deep-research

deep-research is a skill for Claude Code, Codex from rongarede/claude-skills-research. It costs 66 tokens per session (2,333 once invoked), scanned A, a copy of deep-research, MIT.

A guided process for producing research reports with controlled formats, tracked evidence, citations, and review stages. It covers source collection, source comparison, outlining, drafting, and citation checks.

In plain words
What is it for?
Use it for research reports, literature reviews, market or industry analysis, policy briefs, and technical briefs. It supports gathering sources, extracting information from PDFs, combining drafts, and checking citations.
Why use it?
It reduces the risk of losing track of where claims came from or producing a report that does not follow the required structure. It also breaks large research jobs into repeatable stages.

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 1 finding 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 11d 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.

Deep Research

Create high-fidelity research reports with strict format control, evidence mapping, and multi-pass synthesis.

Quick Start

  1. Clarify the report spec and format contract
  2. Build a research plan and query set
  3. Collect evidence with parallel agents (multi-source) 3.5. Download source PDFs (arXiv + sci-hub)
  4. Triage sources and build an evidence table 4.5. Extract paragraphs from downloaded PDFs
  5. Outline and section map
  6. Multi-pass full drafting (parallel subagents)
  7. UNION merge, enforce format compliance, verify citations
  8. Evidence and citation verification
  9. Present draft for human review and iterate

Core Workflow

Copy this checklist and track progress:

Deep Research Progress:
- [ ] Step 1: Intake and format contract
- [ ] Step 2: Research plan and query set
- [ ] Step 3: Evidence collection (parallel agents)
- [ ] Step 3.5: PDF download (arXiv + sci-hub)
- [ ] Step 4: Source triage and evidence table
- [ ] Step 4.5: PDF paragraph extraction
- [ ] Step 5: Outline and section map
- [ ] Step 6: Multi-pass full drafting (parallel subagents)
- [ ] Step 7: UNION merge and format compliance
- [ ] Step 8: Evidence and citation verification
- [ ] Step 9: Present draft for human review and iterate

Step 1: Intake and Format Contract

Establish the report requirements before any research:

  • Confirm audience, purpose, scope, time range, and geography
  • Lock output format: Markdown, DOCX, slides, or user-provided template
  • Capture required sections and exact formatting rules
  • Confirm citation style (footnotes, inline, numbered, APA, etc.)
  • Confirm length targets per section
  • Ask for any existing style guide or sample report

Create a concise report spec file:

Report Spec:
- Audience:
- Purpose:
- Scope:
- Time Range:
- Geography:
- Required Sections:
- Section Formatting Rules:
- Citation Style:
- Output Format:
- Length Targets:
- Tone:
- Must-Include Sources:
- Must-Exclude Topics:

If a user provides a template or an example report, treat it as a hard constraint and mirror the structure.

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 rongarede/claude-skills-research (2 stars, last pushed 5mo ago), licensed MIT. It adds 66 tokens to every session and 2,333 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 83% identical to deep-research, differing in 107 lines, and is treated as a copy.
