deep-research

deep-research is a skill for Claude Code, Codex from Liyux3/scholar-mcp. It costs 49 tokens per session (1,356 once invoked), scanned A, original, Apache-2.0.

A guided workflow for evidence-based literature reviews and technical investigations, using Scholar MCP to search papers, read sources, verify claims, and trace citations.

In plain words
What is it for?
It is for checking claims, comparing benchmarks, mapping a research field, reviewing technical literature, and tracing citation lineages.
Why use it?
It turns an open-ended research question into a staged investigation with explicit sources and follow-up checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deep-research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deep Research

The goal is not just to find facts, but to build an evolving, auditable understanding of a field. Use Scholar MCP for academic discovery, identity resolution, citation traversal, primary-text reading, and selected research memory.

Choose the depth

Mode Starting scope
Focused verification One bounded claim, one or two searches, a small set of decisive primary sources
Technical review Complementary search views, five to eight inspected candidates, two or three expansion seeds
Frontier scan Recent work, active groups, weak signals, counterevidence, and follow-up activity

These are starting budgets. Walk one step, see what's there, then decide the next step. Expand when a new branch can change the field map or conclusion; stop a branch when it repeats known structure or drifts from the question.

Scholar MCP routing

Need Tool
Check live coverage Read scholar://status
Search literature search_papers; preserve the natural-language question and select an intent only when it changes ranking
Recover surveys, foundations, recent work, methods, or datasets search_papers with intent=survey, foundational, recent, method, or dataset
Inspect a paper paper_info with the needed parts of detail,citations,references
Find topical neighbors recommend_papers with relation=similar
Find intellectual peers recommend_papers with relation=peers
Cross vocabulary boundaries recommend_papers with relation=kin
Build a lineage Resolve stable seed IDs, then use build_paper_graph
Read primary evidence read_paper; one call returns the complete extracted paper
Retain a PDF download_paper
Curate durable evidence paper_library for selected papers, notes, tags, collections, and vault export

Scholar routes raw, short, and compressed query forms to different source types. Keep the original question intact. Use source filters when the research question justifies them. Read _meta.source_coverage, _meta.reranker, and degradation details before interpreting an empty or thin result. Enable debug=true when source-level yield, latency, or ranking provenance changes the diagnosis.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deep-research is a skill published in the GitHub repository Liyux3/scholar-mcp (2 stars, last pushed 4d ago), licensed Apache-2.0. It adds 49 tokens to every session and 1,356 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-07.
