format json
deepxiv paper ARXIV_ID --head --format json
deepxiv paper ARXIV_ID --section "SECTION_NAME" --format json
deepxiv trending --days 7 --limit MAX_RESULTS --output json
deepxiv wsearch "QUERY" --output json
deepxiv sc "SEMANTIC_SCHOLAR_ID" --output json

Step 4: Present Results

For search results, present a compact literature table. For paper reads, summarize the title, authors, date, TLDR, and the next recommended depth step.

Step 5: Escalate Depth Only When Needed

Use the progression:

• search
• paper-brief
• paper-head
• paper-section

Only read the full paper when the user explicitly needs it.

Step 6: Update Research Wiki (if active)

If the project has an active research wiki and the user is building a literature set, add DeepXiv findings as source-backed entries with arXiv/Semantic Scholar IDs, retrieved sections, and the recommended next depth step.

Follow shared-references/integration-contract.md. If the wiki path or schema is unclear, ask before writing.

Key Rules

• Prefer the adapter script over raw deepxiv commands when available.
• If DeepXiv is missing, give the install command and suggest /arxiv or /research-lit "topic" - sources: web.
• Use DeepXiv as an additive source, not a replacement for existing ARIS literature tooling.
• If the result overlaps with a published venue paper from Semantic Scholar, keep the richer venue metadata in the final summary.
